How to choose the right soldering iron power

How to choose a soldering iron for your home

This article will only consider electric soldering irons for soldering wires and radio components. The main condition before choosing a soldering iron for your home is its weight. With a heavy soldering iron, it will be inconvenient to orient the brush when working, and your hand will quickly get tired.

Therefore, the weight of the soldering iron should be small for convenient and long-term operation. Branded soldering irons weigh only a few tens of grams and have decent power. It makes no sense to list the names of companies, since there are a great many of them. You need to choose electric soldering irons based on a number of their technical characteristics and design.

The handle of the soldering iron greatly influences the duration of work and the quality of soldering. The handle can be made of plastic, ebonite and wood. Plastic handles can become hot, making operation uncomfortable. There are plastic handles with holes for hot air to escape. For soldering irons with a power of up to 30 W, this parameter is not critical, since the plastic does not heat up much at such power.

For high power values ​​of the soldering iron, the handle should be ebonite or wooden. The ebonite handle is quite heavy, but for high-power soldering irons this is acceptable. A wooden handle is lighter than an ebonite handle and has excellent heat-insulating properties, but does not have a beautiful design.

Domestic soldering irons with wooden handle

There are two types of heating elements This is a heating element made of a nichrome spiral and a ceramic heater. A soldering iron with a regular nichrome spiral has mica layers on which the spiral is wound. More mica is wound on top of the spiral.

Soldering irons with a ceramic heater are more technologically advanced, but they have a drawback. Ceramics are fragile and are susceptible to falling. But if you handle such a soldering iron with care, it will last a long time. If a nichrome spiral burns out, then winding it yourself is problematic. Ceramic heaters are commercially available. Replacing them will not be difficult.

A soldering iron tip is a working tool on which the quality of soldering and the durability of the soldering iron depend. The tip is usually made of copper. The copper tip burns over time and shells appear. It is processed with a fine file to its original appearance. There is also a fireproof tip, which has a longer service life.

Tips for various types of soldering work

Soldering irons with fireproof tips are produced by foreign companies; there are no domestic soldering irons with such a tip. The tip can be sharpened under a flat screwdriver or under an oblique cut. A tip sharpened for shearing or a flat-head screwdriver is used for soldering wires. A conical tip is convenient for soldering radioelements on printed circuit boards and thin wires. The tip can be removable and retractable.

The retractable copper tip is sharpened as it burns and extended to the required length. The sting burns not only at the end, but along the entire length. Therefore, it must be periodically removed and cleaned of carbon deposits. Otherwise, it will become so stuck that it will be impossible to remove it. The removable tip can be easily replaced with a new one. For most types of work, a direct tip is used. For spot soldering, the tip is bent at an angle of 60 per third of the length.

How to choose the power of a soldering iron

Soldering irons can be divided into groups based on power.

1. Up to 10 W. This soldering iron works with small radioelements and thin wires.

2. 15-30 watt soldering irons are also used to work with electronic boards and small cross-section wires.

3. With a 40 - 60 watt soldering iron, you can solder wires at home.

4. 80 - 100 watts of soldering iron power is enough to solder large cross-section wires.

5. 200 Watt is a hammer-type soldering iron, which is designed for soldering massive metal elements and wires.

Soldering station with hair dryer and soldering iron

For electrical work in the house, it is correct to choose a soldering iron of 40 - 60 W. To work with electronic boards, soldering stations with temperature control of the soldering iron tip are used. You can use branded soldering irons with a power of up to 30 W, and a temperature control circuit built into the soldering iron handle and a supply voltage of 24 - 36 V.

All soldering irons intended for soldering radioelements and transistor microcircuits must be grounded. This requirement is necessary in order to neutralize static charge, which is dangerous for field-effect circuits and transistors.

Also, soldering irons designed to work with radioelements must operate at a voltage of 24 or 36 V AC.

A soldering iron of 40 - 60 W is suitable for home use, and if you have some kind of hobby, then you need to purchase another soldering iron that matches the power of your hobby.

The power cord should be long and flexible so that it does not interfere with the movement of the hand when soldering and matches the power of the soldering iron.

Domestic manufacturers are inferior in quality of soldering irons to foreign companies, so many focus on a large selection of foreign products, including Chinese ones. Self-respecting soldering iron manufacturers also offer a high-quality soldering iron stand in the kit.

How to choose a soldering iron for soldering wires?

There is no particular need to have this device as a tool at home today. If there is a breakdown of household appliances, cell phones, radio equipment, you can always turn to specialists, take the broken item to a service center, and not everyone understands complex electronics. The work requires skills and painstaking work when soldering small parts.

Soldering, of course, is a necessary and interesting activity; if you want to learn how to use the device correctly, you should familiarize yourself with the soldering iron more closely by reading detailed instructions about the types, the operating principle of the device, its purpose in everyday life and use in different spheres of human activity.

Soldering iron - what is it

An electric soldering iron is a hand-held device designed for fastening metal components together by soldering. Soldering materials for joining metals are tin, copper, lead, and nickel. When heated, the alloys turn into a liquid state and fill small voids and gaps, firmly soldering the parts together.

Description of the device

The electrical appliance consists of:

• rod;
• heater;
• stings;
• holder;
• electrical cord with plug for connecting to the network.

The soldering iron operates on a 220 W network; in industry, models with a power of 360, 680, 850, 1200 W are used. It is designed for soldering parts for household or industrial purposes and is designed to connect various metal elements with each other. It is widely used in electronics and radio engineering. .

An electric heating element in the form of a nichrome spiral in a mica and ceramic shell is built into the device. The element is protected from above by a metal casing so that the worker does not accidentally get an electric shock.

Principle of operation

The operating principle is simple:

1. The soldering iron is connected to the network.
2. When the device is turned on, the red copper rod heats up to the temperature at which the solder begins to melt.
3. Next, the heat is transferred to the tip of the device. When the copper tip comes into contact with the solder, it melts, the parts heat up and are soldered together.

Areas of use

The soldering iron is widely used in industry for soldering microcircuits in telephones, radios, televisions, copper pipes, and wires. At home for repairing copper utensils and small parts.

Kinds

Soldering irons are:

• Electric , with a durable and practical spiral heater. With the help of an electric station, you can solder quickly and efficiently, but a beginner cannot operate it; experience in operation and a number of practical skills are required.
• Ceramic , with a more powerful heater in the device.
• Induction , heating of which is carried out by an inductor coil. The coil creates a magnetic field for the tip, as a result of which the cores heat up and soldering can begin. Loss of magnetic properties will lead to the cessation of heating. These soldering irons are significantly expensive, unreliable and far from practical.
• Self-contained , the solder for the device is gas.
• Rechargeable , operating at low power of only up to 15 W.
• Pulse , in the form of a pistol. Press the trigger and hold it until the tip heats up to a certain temperature. When the trigger is pulled, the device stops heating and begins to cool slowly.

Purpose

• for pipes of sewerage systems and water supply systems in case of cracks and crevices that promote water leakage;
• for the home, you can solder leaky dishes, small metal utensils, welding cables;
• for microcircuits, small chips in electronics, body - radio devices, car wires, connectors.

Criterias of choice

When choosing a device, consider the following characteristics:

• Heater type.
• Power. The traditional power of the device for soldering, desoldering microcircuits is from 3 to 12 W, for soldering household appliances - from 20 to 40 W, for soldering with large cross-section wire - from 60 to 100 W, for soldering dishes, a radiator in a car, metal products large sizes - from 100 to 150 W. If you need a device for use at home, in everyday life, then it is better to purchase two at once, with different power. Depending on the breakdown, successful and durable soldering may require a device with a low power of up to 40 W; for large-scale work, a more powerful device will be required - up to 100 W.
• The supply voltage is usually standard - 220 W. Many models are designed to operate precisely at this voltage. For uninformed users, everything is the same and there is a lot of it; small appliances for household needs with a voltage no higher than 36 - 40 W are safer. If there is no outlet, or you need to solder in a hard-to-reach place, it is better to choose a device with 12.18.24 power supply, or purchase a gas model.
• The shape and heat resistance of the tip are very important when choosing this device. On sale, the sting can be found in any shape in the form of a spatula, cone, or needle. Using a spatula is much easier and more convenient. Buy a set of tips; it is better to solder microcircuits with a flat, wide tip; flat, thin conical tips will also find their use over time.

When choosing a soldering iron, it is important to take into account the heat resistance of the tip, which is resistant to sudden heating and sudden temperature changes. Choose heat-resistant tips; the soldering iron will last longer.

When choosing, pay attention to the handle; it should be thermally insulated from the main heating part, and the handle should also adjust the length of the tip itself.

An electric soldering iron can heat up to 300 degrees; do not place it hot on a table surface. It’s good if, in addition to the device when purchasing, you purchase a special stand, there will be no damage to property or possible ignition of the structure.

Tips and tricks for choosing a soldering iron

1. If you are familiar with the device and have certain skills, then immediately purchase a soldering station.

   Unlike a simple electric model, using a station you can:

   • you won’t be able to control the heating range and burn elements during soldering;
   • maintain the tip temperature at normal levels to avoid overheating;
   • There is no need to purchase the necessary small elements separately; the station is equipped with everything you need: a stand for a soldering iron, a bath for cleaning a sponge.
2. If you are a beginner and need a soldering iron for home purposes, choose a model with a power of no more than 40 W, as well as a temperature control function.
3. Do not buy the first device with many different functions, first learn the basics when working with the device. A simple and inexpensive device is quite suitable for home use.
4. When purchasing, pay attention to the voltage of the soldering iron; models from 12 to 24 W are safer.
5. A good choice if you don’t have certain skills is gas models. After reading the included instructions, you will quickly learn how to use it.
6. Buy the stings in a set. It’s always convenient to have tips of different shapes on hand; they’ll come in handy around the house, you never know what needs to be soldered in the future.
7. When heating the device, only hold the insulated handle, otherwise you may burn your hands.
8. Store the tool on a shelf, perhaps in a pantry, or in a square ceramic pot; small parts will not get lost and will always be assembled.
9. It is better to throw away the waste generated during soldering immediately, do not scatter it on the floor, as you can slip.
10. In addition to the soldering iron, it is better to immediately purchase an additional auxiliary tool in the form of:
    • wire cutters for removing insulation, cutting wires, parts at the terminal;
    • tweezers for moving to the place where small parts are soldered, especially when working with a microcircuit;
    • medical scalpel;
    • stationery knife;
    • thin awl;
    • syringe needles.
11. Only by choosing the right tool will you be able to perform high-quality work and solder parts reliably and durable. The design and power of the device are different. Take into account the main criteria when choosing, read the instructions when purchasing, and the components for the device.
12. Powerful soldering irons are mainly designed for industrial purposes. At home, you will only need to have a device with a power of no more than 100 W.
13. Store the tool in a place away from children.

    Avoid exposure to dampness or leaving the device switched on unnecessarily.

14. Modern models today are equipped with a whole list of additional attachments and bells and whistles, sometimes completely unnecessary in everyday life. When choosing, indicate the purpose of this acquisition. There is absolutely no need to store bulky soldering stations in the apartment, although at the dacha, in the garage, perhaps this unit will become your constant assistant. The soldering iron arsenal on the market is constantly being modified and replenished, so in some cases it will be easier to purchase the necessary parts later, as needed.

Detailed instructions for choosing a soldering iron for the home for all occasions

If the reader is faced with the question of purchasing a soldering iron, then talking about its purpose, structure, and operating principle is a waste of time. Considering that the range of products is significant, and the classification of products according to various parameters is quite complex, it is the process of choosing a soldering iron for home work that is a real problem for many.

This is what we focus the reader’s attention on. The information below will help you buy the right model of soldering iron, the further use of which at the household level will not cause any special problems.

The author first “met” a soldering iron over four decades ago. Since then, both in his work and in everyday life, he has not parted with him. Consequently, he can not only have his own opinion, but also express it. The reader will probably not agree with certain provisions, and this is quite understandable. However, all recommendations are not just “literary processing” of other people’s thoughts. They are based on the author’s personal experience and tested by practice.

A heating element

It can be spiral-shaped and ceramic. The latter type is positioned as one of the innovations in the field of electrical and radio installation, and is actively advertised by manufacturers. What is the difference, and which option is preferable to choose?

Ceramic – With the higher cost of these soldering irons, durability is not guaranteed. The main reason is the fragility of the element. Such models are better suited for use in specialized workshops, laboratories, in short, where the entire work area fits on a specialized table. These soldering irons are sensitive to shock, so it is hardly advisable to purchase them for home use.

The spiral is a long-time-tested design of the heating element. The author sees only advantages - the possibility of repair by replacing it, changing the power of the soldering iron (if necessary) by decreasing (increasing) the length of the spiral. For someone who knows the elementary laws of physics and can independently make calculations, this is not a problem. And such models are cheaper than ceramic analogues.

Sting

This structural element can be different in shape and shade. What to choose?

The best option is a direct sting. This form is considered universal in use and is suitable for almost any technological operation.

The color of the sting can be silver or reddish. A copper-based tip is easier to process. It is easier to remove layers (carbon deposits) from it, sharpen it as needed for a specific job, and bend it if necessary.

Possibility of adjusting the length of the protrusion from the body. A very useful “option” that allows you to extend the service life of the tip without replacing it with a new one.

Soldering iron handle

There are 3 manufacturing options. It is not the form that is meant, but the material.

Plastics. Light weight is a plus, quick warming up is a minus, and a very significant one at that. You won’t be able to hold such a soldering iron in your hands for a long time when it’s plugged in.

Ebonite. The only drawback of these pens is that they are heavy. If you use a high-power soldering iron, for example, a 200-watt so-called “dart,” this is not important. But it’s definitely not suitable for a miniature instrument used for radio editing.

Wood. For the home - the best option. These handles do not overheat and are lightweight. Perhaps someone will note such a drawback as an unpresentable appearance. But how important is this for a soldering iron?

Power cord

The recommendations for this item are as follows:

First, its length should be sufficient so as not to create inconvenience when using the tool.

The second is the flexibility of the cord. During operation, the soldering iron is given different positions. This is what you need to check - how the cord will “react”, whether it will become a hindrance.

The third is isolation. Double protection, from a TB point of view, is much better.

The fourth is a fork. Nowadays they are mostly plastic, which makes them impossible to repair. After all, one of the main “diseases” of soldering irons is a break (fracture) of the wire strands in the plug area, since the tool constantly changes its spatial position. But if it is collapsible, then restoring the functionality of the product is easy.

According to technical characteristics and scope of application

What does this mean? Power, supply voltage and type of soldering iron. When determining the parameters for each item, it is necessary to take into account for what purpose it is purchased. It is from these positions that we will consider all the characteristics.

For working with printed circuit boards

What is special about this installation? It is quite dense, and it is difficult to work with a regular tip. Plus to this is the “tenderness” of the tracks on the boards. The slightest overheating leads to their detachment. Therefore, when choosing a soldering iron specifically for radio installation, it is advisable to choose a pulse model. If you purchase a rod one, then only complete it with a power supply. At its outputs (and there are at least two of them) the voltages are reduced. Depending on the manufacturer - from 6 to 24 V.

Such a soldering iron cannot be the main one for the home, since its use is specific, only for printed circuit boards.

You can also choose a 220 V rod soldering iron, but with less power - 25 W. They won’t be able to do all the “household” jobs, but it will be suitable for most of them. However, radio installation with such a soldering iron can only be carried out by a professional, specially sharpening the tip, and then, as a last resort, in the absence of another tool at hand.

When working with printed circuit boards, using a soldering iron without a ground connection is not recommended. Significant interference can cause breakdown of capacitors and failure of microcircuits, which often happens in practice. Even if it has a power supply, the latter must be grounded.

For wide application

Here for the home, in terms of voltage, there is no particular choice - only from a socket, 220. But in terms of power, opinions vary - from 25 to 80. The author recommends using a 65 W soldering iron. It is universal for household use.

For garage

As a rule, in a home “mini-workshop” the car owner is engaged in soldering wires (cables) and similar work that requires heating the metal to a high temperature. Here, an ordinary rod sample, even at 80 - 100 W, is unlikely to help. It is better to choose a 200 W soldering iron. It has already been mentioned. In addition to the name “dart,” this model for home use is often called an “electric hammer” (based on its shape). For “rough” soldering it is an indispensable thing.

Experience shows that there should be at least 2 soldering irons in the house. The main one is at 65 (40)/220, and the additional one (s) is depending on the hobbies (hobbies, etc.) of the owner.

Useful tips

The soldering iron tip must be removable. This is what you should pay attention to. The fact is that during operation (especially intensive) its length gradually decreases. Soldering irons with a non-replaceable tip (and there are some of these) are essentially a “disposable” tool.

But this is only one reason for such close attention to this design feature. The second is that in everyday life you have to perform various types of work related to soldering, and there is usually only one corresponding tool at home. Therefore, the ability to change the tip will make solving some problems much easier.

Equipment. It's all about the same sting - there must be another one. The author advises doing the following - the one that was originally installed in the soldering iron does not need to be touched. But it’s advisable to work with a spare.

What to do:

Bend the tip about ⅓ of the length, at an angle of approximately 55 - 65º. This is not difficult to determine visually if you understand why it is being done. The first tip will come in handy if you need to tin something, solder 2 wires, and so on. But the second, curved one, is more convenient for “spot” soldering. For example, fix a thin wire on the contact plate. Anyone who has repaired Christmas tree garlands on their own knows how troublesome this is.

The curved part must be turned into a cone along its entire length. As a result, we get a thin tip of the tip, which is easy to even repair printed circuit boards.

It is advisable to purchase a soldering iron not separately, but complete with a stand. It contains a microswitch that re-switches the circuit. In the working position of the tool, 220 V is supplied to the heating element, and when it is installed on a stand, power is supplied through a diode. This prevents the soldering iron from overheating and extends its service life.

In principle, the information is comprehensive, and it is quite enough to make the optimal choice of soldering iron based on the tasks to be solved at home.

How to choose a soldering iron for the home: types, which one is best for microcircuits, choice of tip

A soldering iron is an indispensable tool for a radio amateur or professional. It is used for soldering wires, parts, microcircuits, etc. The market offers a wide range of products that differ from each other in various parameters. Knowing this, it is important not to make a mistake and choose the best option for your needs that matches the task at hand.

Types of soldering tools

Manufacturers offer various types of soldering irons, the parameters of which depend on the purpose of the tool.

Nichrome electric soldering irons

Such soldering devices are designed for everyday use at home, workshops and other places. The heating element is represented by a wire spiral made of nichrome .

An electric current is passed through it, resulting in heating. In the simplest products, the spiral is wound on a dielectric body, into which a tip (tip) is inserted. The advanced ones already have a thermocouple, and the design is different.

A nichrome electric soldering iron will help you perform minor repairs in electronic and electrical networks.

Ceramic soldering iron

The heating element is a ceramic rod through which an electric current passes. This advanced tool has several advantages:

• fast heating;
• reliability and durability;
• adjustable power and temperature;
• light weight.

The range of application of the device is extensive, the cost is above average.

Ceramic tools are indispensable for soldering, tinning, etc.

Impulse tool

In the Russian version, a pulse soldering iron has a tip made of copper wire - this is a link in an electrical circuit consisting of a transformer and a converter. The tip heats up to operating temperature when you press the device button and then hold it until soldering is completed. Thanks to power and temperature regulators, this soldering iron can solder small and large parts, including microcircuits.

The pulse soldering iron is capable of soldering, assembling and dismantling circuits and networks

Induction soldering iron

The tool consists of the following parts: an inductor and a tip. The tip is heated by an inductor coil. In this product, heating is turned on and off automatically due to the ferromagnetic properties of the tip coating. The battery-powered device is a low-power, self-contained tool used to work with electronic components.

An induction soldering iron differs from conventional ones in its heating principle.

Gas soldering iron

Such a tool refers to devices that can work autonomously in the right place. The tip heats up when the gas burns.

A gas soldering iron is indispensable for working in places where there are no accessible sources of electrical power.

Infrared and hot air soldering stations

This is modern equipment used for soldering complex elements (microcircuits, chip processing and reballing). More often it is used by professionals, less often by amateurs.

The operating principle of infrared soldering is based on heating the part with infrared rays. The concentrated beam of radiation acts selectively, i.e. the desired point is heated, and this avoids overheating of other parts.

Heating occurs using infrared rays

The principle of operation of a hot-air soldering station is comparable to a hair dryer and consists in the fact that a stream of hot air emerging from a focused nozzle treats the required area.

The operating principle of a hot air soldering iron is based on the action of hot air

Special soldering iron

The device is designed to work with plastic pipes, which involves connecting pipes and fittings by heating Teflon nozzles. Teflon nozzles are the best because they evenly heat and melt the plastic.

Using a special soldering iron, you can lay a new or repair an old pipeline

Tools that receive heat from an open flame source

An ancient but still in demand soldering method. A soldering iron heated over an open flame is used for soldering massive metal parts; it is considered an alternative to powerful electric ones.

Soldering irons heated over an open fire are still used today.

Tool selection options

There are no special requirements when choosing a soldering iron. It is important that the device is practical, safe and reliable, has a sufficient range of uses and a long service life.

According to knowledgeable people, despite such a drawback as long heating of the tip, familiar rod tools are better suited for home use.

Before purchasing a tool for everyday household needs, you need to know what it will be used for. The functionality of a soldering iron is determined by its characteristics and parameters. Based on this, the device must meet the following requirements:

1. The dimensions of the product should be minimal for ease of use.
2. The recommended handle material is wood, as it is a good heat insulator.
3. The power of the device is in the range of 25–40 W.
4. Mains voltage 220 V.
5. Soldering irons with temperature control from 150 to 400 degrees are considered in demand.
6. The electrical cable must have reliable and practical insulation.
7. The tip of the required shape (needle, cone, screwdriver) must be made of high-quality material with the possibility of fixation.
8. Flux: rosin (dry or dissolved).
9. The solder should preferably be from a variety of universal low-melting alloys (such as POS).

An important element of a soldering iron is the handle. Manufacturers offer three main materials:

1. Plastic. Handles made from this material are lightweight and low in price. The disadvantage is that they heat up quickly and interfere with further work. Used for work with a short cycle. Despite the significant drawback, tools with a plastic handle are in demand
2. Ebonite. This material has an attractive appearance. It has virtually no flaws, but is heavy and expensive. It can be used for any work with a soldering iron, if the shortcomings do not interfere. Soldering irons with an ebonite handle are of high quality and reliable
3. Tree. This option is optimal for the home, because it is a heat insulator with low weight. The scope of application is not limited. The wooden handle is simple and easy to use

For example, a wooden or plastic handle is suitable for an EPSP soldering iron. But it is advisable to purchase a 60 W soldering iron with an ebonite handle.

For soldering microcircuits, hand-held soldering irons are used together with soldering stations. In this case, the latter must meet a number of requirements:

• the power of the device should not exceed 25 W;
• tip with a diameter of no more than 3 mm;
• It should be possible to adjust the temperature;
• solder is an alloy containing tin.

If you often have to solder parts related to electronics, it is recommended, despite the high price, to purchase a soldering station and desoldering pump.

As a result, when it is difficult to make a choice, it is better to buy an impulse or rod model. Moreover, of these options, the second one is preferable, since it is universal and has the required parameters.

How to choose the right soldering iron for your home

Having a soldering iron in your home allows you to perform many useful operations without going to specialized workshops. It can be used to connect broken wires and cut individual parts from printed circuit boards. If you have the appropriate experience, this simple tool will also allow you to repair any household appliances and electronics yourself.

How to choose a soldering iron for home use? When purchasing a tool, you need to pay attention to a small number of different criteria, so we will talk about them in as much detail as possible.

Gas or electric soldering iron

According to the heating method, all devices are divided into gas and electric. The first type of soldering iron is indispensable for soldering cables in junction boxes, but is not at all suitable for working with radio components. In addition, the device emits toxic substances, which makes it unsafe both for the home craftsman and for others.

For microcircuits and printed circuit boards, electric soldering irons are much better suited, which, in turn, are divided into three main types:

1. Spiral or induction soldering irons, which last much longer than the main ones and easily cope with basic work in everyday life. Their main disadvantage is that it takes a very long time to heat up to the desired temperature.
2. Ceramic devices that heat up almost instantly. They are much more expensive and require very careful handling.
3. Expensive pulse soldering irons. An ideal choice for working with microcircuits and a wide variety of boards.

It is impossible not to mention a special category of devices designed to connect plastic pipes together. They have a completely different design and principle of operation, so we will list their main parameters at the very end of the article.

How to determine the power of a soldering iron

The main criterion for choosing a device is its power. It is this that determines the heating rate of the soldering iron, as well as the scope of its application and can be:

• No more than 10 W. A device with this power is suitable for simple work connecting thin wires and microcircuits.
• 20-40 watts. For home use, this is the best choice, since the device can cope with almost any household operation.
• 60-100 W. This soldering iron is suitable for soldering wires of any thickness.
• More than 100 W. Professional models for specific purposes, which should not be purchased for household use.

Soldering iron functionality

The function of any soldering iron is to heat the parts being connected, as well as melt the solder and rosin. In addition, during the selection process you need to pay attention to a number of additional points, which are listed below:

1. Reliable protection of the handle from overheating. For this purpose, this part is made from materials that do not conduct heat - ebonite, natural wood or special types of plastic.
2. The presence of a thermostat that allows you to conveniently adjust the temperature of the tip to your needs.
3. Electrical safety. To ensure this, manufacturers supply soldering irons with a long and fairly flexible cord with double insulation and a plastic removable plug that does not melt when the load on the network increases. The device is reliably protected from burnout by the function of constantly maintaining the temperature at the desired level.
4. Tip material. You definitely need to choose copper, which is easy to clean from carbon deposits and is light in weight.
5. Equipment. Ideally, in addition to the soldering iron, you will receive a convenient carrying case, a stand for the device, a cleaning device and other components.

For microcircuits and wires, you can purchase a ready-made soldering station, which has a lot of different settings and even the ability to simplify work with electronic parts.

Soldering irons for pipes: features of choice

Above we found out what devices need to be used to connect wires, microcircuits and metal parts. Now let's return to soldering irons for polypropylene pipes. By design, these tools are an electric stove with nozzles, which heat the joints.

Their selection should take into account the following criteria:

• Power. For household use, it can range from 0.8 to 1.2 kilowatts.
• Type of pipeline installation. For coupling, butt and socket joints, different soldering irons are used, which have the corresponding features.
• The diameter of the nozzles, which determines which pipes you can work with.
• Availability of power and heating temperature regulator. These options will greatly simplify the use of soldering equipment.

Finally, you can choose a device with a hydraulic or mechanical drive, which ensures comfortable operation of the device.

Which soldering iron is better to choose for home: rating of good soldering tools

Soldering requires a special tool, which can be classified according to a fairly large number of different characteristics. You should carefully consider which soldering iron is best to choose, since the quality of the work performed largely depends on its performance characteristics. You can purchase tools at the construction market or in specialized stores.

Electric and gas soldering irons

Before purchasing a soldering iron, you should consider purchasing an electric and gas model. The gas version is suitable when work is carried out in the absence of power supply. It has the following features:

1. Butane, propane or isobutane can be used as fuel.
2. The main structural element is a burner, which raises the surface temperature to the desired temperature.
3. Purchased for use in field conditions. The tool is characterized by compact dimensions and low weight.

When choosing a soldering iron for your home, pay attention to electric models. There are self-powered models. Due to the battery used, the tool can last for two hours.

An electric small soldering iron is considered a universal tool, which is characterized by high reliability and safety in use. There are two main types:

To work with a microcircuit, in most cases a pulse device is chosen. This is due to the following qualities:

1. Heats up quickly.
2. The design is easy to use.
3. It has a high rate of efficiency.

When choosing a soldering iron for radio amateurs, many people prefer the pulse version. However, its cost is higher than the rod one.

Rod models are highly practical and reliable in use. This option is considered universal, but the disadvantage is the long warm-up period.

Popular brands

Good tools are produced exclusively by well-known manufacturers. The most valued devices are those produced by Japanese and German companies:

1. Goot.
2. Hakko.
3. Weller.
4. Matrix.
5. Ersa.

Tools from these manufacturers are used by professionals. They can be used for the painstaking work of soldering SMD components. High build quality ensures long-term operation of the tool. As a rule, China provides more affordable equipment.

Design and operating principle

The choice of tool should be made taking into account its structural tools. Main elements of a soldering iron:

1. The tip is a metal rod that is heated to the required temperature.
2. Heater - an element due to which the main element is heated.
3. Holder - used to secure the tool during operation.
4. Electrical cord with plug - used to connect the device to the electrical network.

After connecting the tool to the power supply network, the rod is heated, which is made using a material with high thermal conductivity. The tip is heated to a temperature of 450 degrees Celsius, after which it melts the solder used. A certain alloy in a liquid state flows into the gaps of parts, after solidification it forms a high-quality permanent connection with the required performance properties.

Types of electric soldering irons

The main classification is related to the design features and heating principle of the device. Based on these characteristics, the following classification is carried out:

1. Nichrome soldering iron.
2. Ceramic model.
3. Pulse soldering iron.
4. Induction model.
5. Wireless version.
6. Portable USB soldering iron.

Each type of tool has its own characteristics. indicates that impulse models are more popular.

Features of a nichrome tool

An electric soldering iron with a spiral heater is represented by a combination of turns of nichrome wire. A rod is placed inside the coils, which heats up during operation. Mica tubes or plates, as well as fiberglass fabric are used as insulating materials. The advantages of this tool include the following aspects:

1. Low cost offer.
2. The design is unpretentious in operation and does not respond to mechanical damage and shock.
3. The tool is suitable for repair.

There are also quite a lot of disadvantages:

1. It takes quite a long time to heat up.
2. Almost all models are not designed for long-term use. In addition, with regular use, the spiral used quickly burns out.

Many people choose this type of tool because of its affordability.

Ceramic models

Ceramics are known for their high wear resistance and the fact that they can withstand high temperatures. That is why the material is used in the manufacture of soldering irons. It is worth considering that this type of tool is produced by only a small number of manufacturers. In most cases, a nichrome soldering iron, which has ceramic insulation, is disguised as a ceramic soldering iron.

The advantages of such models include:

1. Fast heating. Ceramics have high thermal conductivity, which reduces heating time.
2. Many models have a control system that maintains the set temperature over a long period.
3. Despite the small size of the device, it has high power.
4. Long service life.
5. The tip and other elements withstand intense loads and are not subject to overheating.

The ceramic option has quite a few disadvantages. This is why the tool is produced by a relatively small number of companies. We include:

1. Very high cost, which is associated with the use of expensive materials and complexity in manufacturing.
2. There are simply a huge number of fakes on sale.
3. The fragility of ceramics means that the instrument should be handled with care. Dropping the soldering iron from a height or impact may cause a crack to appear on the ceramic part.

Today, ceramic models are extremely rarely used. This is due to the fact that there are modern devices that are characterized by higher performance.

Pulse Soldering Tools

Impulse models have become quite widespread. They differ in that heating occurs exclusively when the start button is pressed. This type of tool is suitable for short-term work.

The design features of such a tool include the following points:

1. Main elements: frequency converter, high-frequency transformer, control chip.
2. The sting is made of copper. To heat it, a low voltage current is supplied.

The advantages of the proposal under consideration include:

1. It takes less time to heat up the tip.
2. The tool can be used to work with small and large parts.
3. High efficiency. Heating only at the time of soldering significantly reduces costs.

The disadvantage is that the tool is not suitable for long-term work.

Induction soldering irons

Recently, induction soldering irons have become widespread. They work according to the following principle:

1. A high-frequency magnetic field is applied to the rod. To generate it, an induction coil is installed.
2. Inside the rod there is a core made of a special alloy. It is he who transfers heat to the sting.
3. The temperature at the tip can be maintained for a long period.

The advantages are the following:

1. High cost efficiency. Only the surface layer is heated, and not the entire tip.
2. The required temperature is automatically maintained.
3. If necessary, you can quickly change the tip.
4. The surface of the tip heats up evenly.

The disadvantages of this device are the high cost and complexity of using the equipment.

You can also note the possibility of choosing a cordless soldering iron. It is suitable for work in the field. Batteries or one large battery can be used as a power source. To ensure long-term operation, the device must have a high efficiency rate. The disadvantage is the low power, since only in this case the device can last a long time.

Nichrome soldering iron

It is also called an electric soldering iron with a spiral heater, or ESP. The heating element of this tool is a spiral of thin nichrome wire through which an electric current passes . More modern models have a nichrome element built into the insulators.

Advantages:

• average price, availability;
• Impact resistance, the soldering iron is not sensitive to mechanical damage.

Flaws:

• sensitivity to stress; with intensive daily use, its coil burns out;
• The tip takes a long time to warm up.

Hammer soldering iron

Modern models are electric or heated from external heat sources (from an open fire). The name “hammer” comes from the design - a handle with a thick tip . The device allows you to solder large parts.

Advantages:

• low price;
• the ability to make such a soldering iron manually;
• good power (from 100 to 150 watts).

Flaws:

• little functionality;
• inability to regulate heating temperature.

 Pulse soldering iron

Soldering irons of this type do not have constant heating, and the tip heats up when the button is pressed. For convenience, this device has a curved shape . Long-term soldering is not provided in this case, but it is convenient to use a pulse soldering iron for short-term work.

The tip is made of copper wire and is heated by electric current. Modern companies produce pulse instruments with removable tips and a ceramic heater.

The new type of devices have additional functions, such as power and temperature control, which makes it possible to solder both small and large parts.

Advantages:

• rapid heating of the tip;
• soldering parts of different sizes;
• high efficiency (heating of the tip directly during soldering).

Flaws:

• can only be used for short-term work.

Wireless soldering irons

The power of this type of device is relatively small; the soldering iron does not operate on mains power, but on batteries, and is used in cases where there is no electricity or the need to work in special conditions.

Advantages:

• fast heating;
• mobility and no need for a power supply network;
• small size.

Flaws:

Portable USB soldering irons

These are small-sized soldering irons with USB power. This device can be powered by a car cigarette lighter and is designed for soldering small parts.

Advantages:

• mobility;
• small size;
• heats up quickly.

Flaws:

Soldering iron with tin suction

This is a rather original and convenient device that is easy to use. It is best to choose a soldering iron with an insulated handle; it will ensure safety during operation and will last longer . Low-quality soldering irons with built-in solder suction are characterized by rapid failure.

Soldering iron for children

This is a device with low power - from 30 to 60 watts. There are electric, pulse and battery-powered . It is recommended to purchase a tool with a wooden handle.

Tip Types

Soldering iron tips have several varieties and are made of ceramic, copper, and can also have a silver, aluminum, or nickel coating.

copper sting

Such tips are installed in electric soldering irons.

Advantages:

• good thermal conductivity;
• heat capacity.

Flaws:

• oxidation of the rod and, as a result, a decrease in its functionality;
• such a tip has to be cleaned, it becomes thinner and soon needs to be replaced.

Nickel plated tip

This tip is also included in the design of electric soldering irons and devices with a ceramic heater.

Advantages:

• does not burn during operation;
• there is no need to regularly clean it.

Flaws:

• high price;
• fragility of the material.

Ceramic tip

Its body is made of ceramic, and the tip is usually copper, plated with nickel.

Advantages:

• thermal conductivity;
• corrosion resistance;
• no need for constant cleaning.

Flaws:

• high price;
• fragility of the ceramic case.

Shape of the tip

The shape of the tip depends on the type of work being done. However, some designs of soldering irons do not imply the use of replaceable tips, and in this case, replacing the tip becomes difficult and time-consuming . In addition, there are soldering irons with adjustable tip length.

The stings come in the form of a wedge (screwdriver), a rod with a beveled edge, cone-shaped, or needle-shaped. The most convenient, universal shape is the shape of a screwdriver, as it is suitable for performing various jobs . This shape allows you to quickly heat the required part, and the solder on this tip holds better than on tips of other shapes.

Soldering iron handle material

The soldering iron handle should be made of materials with low thermal conductivity. It can be a wooden handle, ebonite, as well as a handle made of carbolite and textolite . Plastic handles are found on the cheapest models; they heat up quickly and can melt. The best choice would be a wooden handle, as it has the lowest thermal conductivity.

How to choose the right soldering iron

When choosing a soldering iron, you should be guided by basic criteria, such as its power, thermal stabilization and, of course, the price of the device.

Power

This indicator depends on the type of work. A power of up to 25 watts is suitable for soldering small electronic parts, a power of 40 watts is suitable for working with thick wires . Higher power, from 100 watts and above, is suitable for soldering large parts . The advantages of high-power soldering irons are their reliability and a wide range of functions, but their disadvantage is that such devices are not used in everyday life.

The power of a home soldering iron should be from 25 to 40 watts. A lower power rating will mean that soldering will take a long time, and the quality of the result will be questionable . Excessive power will make it impossible to solder parts that could simply burn out.

Thermal stabilization

Soldering irons with thermal stabilization significantly speed up the soldering process, improve its quality, and it becomes much more convenient to work, as they provide the opportunity not only to accurately set the temperature required for work, but also to maintain it. This is convenient for both beginners and professionals . The temperature regulator can be either in a separate case or built into the design of the soldering iron.

Advantages:

• automatic maintenance of the desired temperature;
• the danger of overheating is eliminated;
• With one soldering iron you can perform work that requires varying degrees of heating;
• there is no need to clean the soldering iron tip from scale.

Flaws:

• the original tip is not universal;
• fakes are common;
• takes a long time to heat up.

Soldering iron cost

Prices directly depend on the characteristics and functionality, type of heater, the presence or absence of a temperature controller, and the brand that produces the device. You can buy an inexpensive soldering iron that has good characteristics and is suitable for home work, or you can choose a more expensive model with additional functions.

Inexpensive and budget soldering irons include devices costing from 80 to 600 rubles. Most often these are electric soldering irons with a copper tip and a power of 40 watts. This also includes ceramic soldering irons with a nichrome heater, a nickel tip and a power of 30 to 40 watts - their cost ranges from 300 to 600 rubles.

Medium-priced soldering irons are pulsed, with a power of 70 watts (from 300 to 700 rubles), wireless and USB soldering irons, with a low power of up to 10 watts (from 300 to 2019 rubles).

A soldering iron with a durable tip and a film-ceramic heater with a power of 50 watts costs from 2019 to 2019 rubles.

How to choose a soldering iron

July 5, 2018

A soldering iron can be selected according to the following criteria:

• Functional purpose.
• Type of heating element.
• Power.
• Type of electrical connector.
• Material for making the heating element.
• Handle shape.
• Possibility of temperature control.

Let's take a closer look at each criterion.

What you need to know about the functional purpose of soldering irons

Based on this feature, all soldering irons are combined into two large groups: soldering irons for plastic pipes and soldering irons for metal, such as electrical wires and microcircuits.

Soldering irons for plastic or propylene pipes are also called pipe welding machines. And in the professional slang of installers, this tool is called an “iron.” Soldering irons of this type are suitable for connecting water pipes of different diameters.

Soldering iron for polypropylene pipes

When choosing a soldering iron, pay attention to the following characteristics:

• Power. For soldering small-diameter pipes, as well as for domestic use, a tool with a power of 1 kW is sufficient. If you work with pipes with a diameter of 25 mm or more or use a soldering iron constantly, choose a tool with a power of 2 kW.
• Set of nozzles. Choose a soldering iron with a full set of attachments. This will allow you to work with pipes of different diameters.
• Nozzle coating . The preferred option is steel nozzles with a Teflon non-stick coating. Uncoated steel attachments have melted plastic that sticks to them and is difficult to clean off.

Soldering irons for metal are used to solve various problems: from soldering wires and microcircuits to tinning car radiators, metal containers and other parts and objects. Use the criteria below to select this tool.

Soldering iron with what type of heating element do you need?

Based on the type of heating element, soldering irons are divided into two groups: gas and electric.

Gas soldering irons operate on butane. Lighters are refilled with the same gas. Choose a tool of this type if you often solder in places where there is no way to connect to electricity.

Gas soldering irons are portable and lightweight. They can also be used as a heat shrink hair dryer and a small gas torch.

A gas soldering iron is not suitable for constant use indoors, as it emits harmful substances during operation. In addition, in workshops or at home it is cheaper to use an electric soldering iron, which does not require refilling with gas.

Portable gas soldering iron

What does the power of an electric soldering iron indicate?

The power of a soldering iron determines its functional purpose. Everything is extremely simple here:

• Soldering irons with a power of up to 30 W are used in everyday life for soldering wires. They are also suitable for radio amateurs.
• Soldering irons with power up to 60 W are designed for professional installers who constantly work with wires and cables of different diameters.
• Soldering irons with a power of 60 W or more are chosen by auto repairmen. This tool is suitable for tinning large metal products.

There is a pattern: the more powerful the soldering iron, the larger and heavier it is. With power, the size of the tip, that is, the working tip, also increases.

Why is the type of electrical connector important?

Electric soldering irons accumulate static electricity. Electrostatic discharge can damage microcircuits and other radio components. Therefore, radio amateurs need to choose a soldering iron that has an electrical plug with grounding. In everyday life, such forks are often called “Euro forks”. If you do not solder radio components, skip this step.

Grounding Plug

What material should the heating element be made of?

The most commonly sold soldering irons are those with a copper tip, those with a copper tip with a nickel-chrome coating and a ceramic heating element.

Do not buy soldering irons with a copper tip. This type of heating element burns out quickly. In addition, solder and other impurities stick to the copper tip. Cleaning the tip while soldering is inconvenient.

Prefer soldering irons with a nickel-chrome coating on the heating element. It is also called nichrome sting. Nickel-chrome coating increases tip life and prevents solder sticking.

Soldering irons with ceramic heating elements heat up and cool down quickly, since ceramics have high heat transfer. This is the main advantage of ceramic soldering irons. That is, a tool of this type is suitable for craftsmen who often turn the soldering iron on and off and perform single soldering.

A ceramic soldering iron has a drawback: the fragility of the heating element. If such a tool is dropped, it may fail.

For routine soldering, such as soldering wires or chips in a workshop, a nichrome soldering iron is suitable. If you often perform single solderings and constantly turn your soldering iron on and off, buy a tool with a ceramic heating element.

What do a soldering iron and a gun have in common?

Professional fitters and auto mechanics prefer soldering irons with pistol-grip-shaped handles. Such a tool is more convenient to hold in your hands if you have to solder constantly. Also, the pistol grip is more convenient if you need to work with powerful and heavy soldering irons.

If you solder occasionally, a tool with a regular handle will do.

Soldering iron with pistol grip is comfortable to hold in your hands

Why adjust the temperature

The temperature controller increases the versatility of the tool. With the same soldering iron you can solder small microcircuits and large diameter wires.

A simple microcircuit is used to regulate the heating temperature, so the regulator practically does not reduce the reliability of the tool. But a soldering iron with a temperature controller costs a little more than a tool without heat control. Therefore, start from your work tasks. If you are doing the same type of soldering, you can get by with a regular soldering iron. If you solder different parts - from microcircuits to cables, pay attention to soldering irons with regulators.

Soldering iron with temperature controller

Which sting shape is better?

Most often, there are tips of two forms: a tip sharpened on both sides at an angle of 45° and a beveled tip. All other forms are variations of the basic types.

The first option is considered universal and is suitable for most jobs. A beveled tip is used for very delicate work, such as soldering microcircuits.

The tip of any shape can be straight or curved. This does not affect performance, but it does affect the way you grip the soldering iron.

If you solder small parts, purchase a soldering iron with a beveled tip or a needle tip. For other tasks, a spatula with double-sided sharpening is suitable. Universal option: soldering iron with a set of replaceable tips.

Replacement soldering iron tips

Conclusion

Choose a soldering iron depending on your needs. For soldering polypropylene pipes, a 2 kW tool with a set of Teflon-coated nozzles is suitable. For household use, you can purchase any soldering iron with a power of up to 30 W.

To solder radiators and large metal parts, you will need a soldering iron with a power of 60 to 100 W. Nichrome soldering irons are considered the most durable. When choosing, pay attention to the shape of the handle, the presence of a temperature regulator and a set of replaceable tips.

How to choose a good soldering iron for soldering

In continuation of the series of topics on choosing a tool for the home, let's talk about how to choose a soldering iron. Naturally, the process must be approached with the utmost seriousness in order to select a truly high-quality tool suitable for soldering microcircuits or radio components.

So, choosing a soldering iron involves paying attention to the points that will be of interest to us:

• Size and power rating;
• Operating voltage;
• Type of heating element;
• Thermal insulation of the handle from the heater;
• The presence of adjustment of the length of the tip.

Size and power rating

Dimensions most often depend on its rated power. However, as with all rules, there are exceptions. Usually, you don't need a very large tool to solder chips. The optimal sizes will be the following:

• The length from the point of wire entry into the handle to the tip is 25 cm;
• The diameter of the tip is no more than 4 mm. This relates to the question of which sting to choose.
• The rated power of the soldering iron is up to 25 W.

Choosing a soldering iron will allow you to conveniently solder both microcircuits and various other parts. However, if you often do soldering, then it is advisable to have a larger device, with a power of 40-60 W. With its help, you can solder bulk contacts, tin various elements, etc.

Operating voltage

To choose the right soldering iron for your home, you need to understand the following. The supply voltage of the tool has no dependence on its power. Based on the supply voltage, you can choose the following tools: 6, 12, 36, 220 Volts. Accordingly, a device for radio amateurs, designed for a voltage of 220 Volts, is powered directly from a household outlet.

To work with a tool of a different voltage level, you will need a step-down transformer . It is precisely because of this inconvenience that most people prefer a 220 V electric soldering iron. However, it may have the following malfunction: the internal wire may accidentally short-circuit to the body of the device.

In this case, you may receive an electric shock or, if you are soldering a delicate part at this moment, damage it.

It also happens that the soldering iron tip is placed in such a way that it melts its wire. As a result, you will also get unpleasant consequences in the form of disconnecting the switching devices at the input (machine or traffic jams).

Choosing a soldering iron using a step-down transformer also has its advantages. We can say that individual microcircuits or transistors are afraid of static electricity, as a result of which it is necessary to ground the device body.

Such a transformer can now be easily purchased in a store or made on your own. Here to whom is what is closer.

The only thing that needs to be remembered when choosing is that its power must be no less than the rated power of the soldering device.

Heating element type

We continue to study the question of how to choose the right soldering iron. There are several types of devices. The most popular is an electric soldering iron for microcircuits with a spiral heater (EPSN) . In such a device, the heating element is a ceramic tube on which nichrome wire is spirally wound. From practice we can say that if you choose this type, you will get the most durable and reliable device.

As an example, let's give another fairly popular type of soldering iron for the home - with a ceramic heater. Again, from work experience we can say that they are quite capricious devices. The problems are explained by the design of the heating element: the ceramic plate in which the spiral is located is made of extremely thin wire.

If it happens that during operation any liquid gets on the heating element, it will crack, the inner wire will break, and the tool will stop working. A similar fate awaits the device if it falls unsuccessfully and becomes deformed. Another argument against this type will be the price - it is up to 2 times more expensive than EPSN.

Therefore, there will be a good soldering iron for everyone.

Thermal insulation of the handle from the heater

To ensure that you don’t burn your hands while working, during the selection process you need to evaluate the insulation of the handle from the heating part of the device. Particular attention should be paid to this point when you need to choose a soldering iron for your home with a wooden handle.

Most often, to prevent heat transfer to the handle from the heating part, holes are drilled on it. This is done in order to reduce the total area of ​​the metal surface capable of heating, and besides, it promotes better cooling through heat exchange with air. Accordingly, the greater the number of holes on the metal case, the better the heat will be dissipated.

It happens that the holes are not made, but this requires a long metal case that can quickly dissipate heat.

Another solution for heat protection of the handle is an apron, which is an extension of the handle. With its help, it is possible to lengthen the body of the device, but without adding length to the entire instrument, that is, the body partially extends into the handle. Therefore, when you decide which soldering iron to buy for electronics, pay attention to the presence of this element.

Availability of tip length adjustment

When people study which soldering iron is best to choose, they often pay attention to the presence of tip adjustment. Tin-lead solder, which is the most common solder used in soldering, reduces the tip over time . As a result, we have dimples, notches, and shells on the tip.

Their presence greatly interferes with the soldering process, but they can be removed quite easily - by processing with a file. However, this method of eliminating notches has its drawback - with constant processing, the sting will decrease in length.

Of course, if you solder from time to time, this point will not be too relevant for you, but if you are a regular user of this tool, then the problem may be acute and then you need to choose the appropriate soldering iron. However, this feature is not the worst.

The thing is that the process of solder eating the tip occurs the faster the higher the temperature. That is, the shorter the length of the tip, the higher the temperature at the end of the working part will be, and the faster the process of devouring the tip will occur.

What to do? It is necessary to stabilize the length of the tip, that is, after filing, the working part should be slightly lengthened, moving it out of the body. However, you will not be able to do this procedure with all devices. Therefore, when choosing, pay attention to the presence of this feature.

Let's hope that now the question of how to choose a soldering iron for soldering will not be relevant for you and you will figure out the choice without any problems.
