How to make magnetic mass for a welding machine at home?

Magnetic mass for welding is a special device that provides reliable fixation on metal surfaces. This allows you to comfortably perform welding work on complex surfaces where the use of classic alligator clips is impossible.

There are many design options that depend on the work conditions. The structure of this device is not particularly complicated. For this reason, some craftsmen prefer to use homemade magnets for welding.

What's happened?

This device is mounted on the working plane of the workpiece . Thanks to the active magnetic field, a strong fastening is achieved, creating a closed electrical circuit - the main condition for the formation of an electric welding arc.

The tool is especially popular among novice welders - it will take a few minutes to familiarize yourself with the principles of the work. Experienced specialists use magnetic mass for welding machines for critical work - welding large-diameter pipes or connecting load-bearing units made of profile materials.

Design of magnetic contact and its characteristics

Consists of two nodes:

1. Cable holder . The ground cable of the welding equipment is attached to it using a bolted connection.
2. Magnetic node . The size of the magnet depends on the design features. Some models are equipped with a mechanism that regulates the pressure of the magnet on the working plane. Professional devices have switches.

The parts are connected to each other by a rigid fastening. The main characteristics of the devices are:

1. Dimensions and weight. Depends on the manufacturer and specific model. The average weight is 1-1.2 kg.
2. The force of attraction to the surface. Varies in the range from 2 to 50 kg.
3. Welding current strength. The maximum value of the parameter is measured in amperes. For entry-level models, it does not exceed 200 A. An advanced tool is capable of operating at 400-500 A.
4. Execution type. They produce special clamps for corners with gap adjustment.

Advantages and disadvantages

Electric welding is the most common method of joining metal products. The quality of the future connection depends on the integrity of the electrical circuit .

That is why the invention of the device in question aroused serious interest among specialists.

The popularity of magnetic mass for welding is due to the following advantages:

1. Reliable fixation will allow the welder to concentrate on work without being distracted by adjusting the clamp.
2. The working mechanism is a permanent or switchable magnet. Subject to compliance with operating conditions, it can serve for an unlimited period.
3. You do not need any consumables to use the holder.
4. Even compact models have a contact patch sufficient for reliable closure.
5. The device is resistant to sudden voltage changes or temperature changes.
6. The magnet can be attached to any place to create comfortable conditions for making the connection.

Despite the large number of advantages, there are a number of disadvantages:

1. Before use, it is necessary to prepare the surface. The procedure involves removing dirt and foreign particles.
2. There is no possibility of attaching to small parts, for example, a circle with a small cross-section.
3. It is impossible to work with non-ferrous metals because they are not magnetic.

How to use?

The technology for using the device is not complicated. First of all, the welding cable is connected, after which installation begins .

Most units are equipped with switches that activate a magnetic field. At rest, the magnet will not be attracted to the surface.

One person is required for commissioning. After contact with the working plane, the device must be activated. Upon completion of these steps, the clamp is in operating mode.

After completing the work, perform the above steps in reverse order. Do not try to separate the switched-on device from the part - many models have quite high tear strength. In addition, this may damage the latch.

Is it worth buying?

The answer to this question can only be given by the master performing the work. For a novice welder who has just started his professional career, this device can make life significantly easier.

If a specialist works primarily with non-ferrous metals, a magnetic clamp will most likely not be useful.

Experienced workers have a set of various clamps for all occasions, including this device.

The cost of the device is quite high. If you have knowledge in the field of electrical engineering, you can try to make it yourself. The technology and manufacturing process will be discussed below.

How to do it yourself?

Experienced craftsmen try to reduce all costs for the purchase of auxiliary and working equipment to a minimum. Due to the simplicity of the design, no special equipment or complex tools are needed for manufacturing .

To assemble a homemade device, you should prepare the following equipment:

1. Magnet . The working part of the unit. It must have sufficient power to securely attach to metal. Magnets from old car speakers with a power of 10-15 W are ideal for this purpose.
2. Two washers . Their size must correspond to the diameter of the magnet.

1. A set of hardware for fixing the welding cable.

Algorithm for performing the work:

1. One of the washers will make contact with the working plane. It is necessary to make a hole in it corresponding to the size of the bolt head.
2. The cap is cut to the thickness of the washer.
3. After preliminary preparation, the structure is connected by welding. The product should resemble a mushroom, in which the threaded part of the bolt plays the role of a leg.
4. A magnet is placed on the mushroom. Place a second washer on the reverse side.
5. A welding tip is attached to the thread, and the entire structure is secured with nuts.

Functionality testing is performed only in the field. The quality criterion will be the correct functioning of the welding machine.

Do-it-yourself welding machine compound is a great way to save money, as well as a means to test your DIY construction skills.

A properly assembled device will last no less than the factory clamp.

Magnetic mass for welding: what is it, where is it used and how to use it correctly

In the work of a welder, devices such as a magnetized contact or a magnetic-based terminal are often used. They greatly simplify the preparatory work.

The magnetic mass is attached to the iron structure and held there. Therefore, you can immediately begin welding work.

In this publication we will try to answer all the questions that arise in the process of using magnetic grounding terminals. Is it worth using it and where is the best place to buy it? You can read about all this in this article.

Introduction

First, let’s define what a magnetic welding cable contact is. This is a kind of auxiliary device.

It is attached to the required area of ​​metal to be joined, based on its magnetizing properties. This contributes to the formation of a closed electrical circuit, without which manual electric arc welding cannot be performed.

Magnetic welding clamps are used by welders with any experience. Some craftsmen make a special magnetic mass with their own hands. For more details, see our video at the end of the article.

Advantages

Magnetic mass has many advantages. It can quickly be attached to any surface, even curved.

Its design is very simple. It does not deform, so it can be used for years without losing its properties. After all, in essence it is a simple magnet that works thanks to its magnetic field.

Such a terminal does not contain any other devices or parts, and therefore cannot break.

Changes in temperature conditions and voltage surges do not negatively affect the functioning of magnetic clamps. They rarely burn out and can be used in combination with different metals.

They will be especially convenient for cooking in hard-to-reach places or on curved surfaces. The magnetized mass provides a tight fit due to its coverage of a wide surface area.

For welding, in addition to working tools, protective devices for the face and hands of the welder, additional devices are also used - they will facilitate the work and allow it to be done accurately and accurately.

Magnetic angles - pure welding gadgets

Any device that simplifies the work has its advantages.

Magnetic holders for welding are a convenient attribute. You can either buy them in a store (for example, in the World of Magnets) or make them yourself.

Warning: the use of homemade, uncertified devices is hazardous to health and may result in defects in manufactured products.

This attribute is useful even when performing simple one-time work; it will facilitate welding of products because:

• Due to the fact that the metal elements are fixed, it is convenient for the welder to work and he gets freedom of action;
• The assembly of a welded structure begins before welding with the fixation of elements, so one person can weld the product - magnetic devices for welding work reduce labor costs;
• Parts secured with welding magnets stand straight and will not move, for this reason a neat weld is obtained:
• When assembling high-precision products, magnets for welding are not only convenient, but necessary;
• With a large number of welding jobs, they reduce the time spent on welding;
• Non-standard parts are securely fastened without additional devices;
• The parts are installed using welding magnets, both horizontally and vertically.

Magnets from well-known manufacturers have a shape that allows you to set angles of 45°, 60°, 90°, 135°, for reliable fastening of parts. A self-made magnet sometimes fell off, but a factory-made product makes it possible to do work at any angle without moving the part.

Types of magnetic holders for welding

For welding metal structures, different magnets are used; they differ in shape and operating principle:

• Simple magnetic corners allow you to install parts at the required angle;
• A magnetic clamp makes it possible to weld structures of any precision and complexity, placing the welded elements at any angle;
• The magnetic clamp is equipped with a switchable or permanent magnet - this allows you to turn off the magnet after welding and remove the clamp without effort;
• Most angles can be installed at different angles - the design allows for welding of varying complexity;
• Different models of angles have different power - for fixing parts with a large mass, and for welding large structures, high-power magnets are required, but for household work and welding small products, low-power welding magnets are needed.

To get good results when welding complex products, you need to simultaneously use different magnetic devices.

Here are the 7 most common:

Magnetic devices. Externally – 2 metal plates connected together, with a magnet installed between them. Angles can be changed or fixed in one position.

Switchable magnets. Allows you to install the parts to be connected by turning on the magnetic field. At the end of welding, it is turned off and removed in one motion. It is easy to remove metal shavings from such a magnet.

Installation magnets. Used to place parts of the structure to be welded in the required position. They may have the ability to turn off, which reduces the impact of the magnetic field and allows you to effortlessly move the device to another location.

Angular constant action

A magnet for welding parts at an angle is a popular device; it is characterized by its low cost and simplicity of design. This device is used to secure metal elements in the desired position when welding various structures.

• It allows you to quickly and reliably assemble parts of the product, and will help when working with steel pipes, profiles and angles, and sheet metal.
• There are 3 types of magnetic corner for welding:

• Hexagonal;
• Triangular;
• Arrow-shaped.

The hexagonal fixture can be installed at angles in:

1. 30 degrees;
2. 60 degrees;
3. 75 degrees.

Triangular and arrow-shaped devices can be installed at angles in:

1. 45 degrees;
2. 90 degrees;
3. 135 degrees.

These devices facilitate the assembly and welding of products and reduce working time. The downside is that the magnet strength is low, for models in the low price category.

Disabled and enabled

1. * switchable magnetic angle for welding structures
2. * includes for welder (switchable, magnet)
3. The use of switchable and switchable magnets makes it possible to reduce and simplify the installation of metal structures.

   They have advantages over permanent magnets:

• Easy to clean the switched-off magnet from small metal;
• Possibility of adjusting the location of parts to be welded when the magnet is turned off;
• Reliable fixation of structural elements when the magnet is turned on in a certain place.

The advantage of such a device is that it is easy to remove after tack work, with just one movement. Magnetic corners can be template or universal. Standard products are made with fixed angles, and universal devices make it possible to weld 2 parts of the structure at any required angle.

Attention! The design sometimes includes a V-shaped groove. It includes the ability for the welder to fix even very small metal parts of any complexity.

Advantages of working with a magnetic square

Inexpensive standard products are suitable for amateur work, but for professional welding you need complex tetrahedral and three-coordinate devices - made of heat-resistant magnets.

A high-quality magnetic holder designed for welding metal structures is tensile strength, can withstand heavy loads, and is resistant to mechanical stress.

A magnetic square that has the required power must reliably hold the parts of the structure to be welded - this will make independent work easier and safer.

Recommendation! To make it easier to remove the magnetic device, it is advisable to use switchable magnetic holders.

It is necessary to select a magnetic holder suitable for the job, taking into account the expected angles of the structure, the weight of the tool used, and the power of the magnet.

What to look for when choosing 

For a professional welder, it is important to choose the right magnets for welding metal products. This will allow you to do the job efficiently without an assistant.

When choosing, you need to remember:

1. 1. Low power welding magnets should not be used when welding heavy structures. Under heavy weight, a weak holder will not be able to fix massive parts. But a device that is too powerful will complicate the work due to its size and large mass. You need a neodymium or regular magnet suitable for a specific task;
   2. Triangular devices are most often used. They can be installed at angles of 45, 90 and 135 degrees;
   3. It is more convenient to use switchable devices. 

Welding work is carried out at a distance from the magnetic device. If it heats up, the qualities of the magnet will disappear. Strong blows also harm him. There are no more restrictions when using magnetic welding devices.

A simple DIY magnetic square

You can make your own simple magnetic welding square from the speaker on your TV. The product will look like this.

Any grade of steel is suitable for the job. The plates for the product are cut out of sheet metal manually, or a grinder is used for the work. The most important thing is to cut the corners of the fixture accurately.

After this, an insert is made that is installed between the 2 plates; it is needed to increase the rigidity of the product and to protect the magnet from metal filings. Any material will do; for example, you can use plywood, from which a triangle blank with a hole is cut out. The insert is made a few millimeters smaller than the plates; this is necessary so that the insert does not interfere during operation.

After this, the elements of the welding angle are assembled together, and, after lubricating the parts with glue, they are secured with aluminum rivets. DIY welding holder plates must be installed parallel to each other.  

• After the glue has hardened, you need to cover the magnetic corner with a primer and paint it in a suitable color.

As a result, you will get a welding angle, similar in its characteristics to the branded magnetic angle. It is important not to heat the magnet during operation, otherwise the high temperature will cause loss of magnetic qualities.

How to use magnetic mass? And is it worth buying it?

Reading time: 2 minutes

Magnetic terminal, magnet clamp, magnetic contact of welding cable This device has many names. But the essence is always the same: a magnet allows you to quickly and reliably attach it to the ground and start welding.

But what is it? What are the pros and cons of a magnetic ground terminal? How to use it and is it worth buying at all? You will find the answer to these and some other questions in our article.

What it is?

The magnetic contact of a welding cable is a device that is mounted on the surface to be welded (ground) using an active magnetic field. The device is necessary to form a closed electrical circuit. Without this, manual arc welding is impossible.

The magnetic ground clamp is very popular among both beginners and professional welders. Magnetic mass is also often used for DIY welding at home. It quickly and securely attaches to any surface, even curved ones.

Magnetic mass for welding - Metals and their processing

page » Articles about welding » Welding station » Equipment » Ground clamp

The list of basic devices required for manual electric arc welding includes the following items: electrode holder; welding cable to holder; return cable; ground terminal (ground clamp).

Quite often these components are not of high quality and require immediate replacement. There are times when the contractor will need a replacement after a short period of use.

Important! If the welding work clamp is faulty, this negatively affects the work process, its productivity, and most importantly, safety for the welder, the stability of the arc, and the quality of the connection.

The choice of any technical device or device requires a careful and attentive approach. A correctly selected ground terminal can protect the performer from electric shock and will guarantee a high-quality and reliable connection. To select the optimal welding work clamp, you should pay attention to the following important aspects .

1. You need to choose well-known and trusted brands , which will help you avoid purchasing counterfeit products. It is very difficult for a person who does not have sufficient experience to distinguish a fake from an original product. Therefore, you need to buy products only from specialized sellers and suppliers.
2. The ground clamp for the welding machine should be selected taking into account the maximum current that the unit produces.
3. Also, the clamp must confidently withstand the weight of the connected cable .
4. a spring acts as a compression mechanism , then its properties should be sufficient for reliable contact with the workpiece.
5. One of the main roles is played by the opening angle of the terminal, the value of which should be sufficient for reliable fastening to parts of various sizes.

Types of ground clamps

Ground clamps for welding machines, depending on the nature of the fixation, can be of several types. Next, we will look at the main types of clamps, as well as their advantages and disadvantages.

crocodile clip (“clothespin”) for grounding , which is attached directly to the part.

Advantages:

• reliability of connection with the surface of the part;
• convenience and speed of use;
• minimum connection resistance;
• the ability to fix parts of various geometric shapes, including those with complex configurations;
• high degree of disclosure.

disadvantages should also be highlighted :

• low, compared to other types, level of strength of some components - spring;
• This type of clamp is used only in cases where it is possible to attach directly to the product.

The alligator clip should be selected based on general recommendations. Terminals of this type are available in three main modifications: ground clamp 300A, 200A and 500A. Depending on the model of the welding machine and the current it produces, you need to determine the optimal modification. To carry out work at a professional level, it is recommended to purchase a 400-500A clamp.

Important! It should be noted that the use of a clothespin clamp when welding large diameter pipes is impossible.

We recommend looking at tips on how to extend the life of the clothespin that came with the device and what to consider when buying a new one.

2. Magnetic mass for welding

Welders quite often use a magnetic ground clamp . This type has a whole range of advantages :

• the ability to attach the contact to any surface or structure, including pipes;
• simplicity of design ensures durability and trouble-free operation;
• the absence of springs and other mechanisms also contributes to long service life;
• a ground magnet for welding is able to withstand voltage surges and not burn out;
• successfully used in hard-to-reach places;
• The large contact area guarantees secure fastening.

Flaws:

• unreliable fastening of the contact to small-area parts , for example, fittings;
• impossibility of securing the clamp to products made of non-ferrous metals;
• the magnet must be periodically cleaned of contaminants , in particular metal shavings;
• Avoid overheating the magnet, otherwise it may demagnetize ; Overheating occurs if the terminal is attached to a dirty surface.

3. Clamp

Clamp -type welding clamps are used less frequently than the two types listed above. This type of terminals also has several advantages :

• high degree of fastening reliability, since fixation is carried out using a hex head screw;
• good contact with the workpiece ensures a smooth transition of current.

The disadvantages include the rather complex structure of the mechanism and the relatively large dimensions of the terminal.

4. Centralizer

In rare cases, experts select a centralizer-type clamp, designed for centering and tacking pipes previously located in the desired position. Can also be used to connect welding parts.

Advantages of this type:

• ensuring tight contact;
• guarantees welding accuracy;
• Suitable for pipes of various diameters.

Flaws:

• limited scope;
• high cost compared to other types of clamps.

We recommend watching the video, which contains recommendations on how to extend the life of the complete mass of the crocodile and which one is better to choose for purchase.

And another review from an experienced welder, which has some tricks.

Popular models
