What are good welding electrodes?

The best electrodes for inverter welding

The ease of use of the inverter has made welding accessible to many craftsmen. This welding equipment has a control system, rectifier, filter, converter that supplies the required current.

The inverter provides direct current, the polarity of which can be changed during welding. A guarantee of a high-quality seam is the correctly selected operating mode of the unit and suitable electrodes for the inverter. There are a great variety of products.

Characteristics and sizes vary. To successfully buy electrodes for welding with an inverter, to determine which ones are best suited to each specific case, you need to delve into the essence of the process.

Principles of classification

There are several types of classifications of electrodes for inverter welding. The main feature that should be taken as a basis is the ability to melt. Rods that do not melt during welding are used to work in an atmosphere of shielding gas, such as argon.

Melting rods are used in manual arc welding with an inverter, which in practice is most often carried out at home. It is not the metal core that melts, but the coating applied on top. The components of the outer layer improve the properties of the arc and form a protective cloud over the working area.

When choosing a specific brand for an inverter, the amount of work, requirements for seam quality and advice from professionals are taken into account. You can look at specialized magazines to find out brand ratings.

But for home use, it is enough to carefully read the description on the packaging in order to understand what current and what materials the electrode is intended for welding . It is best to purchase products from a trusted supplier. To learn how to weld with an inverter, experts recommend rutile or basic brands.

Coating

When choosing electrodes for an inverter, the welding mode and the chemical composition of the consumable material are of decisive importance:

• electrodes coated with alkaline (basic) components are used if it is necessary to cook with an inverter at a constant current of reverse polarity. They are used to cook high-alloy steels;
• Rutile coatings can be used when welding with alternating and direct current of both direct and reverse polarity. Titanium dioxide (rutile) ensures easy ignition of the arc, and there is no spattering of metals during operation. This is the best option you can choose;
• for direct current (that is, an inverter), cellulose coating is suitable, which creates a good protective gas environment;
• rutile acid coating is suitable for welding metal with alternating current or an inverter (any polarity). Arc ignition occurs even at low voltage. It is important to note that when working with acidic compounds, dangerous fumes are released. Welding must be carried out with good forced ventilation.

The alloys from which the parts are made determines the type of core. The compositions must match each other.

The choice of electrodes is regulated by GOST. The standard stipulates not only the composition of the rods and coatings, but also the appearance, which excludes the presence of swelling, porous areas, and sagging.

Kernel

Electrodes for inverter welding are made from three types of materials: high-alloy wire, conventional alloy or carbon raw materials.

A novice master can navigate products by labeling. The more letters and numbers it contains, the higher the degree of doping. Each letter represents a certain additive, and the number next to it indicates its percentage.

For example, a product made of carbon steel is designated Sv-10G2, and a product made of high-alloy steel is designated Sv-30Х15Н35В3Б3Т. The difference is obvious.

Popular brands

Over the years of intensive work with inverters, a rating of the popularity of electrodes has been formed in the circles of welding specialists and home craftsmen.

The ANO brand is considered the most universal. Electrodes of this group allow you to make any welding joints: corner, butt, overlap. With this electrode product you can weld parts with a thickness of no more than 5 mm in any position, even in the vertical direction from top to bottom.

There is no need to thoroughly clean surfaces from oxidation products. These electrodes can be used for root welding of thick parts. If there is a rutile, cellulose coating, then connecting any polarity of the inverter is allowed.

The products of the MR line are presented in two categories. MP-3 works effectively with parts with varying degrees of contamination. Electrodes coated with a rutile layer are used for direct and alternating currents, for any type of inverter connection.

You need to choose a position for work, taking into account the diameter of the electrode. MP-3S products are convenient for welding in various positions. These electrodes can be used to connect parts with residual moisture.

The UUSI category is represented by electrodes for welding parts made of carbon and low-alloy steel alloys. The resulting seams are plastic, have high impact strength, and firmly connect structures for special purposes.

Electrodes coated with a base layer can be used with direct current, reverse polarity of the connection.

Electrodes marked OK 63.34 show good performance. They can weld thermally strong steels and alloys that are resistant to corrosion. It is possible to weld vertically structures of small thickness, make butt and overlap joints.

For welding structures that require high strength and reliability of the seam, electrodes of the OZS-12 brand are used. They operate on direct current of an inverter of direct polarity, as well as on alternating current.

It is also worth mentioning the brands ESAB, Lincoln, Electric, Resanta, Kobelco, which offer high quality products with rutile, basic and combined coatings. The price range here is different, and each buyer decides for himself which option is the best.

Diameter selection

When choosing a product, you should pay attention to its diameter. The thinner the design, the smaller the possible electrode diameter. For welding profiles, products with a diameter of up to 2 mm are sufficient.

By the way, you need to learn how to work with delicate products. Such electrodes quickly melt and are consumed. To work with them you must have special skills.

Depending on the diameter of the electrode, the current strength for welding with an inverter is determined. Recommended values ​​are often indicated on the top of the packaging. In general, the pattern is as follows: the larger the diameter of the electrode product, the higher the required current value.

A discrepancy between the thickness of the material, the diameter of the electrode and the current strength can deteriorate the quality of the welded joint and lead to the formation of pores in it.

Advantages

The above popularity rating was not compiled by chance, but due to the noticeable advantages of the listed products. Welding with its participation is carried out most easily by an inverter.

Difficulties in forming a weld can only arise due to the wrong choice of grade for a particular metal or alloy. When the work is carried out correctly, high-quality connections of any shape and location are formed.

Consumable electrodes of the indicated brands form slag, which, after performing its protective functions, is easily separated. There is no need to beat him for a long time and painfully. The quality of the seam will be immediately visible.

The presented types of electrodes allow you to work even with parts that have rust residues. Sometimes this feature is very important. When working in extreme conditions, there may not be time or opportunity to thoroughly clean surfaces.

Which electrodes are best for a welding inverter?

The connection of various metal products is most often performed by welding. For this purpose, special equipment is used, which includes both transformer and inverter units.

But even the simplest of them cannot work without electrodes. After all, in order to obtain a high-quality seam, it is necessary to melt the steel rod. But for each material, the electrodes for the inverter must be made of a specific alloy.

Only then can you achieve a good result.

Inverters and components for them

Modern welding units are very different from their predecessors. They have compact dimensions, light weight, and are easy to use and transport. But in order for the seam made using them to be of high quality, it is necessary to use correctly selected electrodes. The success of the welding depends 90% on this.

Design features and technical characteristics

What is an element that is so necessary when performing welding work? This is a piece of coated steel wire. It is necessary to maintain a stable arc, and also provides:

• Metal protection;
• Seam alloying.

However, the functional features of an element depend on its purpose.

Let's watch the video, types and their main purposes, as well as selection criteria:

The main technical characteristics of welding electrodes for inverters are:

1. Diameter and length of the rod;
2. The material or alloy from which it is made.

The length of the product can be from 300 to 450 mm and depends on the nature of the alloying of the electrode. As for the diameter, there is a whole line of rods, where the thinnest rod measures 1.6 mm, and the thickest reaches 5 mm. But welding electrodes with a diameter of 1.6 mm are usually produced to order, since they are not widely used in the domestic market.

Types of electrodes

As for the classification of these elements, they are divided into two main types:

1. Melting;
2. Non-melting.

The former can be made from either steel wire or special alloys, depending on what materials will be used for welding. Typically, when using a welding inverter with cast iron, copper, and dissimilar steels, electrodes made of alloys are used.

Non-consumable or tungsten products are used in argon welding. They may also have different performance depending on the application.

Table of types of electrodes

In addition, electrodes are divided according to purpose into the following types:

• For various steels;
• For stainless steel;
• For aluminum;
• Nickel;
• For repair;
• For difficult to weld alloys.

There are differences in the type of coatings. There are four types of electrodes on the market, the most common being: basic and rutile.

Criterias of choice

Since this consumable is necessary for any type of welding, it should be purchased taking into account the characteristics of the equipment and the specifics of the work performed.

Let's watch the video, types and their differences:

In this case, the following characteristics should be taken into account:

1. Diameter;
2. Composition of the material.

To make a quality seam, you need to choose the right consumables. And first of all, their parameters are taken into account, including diameter. And yet, which electrodes are better for an inverter? For various steel grades it is specified in regulatory documents. But it should be taken into account that the nominal diameter corresponds to the dimensions of the internal rod and does not include coating.

The thickness of this layer is individual for a specific type of product and is marked with the letters:

M - denotes a small diameter and a small layer of coating up to 1.2 mm, and D - over 1.8 mm. Both domestic and foreign companies adhere to this marking. However, their diameters will be different.

Watch the video on how to choose the right electrode for welding:

But not only dimensions are important when choosing electrodes. The composition of the components in it also plays an important role. Since the electrode consists of a rod and coating, the material from which they are made is also taken into account. For most products, low-carbon wire is used as the basis, and the coating composition includes various components:

• Fluorine compounds;
• Titanium dioxide;
• Rutile.

The use of electrodes of the first type makes it possible to achieve a strong and heat-resistant connection characterized by good ductility. Products with titanium dioxide create a stable arc and achieve high joint strength. Rutile electrodes are used when welding structures with high humidity. In addition, when choosing electrodes, the characteristics of the metal being welded must be taken into account.

For example, for carbon steels, UONI or MR rods are used. The former have a low level of spattering, the latter are characterized by rapid slag separation. They can be used in both professional and portable equipment.

Manufacturers – whose products are better

Since there are a large number of different brands and types of such products, we will consider only those that are intended for manual welding. Moreover, from them we will select only samples used when working with carbon and low-alloy steels.

Watch the video, test various welding electrodes:

We will be based on reviews left by users, as well as publications from specialized magazines. According to these sources, the best electrodes for inverters on the domestic market are products from the following factories:

• St. Petersburg ESAB-SVEL;
• Tyumensky;
• Kamensk-Shakhtinsky;
• Orlovsky;
• Losinoostrovsky.

Among foreign manufacturers, the products of the following companies are in greatest demand:

These electrodes for inverter welding are superior to domestic products in many respects, although they have a rather high price.

Watch a video about Monolith products:

As for Russian products, they are inferior in most options, although some samples are already appearing that rise to the level of the most inferior imported electrodes. But even then, only joint ventures owned by European or Asian manufacturers could achieve such results.

Now let's move on to considering the products themselves. Thus, electrodes from the St. Petersburg plant cost about 135 rubles per 1 kg and, according to welders, are the best among domestic models.

The price of electrodes for inverter welding from a Tyumen company is slightly higher, although their quality is practically no different from the previous sample.

The products of the Kamensk-Shakhtinsky plant are mainly designed for use with household inverters and have a price of about 130 rubles. for 1 kg.

Penza electrodes are considered the best in terms of price and quality. Their cost does not exceed 58 rubles.

Although the products of the Japanese company are expensive, they allow you to achieve excellent results when testing for strength. Experts say that these electrodes fully justify such a high price.

Professional advice for proper use

The welding process cannot be called simple, so before you start assembling a certain structure using it, you should first practice if you have never done this before.

To do this, the clamp is attached to the part, and the electrode is inserted into the holder. Then the current is set according to the diameter of the steel rod. At the same time, you should study on new electrodes - this will help you better understand the meaning of the work.

Watch the video, basic welding skills:

Creating an arc is done as follows. The electrode is installed at an angle of about 70° to the part. Then they quickly pass it over the workpiece, and a sheaf of sparks and a characteristic sound should appear.

Next, you need to touch the part so that a gap of up to 5 mm appears. At this time, an arc appears and under its influence the metal will begin to melt. The gap must be maintained by moving the electrode horizontally as it burns out.

If sticking is observed, it means that the current on the device is set to low and it needs to be increased.

After the seam is completed, you need to make sure that it is of high quality. To do this, after the part has cooled, you need to knock at the welding site with a hammer. This will cause the slag to fall off and reveal a shiny, clean weld.

The best electrodes for welding

Nowadays, stores offer a wide selection of welding electrodes. They all differ in characteristics, quality and, of course, price. Sometimes a salesperson in a store offers what he thinks are good electrodes for welding, but in reality it turns out that their quality does not suit your work. It is not easy for novice welders to understand such a variety, so many purchase the most budget-friendly components, which is not always the right decision.

We analyzed reviews from professional craftsmen and compiled a rating of electrodes that will make the welding process better and more efficient. Here we will tell you which good welding electrodes a beginner should choose and which welding electrodes are best for a wide range of tasks.

Popular manufacturers

Electrodes of varying quality are produced all over the world: from Russia and China to America and Germany. Foreign rods, as a rule, are more expensive than domestic ones, but many welders believe that our products are not as bad as they say.

By purchasing, say, American electrodes, you can be sure of their quality and good performance, but you have to pay twice as much for this. And at the same time, by purchasing Russian electrodes you get a lower price, but at the same time less strict quality control in production. Which country's electrodes are better than others is a long-standing topic of debate.



We will not argue that domestic electrodes are definitely worse; we will give you this choice. We will only tell you about the best electrodes that we were able to try.

So, what electrodes do we recommend for purchase? Judging by the reviews and our experience, the best welding electrodes are produced by the brands ESAB, Kobelco, Resanta, UONI and Lincoln Electric.

Some manufacturers specialize in the manufacture of electrodes of one type, while others produce rods with both basic and rutile coatings.

SSSI 13/55

Let's start with the 13/55 model from the UONI company. These electrodes are used for direct current welding. We recommend them for welding complex metal structures with increased requirements for the quality of welds.

A distinctive feature of this model is the coating, which releases carbon dioxide during combustion. Thanks to this, the welding zone is always protected from the negative effects of the atmosphere. Such electrodes are inexpensive, but are sold in large packages of 3 kg.

They are available in almost any specialty store.

But this coating also has a negative side. Beginner welders often find it quite difficult to ignite this electrode, especially repeatedly. To solve this problem, you can clean the end of the electrode after use, removing the melted coating, but this requires additional time.

Kobelco LB-52U

These are Japanese electrodes of the highest quality and the highest price.

Which electrodes are best to choose for welding with an inverter machine: brands, choice of diameter and current strength

The welding process is quite unsafe, so it is important to use high-quality and proven equipment. An inverter welder is a modern and perhaps one of the best types of welding machines. The ease of working with them is one of the main advantages of household inverters, which have received justified and well-deserved love from craftsmen.

To make the right choice, you need to be able to read the accepted markings; they will tell the buyer what type of work this device performs:

• MMA marking means that the device operates on electrodes in arc welding mode.
• The MIG or MAG markings indicate a semi-automatic inverter, where wire is used instead of electrodes. For semi-automatic welding mode, you will need carbon dioxide in cylinders.
• TIG marking for argon welding machines, used mainly in the production of complex metal products in enterprises.
• The CUT marking indicates that the devices can perform plasma cutting of metal

MMA inverters are an excellent and practically the only solution when it comes to choosing welding machines for the home, cottage, and small periodic work.

Inverter models from well-known manufacturers, such as Resanta 190, are fairly inexpensive, reliable and easy-to-use welding machines, easy to use even for beginners, and allow you to quickly obtain high-quality seams.

Other markings suggest that the devices are used for more serious industrial purposes.

A feature of inverter welding machines is the generation of alternating current voltage. They are used for fusion arc welding. Current is supplied to the weld through metal rods called electrodes.

Classification of electrodes

The choice of electrodes presented in stores is very wide, from the manufacturer to the prices. Let's look at how they differ.

Electrodes are divided into:

• consumable, used in arc welding;
• non-consumable, suitable for argon welding.

Electrodes are distinguished by:

• composition of the coating or coating;
• material of the welded mass;
• diameter

During welding, the core begins to melt, which is accompanied by burning and melting of the coating, which turns into a gaseous state. This gas prevents oxygen from entering, and the molten part spreads over the metal, adding protection.

That is why you should not allow chips to appear on the coating. During the welding process, a damaged shell will lead to non-uniform heating, which will adversely affect the quality of the seam.

There are 4 types of coating:

• basic;
• sour;
• rutile;
• cellulose

Electrodes with coatings of the first two types are most often used.

Of the main ones, SSSI 13/55 is usually chosen. The welds are of high quality, excellent impact strength, ductile and durable. When installing critical structures with harsh operating conditions, these are the optimal electrodes for inverter welding.

Attention! If the coating is not dry enough, the joints of the parts have traces of rust, are not sufficiently degreased, or there is any contamination, then the weld may turn out to be porous. Operate only with direct current, the polarity must be reversed.

Let's consider the second type of electrode coating for rutile-type inverter welding. Traditional MP-3 manufactured by Resanta are used for connections made of low-carbon steel. They are distinguished by stable arc burning, and the current can be either constant or alternating. When welding, the material does not splash, and the seams can be horizontal or vertical. The slag is easily separated. Rust and dirt do not interfere with welding and do not affect the quality of the seam.

What electrodes are best for cooking with an inverter? Dry, without damage. They must be stored in a dry place, avoiding deformation of the rods; during use, this will prevent the electrode from sticking to the metal during operation.

The most widely used brands of inverter electrodes are:

• MR-3, UONI 13/55, OZS-4 connect low-alloy carbon steels and are used for welding critical structures;
• TsL-11 is chosen for welding stainless steel and high-alloy steel;
• OZANA-1 - for connecting aluminum grades A0, A3; and OZANA-2 - for alloys AL4, AL9, AL11;
• Komsomolets-100 - for welding copper and joining copper and steel;
• OZCH -2 is used for cast iron alloys.

Many inverters operate on DC current. There are 2 polarity connection options: forward and reverse .

With direct polarity, a ground is connected to the plus of the inverter, and a holder to the minus. This connection method increases the temperature of the metal; it is recommended for welding massive parts and if it is necessary to release a large amount of heat and high temperatures during the process.

https://www.youtube.com/watch?v=6F7MsWj2Mek

It is better to weld thin metal and high-alloy steel with reverse polarity so as not to burn through the material.

Determining the required diameter

Experienced welders believe that when welding with an inverter there is not much difference between the electrodes. The opinion is based on the personal experience of highly specialized specialists performing a certain type of work, for example, welding of the same type of pipes or profiles. In their work using an inverter, serious requirements for geometry and aesthetics are not imposed on the seam, so electrodes with a diameter of up to 2 mm inclusive can be used.

Thick-walled parts require longer welding time, so electrodes for welding them require larger diameters. Welding electrodes of small diameter burn out quickly; they are often used to make tacks.

To perform difficult work along long routes, thick electrodes have proven themselves well; the installation of lightweight structures with short-length seams can be performed with rods with a diameter of up to 2 mm. It is these electrodes that are used, in particular, when using household welding machines for inverter welding Resanta 190, for example, when installing gate frames and gates, making fences from metal pipes and corrugated sheets.

The diameter is selected based on the thickness of the metal of the workpieces, but for a thin sheet of metal up to 1.5 mm, it is better to use semi-automatic or argon arc welding.

Usually this is written on the product packaging, but if it is lost, you can navigate as follows: the welding current is set from 20 A to 30 A per 1 mm of electrode diameter. If the diameter is 3 mm, the current value will fluctuate between 80-110 A

But it also requires taking into account the mode of laying the seam, how it is laid, continuously or with a break. In the first case, take the indicator 20 A in the calculations, in the second - 30 . In addition to this recommendation, consider the following list of welding mode criteria:

1. Fluidity of the welded metal.
2. The speed of the welder when laying a seam.
3. The position of the electrode during welding, since in the ceiling position the current is reduced.

The optimal regimen will come with practice and experience. Pay attention to the weld pool, it is an indicator of the quality of the selected mode. The correct seam will be uniform if there is an influx of metal in the bathroom: this means that either the arc is short, or the welding speed was slow. In the case where a saddle formed in the bathroom, the seam was welded quickly, or the arc failed to be longer than required.

Correctly selected high-quality electrodes will allow you to weld any metal at a high professional level, even for novice owners of inexpensive household inverters.

electrodes for welding with inverter

The use of inverter welding machines is especially popular among beginners and garage craftsmen, since such machines are easy to use and allow many types of welding work to be performed efficiently.

But, despite the ease of operation, the use of an inverter welding machine requires the use of certain types of electrodes for operation.

High-quality electrodes help produce reliable and durable welds, and this topic is especially relevant for welders performing custom work, when durability and quality come to the fore.

The modern market offers dozens of types of electrodes for welding machines, and sometimes it is not easy to know which ones are best. What rods can be used for cutting metal with an inverter or for welding with an inverter, how to choose the right electrodes, their diameter and purpose? We will answer these and many other questions in this article. With the help of our article, you will be able to make the right choice of electrodes for welding with an inverter and find out which electrodes a beginner needs first.

How to choose electrodes for inverter welding

When choosing the best electrodes for welding, it is important to consider that the quality and durability of the weld largely depends on the selected components. You should not chase the most affordable price when choosing electrodes, as this may cause poor quality work. Of course, a professional welder will be able to make a perfect seam using any electrodes, but this is only the result of many years of practice. If you do not have much experience, it is better to overpay but get a decent result.

There are several most common brands of electrodes that are popular among beginners and practicing craftsmen:

• ANO brand: rods of this brand are highly flammable and do not require calcination. The brand is popular among both beginners and professionals.
• Brand MP-3: universal, most common. They can even be used to connect parts that have been subject to mild corrosion.
• Brand MP-3C: electrodes of this brand are best used if you need to make a particularly strong and neat seam.
• Brand UONI 13/55: allows you to make seams of the highest quality. This brand is preferred by highly qualified welders, since their experience allows them to easily perform work quickly and efficiently. It will be difficult for novice craftsmen to work with electrodes of this brand. If you need an aesthetic seam, but lack experience, choose the MP-3C brand.

In addition to the brand, there are a number of other important characteristics, which we will discuss below.

Diameter

When choosing welding electrodes for inverters, it is also important to take into account their diameter. Of course, if you use an inverter welding machine, then there is no point in placing increased demands on it, so you can use rods up to 2 mm. Many welders with ten years of experience talk about this, but they do not take into account that such work can only be performed with a limited number of parts. If you want to perform various types of work, then the diameter of the electrode must be chosen more carefully.

For example, which electrodes are best for welding with an inverter if the metal is thick? After all, such a part requires long-term calcination. You can spend a lot of time and effort using the usual small-diameter electrode, but we recommend simply choosing a larger diameter. The thicker the metal, the larger the diameter of the electrode.

Which electrodes are best for an inverter is also influenced by the specifics of your work. If you have to do routing work, we recommend choosing a larger electrode diameter to make work easier and reduce time. At the same time, electrodes with a diameter of up to 2 mm are quite sufficient for welding profiles.

With this diameter you can even weld sectional car doors, not to mention simpler structures.

Purpose

In addition to brand and diameter, they are divided according to their purpose. This also determines which electrodes are best for the inverter. Conventionally, they are divided into the following electrodes:

• For welding carbon or low alloy metals.
• For welding parts made of durable heat-resistant metals.
• For working with stainless steel.
• For working with aluminum and copper alloys or directly aluminum and copper.
• For welding cast iron parts.
• For minor repairs and surfacing.
• Universal-purpose electrodes used for welding parts made of unknown metal.

Coatings

Manufacturers often apply special coatings to electrodes to improve their performance. Among the most common coatings are basic and rutile. The base coating is the most popular and is used by a large number of manufacturers. Thanks to him, it is possible to obtain a high quality seam. Well, in combination with the correctly selected electrode diameter and extensive experience, the welder is able to make a weld of the highest quality and weakly subject to mechanical stress.

Rutile coating is popular among craftsmen working with low-carbon steel. Thanks to this coating, the formation of pores in welds is eliminated; such electrodes can be used with alternating and direct current, and can be reused. Also, electrodes with rutile coating are simply more convenient to use when performing work in hard-to-reach places; when melted, such a coating does not emit hazardous substances (unlike other coatings), which allows you to maintain health.

How to perform high-quality welding with an inverter

Using an inverter you can get a fairly high-quality seam, but for this you need to take into account three important parameters:

• Correctly set current strength for welding;
• Optimal diameter of the selected welding rod;
• Accounting for metal thickness.

As mentioned above, the thickness of the electrode is one of the main factors in the quality of the weld. Let us add that the current density also depends on the diameter. If you exceed the density value, the arc will lose its stability, it will be worse to weld the metal and the width of the seam will increase significantly.

This is not critical if the aesthetic side of the work is not so important. It is better to entrust welding of thin metals to semi-automatic welding machines. Otherwise, the seam may turn out weak and too wide.

This is especially critical when using large-diameter electrodes: pores form in the weld, significantly reducing its strength characteristics.

Pay attention to the current setting. The most convenient way to find out the recommended amperage is to simply look at the packaging. Most manufacturers indicate all the necessary information on it.

Foreign manufacturers

Answering the question “Which electrodes to choose for welding with an inverter?” It is worth mentioning foreign manufacturers. There are many brands on our market, but we will focus on European ones. In our opinion, Abicor Binzel, ESAB, Böhler Welding and ELGA are the best.

Whatever manufacturer you choose, their products can be used to carry out all types of welding work: welding carbon steel, pipe joints, performing particularly complex work with difficult-to-weld metal, welding cast iron, copper and aluminum. If you cook to order or perform work with an increased degree of responsibility, then choose foreign manufacturers. Their quality is many times higher than the products of Russian manufacturers, since there is strict control in production.

the best welding electrodes for a welding machine 2018 – 2017

It is very difficult for professional builders and welders to find professional tools and high-quality consumables on the Russian market. Electrodes are consumables, but the quality of the seam and the reliability of the welded structure depend on them.

Before rating the best welding electrodes for machines and welding inverters, we talked with professional welders.

Everyone unanimously says that they prefer to use foreign consumables, since Russian ones, unfortunately, cannot yet compete with them.

Before we move on to the rating of electrodes, for beginners, we will say that they are divided into two categories: rutile and electrodes with a basic coating. Rutile electrodes can be used on welding machines with direct and alternating current. They are easy to re-ignite, including re-ignition.

They have good properties against dampness. Electrodes with a basic coating are used in conjunction with a direct current device. They are used in cases where the quality of the seam must be the most reliable. During operation, carbon dioxide is released, which reduces the risk of oxygen entering the seam.

Welding electrodes: which ones are best for an inverter?

Many novice welders are wondering which electrodes for an inverter are best to choose. After all, this equipment is most often used by home craftsmen. In general, welding inverters have replaced transformer units that were used before quite a long time ago. This is due to the fact that the inverter is easy to operate, inexpensive, and in addition, it can be used to weld metal parts and structures quite quickly.

Such equipment is usually used in fusion arc welding. Inverters are characterized by constant stability and welding current, which ensures a super-strong connection due to the high quality of the seam.

The electrode plays the role of one of the main components of the described welding. These are metal rods that are necessary to supply current to the welding zone. In this case, it should be taken into account that welding units come in different types.

Therefore, they require different electrodes.

Which electrodes to choose

If you, too, were among those who wondered about which electrodes are best for an inverter, then you should read the information presented below. Consumable-type electrodes used in inverter and in general arc welding are made from welding wire, in the process of which state standards of 1970 are used.

According to GOST 2246, electrodes for inverter welding are classified into:

• alloyed;
• carbon;
• highly alloyed.

The first ones are made from the following types of wire:

• Sv-08Х3Г2СМ.
• Sv-08HN2GMTA.
• SV-08KhGSMFA.

When deciding which electrodes are best for inverter welding, you should become more familiar with carbon rods, which are made from wire Sv-08 and Sv-08AA, etc. High-alloy electrodes are based on wire Sv-30Х25Н16Г7 and Sv-01Х23Н28М3Д3Т. However, none of these lists can be called complete. The rod is coated by pressing. It protects the weld pool from atmospheric influences and allows the arc to burn more steadily.

Beginners should know that electrodes can be classified into two subgroups. The first provides products intended for making seams when connecting critical metal structures. The second subgroup is intended for work with conventional connections.

For critical products, it is best to prefer UONI or ANO electrodes.

If you are faced with the question of which electrodes are best for an inverter, then you should also pay attention to products marked MP-3, which are intended for conventional welded joints. The SSSI brand of electrodes is quite capricious.

This is due to the fact that not every novice master will be able to work with such rods. If you do not have experience in such activities, then it is better to avoid such electrodes.

Popular types of electrodes

If you cannot decide on a choice, then you should pay attention to the most popular brands, they look like this:

• UONI-13/55.
• MR-3S; MP-3.
• ANO.

The former are popular among experienced craftsmen. These rods allow you to achieve a high-quality seam, which is true at low outside temperatures. At the same time, the density indicators remain optimal.

When deciding which electrodes are best for an inverter, it is worth paying special attention to MP-3C rods, which are used when it is necessary to make a weld with high quality requirements. These electrodes are used to connect elements with direct and alternating current of reverse polarity.

The most universal brand is MP-3; it can be used to connect metal workpieces with a contaminated surface, rusty and damp structures. The most purchased among Russians are ANO. They do not require pre-calcination, and you can light them without much effort. In the end, you are guaranteed to get an excellent result, even when welding is performed by an inexperienced welder.

Selecting electrodes for different materials

Before starting work, you need to remember that products made from different materials require certain electrodes. If you plan to work with high-alloy or stainless steel, then it is best to use TsL-11 rods, which are manufactured according to state standards 9466-75. But if you plan to weld workpieces made of carbon steel, then OZS-4 electrodes are best suited.

If you are still deciding which welding electrodes are best to choose for an inverter, then you should pay attention to ANO-6. They are intended for products made of low-carbon steels. In this case we are talking about rods with ilmenite coating.

Low-carbon steels can also be welded using ANO-4, which have a rutile coating. Different grades of cast iron can be connected using OZCh-2. When purchasing electrodes, you should ask whether they have epidemiological certificates that guarantee high-quality welding. The use of material manufactured according to state standards also speaks about the safety of work.

For reference

An inverter is modern equipment with which you can weld different surfaces using almost all existing types of electrodes. This is the popularity of the device. However, when choosing the best welding electrodes, you must remember that not all rods provide high-quality results and excellent presentation of the seam.

In addition, safety issues will be compromised when using rods that are not recommended for this type of welding. This suggests that when choosing rods it is necessary to follow the recommendations of specialists.

Selecting electrodes for the Resanta device

Regardless of what brand of machine will be used for welding, the electrodes are selected according to the scheme described above. If you are faced with the question of which electrodes are best to choose for the Resanta 190 inverter, then you should be guided by the current settings and the diameter of the rods. The last parameter is selected depending on the thickness of the workpiece. If it is 1.5 mm or less, then it is better to use argon arc or semi-automatic welding.

Which electrodes are best for the Resanta inverter is of interest to many. Answering this question, it can be argued that the diameter of the electrode is selected, as mentioned above, according to the thickness of the steel. If it is 2 mm, then the diameter of the rod can vary from 2 to 2.5 mm. With a steel thickness of 12 mm, it is best to choose an electrode with a diameter of 5 mm.

Additional recommendations

When choosing the best electrodes for welding, you may be faced with the need to purchase a rod for a 13 mm workpiece. In this case, the diameter of the electrode will be 5 mm. This parameter will also be relevant for workpieces of more impressive thickness.

But as for the current, it is set depending on the diameter of the electrode. Thus, based on 1 mm of diameter, it is necessary to set 30 A. For a 3 mm rod, the current can be 80-110 A.

The final value will depend on the spatial position, the number of passes and the thickness of the metal.

Finally

If you have already decided for yourself which electrodes are best for the Resanta 220PN inverter, taking into account the above recommendations, then you must remember that identical and precise settings do not exist today. The wizard sets the current parameters independently using the method of error and trial. At high currents, you must be prepared for the weld pool to become less controllable and more liquid.

Which electrodes are better for welding with an inverter?

Welding is an interesting and entertaining process. They study this for years, and during practice they master new methods and technologies. You can understand what welding is and how to operate a welding machine remotely, if you have the inclination and desire to do so.

The most basic “ingredients” for joining two metal parts using an inverter are welding current and an electrode.

We will dwell on these concepts in more detail, since a novice welder can easily get confused in the huge assortment of electrodes presented by manufacturers.

What is an electrode and why is it coated?

An electrode is a thin metal wire, and its coating is sprayed with a special compound.

When heated, the metal of the rod melts, and along with it its coating, which forms a protective dome around the weld pool, preventing contact with oxygen.

This composition also covers the welding seam with a thin film, which serves for a long time without corroding. The electrode can be compared to a pencil, where the lead is a core packed in a coating, that is, a wooden base.

What to look for when buying an electrode?

When starting work, carefully inspect the electrode. There should be no uncoated areas on it. If you use a defective product, you will not achieve an even seam. At the end of the electrode, the coating should be the same size on all sides. Only in this case will the welding arc be placed in the center. If there is more coating on one side, then when the arc burns, you will find its displacement. For professionals this does not matter much, but a beginner can be very disappointed.

Wet electrodes make it very difficult to ignite an arc. Therefore, it is worth taking care of proper storage. Experts advise calcining the electrodes in the oven and packing them in a sealed bag with the addition of several bags of salt. Salt absorbs excess moisture, and working with dried electrodes is much easier.

You should not initially purchase wet rods; universal coatings are especially susceptible to moisture absorption, but if it happens that the electrodes need to be dried, then read the instructions, which indicate the drying time and temperature. Let us immediately warn you that after drying, the quality of welding will decrease. Store the electrodes in a well-ventilated area and do not operate in a damp area or during rainy weather.

Types of coatings and what they are used for

There are about two hundred brands of coatings, and only one hundred of them are suitable for manual welding. Manufacturers make four types of coatings:

• basic;
• cellulose;
• rutile;
• sour.

The first two types are used only for direct current operation. They provide a reliable and soft joint that can withstand impacts.

The last two coatings work with alternating and direct current. But acidic coating is very poisonous, so you should have an additional powerful hood. The main component of rutile coatings is titanium dioxide. They range in color from greenish to blue. Ideally ignite the arc and operate at low currents. When welding, it does not spray metal drops, but the finished seam will have to be cleaned of slag using a special hammer.

Which electrodes are suitable for welding with an inverter?

The composition of the wire should be from the same metal that you are going to weld. If the working material is made of stainless steel, then the core should also be made of stainless steel, and similar electrodes also exist for iron-carbon and heat-resistant alloys.

For work at home, brands of electrodes such as UONI13/55, MP3, ANO21, OK63.34 are well suited. These brands are recognized as the best for welding work using the inverter type of welding. They provide a high-quality weld and are ideal for people without much practical experience.

Let's look at these brands in more detail and describe all the characteristics of working with them, as well as their advantages and disadvantages. Here is a small ranking of popular brands.

UONI13/55

These are universal coatings often used in welding carbon-containing and low-alloy alloys. Used to connect load-bearing structures. The seams are shock-resistant and can withstand temperature changes well.

The disadvantage of this coating is that the surface must be carefully prepared. The slightest ingress of grease, dust or other foreign particles will lead to porosity of the seam.

It is used only with direct current operation; you need to monitor the polarity, connect the plus to the electrode, and weld with a short arc.

MP3

These are ideal coatings for beginners. We recommend starting with them. They melt easily, even if the power of your inverter device is low (for example, models for home and garden). Provide complete protection of the weld pool and give control over its condition.

They work with devices on direct and alternating current, and with inverters on reverse polarity. They can make different seams, but with vertical seams it’s not so easy. The requirements for cleaning the surface are not as fundamental as those of the previous type; they can hold even dirty parts together. Welding takes place with a two to three millimeter arc.

The arc is stable and many beginners can easily cope with welding with these electrodes.

ANO21

These rutile electrodes are also popular, but are used for welding carbon-containing metals that are not very thick. The welding arc is ignited simply even if it occurs again. The electrodes must be dried before use at a temperature of 120 degrees for 40 minutes. You can work with currents of any polarity. The finished seam looks like it has small waves and the slag is easy to clean off. Used for welding water and gas pipelines.

OK63.34

This type is intended for working with stainless metals, but is also quite suitable for structural alloys. When welding with direct and alternating currents, polarity is not important. The slag comes off easily, and the seam looks slightly textured. Welds vertical joints up to 6-8 mm. Widely used for overlap welding and multi-pass welds.

Electrode size

Everything is very simple here. The diameter of the electrode depends on the thickness of the metal being welded. It must match his size. If you are welding metal with a thickness of three millimeters, then take a three-piece electrode, if 4 mm, then a four-piece. But you need to start with the optimal size, which corresponds to a value of 3 mm. This is a popular size and it is easier and more convenient to work with. As your skills increase, upgrade to larger diameters.

Current polarity, plus or minus

The packaging of the electrodes always indicates which polarity the work should be carried out from. With reverse polarity, the electrode is connected to the positive, and the negative terminal is connected to the part. With direct polarity, it is the other way around, minus to the electrode, plus to the metal.

What is the difference between these connections? The difference is in the movement of electrons. According to the laws of physics, the flow of electrons tends from minus to plus. Accordingly, where there is a plus, more heating occurs.

Thus, by changing the current polarity connection, you can control the heating of the part that is needed during the welding mode.

For example, you need to weld metal with a thickness of 2 mm and an electrode of 3 mm. In this case, the plus must be applied to the electrode so that it heats up more, since if the plus is placed on the part, the material will burn through, so it is better to work with reverse polarity. Or you need to connect metal with a thickness of 7 mm with the same electrode. Here it is better to use straight polarity and apply plus to the metal, which will warm up better and the seam will be strong.

How to set the current strength

The traditional choice of welding current is calculated by the size of the electrode. One millimeter of diameter corresponds to 20-30 amperes of current. Another indicator is the type of seam, what it should be - intermittent or continuous. In the first option the current should be lower, in the second higher. But these are very average indicators, which can only be used as a basis at the initial stage of welding. Over time, you will be able to accurately set current parameters.

For an electrode diameter of 3 mm, the welding current should be 60-90 Amperes. But the inverter operates in a mode from 30 to 140 Amps. For a continuous seam, the current is set in the range of 90-120A, for an intermittent seam - 70-90A. But again, everything is relative. There are also indicators such as speed of movement, coating grades, metal spreading, and type of seam. For horizontal and vertical joints, the power is reduced, for ceiling joints - generally to a minimum.

Therefore, we advise you to start with the standards, and as you work, set the mode that is convenient for you. Through trial and error, you will develop a relationship between adjusting the welding current and the speed of electrode guidance. Focus on the weld pool - it should tell you more about the mode of the selected parameters than words.

6 best welding electrodes

Nowadays you can easily find a wide variety of welding electrodes in specialized stores. They differ from each other not only in characteristics, but also in reliability. Unfortunately, very often people purchase products that can last an extremely short period of time.

Our site strives to prevent this from happening. Stop wasting your money! Buy a quality product that will serve faithfully for a long time. Perhaps you will overpay slightly. But eventually you will realize that you actually saved money.

In a word, choose those welding electrodes that are mentioned in our article today.

Which brand of welding electrode should I choose?

Now welding electrodes have learned to be produced in a variety of countries. They are created in China, Russia, the USA and many other countries. Unfortunately, practice shows that domestic electrodes are inferior to foreign products in terms of quality and other parameters. And yet progress is noticeable.

If this continues, in a few years the level of performance will become much higher. In the meantime, along with electrodes from Russian companies, we will also recommend products distributed under foreign brands - they often show themselves in work from a more positive side.

The most popular welding electrodes in Russia are under the following brands:

1. ESAB-SVEL

2. Kobelco

3. Resanta

4. SSSI

5. Lincoln Electric

Some of these companies specialize in producing both rutile and basic coated electrodes. Others create electrodes of strictly one type.

OZL-8

These domestically produced electrodes are primarily intended for welding steel with a high nickel and chromium content. That is, these are the electrodes that should be used to weld stainless steel. This product has one limitation. It is only suitable for welding machines using reverse polarity direct current. The arc should be short.

If the above conditions are met, the welder will receive a strong weld that is not prone to hardening and corrosion. In a word, OZL-8 electrodes show themselves ideally when working with highly loaded components, including those used under conditions of alternating loads.

Unfortunately, after welding, some slag is released into the light. But it separates easily, you won’t spend a lot of time on it. When cooling, the seam does not crack, but it should not be cooled sharply so that crystallization does not occur, which reduces strength. Like other electrodes with a basic coating, these products require calcination at high temperatures. This makes ignition somewhat difficult, or rather delays.

Advantages:

• Easy seam management;
• Ideally welds highly loaded components;
• Does not crack when torn off;
• Best suited for working with stainless steel.

Flaws:

• High price;
• When humidified, the characteristics seriously deteriorate;
• Usage restrictions typical for such electrodes.

Lincoln Electric Omnia 46

The most respected company in the welding market is Lincoln Electric. This American company has existed for over a hundred years. The first coated electrode was produced by her back in 1927. Since then, the engineers of this company have accumulated a wealth of experience. Therefore, you should not be surprised that Omnia 46 electrodes, which have a rutile-cellulose coating, immediately after their release earned the respect of many welders and specialized publications.

Despite their foreign origin, these electrodes are quite inexpensive. You can find different packs in stores; they usually contain from four to six kilograms of electrodes. In any case, you will spend less than a thousand rubles! Beginners love this product the most. The fact is that Omnia 46 electrodes easily flare up even on cheap welding machines.

They are not very sensitive to the length of the arc, which is also good news. Experts note a small number of sparks that occur during operation. This is important, as this improves fire safety. The slag can be easily separated after work, allowing welding of contaminated or rusty steel. Buyers have no complaints about the strength of the seam.

Often, even pipelines are welded with such electrodes, although they were not originally intended for this.

Advantages:

• The seam is very durable and resistant to stress;
• Does not require a short arc;
• Very easy ignition on any inverter;
• Even a beginner can handle the arc;
• Reasonable cost.

Flaws:

• Electrodes can quickly become damp (then they will require calcination).

ESAB-SVEL OK 46.00

These electrodes are both Russian and foreign. This is explained by the fact that they are produced here, but strictly under the control of the Swedish company ESAB. The product is sold at a relatively low price. This product has no equal in this price category. Even with partial dampness, the electrodes burn stably.

Ignition takes a matter of seconds on any welding inverter. You can work with electrodes with both direct and alternating current. Experts note that the product works in any direction of the seam, and the minimum current threshold for these electrodes is lower than that of competitors. All this allows the Swedish-Russian product to be used for welding thin-walled parts.

The main advantage of rutile-coated electrodes is that the surface of the steel being processed does not need to be cleaned. The product is not afraid of either pollution or corrosion. All slag can be easily removed after work. The cooled seam is strong and viscous. To calcinate a very cool electrode, it is enough to heat the welding machine to only 80-90 degrees.

Advantages:

• Can work with contaminated and rusty steel;
• The price tag can hardly be called high;
• Possible operation at minimum current;
• Very easy ignition.

Flaws:

• Not suitable for pipelines, since the strength of the seam is still not maximum.

Resanta MP-3

It is possible that Resanta MP-3 electrodes are the most common in our country. The Resanta brand unexpectedly became very popular, not least due to the fact that most often there are no special complaints about products under this brand.

The above electrodes have an average price tag. The product turned out to be successful, its main disadvantage is that it works noticeably worse when damp. If you need a strong seam, then the damp product will require calcination. At a temperature of 150-170 degrees, this process will last about an hour.

Like other rutile electrodes, Resanta MP-3 can be ignited with almost an ordinary match. This product also allows you to conduct an arc in any direction. It is not afraid of rust or contamination - the slag is then easily removed. The product has no particular defects.

While many competitors, when working with steel with a high carbon content, suffer from recrystallization, this product is completely insensitive to the quality of the steel being welded. And yet, there is no need to buy Resanta MP-3 for welding high-carbon steel - there are electrodes with a basic coating for these purposes.

Advantages:

• Optimal price tag;
• No tendency to form pores;
• The slag is easily separated;
• Minimum arc length requirements;
• Easy to light;
• Can be used with alternating and direct current.

Flaws:

• When dampened, the quality of the seam noticeably drops.

Which welding electrode to buy

1. If you have already worked with electrodes that have a basic coating, then you can purchase UONI 13/55. This product is inexpensive and provides a very durable seam. Also among its advantages is the fact that these electrodes can be found in many stores.

2. Kobelco LB-52U also has a base coat. In this regard, ignition here is possible only after calcination, which removes all moisture. This electrode must be purchased if a pipeline or some other serious object is being welded that does not allow double-sided welding.

3. If you are welding stainless steel, then you need to buy OZL-8. This is an expensive substance, but it is ideal for welding steel containing nickel and chromium. The product's disadvantages are typical for an electrode with a basic coating.

4. If you need fast-igniting electrodes, then you should consider purchasing the Lincoln Electric Omnia 46. Also, this product will not greatly affect your budget. The electrodes create a strong seam, otherwise they would not be included in our rating.

5. Another good example with rutile coating is ESAB-SVEL OK 46.00. This electrode also does not require serious calcination, and it is less afraid of dampness than others. To work with such an electrode, a minimum current is required, which allows you to weld thin-walled steel.

6. Resant MP-3 electrodes perform slightly worse. If they become damp, they will require long-term calcination at medium temperature. Otherwise, the seam will not be of the highest quality.
