Top best welding inverters produced in Russia

Working with different types of metals requires having a mobile, reliable and highly functional tool. For example, repair garden tools, weld a complex engine element, gate, or create an exclusive structure from thin sheets of metal.

Any inverter welding machine made in Russia with MMA technology - electric arc welding with a stick electrode - can handle the implementation of these ideas at home. They are easy to care for, have a relatively light weight from 2.5 to 10 kg, and a wide range of models of varying power with efficiency up to 95%.

Features of choosing welding inverters

Many Russian-made semi-automatic welding machines on the market are either Chinese-made or Russian-Chinese with development and assembly in China, but with a domestic brand.

Inverters produced in Russia do not compete with China in terms of price, since labor in China is valued much less. Their main advantage is reliability due to assembly and well-designed circuitry. In comparison, foreign designs are much more expensive.

The main parameters that you need to pay attention to when choosing include:

1. Maximum value of welding current. The higher its strength, the stronger the result will be when using the equipment. For example, when using 3 millimeter electrodes at a current of 100 amperes, the equipment will be overloaded more than at 200 amperes.
2. The PV indicator is the value of how reliable the power part of the structure is. Shown as a percentage of the operating time at maximum with full current and the cooled time period. Equipment with a ratio of 60% will perform better than a tool with a ratio of 40%.
3. Ignition functions – they often make the process easier. Ignition occurs at high frequencies, and “anti-sticking” is present. If ignition is unsuccessful, the electrodes stick to the surface, which causes a short circuit at the equipment output. Based on this, the lightweight ignition function is not only convenient to use, but also protects the tool from overload.
4. Availability of a large number of functions. Domestic semi-automatic welding machines have an additional mode for manual welding of parts. The cost is slightly higher than the classic options, but it has versatility: it can weld a thick metal surface with deep penetration and cut it using an electrode.

Selection of welding inverters.
When choosing a welding inverter[/anchor], you also need to pay attention to the load on the equipment unit, that is, to the output stage of the converter part. Sometimes manufacturers show schematic diagrams of the power section.

The most easily understandable diagram of the conversion mechanism is the presence of one transistor switch in each arm. If the operation fails, the power of the system may drop sharply, making further operation of the equipment impossible.

For simple circuits, manufacturers often use IRF830 transistors, which have a typical drain-source resistance of 0.83 ohms.

With a large amount of current passing, the power to heat the part can be greatly reduced, which can subsequently cause overheating of the structure. The current reserve is also small - with a minimum long-term current, the voltage of the welding arc can also decrease, which will create difficulties when igniting and working with dirty elements.

Domestic equipment uses an expensive IGBT transistor, which has an increased maximum current and minimal resistance when open.

In each arm of the conversion mechanism, a pair of keys is installed in a parallel position so that the voltage drops during assembly and the individual keys heat up less than expected. For example, the “Kraton” has 4 switches arranged in parallel in the arms of the output stage, which gives a total of 88 amperes in each arm.

In addition, it is also worth noting that Russian welding inverters have a better build quality than their competitors. This can be seen in the soldering and circuit boards, which are coated with a special compound for protection.

Because of this, the effect of resistance to the penetration of excess moisture into the equipment, corrosion, metal dust and other possible damage that often occurs in Chinese structures increases.

Welding inverters - market overview

Today there are a large number of domestically produced welding machines. They are divided into transformers and inverters. In the first case, the structure plays the role of a current and voltage converter. Thanks to the transformer, the current is amplified several tens of times, reducing the voltage itself to 200 volts.

Due to this, power and energy are not lost. About 150 years ago, Russian scientist Nikolai Nikolaevich Benardos developed a method, which is still used today in the industrial sector, for welding metals using a welding transformer. Today, modernized welding devices have been somewhat modified.

In particular:

• low weight resulting from the built-in fan and cooling radiator, modified characteristics of the windings and core;
• A minimal electronics package is used, in particular a protective sensor against equipment overheating.

Table of models of welding inverters.
Another interesting type is Russian inverter-type welding machines. From the name you can understand that the tool inverts current with voltage. Compared with the previous type, inverters are produced based on different digital changes. This makes it possible to work with these equipment easily and conveniently.

The process itself does not cause difficulties. The tool is light in weight and does most of the work itself. Thanks to this, you can save time, work effort, ensure a safe process, etc. The only drawback for some craftsmen may be the price, which is slightly more expensive than welding transformers.

When considering the production of a welding arc and the operation of the entire welding machine, it is worth noting several main types that can be found on the modern market:

Equipment with piece electrodes

Top best inverters for welding.
Such inverter welding machines are the most popular among existing ones. The advantages of the designs include: economy, welding can take place in any position, regardless of space, there is no gas cylinder, compactness, mobility.

Disadvantages include low productivity and regular cleaning of slag from the seam in place of the welded elements. The mechanism of action is as follows: an electric arc melts the electrode rod, surfaces and the material itself.

After the electrode surface burns, a layer appears that protects the weld pool, in which oxygen is displaced. The metal rod melts in the form of drops, which are mixed with slag, after which it ends up in the weld pool and is mixed with the main material of the parts being welded.

The slag that has melted rises to the surface. It is worth noting that after it hardens, a plaque forms, which must be cleaned from time to time. Considering models for semi-automatic welding in this type, the following brands are distinguished - “Samurai”, “Paton”, “Atom”, “SSVA”, etc.

TIG Tools

They are used for operation with electrodes that do not melt due to exposure to the inert gas - argon. They are used only where a beautiful and reliable seam of welded surfaces is necessary.

The main features of this type include a seam with an aesthetic appearance, accuracy in operation, no splashes, you can weld surfaces with a thin layer, simple and convenient control of the characteristics of the welding arc.

The disadvantages include the fact that only a professional technician can work with such equipment, you also need to have an additional gas cylinder, and poor performance.

The mechanism of action of the design is that after the welding arc comes into contact with the surface to be welded, the material itself needs an additive. Argon creates a protective environment at the welding site.

The latest devices include “Bumblebee”, “Jasic”, “Modern Welding”, also the good “Forsazh-Torus” and others. These models are used for the argon arc welding process, welding various metals and alloys, regardless of their characteristics - aluminum with its alloys of copper, brass, bronze, titanium, cast iron, stainless steel, steel, etc.

Inverter for welding in argon.

Also, the semi-automatic welding process involves the use of equipment equipped with shielding gas.

The main advantages of this type include: high productivity, no slag emission, minimal amount of smoke during operation. The only disadvantages include the built-in gas cylinder and the difficulty of using the equipment in open space.

It is also worth noting that production plants of welding inverters are located in large cities of Russia, which makes it possible to purchase any model quickly, reliably and with quality.

The welding inverter works in such a way that, thanks to a special design through which the welding sleeve passes, welding wire is fed into the place of two parts being welded.

Gas also passes through the same part to protect surfaces. The master can control parameters such as wire transmission speed and welding arc power.

For semi-automatic welding, it is necessary to use flux-cored wire. In this situation, a gas cylinder is not needed, since the structure is always ready for use.

It is worth noting that flux-cored wire requires regular cleaning of slag; in addition, it is quite expensive compared to other additional parts.

Popular semi-automatic machines on the domestic market are considered to be from brands such as “Profi”, “Aurora”, “Volt”, “Elsva” and others. Among all the equipment, you can find more budget versions, however, no less high-quality and reliable in operation.

Advantages of inverter welding

Welding inverters are lighter than transformer ones and consume less electricity. They are easier to carry and can be connected to a household electrical outlet.

The inverter usually has a number of additional functions that make the welding process easier. The presence of artificial intelligence allows even people without work experience to cope with the creation of structures from pieces of metal.

Compared to semi-automatic machines, in which the electrode is continuously supplied to the welding site, and the welding itself is carried out in a protective gas environment, a conventional inverter is less expensive and more compact (there are no hoses or a gas cylinder). At the same time, the quality of the resulting seam is more influenced by the experience of the welder.

The best examples of Russian inverters

There are a large number of high-quality inverter welding machines made in Russia, but among them it is worth highlighting several basic ones that really perform their purpose well.

The weight of the structure is no more than 8.5 kilograms, and the kit additionally includes a 220-volt cable insert.

The plant has been producing tools since 2008. There are about 20 categories and over three hundred products available. The catalog contains manual arc welding, semi-automatic equipment and argon-arc structures.

Each product is protected by a special coating from sudden changes in voltage, has a minimal amount of splashes during operation, and the result is an aesthetic seam.

Inverters are considered an excellent tool in the professional industrial field. The company is one of the leaders in the domestic market and has branches in 80 countries around the world. Also has certificates according to international standards.

The universal model has a function for monitoring the pressure of the welding arc and a thermal protection mechanism. The devices can be used for highly complex work.

Welding inverters are manufactured in Russia, but the company was originally founded in Germany. Works with a mains voltage of 220 volts, conducts current from 10 to 150 amperes. Made from strong plastic. The kit includes a welding mask, several wires, a plug, a grounding clamp and an electrode holder.

Models of the Mosquito brand

A distinctive feature of all inverters from the presented company can be called versatility. The models are excellent for arc welding. Transformers in almost all devices are used with silicon filters. To monitor the operation of the devices, special current sensors are provided. The models can be used for welding steel surfaces. Capacitors in many inverters are used of the pulse type.

They cope with sudden surges in the network quite successfully. If necessary, the models can be transported. Inverters generally weigh no more than 8 kg. In this case, the modifications are desperate in terms of the number of installed coolers. If we consider models with a maximum frequency of at least 55 Hz, then they are produced with one fan. The average inverter from the presented company costs around 7,500 rubles.

Bottom line

Before selecting Russian-made semi-automatic welding machines for use, you need to find out how often it will be used for professional purposes or light work at home.

It is worth choosing a device based on these parameters, guided by savings. Using welding equipment from a domestic manufacturer, the welding reliability will be better, but more expensive - it can be stored in a room with high humidity, can withstand sudden voltage changes, etc.

Compared to the assembly of welding machines in Russia, Chinese equipment is not particularly reliable in welding seams. In addition, in terms of characteristics, the manufacture of welding machines is better in Russia than abroad.

You can save on this issue only if the purchase is for use several times. Then it is best to purchase the cheapest device so as not to waste effort, money and time on choosing higher-level equipment.
