A wide range of advantages of inverter equipment for welding has led to its spread in professional applications and among ordinary home craftsmen. Among the few shortcomings of such devices, high cost can be distinguished, but this factor will not be so significant if we turn to domestic products. At the moment, Russian-made welding machines are characterized by the optimal combination of working qualities, functionality and ergonomics. Of course, this applies to models from leading manufacturers, which will be discussed below.
Offers of the company "Cedar"
The company is rather modest and little-known even in the circles of builders. Nevertheless, she has been working in the segment of the production of electrical equipment since 1998 and during this time she has released a whole line of welding machines of Russian production with reasonable price tags. Of particular note is the MMA-220. The device works from a single-phase line at 220 V , so it can be used both in everyday life and on the construction site. The developers increased the accuracy of the current direction, sealed the printed circuit board and enclosed the functional base in an impact-resistant housing.
Since the model provides a maximum current of 220 A with the support of a power of about 6 kW , it can be used to perform complex joints of thick metal structures. For example, for installation work in professional construction this is the optimal solution. In addition, Russian-made welding machines of the Kedr company are distinguished by rich equipment. The basic delivery kits, in addition to the inverter, contain devices for grounding, a clamp for the electrodes, the necessary cable accessories , etc.
Model from the company "Caliber"
A more famous manufacturer of construction and industrial equipment, this time interested in the tool of the initial link - inverter MICRO SVI -205. The device is lightweight , compact and cheap (the cost is 4.5 thousand rubles), so it can be a worthy choice for use at home or in the country.
The current strength varies from 10 to 205 A with the support of electrodes with a maximum diameter of 5 mm. That is, with small sizes, the performance is average, but the workflow is quiet and withstanding long-term loads. Steel structures in a garage, for example, can be serviced without much discomfort. However, the absence of overheating as a sign of loss of stability in the operation does not at all mean that the device can work with increased loads.
Like all Russian-made inverters , this model is sensitive to voltage drops during arc ignition at maximum currents. Therefore, you should initially set the bar in the performance indicators with which the equipment will be used.
Welding machine "Drummer"
The variant of the initial class is also interesting in this line, the cost of which is the same 4.5 thousand. This is a UIS -160 inverter capable of performing operations with a maximum turn-on duration at currents up to 160 A. That is, the tool is light and convenient, but its performance is much lower than in the case of Caliber. What did the developers compensate for the lack of electrical potential? The increased class of protection is IP 21 . It makes it possible to use a welding machine of Russian manufacture UIS-160 in the most difficult conditions. The owners of the equipment indicate not only the physical protection of the case with small dimensions, but also the reliability of the arc support, albeit with small power indicators.
Svarog Products
This manufacturer specializes in welding equipment, so it makes sense to consider a professional model. The ARC 205BS inverter is also designed to work with 220 V networks, but at the same time it provides a current strength of about 200 A with support for a power potential of 6.5 kW . What is important for continuous work in production or car service, the continuous operation at maximum current reaches 80%. For inverter welding machines of Russian manufacture, this indicator is on average 40–60%, therefore, in terms of endurance and stability, this solution is very worthy. Additional ergonomic advantages include the presence of a digital display with the ability to visually control operating parameters. But the price of this inverter is considerable - about 14 thousand.
Model of the DON family
Solid in product quality, but not a very popular manufacturer of welding equipment. The average and most common solution to this line is DON- 200M . In creating the inverter, the company’s specialists also relied on increasing the active welding period, at the same time achieving an extension of the range of acceptable voltages - from 190 to 240 V. However, according to users, at low rates up to 190 V , the ignition sharply worsens. As for the current strength, at the maximum output it is 160 A. Power is 6.1 kW . Welders of the Russian production "DON" also have design features. For example, a U-shaped radiator layout is used in the case, which allows the integration of two fans. This increases the efficiency of the cooling system, minimizing the risks of overheating. The cost of this version is average by the standards of the segment - 8 thousand.
How to choose Russian-made welding machines?
The selection should begin with key indicators, expressed by the same current strength, and the diameter of the electrodes allowed for use. The larger these indicators, the thicker and denser the target blanks can be. For example, a device for 170 - 200 A , supporting electrodes up to 4 mm thick, can become a universal solution for complex work in the garage, in the country and at home.
Do not ignore the operating conditions, including voltage stability and temperature conditions. The admissibility of the use of equipment in certain conditions may expand or limit the possibilities of its operation. But the practice of application in this regard also confirms the universality of Russian-made welding appliances. The photo below also shows an example of the minimal technical equipment of a workplace in which an inverter is used.
Conclusion
In the general segment of construction and industrial equipment, domestic products are not always able to compete with foreign counterparts. In the best case, developers manage to get closer to competitors in terms of basic parameters, using their own advanced technologies. An exception can just be called welding machines of Russian manufacture, and in particular, Svarog and Caliber inverters. Under these brands the most reliable and technologically advanced models are produced. In addition, almost all manufacturers in this category produce devices with low price tags. At least when compared with foreign-made equipment.
