Technological breakthrough in the field of welding equipment was the emergence of inverter machines. A fundamentally new method of powering an electric discharge arc has allowed manufacturers to reduce the weight and size of welding machines, while simplifying the performance of welding work due to a number of useful functions and combustion stabilization. Today, many companies produce inverter devices. One of the most popular is the Svarog inverter.
What is an inverter welding machine
The inverter apparatus is a unit assembled from several key transistors that converts direct current into alternating current at an ultrahigh frequency. The frequency of the current supplied in the standard city network is 50 Hz, while the rectifier and subsequent inverter increase it to 70 kHz. The frequency of the current directly affects the size of the power transformer and its mass. The higher the frequency, the more it will be possible to reduce the transformer without losing its power. By putting this principle into practice, manufacturers have succeeded in reducing welding machines by a factor of three, making them lighter and more compact.
Inverter welding machines, in addition to compactsize and lightweight design, have other advantages. The operation of such devices and their individual elements is controlled by one or more microcircuits located on the control board. Microcircuits regulate the arc burning mode and implement several functions at once, which are considered mandatory for modern models of inverter machines for aluminum welding:
- Hot start. Short-term increase in current for easier and faster arc striking.
- Anti-sticking. The inverter will automatically shut down if the electrode sticks.
- Arcforce. To prevent sticking of the electrode, the welding current is automatically regulated.
Inverter manufacturer Svarog
In 2007, a newcomer appeared on the domestic market of welding equipment - a welding machine of the Svarog brand. The manufacturer of the new device was Shenzhen Jasic Technology Development, a Chinese company represented in Russia by Insvarcom.
Products manufactured by a Chinese company are of good quality and affordable price, but do not belong to the premium class. The production of devices for welding "Svarog" is carried out on the basis of regulatory documents:
- Directives 89/336/EEC.
- Directives 73/23/EEC.
- European standard EN/IEC60974.
Certificates of conformity issued in accordance with the legislation of the Russian Federation confirm the high quality of aluminum welding machines of this brand.
Lineup
When developing the Svarog apparatus, the manufacturing company tried to implement all the functions necessary for welding. The company today produces about forty models, among which there are devices designed for manual welding, plasma cutting of metals and semi-automatic machines.
Separately, it is worth pointing out the marking feature of inverter welding machines "Svarog". In the field of production of welding equipment, there is an unspoken rule according to which the maximum value of the welding current is indicated in the brand of the device. A similar rule quickly dispersed among consumers who, when choosing welding machines, evaluate their capabilities without looking at the technical specifications, relying only on the marking.
The manufacturer of the Svarog 200 devices took advantage of this rule, indicating in the model markings numbers that slightly exceed the actual current strength, since from a legal point of view, the manufacturer can give his products any name. For this reason, when choosing welding machines of this brand, it is imperative to look into the technical specifications.
Machines for manual arc welding
Machines for manual welding "Svarog ARC 125" and "Svarog ARC 145" are used in domestic conditions for welding workpieces, the thickness of which does not exceed 3 mm. The compact dimensions and light weight of the devices make it easy to carry them from place to place and work with them in small spaces. importantthe advantage of these welding machines is the price: inverters are sold in domestic markets for 7-8 thousand rubles, which is a small cost for a very functional device.
Other models of this line, which are more powerful, can operate with currents up to 200 A, due to which such inverters are used at construction and installation sites, in many manufacturing and repair enterprises. The Svarog ARC 250 welding machine is the most powerful in this line - its maximum current is 225 A.
The combination of letters II indicated in the marking of the inverter welding machine means that the body of the device is made of high-quality plastic, respectively, it can be safely used in rooms with a high level of humidity.
Inverters for semi-automatic gas shielded welding
Welding machine "Svarog MIG 160" - the first of the devices in this model range, welding either with electrode wire or with separate electrodes in semi-automatic mode. This welding machine has a price of 25 thousand rubles. Despite the rather wide functionality, the most popular is another model from this line - "Svarog MIG 200Y", which is widely in demand in car services.
The inverter of this model is often used in the assembly of metal structures. Working with such a device at construction sites during high- altitude work is almost impossible due to too much weight of 25kilogram.
Industrial welding equipment
Svarog MIG 350 and Svarog MIG 500 semi-automatic two-block inverters belong to the category of industrial equipment. This also includes devices for plasma cutting of metal, argon arc welding and three-phase devices for MMA welding.
Inverters for TIG welding
Machines for TIG welding "Svarog", the range of which includes both universal devices that can switch to the standard welding mode using consumable electrodes, and pure "argons".
Advantages and disadvantages of inverters
The main advantages of Svarog brand welding machines are affordable prices and excellent equipment. Many semi-automatic inverters manufactured by this manufacturer come with a cable with a ground clamp and a welding torch, which is quite rare among similar equipment from other manufacturers.
Despite this, Svarog inverters also have their drawbacks:
- High cost of repairs. In the event of a failure of the Svarog welding machines, you will have to pay a large amount, which is not less than the cost of a new inverter.
- High demands on the operating conditions of devices - both household and professional models. It is necessary to take into account the temperature and humidity of the air, the dustiness of the room.
- Inverters produced by this Chinese company do not have a long service life: extremelyit rarely exceeds the warranty period set by the manufacturer.
The initial task of the manufacturer of welding machines "Svarog" was the creation and production of a budget line of inverters. Despite the shortcomings characteristic of equipment of this type, devices from the Chinese company Jasic are in great demand, since, as users note, they fully work out the funds spent on them. Svarog inverters are distinguished by good functionality, rich equipment, and the ability to work in rather difficult operating conditions. A wide range of models allows you to choose a welding machine that is optimally suited for the planned scope of work. Attractive prices make Svarog inverters affordable for the mass consumer. Minor shortcomings of the devices are fully covered by their advantages, reliability and quality of work.
