Welding machine "Svarog ARC 165": specifications, photos and reviews

In the conditions of intensively developing industry, one has to master more advanced and modern technologies. The use of generators and transformers in the work with metal products has already come to the fore. The place of these units was occupied by an inverter - a new welding equipment, which by its technical characteristics surpassed all its predecessors. One of the most popular among consumers is the "Svarog" brand inverter ARC 165 Case series J6501.

The article contains information on the characteristics, advantages and disadvantages of this unit.

Hardware properties

Unlike other welding devices, inverters are less dimensional and have significantly less weight. In addition, various types of electrodes can be used for working with inverters. The owners of equipment of the brand "Svarog" ARC 165 J6501 never have problems in the process of work with both black and non-ferrous metals. Inverters have a wide range of current and many different options, so they have proven themselves as universal and simple enough to operate units. Also, inverters are characterized by a high coefficient of efficiency (up to 90%). Unlike transformers, new devices are more economical, since they consume three times less electricity.

Principle of operation of inverters

Like other similar devices, the "Svarog" ARC165 is designed to perform the task of inverting (converting) a DC current to a higher frequency. It was from this function that the name of this welding device went. "Svarog" ARS165 is equipped with two converters of electrical voltage and one electronic microprocessor.

Inverting occurs twice: the current from the mains (eg 220V, frequently - 50Hz) becomes constant at first, and after conversion - variable, but with a lower voltage. The indicators of strength and frequency, on the contrary, increase. The stability of the welding process is ensured by equipping an electronic unit that controls the feedback of the unit with the welding arc. If there is a deviation from the norm, the electronic unit makes an adjustment. The inverter is powered through a common 220V network. With the help of a special stabilizing unit, automatic suppression of possible jumps in voltage occurs.

«Svarog» ARC 165. Description

By using this inverter, it is possible to carry out high-quality manual and argon arc welding. To do this, the owner of the unit must connect to the "Svarog" ARC 165 cylinder with argon and a gas burner. This is possible due to the ability of the inverter to support TIG welding. The owner of this unit can only purchase a valve gas burner and a can of argon. In the production of inverters of this series, the latest technologies are used. The units are equipped with powerful IGBT modular transistors. The inverter is characterized by high performance and reliability.

Performing MMA-welding

Manual arc welding of the inverter is carried out in the range 10-160A. Due to this, the master can work with electrodes, the cross section of which is from 1.6 to 4 mm. Due to the function FORCE, which has an inverter "Svarog" ARC 165 J6501, the adhesion of electrodes in the melt is reduced. The welding arc gets the right power, in order to produce a deep and high-quality welding. This, in turn, positively affects the reliability of the seam and the depth of the melting. Using manual arc welding, it is possible to connect ferrous metals, various grades of steel and alloys.

Welding in TIG mode

The panel of the inverter is equipped with a special tumbler, which allows to work in TIG mode. Before setting the unit to this mode, it must first be connected to a valve burner and a cylinder with argon. In order for tungsten electrodes to wear out less during the ignition of the welding arc, the inverter has a LIFT function. To it resort in various non-standard situations:

• If bad electrodes are used for work.
• If the surface of the product contains rust.
• If the network voltage fluctuations are possible.

The welding unit is adapted for hot start. This function consists in the fact that the inverter is started up when the electrode touches the surface being treated.

TIG mode is mainly used in cases where welding works are carried out with various alloys, low-carbon and stainless steel. Having adjusted the unit to this mode, the master will be more comfortable to control the welding arc. In the process of working in this mode, there is practically no splashing. Stitches, as evidenced by numerous reviews, are much more accurate.

Using IGBT modules

High efficiency of the inverter is achieved due to the presence of powerful IGBT transistors. IGBT modules provide a reduction in energy losses in the unit, even under heavy loads. This inverter can be operated under the most severe conditions. Thanks to the built-in fan, overloads and overheating are not terrible for the Svarog ARC 165 J6501. The owners' testimonies indicate that this unit works quietly enough even with the current set to maximum. The fan effectively cools the power elements, blowing the heated air through special holes in the casing. This makes it possible to use the welding machine in maximum mode for a long time.

VRD mode

The task of this mode is to reduce the voltage automatically in the apparatus running at idle. This positively affects the safety during the operation of the welding machine. Thanks to the VRD mode, the risk of an electric shock is reduced. You can find out more in detail with all the functions and possibilities in the instructions attached to the product "Svarog" ARC 165 J6501.

Application

Invertors "Svarog" ARC 165 Case J6501 are used in the employees of housing and communal services, repair and emergency services. These welding units are very much in demand for the installation of iron structures in construction.

What to consider during operation?

In order for the inverter to last a long time, its owner must follow several recommendations:

• It is desirable to blow the cooling system from time to time, using compressed air. It is especially important to do this in the summer.
• It is not recommended to operate the inverter in closed unventilated rooms. Do not place these welding machines in direct sunlight.
• When operating, consider how the wires are arranged. It is impossible that they bend, break or rub against the inverter housing. Many owners do not pay attention to this during welding. As a result, in some places of the wire there is a loss of contact or places with rubbed insulation, which can be unsafe for the owner.

Conclusion

For those who decided to purchase a welding inverter solely for domestic work, it is best to choose the ARC 165 Case J6501 Svarog. Since in the household welding work is not carried out often, there is no need to purchase expensive professional welding equipment.
