What makes the welding inverter SVAROG ARC 205 (J96) stand out?

The main difference between Svarog machines with the letter index “J” is their versatility; in this case, the ARC 205 (J96) machine is distinguished by the possibility of using it for two types of DC welding: for manual arc welding with coated electrodes (MMA/RD), and also for manual argon arc (TIG/RAD).

The device has one of the most modern technological fillings, which is why it is light in weight and size, has high efficiency and is able to withstand heavy loads for a long time.

The maximum welding current of this machine is 185 A, which means that the machine can be used for welding with coated electrodes with a diameter of 4 mm, and with manual argon arc welding the maximum penetration depth can reach up to 3 mm. The polarity when welding is easily changed by switching the cables from one terminal to another.

The device has built-in additional functions “HOTSTART” and “Lift”, which are designed to facilitate the ignition of the arc and the start of welding.

Another remarkable characteristic of this product is its excellent price-quality ratio. At a low cost, it fully satisfies the basic requirements for high-quality and safe welding both for personal needs and for larger and more serious production projects, small auto repair shops, etc.

The ARC 205 welding machine, based on a modern inverter circuit, is designed for manual arc welding (MMA) and surfacing with a coated stick electrode on direct current of low-carbon steel products in industrial and domestic conditions. And when a valve TIG torch and an argon cylinder are connected to the machine, argon arc welding is possible.

The device is manufactured on the basis of modern inverter technology using powerful IGBT transistors using the principle of pulse width modulation (PWM). It features stable, reliable, long-lasting and efficient operation, portability and low noise during welding. Features of the ARC 205 device are high efficiency, low energy consumption, mobility, stable arc combustion, low open circuit voltage, self-regulation of arc power. As well as high ergonomics, modern design, ease of control.

How it works in practice

SVAROG ARC 205 (J96) is a model that never overheats and functions until the electrode burns out. This does not depend on the time of year, air temperature or metal thickness. It is almost impossible to spoil this device: according to the passport, the PV is 60%, and during testing it shows up to 80%. You don't have to wait for the inverter to cool down, as happens with its household counterparts. The power of the device is enough to weld metal 6mm thick. Rest assured, this is enough for household and installation work. In addition, such an inverter not only cooks, but also easily cuts metal.

The inverter can be used in any premises where there is a relatively free flow of fresh air, as well as in open areas in temperate climates (humidity - up to 80 percent, ambient temperature - no more than +40 degrees). When using it as part of mobile repair complexes, it is necessary to make sure that the technical parameters of these complexes and the welding installation are fully compatible with each other.

The protective category of the welding equipment in question does not allow its operation during precipitation. It's always worth remembering this.

The unit must be installed on a flat surface, and in such a way that it is provided with sufficient ventilation (without constant natural cooling of the equipment, it will very quickly fail). Dirt, particles of molten metal, and sparks are not allowed to enter the installation.

The inverter is connected to a regular power outlet, which is equipped (mandatory) with an auto-fuse. It is important to ensure tight contact of the unit plug with the socket, which will eliminate the risk of sparks during welding and surfacing. It is advisable to always use the original network cable to connect the device.

The return and forward cables for electric arc welding (MMA process) are connected to the corresponding connectors on the front side of the inverter, and then turned all the way in the clockwise direction. You need to ensure that the cables are connected as tightly as possible, otherwise there is a risk of damage to the power source and the cable connector itself.

If you plan to work with reverse polarity, connect the electrical holder (according to the rules stated above) to the “positive” connector, and the return cable to the “negative” connector. When working on straight polarity, the return cable is connected to the “plus”, and the holder is connected to the “minus”. The choice of a specific connection option depends on what welding rod you plan to use (its thickness can be from 2 to 5 millimeters), as well as on certain welding features.

To operate the inverter installation, which is the subject of this article, in TIG mode, you need to purchase a special connection set and a valve-type torch. The power tip of the burner connector is connected to the “minus”, turned and tightly fixed. The return cable is connected to the “plus”, and then the grounding clamp is fixed to the workpiece. The welding installation must be grounded. This will eliminate current leakage and the possibility of static electricity.

Gas for welding is supplied to the machine through a gas supply system, which includes:

• a cylinder filled with gas;
• gas hose (its connections should be as tight as possible);
• gearbox

Since the J96 model does not have an oscillator, the arc in TIG welding is ignited by touching.

Application area of ​​the inverter

The device is packed in a stylish case, allowing you to carry both the device itself and all the necessary accessories, as well as protective equipment. A set of additional functions ensures comfortable work for the welder on site. The outer shell with protection level IP 21 protects the device from foreign objects and drops of water falling vertically onto the housing.

The inverter is suitable for welding in private households, garages or small car repair shops. It is indispensable when carrying out construction and installation work of any volume associated with visiting the site, and is applicable in the housing and communal services sector. The device is convenient to use as part of the equipment of mobile emergency services complexes, in small-scale production. Low weight and dimensions allow welding in hard-to-reach places when repairing metal structures.

Welding with the Svarog ARC 205 inverter is carried out with direct current (DC) using inverter technology. The device is powered from a conventional single-phase network 220 V, 50 Hz. In the absence of a stationary power source, it is possible to connect to a gasoline or diesel generator that provides voltage in the range of 185 V–260 V.

The AC supply voltage is converted into DC by the mains rectifier and inductor. The resulting direct current is supplied to the IGBT block of power bipolar transistors. It inverts direct current into RF alternating current with a frequency of 20–50 kHz. The step-down transformer reduces the voltage to the operating level, after which it is rectified again and supplied to the operating connectors located on the front panel of the case.

Such preliminary conversion to high-frequency current allows the use of a transformer with very small dimensions. Compared to “classic” welding machines, the inverter weighs several times less, has better technical characteristics and efficiency.

The high quality of the welding process is ensured by a control unit with digital signal conversion (DSP).

Rules for using equipment

Like most inverters, Svarog ARC 205 (J96) is not recommended for use in conditions of precipitation, as evidenced by its protection class - IP 21S. Select a flat area for the installation location of this device. The inverter housing should not be cluttered with foreign objects. If you do not provide natural ventilation to the device, it will quickly fail. It is necessary to ensure that sparks, particles of molten metal and dirt do not fall on the equipment body.

When connecting the inverter to the electrical network (a socket with an automatic fuse is used for this), it is necessary to ensure the tightness and reliability of the contacts in order to avoid their sparking and intense heating during the welding process. To avoid problems when operating the welding inverter, it is best to use the original power cable to connect it.

Typical inverter malfunctions and methods for eliminating them

The cables through which electric current is supplied to the welding holder and ground are connected to the corresponding connectors on the front of the device. The contact tips of the electrical cables are inserted into such connectors and turned clockwise until they stop. In this case, it is necessary to ensure that the contact is tight and reliable. Then during welding there will be no sparking, heating in the links of the electrical circuit and voltage losses.

As is known, welding, depending on its characteristics and the type of electrode used, can be performed with direct or reverse polarity. In the first case, a cable going to ground is connected to the positive connector on the inverter, and a cable with a welding holder is connected to the negative connector. To perform welding with reverse polarity, respectively, the cable of the welding holder is connected to the positive connector, and the ground wire is connected to the negative connector.

To avoid significant voltage losses in welding wires, inverter manufacturers make them quite short, about 2.5 meters. If there is a need to use longer wires, you will need a cable with a larger cross-section. Then the voltage losses will not be too critical.

Packaging and appearance of the welding machine

As mentioned above, the Svarog ARC 205 welding inverter is also used for welding in a shielding gas environment (TIG). To practically implement this technology, it is necessary to additionally purchase a valve-type burner and a special connecting set for the inverter apparatus. Using a connecting set, the burner is connected to the negative connector of the inverter, and a ground cable is connected to the positive connector, the reverse end of which is fixed to the parts being welded using a clamp. Before starting welding work, the housing of the inverter device must be grounded. This will ensure welding safety and eliminate the risk of static electricity.

When performing TIG welding, shielding gas must be constantly supplied to the work area, which is provided through a gas supply system that includes:

• gas cylinder;
• a hose through which gas is supplied to the welding zone;
• a reducer with which the pressure of the supplied gas is regulated.

Welding set for argon welding

The design of the inverter of the model under consideration does not have an oscillator that provides non-contact ignition of the welding arc, therefore, when performing TIG welding, the arc must be ignited by touching the surface of the parts being joined with the electrode.

Key features of the device

• the presence of the Hot Start function (hot start) when igniting the electric arc;
• equipped with Antistick anti-stick option;
• adjusting the arc force (increasing power) guarantees deep penetration and a flat, even seam even at low current;
• 80% load duration when operating at a maximum current of 180 A;
• the ability to connect to a container with argon with subsequent welding of “non-ferrous metal” with non-consumable electrodes using the TIG method;
• equipped with a fan, protection against overheating and overvoltage of a single-phase 220 V network;
• the presence of a switchable idle voltage reduction system VRD.

Advantages and disadvantages of the ARC 205 model

The inverter has the following advantages:

• the weld seam, subject to the minimum rules, is laid evenly and is always deeply welded;
• Electrodes with any type of coating can be used as consumables;
• possibility of connecting a TIG torch for welding in argon;
• presence of forced cooling with a built-in fan.

The disadvantages of this model include:

• lack of push-button activation/disabling of the “hot start” and “anti-stick” functions (automatic only);
• activation of the overheating protection system, which turns off the device for a few minutes during continuous hours of operation;
• The inverter shell does not protect against dust, dirt particles and side drops of rain from entering the device, in this it is inferior to models from other manufacturers presented on the Russian market.

Customer Reviews

According to customer reviews, the ARC 205 welding inverter model can be considered one of the best in its class. With its help, you can perform work of varying complexity and volume. However, for confident welding with “five” electrodes, the maximum current of 180 A is not enough.

The model is equipped with a handle (and not just a strap) for carrying, which creates additional convenience for users. The display quite accurately reflects the actual current of the inverter; the spread of the parameter is ±3–4 Amperes. According to users, the peculiarity of this device is that it does not overheat and operates stably at ambient temperatures up to +40ºС. The use of toggle switches on the front panel in real operating conditions is more justified than “pressable” pseudo-sensors.

The manufacturer recommends operating this inverter not only in rooms with a free flow of fresh air, but also in open areas (if they are located in a temperate climate zone: ambient temperature no more than 40 degrees, relative humidity no higher than 80%). If the welding machine will be connected to autonomous sources of electric current, you should check that their characteristics are compatible.

Advanced patented technologies were used in the development and creation of the Svarog ARC 205 inverter. The quality of the welding process, which is carried out using such equipment, is monitored by a control unit operating using digital signal processing (DSP) technology. The basis of such a unit is a special chipset produced by the famous company Atmel.

The inverter unit, which is responsible for generating high-frequency current pulses, is assembled on the basis of power transistors manufactured by Toshiba (MOSFET) and Siemens (IGBT).

The electrode holder included in the package is very convenient and of good quality.

Reviews of inverters of a similar category from other manufacturers indicate that the Svarog brand device is not the best in its class. However, if you take into account the cost, dimensions, weight and decent technical characteristics of the inverter of this model, it deserves the attention of specialists.
