Advantages and disadvantages

Like many inverters, the Svarog line has the following advantages:

• due to the ease of ignition and a stable arc that self-regulates, even a beginner can easily master the welding process;
• little splashes are formed and the metal is well boiled;
• high efficiency – 85%;
• a small open-circuit voltage when the inverter is not working is only 9-15 V with recovery to 65 V when the electrode touches the surface;
• The device is protected from overheating, and the circuit also compensates for differences in mains voltage.

Among the disadvantages, susceptibility to moisture should be noted. It is better not to weld in the rain, or the machine should be reliably protected from splashes. The presence of dust inside inverters adversely affects their performance. Contamination from cutting or grinding metal has a particularly negative impact. The devices should be periodically cleaned by blowing with compressed air to prevent the accumulation of dust inside.

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.

Specifications

The Svarog ARC 205 inverter is used in everyday life, but it can often be seen among professionals: in construction, in car repair shops, etc.

1. The welding current is adjustable within the range of 10-180 A. Usually the number on the marking characterizes its maximum value, but this does not apply to some devices of this type.
2. The operating time (DU) is 60% with an electrode thickness of 4 mm. If you take a 3 mm electrode, then with a current setting of 120-130 A you can cook continuously (PN = 100%).
3. The permissible supply voltage range is 187-253 V. The device works reliably in rural areas and in summer cottages, where the quality of networks is lower than in the city.
4. Weight – 5.8 kg. You can move the device around the work site with a strap on your shoulder.
5. Welding modes - coated electrode (MMA) and argon arc (TIG - if there are conditions for connecting a valve torch and an argon cylinder to the machine). Manual electric welding is carried out in any polarity. The current strength is infinitely adjustable. This is not always convenient, since the setting may be lost if accidentally touched. Through penetration of metal with a thickness of no more than 3 mm is possible.
6. The diameter of the electrodes can be changed from 1.6 to 4 mm. At high currents, the wiring must correspond to the power, and the machine is used for a current of at least 16 A.

Welding inverter "Svarog ARC 205": price

At the price of its class, the device may seem expensive, but it is justified by its high functionality and good performance.

How much does the Svarog ARC 205 welding inverter cost? The price is about 14 thousand rubles. When purchasing, you should pay attention to the characteristics. For example, “Svarog TECH ARC 205 B” (Z203) is designed for a maximum welding current of 200 A (power - 9 kVA), and “Svarog ARC 205” (J96) is designed for 180 A. If the first one can weld with an electrode up to 5 mm, then the second fits a maximum of 4 mm.

Description of the device

High reliability of welding inverters is ensured through the use of IGBT modules manufactured by the German concern Siemens and designed to operate in adverse conditions.

In terms of functionality, the device does not particularly stand out among others. The following functions are used here.

1. Hot start - a sharp increase in current when the electrode touches metal. It does not stick here, which is typical for conventional welding transformers. This is especially noticeable during welding of products with layers of rust or at low supply voltage.
2. ArcForce is a convenient feature for accidental arc extinguishing. A surge of current also occurs here.
3. Antistick – when the electrode sticks, the voltage drops to zero, which prevents a short circuit. The electrode can be torn off the part and the welding process can be continued again.

Inverter circuit for welding

The circuit of the inverter welding unit has a special characteristic and functionality, which includes the following components:

• Control and indication body.
• System responsible for operating the thermal protection function and controlling the cooling fan. This also includes the fan of the inverter itself and a sensor with temperature indicators.
• Electrical circuit diagrams imply the presence of a PWM controller, consisting of a transformer with current, a sensor with load current.
• Power supply system for the low-current part of the electrical circuit of a hardware inverter for welding.
• A mechanism can be installed in the circuit converter, thanks to which power is supplied to the power system of the device. This includes a capacitive filter, a rectifier, and a nonlinear charging circuit.
• Power section with single-cycle converter. It also includes: a power transformer, a secondary rectifier and a choke for the current output.

Each description of the circuit diagram of a welding inverter should contain a brief description of all the constituent elements.

How to work with the Svarog inverter device?

The durability and reliability of the inverter depends on its proper operation. The device is installed in such a way that it is provided with sufficient air flow for ventilation, and is not exposed to dust, dirt, metal sparks, or exposed to an aggressive environment.

When connecting the Svarog ARC 205 inverter to the network, you should check its compliance with the characteristics given on the plate attached to the case. The circuit breaker and socket must match the power of the standard plug of the device. When working at contact points there should be no sparking or overheating. The device can be used for argon welding.

When manual arc welding, MMA mode is selected using a switch on the panel.

The forward and return cables are tightly inserted into the panel connectors “+” and “-”. Then the tips are turned clockwise all the way. When welding with straight polarity, the electric holder is connected to the “-” connector, and the return line is connected to “+”.

Excessively long welding cables should be avoided. To prevent a large voltage drop across them, long wires should be taken with an increased cross-section.

The welding current is set by the control knob of the same name. It must match the diameter of the electrode.

Under normal operating conditions, special maintenance of the welding inverter is not required. Particular attention is paid to the reliability of connector fastening and the absence of damage to power cables, housing and controls.

Frequent malfunctions and their elimination

The welding inverter “Svarog ARC 205” is characterized by problems inherent in all similar models.

1. Protection shutdown due to overheating. The reason may be dust on the device. The inverter should be cleaned periodically or selectively by blowing with compressed air. Dust accumulates with constant use on open construction sites. If the thermal relay fails, it triggers falsely, although the device does not overheat. The part should be replaced by a service center. There may be bad contacts at the connection points that need to be tightened.
2. Constant sticking of the electrode and poor quality of the arc with a working device occur when the voltage in the network drops below normal or when weak power wires are used.
3. The burnout of the device with the smell of burning insulation occurs as a result of a short circuit. Repairs are carried out in specialized workshops. Burnt out wires can be replaced yourself.

Annual maintenance of the device at the service center allows you to operate it significantly longer than the warranty period of 5 years. It may differ from one manufacturer to another and may not exceed 2 years, although this is not too short.

What you need to know to use your inverter effectively

The inverter machine Svarog ARC model 205 is equipped with convenient controls and monitoring devices, which makes it possible for even a novice specialist to carry out welding effectively. Thus, the device controls allow you to select the required welding current, the type of welding to be performed (MMA or TIG), enable a function that allows you to reduce the open circuit voltage, and connect a remote control to the equipment.

A digital ammeter located on the front panel of the device allows you to control how much current is currently used for welding and quickly select its required value. Before you start working on this device, you should carefully study the instructions for it, read the reviews and recommendations of experienced specialists.

The quality of welding, even if it is performed using serviceable equipment, can deteriorate significantly if there is rust, paint coatings, scale, oxide film and various contaminants on the surface of the parts being joined. That is why, if you need a high-quality, reliable and neat weld, the surfaces of the parts to be joined must be thoroughly cleaned.

The condition of the electrodes used also has a serious impact on the quality of the formed weld. If the electrodes were stored in conditions of high humidity and their coating became damp, they are calcined in an oven and only then used for their intended purpose.

When welding using an inverter, it is not recommended to tap the electrode on the surface of the parts to ignite the arc. This can cause the coating to peel away from the metal core. It is enough to scratch the tip of the electrode on the surface of the part to ignite the welding arc.

Approximate machine settings for TIG welding of stainless steel sheets

If you use a non-consumable electrode using TIG technology, it is necessary to regularly update its sharpening, as well as monitor such a parameter as the electrode stickout, which is measured in relation to the end of the welding torch nozzle.
