Among welding inverters, inexpensive, but reliable and unpretentious devices deserve special attention. Among them, we can distinguish the device "Svarog ARC 205" from a series of welding units with the same name. Products are made in China.

Pros and cons

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

• due to the ease of ignition and a stable arc that is self-adjusting, the welding process is easy to master even for a beginner;
• little spatter and good weldability;
• high efficiency - 85%;
• small open-circuit voltage when the inverter is not working is only 9-15 V, recovering to 65 V when the electrode touches the surface;
• the device is protected from overheating, and the network voltage drop is also compensated in the circuit.

Of the shortcomings, susceptibility to moisture should be noted. In the rain, it is better not to weld, or the device should be reliably protected from splashes. Availabilitydust inside inverters adversely affects their performance. Dirt from cutting or grinding metal is especially negatively affected. The apparatus should be periodically cleaned by blowing with compressed air to prevent dust from accumulating inside.

Specifications

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

1. The welding current is adjustable within 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. Duration of work (PN) is 60% with an electrode thickness of 4 mm. If you take the electrode at 3 mm, then with a current setting of 120-130 A, you can cook continuously (PN=100%).
3. The allowable supply voltage range is 187-253 V. The device works reliably in rural areas and summer cottages, where the quality of networks is lower than in the city.
4. Weight - 5.8 kg. The machine can be moved around the job site with a shoulder strap.
5. Welding modes - coated electrode (MMA) and argon-arc (TIG - if there are conditions for connecting a valve burner and a cylinder with argon to the machine). Manual electric welding is performed with any polarity. The current strength is infinitely adjustable. This is not always convenient, because if accidentally touched, the setting may go astray. Through penetration of metal with a thickness of not more than 3 mm is possible.
6. The diameter of the electrodes can be changed from 1.6 to 4 mm. For high currents, the wiring must comply withpower, and the machine is used for a current of at least 16 A.

Welding inverter "Svarog ARC 205": price

For the price of its class, the device may seem expensive, but its high functionality and good performance justify it.

How much does the welding inverter "Svarog "ARC 205" cost? The price is about 14 thousand rubles. When buying, 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) - for 180 A. If the first one can be welded with an electrode up to 5 mm, then the second fits a maximum of 4 mm.

Inverter with display

The model costs 2 thousand rubles. expensive. The model is made in a modern style, with small dimensions, has high reliability. The presence of a built-in fan helps prevent overheating of the device. The device is suitable for use in the private sector, in small workshops and on construction sites.

Description of the machine

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 the metal. It does not stick here, which is typical for ordinarywelding transformers. This is especially noticeable when welding products with layers of rust or at reduced supply voltage.
2. ArcForce is a handy feature in case of accidental extinguishing of the arc. There is also a current surge here.
3. Antistick - when the electrode sticks, the voltage drops to zero, which prevents a short circuit. The electrode can be removed from the workpiece and the welding process can be continued again.

How to work with inverter apparatus "Svarog"?

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

When connecting the Svarog ARC 205 inverter to the network, 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 the contact points, there should be no sparking and overheating. The machine can be used for argon welding.

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

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

Excessively long welding cables should be avoided. Not toallow a large voltage drop on 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 the fastening of the connectors and the absence of damage to the power cables, housing and controls.

Frequent faults and troubleshooting

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

1. Protection shutdown due to overheating. The cause may be dust on the device. The inverter should be periodically or selectively cleaned by blowing with compressed air. Dust accumulates during continuous use on open construction sites. When the thermal relay fails, it falsely trips, although the device does not overheat. The part should be replaced in the service. There may be bad contacts at the connections, which should 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. 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 wires can be replaced by yourself.

Annual maintenance of the machine inservice center allows you to operate it much longer than the warranty period of 5 years. For different manufacturers, it may differ and be no more than 2 years, although this is not so little.

Inverter "Svarog ARC 205": reviews

According to users, the device does not overheat when used properly. Unlike other products, "Svarog ARC 205" works stably at ambient temperatures up to +40°С.

There is a wide range of mains voltage, which allows the device to be used in the country. A stable arc is maintained at a voltage of 160 V. Especially beginners like the device, helping them in their work at the initial stage of training. Experienced welders note the convenient configuration of the device in one suitcase, where the shield, cables and holder are placed along with the device.

When working in wet weather, it is recommended to protect the welding machine "Svarog ARC 205" from splashes.

In frosty weather, you can cook at a temperature not lower than -10 ° C, because the electronics can not stand it further.

The company confirms the high performance of the device, giving it a long-term warranty.

Conclusion

The device "Svarog ARC 205" is mostly designed for professional work or for large amounts of work in everyday life. For occasional occasional use, you can purchase a cheaper and simpler model with fewer features.
