Among welding inverters , inexpensive, but reliable and unpretentious devices deserve special attention. Among them, the Svarog ARC 205 device can be distinguished from a series of welding units of the same name. Products are made in China.
Advantages and disadvantages
Like many inverters, the Svarog line has the following advantages:
- due to the ease of ignition and a stable arc, which is self-regulating, the welding process is easily mastered even by a beginner;
- little spray is formed and the metal boils well;
- high efficiency - 85%;
- a small open circuit voltage when the inverter is idle is only 9-15 V with recovery to 65 V when the electrode touches the surface;
- the device is protected from overheating, and also the circuit compensates for the voltage drop.
Of the disadvantages, susceptibility to moisture should be noted. In the rain, it is better not to weld or the machine should be reliably protected from splashes. The presence of dust inside the inverters adversely affects their performance. Particularly negatively affected by pollution from cutting or grinding of metal. The devices should be periodically cleaned by blowing with compressed air, preventing the accumulation of dust inside.
Specifications
The Svarog ARC 205 inverter is used in everyday life, but it can often be seen by professionals: in construction, in auto repair shops, etc.
- The welding current is regulated within the range of 10-180 A. Typically, the number on the marking characterizes its maximum value, but this does not apply to some devices of this type.
- Duration of operation (PN) is 60% with an electrode thickness of 4 mm or more. If you take an electrode of 3 mm, then with a current setting of 120-130 A, you can cook continuously (PN = 100%).
- The permissible voltage range is 187-253 V. The device works reliably in rural areas and in suburban areas, where the quality of networks is lower than in the city.
- Weight - 5.8 kg. With the device, you can move around the platform with a belt on the shoulder.
- Welding modes - coated electrode (MMA) and argon arc (TIG - if there are conditions for connecting a valve burner and an argon cylinder to the apparatus). Manual electric welding is performed at any polarity. The current strength is infinitely adjustable. This is not always convenient, as if you accidentally touch it, the setting may go wrong. It is possible through penetration of metal with a thickness of not more than 3 mm.
- 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 its high functionality and good performance justify it.
How much is the welding inverter "Svarog" ARC 205 "? 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. more 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 convenient to use in the private sector, in small workshops and on construction sites.
Machine description
High reliability of welding inverters is ensured through the use of IGBT modules manufactured by the German concern Siemens and designed to work in adverse conditions.
In terms of functionality, the device does not stand out among others. The following functions are used here.
- Hot start - a sharp increase in current when the electrode touches the metal. It does not stick here, which is typical for conventional welding transformers. This is especially noticeable in the process of welding products with layers of rust or with a reduced supply voltage.
- ArcForce is a convenient feature for random arc extinction. There is also a surge of current.
- Antistick - when the electrode sticks, the voltage drops to zero, which prevents a short circuit. The electrode can be torn from the part and the welding process can be continued again.
How to work with the Svarog invertor apparatus?
The durability and reliability of the inverter depends on its proper operation. The device is installed in such a way that sufficient air flow for ventilation is provided to it, dust, dirt, metal sparks do not fall on it and an aggressive environment does not act.
When connecting to the network of the Svarog ARC 205 inverter, you should check its compliance with the characteristics given on the plate attached to the housing. The circuit breaker and socket must match the power of the standard plug of the device. When working in places of contact there should be no arcing and overheating. The device can be used for argon welding.
In manual arc welding, the MMA mode is selected using the switch on the panel.
The forward and reverse cables are tightly inserted into the panel connectors “+” and “-”. Then the tips turn fully clockwise. When welding with direct polarity, the electrode holder is connected to the “-” connector, and the return to “+”.
Excessively long welding cables should be avoided. In order to prevent a large voltage drop on them, long wires should be taken with an increased cross section.
Welding current is set by the handle of the same name. It must match the diameter of the electrode.
Under normal operating conditions, special maintenance on the welding inverter is not required. Particular attention is paid to the reliability of fastening connectors and the absence of damage to power cables, the housing and controls.
Frequent malfunctions and their elimination
The welding inverter "Svarog ARC 205" is characterized by the problems inherent in all similar models.
- Protection trips due to overheating. The reason may be dusting 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 fails, although the device does not overheat. The part should be replaced in the service. There may be poor contacts at the joints, which should be tightened.
- Constant sticking of the electrode and low quality of the arc with a serviceable apparatus occur when the voltage in the network drops below normal or when using weak power wires.
- The burnout of the apparatus with the smell of burning insulation occurs as a result of a short circuit. Repair is carried out in specialized workshops. Blown wires can be replaced on their own.
Annual maintenance of the device in the service center allows you to use it much longer than the warranty period of 5 years. For different manufacturers, it can differ and amount to no more than 2 years, although this is not so small.
