Power supply MC-250 is made in a single-hulled design and represents itself the inverter power source which is designed for:
- manual arc welding with electrodes (MMA) coated by constant current to direct or reverse polarity.
- welding in all spatial positions.

Welding machine is designed for operation in closed premises with the following conditions:
- ambient temperature from -10C to +40 C;
- relative air humidity no more than 80% at 20 C;
- environment unit, non-explosive, not containing conductive dust, aggressive gases and vapors, that destroy metals and isolation.
