FIELD: electrical engineering.
SUBSTANCE: invention relates to plant (100) for welding and grinding wire. The plant contains welding machine (112) for wire, AC electric engine (114) for actuating grinding machine (116), and AC power source (110) for welding machine (112) and AC electric engine (114). Smooth start module (118) is designed to reduce starting current for AC electric engine (114) at start.
EFFECT: use of smooth start module (118) allows for using battery (102) as a power source, and the use of the battery as the power source has an advantage of practical plant mobility and obtaining stable welding currents.
