FIELD: mechanical engineering; welding equipment. SUBSTANCE: proposed welding arc supply source has alternating voltage source, compensating capacitor, filtering device, arc relay and additional compensating capacitor. One of terminals of normally closed contacts of arc relay is connected to one of terminals of supply circuit. Other terminal of relay contacts is connected to one of terminals of additional compensating capacitor. Second terminal of additional compensating capacitor is connected to second terminal of supply circuit. EFFECT: enlarged operating capabilities. 1 dwg
