FIELD: electrical engineering, equipment for AC arc welding. SUBSTANCE: welding transformer has bar magnetic core, primary winding put on first bar and secondary winding arranged on second bar which has section amounting to 0.5-0.8 section of first bar. Secondary winding is saturated when transformer operates under no-load condition. Capacitor compensating reactive component of current consumed by transformer may be placed between leads of primary winding. EFFECT: reduced mass of welding transformer. 2 cl, 1 dwg
