Zusammenfassung:	FIELD: AC gas-shield welding by means of coated electrodes and non-consumable electrode. ^ SUBSTANCE: apparatus includes single-phase welding transformer, pulse generator, step-up transformer. Primary winding of step-up transformer is connected to outlet of pulse generator. Apparatus also includes discharge capacitor, spark gap, welding load, diode and choke. First terminal of secondary winding of step-up transformer, discharge capacitor and choke is connected with first terminal of secondary winding of single-phase welding transformer. Spark gap is arranged between second terminal of discharge capacitor and second terminal of choke. Second terminal of choke through welding load is connected with second terminal of secondary winding of single-phase welding transformer. Inlet of pulse generator is connected with primary winding of single-phase welding transformer. Diode is connected between second terminal of secondary winding of step-up transformer and second terminal of discharge capacitor. ^ EFFECT: increased value of spark gap and energy of spark discharge at the same power and size of step-up transformer. ^ 3 cl, 1 dwg
