FIELD: arc welding with consumable electrode. SUBSTANCE: in process of welding time τ of arc 3 is set depending of short-circuit time tsh.c of arc space 7. Prior to short- circuiting of arc space, arc power is reduced by value ΔP1= (0,4-0,6)Pc, where Pc - power of arc 3 when drop 2 comes in contact with welding pool 6. Arc power in process of short circuit is maintained during time period τ1 which is from 0.7 to 0.9 of short circuit time. By the time of breaking of bridge 8, arc power is reduced by value of 0.2-0.3 of arc power at bridge breaking. EFFECT: enlarged operating capabilities. 4 dwg
