FIELD: process engineering.
SUBSTANCE: invention relates to short-arc welding. At short-circuit origination 30, time interval 32 is set whereat definite current characteristic is generated for interruption of short circuit 30 thereat. In case said time interval 32 is too large current is increased. At the end of said time interval during short circuit, said current characteristic is registered for interruption of short-circuit to memorise, hence to store, at least one magnitude, hence one parameter at short-circuit interruption. At least one magnitude, hence one parameter is brought into correspondence with stored magnitude, hence parameter in said time interval.
EFFECT: stable welding process, higher quality.
