Abstract

PURPOSE: To improve the operation efficiency by making the time limit up to the feed of a wire for welding and the stop of an output voltage by a detection signal earlier than normal welding completion, by detecting the buckling of a wire during welding operation.
CONSTITUTION: On the completion of normal welding, wire feed stop instruction signal source 1 stops the feed of a wire for welding simultaneously with the inputting of a torch switch signal. Then, time limit circuit 3 stops the supply of an output voltage through output voltage stop instruction signal source 2 a certain time later. On the other hand, a wire buckling prevention device operates during the welding operation to input an operation signal and at the same time, wire feed stop instruction signal source 1 operates to stop the feed of the wire for welding. Then, time limit circuit 4 stops the supply of the output voltage through output voltage stop instruction signal source 2 a certain time later. The delay time of this time limit circuit 4 is shorter than that of time limit circuit 3, so that the feed of the wire and the supply of the voltage will be stopped earlier than normal welding completion.
