Abstract
PURPOSE: To prevent the buckling of wire for welding by comparing the current value of a wire feeding motor with a set value in a certain time after a welding current is detected, and then by stopping the feed of wire and welding power source output when the motor current value exceeds the set value.
CONSTITUTION: The flow of a welding current when a welding start instruction signal is sent out is detected as a voltage drop, etc., by a main circuit. Next, its detection signal puts time limit circuit 1 into operation and the output signal generated by time limit circuit 1 a certain time limit later operates comparing circuit 2 as a wire feed state detecting circuit. Circuit 2 compares motor current value IM with set value IA of the motor current that corresponds to a set load. If actual motor current value IM exceeds set value IA, the output signal is sent out to stop the motor, so that while the feed of the wire for welding is stopped, the supply of the welding power source output will also be stopped.
