Abstract

PURPOSE: To eliminate the play of a wire in a conduit tube and prevent the delay in feeding the wire at the next welding by stopping feeding the wire then running a wire feed motor backward and forward to set the welding wire in the correct position.
CONSTITUTION: The normally open contacts 25 of arc generation detection signal and the normally open contacts 27 of wire feed start signal are closed, by which a relay 22 is energized to close the normally open contacts 22a, thereby running forward a wire feed motor 21 and feeding the welding wire to the weld zone. Next, when the welding torch is detached from the base metal and the arc is cut, the contacts 25 which had closed open to de-energize the relay 22 and open the contacts 22a thereby stopping running of the motor 21. On the other hand, the normally open contacts 26A are closed by opening of the contacts 22a to keep the relay 2b latched on and further the normally closed contacts 22b are closed to energize the relay 23 and time-limit relay 28. As a result of this, the normally open contacts 23a are closed to run the motor 21 backward and return the welding wire. Next, the motor 21 is run forward by the similar operations and is further stopped, at the same instant of which a sequence circuit is reset.
