ABSTRACT:
An arc welding control method for repeating alternately a short circuit period allowing a welding wire to short circuit with respect to a member to be welded and an arc period allowing arc recurrence and arc discharge to thereby weld the member to be welded, in which a welding output current just after arc recurrence is controlled to be higher than a welding output current just before arc recurrence for a set given period.
