Abstract
There is provided an arc welding control method of alternating feeding of a welding wire between forward feeding and reverse feeding periodically to generate a short-circuiting period and an arc period in a manner that shifting to the arc period is performed by reducing a welding current in the reverse feeding during the short-circuiting period. Reduction of the welding current is started from a time where a state of the reverse feeding reaches a predetermined reference state.
