ABSTRACT:
A wire feeding speed is decreased to a level lower than a base wire feeding speed in a short-circuiting period, and set to the base wire feeding speed in an arcing period. During the arcing period, a welding current is increased to a predetermined peak value by means of current control from the start of arcing to a first predetermined time, the welding current is then supplied with a welding voltage, a source voltage of which is controlled constant, from the first predetermined time to a second predetermined time, and the welding current is decreased to a predetermined base current by means of current control from the second predetermined time until the end of the arcing period.
