Abstract
An arc welding power supply supplies power to a welding wire functioning as a discharge electrode to generate an arc from an electrode distal end of the welding wire and perform arc welding on a welded article. The arc welding power supply includes an output control unit that adjusts the power supplied to the welding wire to a power value suitable for arc welding. A feed control unit cyclically changes a feeding speed of the welding wire. The feeding speed includes a forward feeding speed and a rearward feeding speed. An amplitude control unit cyclically changes an amplitude of the feeding speed of the welding wire to cyclically vary an average arc length.
