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.
An arc welding power supply that 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 comprising:
A method for controlling an arc welding power supply that 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 method comprising:
