Abstract

ABSTRACT ARC WELDING APPARATUS, ARC WELDING SYSTEM, AND ARC WELDING METHOD An arc welding apparatus includes: a driving unit for advancing and retreating a welding consumable with respect to a workpiece to generate a short circuit condition and an arc condition; a state detecting unit for detecting respective starts of the short circuit condition and the arc condition based on a voltage between the workpiece and the welding consumable; a time detecting unit for detecting that an elapsed time from the start of the short circuit condition reaches a reference time using a time shorter than an estimated continuation time of the short circuit condition as the reference time; and a power control unit for reducing an electric current between the workpiece and the welding consumable corresponding to a state where the elapsed time reaches the reference time and raising the electric current after the start of the arc condition.
