Beschreibung
Zusammenfassung:	An arc welding apparatus (A1, A2) includes a welding-condition acquiring unit (U1) configured to acquire a welding condition; a heat-input calculating unit (U3) configured to calculate a required heat input corresponding to the welding condition; a frequency setting unit (U4) configured to set a smaller frequency for a short circuit condition and an arc condition corresponding to an increase in the required heat input; and a driving unit (41) configured to repeatedly perform a process at the frequency, the process including advancing and retreating a welding consumable (44) with respect to a workpiece (W) to generate the short circuit condition and the arc condition.
