Abstract
There is provided an arc welding power supply. An output control unit outputs welding voltage and current in correspondence to each of a short-circuiting period and an arc period. A feeding control unit controls a feeding rate of a welding wire. A short-circuit forcibly generating period is provided between forward feeding acceleration and deceleration periods. In the short-circuit forcibly generating period, the feeding control unit increases the feeding rate with a change rate larger than a change rate during the forward feeding acceleration period and maintains a predetermined forward feeding peak value when the feeding rate reaches the peak value.
