Then, in each period, a mean arc voltage Vav, a pulse voltage Vp, a base voltage Vb, a pulse width Tp, a wire feed rate WF and a certain time T as the length of the period are decided. At this time, at least the welding output control period is divided into two or more periods. Then, the welding is performed based on designated data for the time T.
