PROBLEM TO BE SOLVED: To solve the problem that the output during a peak current energizing period cannot output a prescribed output voltage, in pulse arc welding.;SOLUTION: In the output control method for the inverter control welding power source for pulse arc welding which subjects consumable electrodes to the pulse arc welding by a welding current consisting of energizing of a peak current and energizing of a base current by using the inverter control welding power source for controlling the output by pulse width modulation control at a prescribed inverter frequency, the inverter frequency is set at the predetermined low frequency during the energizing period of the peak current and is set at the predetermined high frequency during the energizing period of the base current.;COPYRIGHT: (C)2006,JPO&NCIPI
