Abstract

PURPOSE: To reduce the ripples of pulse current and reduce the arc sound during welding by controlling the 2nd switch group to on in the period when the 1st switch group regulating the electricity conduction period of the pulse current is off.
CONSTITUTION: First, the 1st switch group is turned on and when the pulse current detected with a shant 20 attains a prescribed value, the 1st switch group goes off; at the same time, the 2nd switch group goes on. Then, IB rises, and IA attenuates upon releasing of the energy accumulated directly in a reactor 12. When this pulse current attains a prescribed value, the 1st switch group goes on, and the 2nd switch group off. Thereafter, when the on and off of both switch group are repeated in the pulse period, pulse current I is the cmposite of IA and IB, and the repples of the pulse current I are reduced.
