源装置。[Claims for Utility Model Registration] A rectifier circuit that converts an alternating current power source into direct current, a high frequency conversion circuit that converts the DC voltage to high frequency, and two secondary windings each having an intermediate tap on both sides. A full-wave rectifier circuit including a transformer that transforms the high-frequency voltage, and diodes connected to terminals at both ends of the two secondary windings, and these two.
It consists of an open/close circuit that applies the rectified outputs of the two rectifier circuits to the base metal and the welding electrode alternately with positive polarity and reverse polarity, respectively, and converts the transformed high frequency into a low frequency and applies it to the base metal and the welding electrode. A low frequency conversion circuit, a high frequency conversion circuit control section that controls the high frequency conversion circuit, a switching circuit control section that controls the switching circuit, and turning on/off the operation of the high frequency conversion circuit control section and the switching circuit control section. An electrode source device for alternating current arc welding having a starting switch, characterized in that the electrode source device for alternating current arc welding is provided with operation holding means for maintaining the on state of the switching circuit control section for a certain period of time after the starting switch is turned off. power supply.
