閉要素を設けたアーク溶接機用電源装置。[Claims for Utility Model Registration] An input rectifier that rectifies AC power input through a switch, a capacitor that smoothes the rectified output of the rectifier, and an inrush that flows into the capacitor when power is turned on by the switch. It consists of a resistor that suppresses the current, an inverter that converts the DC rectified and smoothed by the rectifier and the capacitor into AC, and an electrode of an arc welding machine and a base material that rectifies the output of the inverter and converts the rectified output into AC. In a power supply device for an arc welding machine equipped with an output side rectifier that supplies a welding load, a thyristor is provided in parallel with the resistor, and a gate circuit of the thyristor is closed after a delay time after the power is turned on to output a gate signal. A power supply device for an arc welding machine equipped with an opening/closing element that outputs a gate signal and opens when the power is cut off to prohibit the output of a gate signal.
