Abstract

PURPOSE: To reduce electric power consumption and suppress the production of noise by operating a control device to make switching operation by switching elements when a short circuit detector or welding voltage detector operates.
CONSTITUTION: A control device CO commanding the switching operations of switching elements Q1, Q2, short circuit detector DS supplying the auxiliary DC output of the voltage lower than that of the main DC output to a welding load WL and operating by detecting short circuiting of the welding load with an electrode TD and base metals M, and a welding voltage detector DV detecting the welding load lower than the main DC voltage and hihger than the auxiliary DC output voltage are provided. Thereupon, when the detector DS or the detector DV operates, the device CO operates to make switching operation by the elements Q1, Q2.
