Abstract

PURPOSE:To reduce spatters and to obtain a welded zone with the high quality by controlling the welding output via an output control circuit part based on an arc short-circuit decision signal obtained by comparing the output voltage and a welding current detected with reference criterion values and calculating the compared values. CONSTITUTION:A comparison reference signal which is obtained by inputting the welding current detected with a welding current detection circuit part 13 to a comparison reference signal selector circuit part 14 and an output voltage detection signal detected from an output voltage detection circuit part 13 are inputted to an arc short-circuit decision circuit part 15. The arc short-circuit signal obtained based on both signals is inputted to the output control circuit part 16 to control the welding output. By such constitution, the welding output is controlled at the real time and the welding with the high quality is performed.
