Abstract

PURPOSE: To improve the performance of welding machine by adjusting the output of welding power source when the counted value coincides with the ignition time, by operating the ignition time from the detected value of welding power source and its set value and, at the same time, by counting the timing pulse.
CONSTITUTION: Comparator CMP3 compares the voltage of voltage adjusting variable resistor VR2 and the output of arc voltage detector VD, and outputs its signal CES to interface 110. Arithmetic device CPU increases or reduces the SCR ignition phase angle data of arc voltage feedback circuit 20 by unit amount in accordance with signal CES at every zero-cross of detecting circuit 18, and stroes them in memory RAM. When the counted value of timer pulse signal TPS coincides with the data of memory RAM, gate signal GPS2 is outputted to SCR3 for voltage by arithmetic device CPU.
