Abstract

PURPOSE: To obtain stable arc and obtain current and voltage waveform of less output ripple in the case of direct arc welding by performing arc welding with the power supply having frequencies higher than commerical frequencies.
CONSTITUTION: Comparison of the output signal from a shant Sh and the preset signal is accomplished in the A part and thyristors S1WS3 are controlled by using ordinary electrical means. Thereby, the voltage regulation of a capacitor C1 is performed and inverter input is increase-or decrease-controlled. In this way, the capacitor C1 portion is made as a correct DC voltage source which takes the inverter of the rear stage into account and further a select switch SW of AC arc and DC arc is used for the output side of a transformer T. Although this power supply for arc welding can be connected to the power supply equipment of commerical frequencies, its output frequency may be varied and in the case of DC arc, the output characteristics of extremely less ripples are obtainable, hence it makes a large contribution to the stability of welding arc.
