Abstract

PURPOSE: To obtain an AC-DC arc welding machine of electric power saving type by connecting the 1st and 2nd thyristors for output controlling to the primary side of a welding transformer.
CONSTITUTION: The antiparallel circuit of the 1st and 2nd unidirectional control rectifier elements connected in series with the 1st, and reactors 11a, b wound at the same number of turns on the same cores in such a way as to make the directions of magnetic fluxes the same is inserted and connected between the primary winding 10a of a welding transformer 10 of a single phase wherein the secondary windings 10b, c connecting to a welding load 16 are bisected at the same number of turns, and an electric power source. Selecting means 13a, b, c for AC output and DC output are inserted and connected between the secondary windings 10b, c of the transformer 10 and the welding load 16, and the secondary windings 10b, c are connected in parallel so as to attain the same polarity in the case of obtaining the AC output with the means 13 and the secondary windings 10b, c are connected in series so as to attain an additive polarity in the case of obtaining the DC output, whereby the AC and DC outputs are supplied to the welding load 16 via a rectifier circuit 14 and a DC reactor 15 for smoothing.
