Abstract

PURPOSE: To obtain the output having both characteristics of constant voltage and suspension in one welding machine, by connecting the autotransformer having output variable mechanism and series circuit with turn-over switch in series, at the power source apparatus for arc welding machine.
CONSTITUTION: In order to obtain necessary voltage for welding, primary winding of the autotransformer 2 having the output variable mechanism 3 in parallel with the secondary winding of the insulating transformer 1 and series circuit with the turn-over switch 4, are connected in parallel. When the switch 4 is made On at the a side, the autotransformer is turned to the constant voltage transformer and output voltage is made variable by the mechanism 3. On the one hand, the switch 4 is made OFF at the a side, the autotransformer 2 is operated as alternating current reactor and output having suspension characteristics, is able to obtain. By the above construction, stable arc welding is able to carry out at a single phase power source also.
