Zusammenfassung:	PURPOSE:To obtain high efficiency without the influence of magnetic blow by constituting the welding power source with the power source for arc which arranges switching element in parallel with the arc and the wire heating power source arranging the switching element in series with a hot wire. CONSTITUTION:A GTO 9 is connected in parallel with an arc 5 against the output of the constant current power source which can vary the set current on TIG power source 1. A circuit 21 is formed so as to form pulse arc current by turning it ON-OFF periodically. On the other hand a circuit 22 is made by connecting GTO 10 so as to form pulse arc current by turning it ON-OFF periodically. On the other hand a circuit 22 is made by connecting GTO 10 so as to become in series with a wire 6 against the output of the constant voltage power source which can vary the set voltage on a wire heating power source 2. It is then constituted so as to electrify and heat the wire periodically for the term when the arc current becomes lower by connecting both circuits via a base metal 8.
