PROBLEM TO BE SOLVED: To provide a narrow weld joint TIG welding machine, which can improve productivity and can reduce a production cost.;SOLUTION: In the narrow weld joint TIG welding machine which performs welding for joining metals having a narrow weld joint, an electrode does not have a conical shape but has an eccentric shape, and the eccentric electrode melts wires while turning in the narrow weld joint. In addition, in the narrow weld joint TIG welding machine, the wires are supplied from the front and the rear of the eccentric electrode. In addition, in these two wires, the wire supplied from the front of the eccentric electrode is supplied after heating, and the wire supplied from the rear of the eccentric electrode is supplied without being preheated. Further, both of the wires supplied from the front of the eccentric electrode and the wire supplied from the rear of the eccentric electrode are supplied after heating.;COPYRIGHT: (C)2004,JPO&NCIPI
