Abstract

PURPOSE: To make starting of welding arc easy, by providing each flowing passage of Ar gas and mixed gas mixed Ar, He, H2 etc. and making changeover of supply gas free at TIG arc welding equipment.
CONSTITUTION: The flow regulator 26 and opening and shutting valve 27, are provided on flowing passage of Ar gas cylinder 25 and also, the flow regulator 22 and the opening and shutting valve 23, are provided on flowing passage of the cylinder 21 of mixed gas mixed Ar and He, Ar and H2 or He and H2. Moreover, the orifice 24 is provided in a row on the circuit of the valve 23 and the above gas flowing passage is connected with the supply opening and shutting valve 28 for welding torch. When welding is started, Ar gas is supplied by shutting the valve 23 and opening the valve 27 and when welding current is turned on, the valve 23 is opened and the valve 27 is shut. Then, TIG arc welding is carried out supplying the above mixed gas. Shape of bead at starting time is regulated by the orifice 24 flowing a part of mixed gas at arc starting time.
