        Model:WSM 315/400/500Inverted DC pulse argon arc welding machine

        Functions:
        DC constant current TIG, DC pulse TIG, manual metal-arc welding

        Application industry:
        Petrochemical industry, pressure vessel, electric power construction, vessel, bicycle, nuclear power and pipe laying

        Features:
        The operation panel with reasonable layout, rich functions and convenient operation;

        Parameters such as the slow rise and slow descent of electric current, impulse frequency, duty ratio, the time of advanced gas supply and lagged gas supply can be preset precisely;

        The manual metal-arc welding can adjust the electric current of the arc striking and thrust, with an easier striking of arc and preventing the adhesion of welding rod;

        The argon arc welding can protect the welding gun from water depletion;

        It has two-step and four-step welding control modes;

        It is smaller and lighter and convenient for movement;

        The current and the voltage can be displayed simultaneously. The welding current can be preset precisely;

        TIG can choose the way of the high frequency lifting of arc striking;
