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