The electric welding machine no load electricity saver circuit is composed of knife switch Q, fuse FU, capacitor C, resistors R1, R2, thyristor VT, electric welding machine transformer T and trigger switch S, it is shown in the figure 8-10. When knife switch Q is turned on, 380V AC voltage is added to T's circuit by Q(the circuit is made of FU, VT, C, R2 and winding W1). When trigger switch S is not turned on, VT is in off state, C, R2 are connected into the circuit, then the electric welding machine is in electricity saving state, the current which flows T's loop is smaller.
