The electric welding machine no load electricity saver circuit is composed of knife switch Q, relays K1, K2, intermediate relay KA, AC contactor KM, time relay KT, reed switch SA, diodes VD1, VD2, indication light HL, resistor R, capacitors C1-C3, potentiometers RP1, RP2 and electric welding machine transformer T, it is shown in the figure 8-12. When KM pulls in, but it is not welded, the induced voltage which produced by the both sides of T's secondary winding is rectified by VD2 and then it is added to K2, K2 is pulled in, K2's normally open contact is turned on, KT pulls in and it starts to timing.
