The electric welding machine no load electricity saver circuit is composed of relay drive circuit, low voltage detection control circuit, high voltage timing control circuit or voltage self-adaptive tracking regulation circuit, it is shown in the figure 8-5. The low voltage detection control circuit is made of relay K's normally closed contact K2, steady voltage diode VS1, resistor R1 or transistor V6. The high voltage timing control circuit consists of steady voltage diode VS2, resistors R2, R6, capacitor C2 or transistor V5. The relay drive circuit is composed of relay K, transistors V1, V2 and diode VD3.
