Abstract
The invention discloses a safe energy-saving control circuit of an electric welding machine. The safe energy-saving control circuit comprises an alternating-current power supply, a linkage switch, a first fuse, a second fuse, a first transformer, a second transformer, a first resistor, a second resistor, a diode, a capacitor, a relay, an alternating-current contactor and a microswitch. When the electric welding machine is used, the linkage switch is turned on and is immediately pressed when a pair of electric tongs of the electric welding machine is held with hand, the relay is electrified to be turned on, the alternating-current contactor is also electrified to be turned on, a normally-opened contact switch of the relay is turned on, a contact switch of the alternating-current contactor is also turned on, and the electric welding machine begins to work. When welding is stopped, the microswitch is released, the relay is powered off and disconnected, the alternating-current contactor is released, the power supply of the electric welding machine is disconnected, and the electric welding machine stops working. When the electric welding machine is in use or completes work, the microswitch can automatically reset as long as the pair of electric tongs is put down, the power supply is immediately disconnected, an electric shock accident is avoided, and meanwhile electric energy is greatly saved.
