Abstract

The invention discloses an electric welding machine safe electricity-saving starting device which comprises a double-linkage switch, a relay, a contactor, a fuse protector, an electric welding machine transformer, a welding gun, a unijunction transistor, a first voltage-regulator tube, a second voltage-regulator tube, a first capacitor, a second capacitor, a third capacitor, a first resistor, a second resistor and a third resistor. During welding, an electric welding machine secondary pole is subjected to short circuiting, voltages are lowered to about 0V, the relay loses power and is released, the contactor obtains power and is closed in an attracting mode, and an electric welding machine is in a next-step normal welding state. During operation, safety, energy saving and reliability are achieved, the number of used elements is low, economy, convenience and practicability are achieved, operation is natural, working is free, and operation is smooth and comfortable. When welding is not carried out, the electric welding machine is in a power-off state, the potential safety hazards that the electric welding machine is not used and has electricity are lowered, during welding, the switch does not need to be turned on manually, accordingly, high power consumption of the electric welding machine is lowered, and the working efficiency of the electric welding machine is improved.

Description

technical field [0001] The invention relates to an accessory device of an electric welding machine, in particular to a safe and energy-saving starting device for an electric welding machine. Background technique [0002] The AC welding machines currently in use mostly use manual power switches. When welding, the power is manually turned on, and the power is kept on when there is no welding for a short time, causing many safety hazards and unnecessary power consumption. Contents of the invention [0003] The object of the present invention is to provide a safe and energy-saving starting device for an electric welding machine in order to solve the above problems. [0004] The present invention achieves the above object through the following technical solutions: [0005] The present invention includes a double linkage switch, a relay, a contactor, a fuse, a welding machine transformer, a welding torch, a unijunction transistor, a first voltage regulator tube, a second voltag...
