Abstract

The invention discloses a power-saving controller for an electric welding machine. The controller comprises a double coupled 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, wherein during welding, as the secondary level of the electric welding machine is short-circuited, the voltage is reduced to around zero volt, the relay is released due to power loss, and the contactor is pulled in after being charged, the electric welding machine gets into a normal welding state in the next step. According to the invention, the controller is safer, more energy-saving and reliable to operate, adopts few components, is economical, convenient and practical, and can be operated naturally, freely, smoothly and easily; as the welding machine is in off-position during welding, the safety hazard that the electric welding machine is electrified when not used is reduced; as the switch can be turned on without manual operation during welding, the defect that the electric welding machine is high in power consumption is reduced, and the working efficiency of the electric welding machine is improved.

Description

technical field [0001] The invention relates to an attachment device of an electric welding machine, in particular to a power-saving controller for the 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 power-saving controller 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 voltage regulator tube, a first ca...
