Electric shock prevention and energy saving electric welder control circuit

摘要

It is an object of the present invention to solve the problems of the prior art as described above, and to provide a control circuit of an electric shock prevention and energy-saving electric welder that can eliminate the possibility of an electric shock accident at no load and minimize standby power loss.;The present invention to achieve this purpose is to cut off the AC voltage supply to the secondary side line by the operation of the low-voltage electronic circuit operation, and to prevent the electric shock under no load by operating the micro voltage near zero, When the electrode holder is in contact with the welding base material, the electronic monitoring circuit detects this and performs primary welding through the auxiliary conducting part. The load current generated at this time is sensed by the current detecting part, and the secondary power source is finally connected between the welding machine and the base material. Configure to be supplied.
