Throttle switch of sub-arc welding machine
There is only one microswitch on the welding gun to control the main circuit of argon arc welding machine. First, open the solenoid valve to introduce argon, and then output high-frequency arc. At the same time, the main circuit of welding machine is connected, and no-load voltage and welding arc are generated by high frequency. When two wires are short-circuited, they will catch fire, and the air outlet control is generally on the welding machine power supply.
