1, can be directly connected to the argon arc welding torch, of course, have to connect the gas road, the current to the desired position, the line of arc (that is, contact short circuit, arc), direct welding can be2, note: welding torch negative electrode
Add a high frequency arc striking and hand switch circuit and solenoid valve,
