The normal function of argon arc welding welding, arc not normal, press the switch can hear the fire place in the machine (what is I do not know the name, like the discharge gap? Is the two small pieces of metal plate - like contact not contact place) with loud no problem before, there are sparks. Some people say that the problem is the high frequency don't ask the master, the arc, which is the problem, can repair? Is worth repairing? Can not repair welding repair in our county those people say. Thank god!
The problem is one of several 12V relays on the circuit board. After the power is switched on, the switch of the gun is pressed, and it is known by the multimeter.
Put the appliance (that is, the 2 small metal plate) the gap is great, and then not to high voltage ceramic capacitor discharger beside the blue change.
Ignition can indicate that the welder is good. Replace the torch with the ground wire. It's ok.
