DC pulse TIG welding machine 315A, welding machine in normal operation, this machine can also be electric arc welding, arc welding, argon arc welding arc tungsten does not press the switch contact welding when the arc, but a contact will be brought to the short circuit, tungsten welding on nabuxialai, I put the machine box. The arc contact distance adjustable to 1mm, press the switch will arc slightly, but the feeling current is very small, not big, do not know what the reason is, the machine internal check in online photos, some say that the high frequency transformer is bad, but I see there is a high voltage transformer don't know what is.
The old machine, are generally high voltage capacitor aging.For 10~20 high voltage ceramic capacitors, and together, for.Get rid of the electric shock.
If it is not out of line transformer are bad phenomenon, usually due to electric shock in the short distance from the picture above transformer, high frequency discharge energy shortage, suggestions will shock large distance try.
The difficulty is not small... You may consider asking our factory
Is it all right to call the manufacturer?!
