hi i have a clarke 160 en turbo mig which seems to have a fault .if the outer nozzle on the torch touches metal when welding it is live.i have never noticed this before.it is only used for fine work ie 1.2 tube. any help please.dave
Most likely spatter in the nozzle conducting power from the swan neck to the shroud, a clean out usually cures it, but if the insulation has broken down a new shroud is the answer.
