Hi there,was doing some welding today when the arc wouldn't strike anymore,just wire coming out so seems like there isn't an earth anymore bewteen the clamp and torch,I've checked the earth clamp and cable,liner and took the torch cover off to have a look inside and can't see any damage at all,so I suspect the problem might be inside the machine somewhere,I wouldn't know where to start looking so any help is much appreciated,though I didn't check how the wires are inside the torch liner as I had a quick look but didn't see a way to remove the liner,thank you for the help.
