hi been working on my car today and when welding the wire sparks inside the swan neck, i cant understand why this is happening, i think i need a new part but unsure which one i need, the set im using is a clarke 100e mk1 i think
it happens inside the swan neck and the end of the swan neck that attaches to torch is all burnt, still dont know what part i need, the wire feeder coil that goes inside the swan neck is very small could this be doing it?
