This may sound silly but in my workshop i have a tig welder which is all ready set to go, have got all the gas, tungstens, absolutely everything but the only thing stopping me now is the earth lead to earth the work. Whats the best thing to do? i have got the clamps for either end, its just the wire, is it best to go to a welding supplier or do a DIY job of one, like get a mains wire and split the earth from it?? hummmmm
