Just a quick question while you are on here Andy, I am having trouble with my Tig welder is this gas ok for mild steel with a tig set, it works ok with the mig and I was wondering if the problem was with the gas through the set because my the earth, etc all seem to be ok, even checked the collet is the right one for the tungsten etc.
