Welder wire feed, great for smaller jobs. Body metal, mower decks etc. comes with self adjusting welding face mask, extra tips and wire, also welding cart. Does not support gas; just wire. I bought this specifically to do a little patching on my utility trailer and several mower decks. used it 5-6 times. It has been in shed every since. Paid over $500. (I think closer to $6oo. after taxes) Call Jerry 902-887-2910 Freetown pei
