There is a local guy selling a Used (says lightly used) Lincoln Precision Tig 185. I would be using it for projects like gas tanks, welding bungs on a radiator and intake tubing so nothing really heavy. I know lincoln is a good brand but what do you guys thing. He is asking for $1,100 including the tank. Things I should ask him or look at when inspecting the machine? From what I have read it should be a good machine for my intended purposes.
