I need a small 110 welder for sheetmetal work. The local pawn shop has a used Lincoln 3200HD that I can have for $150 out the door. The only catch is that it is missing the regulator, The ground clamp is wasted and the gun is kind of beat up. Plus it has a few minor scratches on the casing. Is it worth it? I don't really have any experience in pricing the smaller welders.
