Welder for body metal

I bought a Lincoln 110 volt waaay bcak about 11 years ago. It uses flux core wire or solid wirth gas. I have the adaptors and regulator etc but never got as far as a tank. It's O.K though as the welder does pretty good on sheet metal.

It's partly tecnique as well as machine.I have gotten my best results with a wet rag and stitch welding as the flux core builds up more heat than the mig.

I have not noticed a difference from one brand to another.
