Here is a pic of the way I welded the rear floor to the 2x2 square

You can see the series of spot welds vs. one long weld - done this way to reduce warping.

This type of weld is not idea for roll cages, motor mounts, etc but is a great way to control heat for sheet metal welds. The newer Miller 252 and FJ40 Charles favorite, the MM200 both have a feature to do this for you automatically by setting up a spot - stich times.

Lincoln offers a welder in the medium price range that has an optional add on module to do this. It's called a power mig 180 and it also the infinite adjustment on the heat that the lower end Miller and Hobart machines don't offer. Both of these features are cool, but I wish Hobart and Miller offered them as I prefer those brands. None the less, with some rust restoration to do, this might be a machine to consider. If you have a really good sense of timing and rhythm you might not need these features. I really like the stitch feature and I am considering buying one just to do rust-o-ration with.

Have fun with it.
