I need help choosing a welder

[Fender1325]

I was in fact able to run continuous beads with the HF on 16 without blow through, but it was also .035 wire. The larger problem was warpage. I warped that practice sheet a fair amount, but then again youre not really supposed to run long continuous beads on sheet metal. The .030 seems to take longer to get a pool going but also more forgiving to work with.
