Restoring my old ride and ordered some new floor braces they came without the tabs to spot weld them on. Used the 200DX set at 35 amps on DC w/6 cf gas flow and added the tabs to each floor brace. Photo shows an original that i cut from a donor car and the new ones after the tabs were added.

I could use an MTS 160 with .023 wire to set up in the car when welding patch panels in, My millermatic 200 is a little large for that.
