Does anyone have any ideas about how to weld a piece of 24 gauge SS? This is a long piece of trim from a classic car. It needs about a 1/4 inch weld.

I tried using a Dynasty 350 on 5 amps. Too hot when the arc starts and not hot enough once it stabilizes. Tried using heat sinks to keep the heat away from the trim. Tried pulse. No luck.

Any suggestions?
