How to make gold/purple welds

[Rambozo]

what size of cup would you have used if you was welding this rambozo?

Since I would only do short welds on stainless exhaust tubing, and move around to help control the heat put into the part, and warping, I would probably use a 1/16" tungsten and a #7 or #8 as long as I could get access with it.

Your filler is regular steel, from what I can see of the copper color filler in the pic and I suppose your metal is as well? It won't give the heat lines like Stainless.. Also for a shinier weld, adjust your argon flow up or use a gas lens or a smaller one.
