Alright, I'm pretty happy with the stainless steel results I've had for my first try I still need to work on ending the weld w/o burning through the steel...

.040 Tungsten, 13CFH. Scrap 20GA mirror finish stainless. Don't need to use any filler if the joint is tight. Anyone know where I can get some stainless filler rod smaller than 1/16"?

Is there any tricks to minimizing the heat marks on the stainless other than less amperage?
