I've had a request for stools I make to be built with stainless steel bar instead of cold rolled steel for use outdoors. I have never welded stainless and have a Millermatic 175. Material will be 1-1/2" x 1/4" stainless bar stock.
I know I need to use 308wire and tri-mix gas. The gas is expensive!
Any changes I would need to make on my welder settings?
Any other tips or suggestions? I'd like to have the option of welding stainless but I'm not in a position to buy and learn how to TIG at the moment.
