I'll be doing mostly mild steel first then some SS and aluminum every now and then. No odd alloys. Max thickness 1/4 or less.
All scrap metal to start as it's practice practice practice to begin with. I'm not a shop.
So if you were in my shoes what would tungstens and filler wires you take home with a new rig? It comes with 2% Cerium tungsten-1/16, 3/32, 1/8.
