Made these last Friday, #16 cup, 35CFH, 60 amps, 3/32 thoriated tungsten. 1/16 308 stainless plate, 1/16 308l filler. I’ve been tring to control my penetration on thin materials. I know the passes aren’t perfect and I’m welding on plate not a joint so it isn’t best case scenario. The pass on the other side wasn’t made by me, just used scrap steel others used to practice. My favourite is the one in the middle.
