I am running a Dynatorch with a Hypertherm 1000 using compressed air. With both a 60A tip in 7ga (100ipm, 146V THC) and a finecut 40A tip in 14 ga (90 - 100ipm, 79V THC) I am getting too much dross! I can knock some off with a chisel, but most of it needs to be ground off - pain in the butt. It takes me longer to fix the dross than it does to cut the parts. What am I doing wrong? I wanted to use air because of cost, but if another shielding gas will make the dross chip off, I might consider it. Or, are my settings screwed up?
