Hi, I have inherited a Snap On Mig 130 Turbo and I want to practice laying on some welds at various power settings and wire speeds. I am just going to use a piece of scrap 3/16 steel and flux core wire. As a starting point what power settings should I use and what wire speed. There are 2 switches one either 2 or 1 and the other either max or min. The wire speed doesn't have numbers but has 10 segments marked on the dial from small segment rising to large. Sorry if this sounds too simplistic but we all have to start somewhere. Thanks, Barry
