I have a chance to pick up a miller roughneck 2e from a family member who inherited it and doesn't do much welding. Anyone have experience with these. It's ac only which is fine because I learned to weld on a Lincoln 225 buzzbox anyway it'll be real nice having a portable welder for side work and theres no way I can afford a new ranger or bobcat. Seems like a good machine just a thunderbolt run off a tecumseh engine it seems. Thinking I'm gonna grab it. Anyone have experience with these?
