[Tom '74 911]

I have a Miller EconoTIG that a friend gave me and Jim2 is correct, the bottom end is still pretty hot to be useful on really thin stuff; at least with my limited skills. I bought a another Miller machine, a Dynasty 200DX I think, and its low end is great... but it was not cheap!

I'm not familiar with Lincolns, but if sheetmetal and car stuff is on your to do list, I'd definitely look into the specs for the low end on the machine.
