Just bought this Miller econotig today. Bought from original owner's son. Owner ran a home shop autobody and bought it new 10 years ago. His dad passed 7 years ago. Hasn't been touched since. Son says his dad didn't know how to use it but had a friend come over to do any TIG work. Said it was barely used and it looks like he's telling the truth.
I think I got a good deal. Found it on CL.
