I have a Lincoln Precision TIG 185.

I made some welds in 2008 and it worked fine.

It will pop the circuit breaker for the shop, so I have to hot wire it from more than one breaker.
The wife is also an electrical engineer, and she busts me for fire hazard.

My brother has the same thing and makes beautiful welds on old Mauser bolt handles.
