My dad had one of those years ago. I think it had a continental engine in it (?)
As I remember it only has one 15 amp outlet on it, they usually were just intended for tools with universal motors , I wouldn't plug a fridge or such into it. Worked fine for welding tho, lots of iron, nice stable arc.
Things weigh a TON tho, just barely qualify as 'portable'....
(He sold it when he bought the Miller)
The ones in the pic don't look all that well cared for, You could probably find one in a lot better shape...
