I'm no welder or welder tech, but I don't think knowing who manufactured the machine will help you much.

Looks like Eastwood designed their own unique features and the parts for it like the circuit board might be completely unique to them.

That said, it looks like other welders offered under the Real Gear and Northern Tools labels. Its been compared to a similar machine from Century but seems not to be as closely related to it.

But unless the internals are same, which I kinda doubt, even if repair parts are available for these others, might not have the parts to fix yours.

This thread includes some pic of the comparable Real Gear and Century machines along with photos of the internals of the Eastwood 175.

Do you have the Eastwood 135 or 175?

This link is to the Northern Tools 135 machine, thought it might help you since it includes a Parts List and schematics.
