Who makes Marquette welders?

Im going to pick up a Marquette 12150 plasma cutter (3015 Plasma Cutting System..) Its a big old 35A model but I know jack about the brand. Seems like its an OEM for names like Snap-on, Miller, Century...? Its non-functional but has a new torch, dirt cheap! I hope its something with the controller board that I can repair. It may be made in Italy from other models (12151) in the line which I think is worth about $2 more than Chinese....but $$$ more in consumables.
