That's a darn good welder. Made in the 40's to 60's as far as I could find. I found some old ads for them on the net. I looked because I used to have one. The fine adjustment comes out and can be used with an extension cord for a remote. The one I had had a Chrylser IND 251 engine out of a combine or something. A little much for 200 amps but it sure welded smooth. If you had 3 phase power you could run it off that too if you uncoupled the engine. The welding generator was on one end and the electric motor on the other. I saw a factory built Hobart with a Jeep engine and it also still had the electric motor to run the generator.
