Curtis,
I have one that is fairly similar to yours. At least, based on your description, it is fairly similar. Mine is powered by an old Chrysler engine and is rated at 300A. I think it is a GP300. MIne was built in 1945 for the US Navy. It is definitely a monster. Mine hasn't been fired up since I acquired it and it probably didn't run for a long time before that. I scored it for free and have been trying to find the time to get it running ever since. Good luck with your project and let me know if you need any help. I have managed to get a copy of the schematic for my welder; it probably isn't drastically different from yours.

Daniel

thanks daniel for the reply. i was able to get additional info from literature@millerwelds.com (1800-332-9448). they didn't have an operator's manual for my model (GP258) but had one for model GP259, Spec #1819. very helpful, 47 pages. they will email it to you for free. would appreciate a copy of your schematic. will try to awaken the beast as soon as i can. the more info the better.

Hi there this is Fred Thompson at Port Alberni B.C. Canada, Is there any chance that you would please email the imformation you have on your 300 amp Hobart welder I have one up and running it was made in 07/06/1945 with Chrysler T118-502 power unit and a Cw1282 radiator made for tropical use. From what Horbart could tell me the unit and 11 more were shipped to Montreal Canada on July 09 1945 to Rudel Machine but Horbart couldn't ship me any wiring diagrams or anything else on it so I would very much like to be able to get this imformation from you. Thank You very much Fred Thompson .....theoldbear@shaw.ca Ph. 1-250-723-3653.

Curtis -
I do not remember model # BUT
I had a welder that fit your disc. 250 amp - 110 dc power supply and was powered by 4 cyl. flathead jeep motor - Very good welding unit- not bad on gas & it had a huge gas tank!-
Welders gone but I think I still have manual - if you do not get info you need let me know and i will look for it.
