HOBART DCC-353-P welder contorl box

Does anyone have any experience rewiring a Hobart DCC-353-P welder to work without the control module box? To make it work more like the civilian version? On the Military Spec version they added a vane type on board air compressor a Hydrovane 25 and made a few other changes. The Welder I have no longer has the air compressor, the welder still works great, but it need the control module box that houses everything to excite the genset and regulate the voltage plus control the air compressor. It's a rather nice 350 amp welder with independent 3kw genset, powered by an ultra reliable perkins diesel and would really like to get it up and running again.

I have the welder too. Don't have remote box, have not used it as a welder, but the 30kw generator was appreciated during an extended power outage during Christmas a few years ago. I checked to see if it could be retapped for 240vac but it couldn't. Mine has a toggle to switch between local and remote control. It still has the compressor. Actually what lead me to this thread. Anybody have a manual for the hydrovane?

By chance do either of you have a parts machine? I'm in need of the ignition switch!

Can these be mounted on those surplus generator trailers?
