Fellow has a Miller Engine powered unit, trying to ID it.
Looks like a Wildcat Teccumseh OHV engine DC output S/N jb516058 Looks like about 200 amp Owner claims it is a "2E"
Pretty beat up, someone messed with the wiring. I really don't want to start in on it without some documentation
Comments?
You gotta have some pictures.
Roughneck 2E
Sounds like someone converted it to DC. Welding machines designed for DC, especially DC produced from single phase (as produced by the Roughneck 2E), will have an output inductor (AKA smoothing inductor) to keep the arc going reasonably steady while the AC input to the rectifier goes through the zero crossing. A good AC to DC conversion will also install this inductor; if your machine does not have it, then it is not a very good conversion and you will probably not like welding with it. If it does have an inductor it might be a decent conversion worth trying as is.
It should be easy to convert back to AC - remove the diodes and return the wiring to that shown in the manual.
Appears to have factory stock inductor and diodes. Front panel does not quite match the manuals.
The DC version of this machine was the 2F:
I would be inclined to sketch up the actual wiring diagram by marking up either the 2E or 2F wiring diagrams, and try and fix it.
