  • GR -303 wiring schematics

    I bought a Hobart GR-303 and a lot of the wires are off behind the front panel. I am looking for a schematic of the wiring for this welder if anybody would share it.

            Hello, i just bought a GR-303 as well, and have no output. I need schematics or any other information on the GR-303. I have to figure out the rats nest of wires. It seems to be a later one, Ford 200cu. Spec 5404B. Can you help?

            Thanks
