Electronic Schematic Diagrams

Can anybody help me find an Schematic Diagram for this electronic device?

HMC-410 welder controler (can be HOBART or ARC MASTER brand).
Hello Atrocious,
The PDF file you linked me to is the Wiring diagram for the HMC-410 controller, not actually the Electronics Schematic that I need. I appreciate your help anyway. Thank you.

I hope I have the correct device. If not, let me know. This is for a Thermal Arc HMC-410:
