Welding Tips and Tricks

Omnicut 375-P by Nu-tecsys.
I just picked up plasma cutter that is not working at this time. It’s a US built machine that is in good shape, clean etc. but is not operational except for the fan and power contactor. Doing research on line I find no info on the unit. Dose any one on this forum have the schematics to the circuit board and or general wiring for this machine? Thanks

You’re in for some effort.... it would appear the unit is rather old, the company out of business, and support issues abound.

Thanks cj737 for the links. It looks like a long shot on getting this unit repaired, but its hard to toss it when it's just one or two lousy components.

You might see if you can reach one of the guys who posted in those threads, despite the time, and capture a wiring schematic from them. Worth a try... Or, you’ll likely have to drop the thin off to a repair house and pay the fees for them to diagnose it for you.

This guy has been used by members here before with good results. Seam to remember he got some schematics for something odd.
