I have a Hypertherm Max20 plasma cutter that has fried 2 resistors on it's circut board and I need to know what their value is to replace them. The resistors are R25 and R26 on the main PCB marked Chopper, It's always been a great home machine and any help would be greatly appreciated. I'm hopping that someone has the same machine and could open it up and tell me what these 2 resistors values or color codes are. Thank You Very Much

I don't know much about electronics but I'd say that the fried resistors are a symptom of your problem, not the cause. IOW, some other failure has caused excessive current through the resistors & fried them. Something like a shorted diode, SCR, ... (?). Just replacing the resistors is likely to result in 2 more fried resistors. As far as finding the real problem, I can't help, sorry.
