On the 65 and 85 there is also a built in voltage divider (for THC use) with 5 different divider ratios....this way you do not have to bring raw arc voltage (just uner 300 vdc open circuit) out with your wiring...rather you can use a divided voltage between 20 and 50:1 ratio.
Hypertherms industrial plasma systems have far more complex interface capability....
