I can not help you with the cnc info. I have a pp60 and I can say that the duty cycle on it seems to be what is claimed. If you want max tip life make sure you have height control on your new table. With that you should have no more tip concerns than you would with any other brand of plasma. I have looked at several brands of plasmas and I believe Everlast has as good or better duty cycle on their units.
