Hmm, to save time and money I thought I'd ring R-Tech as they have been very helpful in the past. It seems my torch would not be good for CNC as it is a contact-start head and CNC really needs an HF Pilot arc. He said it "might" work but the arc may not always strike when told and that would waste the work-piece. Sounds like my project is not going far unless i sell my plasma and upgrade the unit which would blow most of my budget.
