I have questions about the fine cut consumables for the PM 45 machine torch. I see that they seem to be rated for 30 amps as they were originally designed for the PM 30. I want to try these out when cutting thinner metals. BTW I'm new to all this CNC plasma cutting. So please go easy on me here.

1. So what I am wondering is can I use the fine cut consumables (t30V) on the machine torch p/N: t45m but still use the p/n:220719 retaining cap so I have the ability to utilize the ohmic sensing feature with the feather touch device I bought form CandCNC (that I am still planning on hooking up soon)?
2. If I were to run these at 45 amps will I burn up the nozzle and electrode prematurely?
3. Can I use the deflectors that I purchased for the t45m and the swirl ring for the t45m and simply swap out the nozzle and the electrode to the fine cut p/n's?
I now this all sounds kind of dumb but it appears that many of the part numbers mentioned in the hypertherm literature appear to be compatible as near as I can figure. My goal here is to try to use my feather touch and the fine cut consumables at the same time if that is possible and if so I simply need help clearly understanding which part numbers too select to get the correct configuration. The DTHC IV manual from CandCNC trys to explain this on page 124 but it confuses me too. It seems to show that you can use mostly all T45M parts and simply change only the nozzle and the shield.
I currently have the p/n: 220673 shield (and a spare). I have a 220713 retaining cap (stock with the machine torch), and a p/N: 220719 Ohmic retaining cap that I bought thinking this is what I need for the ohmic sensor from CandCNC. And I have the stock part number nozzles 220671 and swirl ring 220670 and several 220669 electrodes for spares. I am hoping all I still need to buy here are the smaller nozzles p/N: 220480 and the smaller amperage electrodes p/N: 220478 if need be and maybe some of the smaller swirl rings p/N: 220479 if required. Please advise. Thanks, Ed
