I use the Plasma version of Mach, I think the only difference is the screen and the way buttons are displayed, functionally I believe they are the same. Using Mach3 Plasma there is a button on the main screen to turn THC on/off. I haven't used Mach mill or turn.
I'm not the right guy to ask about plasma cutters, hopefully someone else can answer your question. I think I will avoid the high frequency start for my next one, I don't have any problems with it interfering with the CNC, but it doesn't start a pilot arc reliably. I get a lot of condensed moisture in the air supply which may be part of the problem.
