Showstopper Plasma Cutter retrofit

If you have an HF start plasma, the HF is created between tip and electrode, you might still not believe me but anyways.
There could be some HF in the tip so keep that in mind.

Yes, that is the reason i never advise using such torches with ohmic.
And all the plasma sources i have are HF/HV start ones.
I am sure i can cobble something together to avoid the high voltage but not worth it, i like my THCAD's not crispy
Oh, i do have a Hypertherm MAX 43 that has blow back start but i have no consumables for it, despite ordering them several times.

I do not have any torch with shield, so i can not test although i do have 2 of THCAD for now.

 
I assume you mean that the tip ”sticks out” from the torch? You could always wire the sensing between the tip and work.

I have my 30XP setup like that but I use a cheap solid state relay rather than a THCAD.
