how to makeTHCAD10 work with pilot arc plasma

yeah i know it's weird, but i only need a way to have the ARC OK bit activating an output to open a relay so it can be disconnected from ground.
As in your video you can see the plasma working even though the ground is connected on the nozzle to make it a pilot arc.

Or i can add a relay activated by the TORCH ON signal with a delay of 1 second.

Setting that in hal is easy, it should be something like this:
net arc-ok-in mesa-7i76-output-02
That is just as an example, you can use the "show hal configuration" from the machine menu in axis to look for pins and find their exact names.
The issue i have is using a relay to disconnect that while it may have over 100V at over 30A going through it, it might get interesting.

LOL yes, i did think about it, the wire they use for the pilot arc ground is 1.5mm² i guess it does not have that much amps going through, and with this solution i might be able to keep the nozzle longer as the arc will be on the plate and not on the nozzle.

I'll give it a try today and report back

Quite the opposite, it will be on the nozzle.
Shielded torch, notice the power and pilot arc connections:

Un shielded torch, again notice the connections:

mine is like the 1st picture, less the pilot arc switch, on this machine it's always connected
that is why the thcad does not work, always getting the same value what ever the distance.

i'm not saying this is the solution but it might be part of it

Not really, yours does not have a separate shield.
Picture 2 is like yours.
