I found mine to be reasonably sensitive. Was having real trouble in the winter and just got a cheap in line moisture filter thingy (R Tech plasma and from them, was about £50 I think) that cured the issue.Not that sensitive are they?
Here is a picture of the torch.At this point it might be easier to take the top cover off, the left side pix shows the screw looking like it's partially removed already.
look for a set of spark points or not.
Did you check if the electrode moves up and down in the torch?
Sadly no it doesn't so I assume it's HF.Did you check if the electrode moves up and down in the torch?
It's so easy,if it's not HF it will move and it should be spring loaded

Fizzy needs a non HF one for his CNC build."Sadly" ????

...and where you pick off the torch voltage for the THC sensing....Blowback style is preferable but not a necessity, depending on electronics used on CNC control HF may cause interference unless proper care is taken with shielding signal wires.
You pull the torch voltage (for height sensing) off the power supply after the diodes (rectifier stack) and before the blocking inductor.Just tried it. Working perfectly. Cut 10mm easy enough but got nothing thicker I can afford to waste.
I think it is HF start. Just have to be careful when building the cnc bed. Shielded wires etc.
All I have to go on is my Oerlikon, and that needs 4 Bar or it won't start.I wonder what the best psi is to run it?
