hi guys,
i want to use handle torch with a new cnc machine
and i read somewhere that there's a problem with high frequency starting arc .

and what's the available types ?

HF is not a problem with the right kind of controls and THC. It's all about grounding and designing for noise suppression. If you don't want to deal with an HF start machine a lot of the modern plasma units of less than 100A (Hypertherm 1000 thru 1650 series, Hypertherm 45, 65 & 85, Thermal Dynamics 52, 82 and 102 series) use "contact blowback" arc start (no high frequency).
