Stainless Steel - 100 Amps - Copper Electrode
H17 Plasma / Nitrogen Shield / Nitrogen Preflow & Postflow
(H17 = 17.5% Hydrogen / 32.5% Argon / 50% Nitrogen)
This gas combination gives the best cut quality and minimum dross levels

WARNING
Do not connect H17 (combustible gas) to the gas inputs (Pre/Postflow, Plasma, or Shield) at the same time as
Oxygen or Air.
* Use an arc transfer height (ignition height) of .200” (5.1 mm) for cutting and .100” (2.5 mm) for marking.
