We have a HPR130XD and recently ordered a bottle of H35 to try on some stainless stuff, but they messed up and sent a mix of 35% Hydrogen 65% Nitrogen. Not sure if I want to even bother trying to cut with it, I know I found a article online quoting the H35 as this mix but I'm sure it was a typo as it should be 65% Argon. Has anyone tried to cut with this mix?
