[sudo-discuss] helium regulator needed

does anyone have a spare regulator for a high-pressure helium tank? Argon or other noble gases (also Nitrogen) would work fine. I need this because I got a TIG welder recently from harbor freight tools. It's the cheapest TIG welder i've ever seen, lacks all the most basic features. But it still needs inert gas, and so i need a regulator (i have a tank) so if you have one, please let me know. thank you -jake
