I am TIG welding stainless and am using 100% Argon. I will run out of my argon over the weekend.

I have two cylinders of an argon + helium blend that I use on stainless using MIG.
Will this blended gas work with TIG welding stainless? The term "heli-arc" is synonymous with TIG welding but I am un-sure if this will work.

Thanks guys!
