95% Ar - 5% Hydrogen vs 100 Argon cleaner??
95% Ar - 5% Hydrogen vs 100 Argon cleaner??
(OP)
Is the 95-5 a cleaner shielding gas as well as an aid to penetration?? I am welding 300 series SS to each other. GTAW, .060 wall. Where can I find onfo that educates me on these variables??

We use 95/5 in plasma torches. It is hard to use as a shield gas becuase is has better thermal conductivity and my reduce penetration, but yes, it is cleaner.
5% H2 is not a saftey issue. You are below the flamability limits, and by the time you add enough air to have some O2 you are even lower.
