SHIELDING GAS CONSIDERATIONS
GTAW (TIG) - Manual AC welding. Argon gas gives good stability.
For heavier sections add helium for increased arc penetration.
Helium requires higher gas flow rates.
GMAW (MIG) - Spray Transfer. Argon gas gives excellent cleaning
action. Add helium may to aid filler metal flow and for
deeper arc penetration. Don't use pure helium.
NOTE: If oxyacetylene is used, employ a neutral or slightly
reducing flame and Aufhauser 900 FLUX. Remove flux residue
with hot water.
