SHIELDING GASES


Shielding gas is directed by the torch to the arc and weld pool to protect the electrode and the molten weld metal from atmospheric contamination. 


Argon and helium or mixtures of the two are the most common types of inert gas used for the shielding. Argon hydrogen mixtures are used for special applications.
