Gases for plasma welding
Normally, the same gas is used for both the plasma and the shielding gas. This avoids
variations in the plasma jet, which would otherwise be the case if two different gases or
gas mixtures were being used.
An argonhydrogen mixture is generally used as the plasma and shielding gas.
However, hydrogen cannot be used as a constituent when welding mild steel or reactive
metals such as zirconium or titanium.
