Helium-rich gas mixtures require a higher gas volume!
The table below can be used to correct the gas volume calculated where necessary:
Shielding gas
75% Ar/25% He
50% Ar/50% He
25% Ar/75% He
100% He
Incorrect shielding gas setting!
If the shielding gas setting is too low or too high, this can introduce air to the weld pool
and may cause pores to form.
•
Adjust the shielding gas quantity to suit the welding task!
