Setting the shielding gas quantity

Welding process

Recommended shielding gas quantity

MAG welding

Wire diameter x 11.5 = l/min

MIG brazing

Wire diameter x 11.5 = l/min

MIG welding (aluminium)

Wire diameter x 13.5 = l/min (100 % argon)

TIG

Gas nozzle diameter in mm corresponds to l/min gas throughput

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

Factor

75% Ar/25% He

1.14

50% Ar/50% He

1.35

25% Ar/75% He

1.75

100% He

3.16

NOTE

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!
