Functional characteristics

5.1 Shielding gas supply (shielding gas cylinder for welding machine)

5.1.1 Shielding gas volume settings

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!
•  Slowly open the gas cylinder valve.
•  Open the pressure regulator.
•  Switch on the power source at the main switch.
•  Trigger gas test

> see 5.1.2 chapter

function (welding voltage and wire feed motor remain switched off

– no accidental arc ignition).

• Set the relevant gas quantity for the application on the pressure regulator.

Setting instructions

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:
