5.1.10.2 Gas test
– setting the shielding gas volume
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.
• Set the relevant gas quantity for the application on the pressure regulator.
• The gas test can be triggered by briefly pressing the Gas test/Rinse hose package push-button
either at the control or underneath the protective cap next to wire feeder (welding voltage and wire
feed motor remain switched off, no unintentional arc ignition).
Shielding gas flows for around 25 seconds or until the button is pressed again.
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:
