Gas test

•
Slowly open the gas cylinder valve.
•
Open the pressure regulator.
•
Switch on the power source at the main switch.
•
Initiate gas test function on the machine control.
•
Set the relevant gas quantity for the application on the pressure regulator.
•
The gas test is triggered on the machine control by pressing the

Setting the shielding gas quantity

Welding process
MAG welding
MIG brazing
MIG welding (aluminium)
TIG
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!
