•
Place the shielding gas cylinder in the cylinder holder and secure it from tipping over using the
securing chain!
•
Before connecting the pressure regulator to the gas cylinder, open the cylinder valve briefly to blow out
any dirt.
•
Mount the pressure regulator on the gas cylinder valve.
•
Screw gas hose connection crown nut onto the output side of the pressure regulator.
•
Screw the gas hose connection nipple onto the G¼" connection nipple.
•
Tighten gas hose on pressure regulator to be gas tight.
•
Fit the gas hose and G1/4" crown nut onto the relevant connection on the welding machine, and fit the
wire feed unit (if present on this version).

5.13.2 Setting instructions

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!
