7.6 Setting up the welding gas supply
WARNING Risk of injury from incorrect handling of shielding gas bottles
Incorrect handling and inadequate fastening of shielding gas bottles can
lead to serious injuries.
► Follow the instructions of the gas manufacturer and those for the
pressurized gas supply!
► There must be nothing attached to the valve on the shielding gas
bottle!
► Avoid heating the shielding gas bottle!
• The flow of welding gas to the torch must be adjusted at the pressure reducer of the welding gas
supply.
• The desired volume flow of welding gas at the torch is set in the power supply software.
NOTICE In order to use the complete range of functions of the digital
gas control, we recommend setting the incoming volume flow from
the pressure reducer higher than the welding gas volume actually
required at the torch.
Recommended incoming volume flows:
Welding gas 8 – 18 l/min, 30 l/min
• The welding gas displaces oxygen in the welding area outside the pipe to prevent oxidation of the
material and is introduced via the welding torch.
Forming gas 3-5 l/min
• The forming gas displaces oxygen inside the pipe and is usually introduced into the pipe interior via
forming gas plugs.
NOTICE Do not exceed max. 10 bar inlet pressure at the gas inlet connec-
tion of the power supply, otherwise damage may occur.
NOTICE Use hoses from the hose connection set included in the scope of
delivery for the welding gas supply.
