5.1.5 Shielding gas supply (shielding gas cylinder for welding machine)
WARNING
Risk of injury due to improper handling of shielding gas cylinders!
Improper handling and insufficient securing of shielding gas cylinders
can cause serious injuries!
• Place shielding gas cylinder into the designated holder and secure with
fastening elements (chain/belt)!
• Attach the fastening elements within the upper half of the shielding gas
cylinder!
• The fastening elements must tightly enclose the shielding gas cylinder!
Risk of accidents when exceeding the maximum size of the shielding gas cylinder!
The maximum size for shielding gas cylinders and the filling pressure are specified for
the machine. When exceeding the limits, the cylinders may tip at an angle of up to 10 °
(according to IEC 60974-2) and people may be injured as a result.
• Use shielding gas cylinders with a maximum geometric volume of 33 l at a filling pressure
of 300 bar.
An unhindered shielding gas supply from the shielding gas cylinder to the welding torch is a
fundamental requirement for optimum welding results. In addition, a blocked shielding gas
supply may result in the welding torch being destroyed.
• All shielding gas connections must be gas tight.

• Before connecting the pressure regulator to the gas cylinder, open the cylinder valve briefly to blow
out any dirt.
• Tighten the pressure regulator screw connection on the gas bottle valve to be gas-tight.
• Screw the gas hose connection to the outlet side of the pressure regulator gas-tight.
