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!
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.
• Always re-fit the yellow protective cap when not using the shielding gas connection.
• All shielding gas connections must be gas tight.
