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!
• Secure shielding gas cylinders using the standard fastening elements on
the unit (chain/belt)!
• The fastening elements must tightly enclose the shielding gas cylinder!
• Attach the fastening elements within the upper half of the shielding gas
cylinder!
• Do not attach any element to the shielding gas cylinder valve!
• Observe the instructions from the gas manufacturer and any relevant
regulations concerning the use of compressed air!
• Avoid heating the shielding gas cylinder!
CAUTION
Faults in the shielding gas supply.
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.
Before connecting the pressure regulator to the gas cylinder, open the cylinder valve briefly to
expel any dirt.
• Place the shielding gas cylinder into the relevant cylinder bracket.
• Secure the shielding gas cylinder using a securing chain.
