Shielding gas supply (shielding gas cylinder for welding machine)
WARNING
Incorrect handling of shielding gas cylinders!
Incorrect handling of shielding gas cylinders can result in serious and even fatal injury.
• Observe the instructions from the gas manufacturer and in any relevant regulations
concerning the use of compressed air!
• Place shielding gas cylinders in the holders provided for them and secure with fixing
devices.
• 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.
