5.1.7 Shielding and plasma gas supply
WARNING
Risk of injury due to improper handling of shielding gas cylinders!
Improper handling and insufficient securing of shielding gas cylinders can cause seri-
ous injuries!
• Observe the instructions from the gas manufacturer and any relevant regulations concern-
ing the use of compressed air!
• Do not attach any element to the shielding gas cylinder valve!
• Prevent the shielding gas cylinder from heating up.
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 sup-
ply 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.
