5.2.1

Shielding gas supply (shielding gas cylinder for welding machine)

Risk of injury due to improper handling of shielding gas cylinders!
Improper handling and insufficient securing of shielding gas cylinders can cause
serious injuries!
•
Observe the instructions from the gas manufacturer and any relevant regulations
concerning 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
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.
