5.2.1.1 Control lead connection
TIG welding machines are equipped ex works with a dedicated connection socket for the welding torch
control cable (5- or 8-pole). As mobile machines offer more free space, they may even feature two control
cable connection sockets. The functionality increases with the number of poles. One of these connection
sockets may be converted or retrofitted

5.2.2 Shielding gas supply (shielding gas cylinder for welding machine)
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
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.
5.2.2.1 Connecting the shielding gas supply
• Place the shielding gas cylinder into the relevant cylinder bracket.
• Secure the shielding gas cylinder using a securing chain.
