• Insert the cable plug on the work piece lead into the "+" welding current connection socket and lock by
turning to the right.
• Insert the welding current plug on the welding torch into the welding current connection socket and
lock by turning to the right.
• Remove yellow protective cap on G¼ connecting nipple.
• Screw welding torch shielding gas connection tightly onto the G¼" connection nipple.
• Plug the welding torch control cable plug into the welding torch control cable connection socket and
secure.
• With water cooled welding torches, the coolant lines are connected on the cooling module or reverse
cooling unit.
5.2.1.1 Control lead connection
All standard 5- and 8-pin TIG welding torches can be connected to this machine and operated (except for
8-pin potentiometer torches). 5-pin EWM function torches with X-TECHNOLOGIE are also supposed.

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.
