Welding torch connection
We can only guarantee correct functioning of our machines when used with our range of welding
torches.
The correct spirals or cores must be used for the relevant wire diameter and wire type.
Welding torch with insulatated liner:
A capillary tube must be installed in the central connection.
Welding torch with Teflon or plastic core:
The capillary tube must be removed from the central connection.
Preparing the welding torch for the welding task:
• Shorten the Teflon core and surrounding guide pipe so that the distance to the drive roller is as short
as possible.
• The Teflon core and the guide pipe must not be deformed.
• Deburr the Teflon core and the guide pipe.

2
Rapid-action closure coupling, red (coolant return)
3
Rapid-action closure coupling, blue (coolant supply)
4
19-pole connection socket (analogue)
For connecting analogue accessory components (remote control, welding torch control
lead, intermediate drive, etc.)
5
7-pole connection socket (digital)
For connecting digital accessory components (remote control, welding torch control
lead, etc.)
• Insert the central plug for the welding torch into the central connector and screw together with crown
nut.
• Lock the connecting nipples on the cooling water tubes into place in the appropriate rapid-action
closure couplings:
connect the red return line to red rapid-action closure coupling (coolant return) and
the blue supply line to the blue rapid-action closure coupling (coolant supply).
• Depending on the type of torch used, insert the torch control lead plug into either the 7-pole
connection socket (digital) or the 19-pole connection socket and lock.
Only MIG/MAG torches with special functions (additional control lead):
• Insert the torch control lead plug into either the 7-pole connection socket (digital) or the 19-pole
connection socket (depending on the version) and lock.
