Equipment damage and impurities of the welding result due to worn O-rings.
Worn O-rings have a negative impact on the torch cooling. Insufficient cooling causes damage
to the welding torch. Gas losses and the penetration of atmospheric oxygen can also occur and
can adversely affect the welding result.
• Check the O-rings every time the welding torch is converted and grease or replace if neces-
sary.
5.2.1 Turning the torch neck
This function is only available with the "CG" and "CW" version!
• Unfasten the crown nut by several turns from the handle until the torch neck can move freely.
• Rotate the torch neck into the required position.
• Tighten the crown nut hand-tight until the torch neck can no longer be moved.
5.2.2 Changing the torch neck
