MIG/MAG welding
Warning – Risk from electrical current!
If welding is carried out alternately using different methods and if a welding torch and an
electrode holder remain connected to the machine, the open-circuit/welding voltage is applied
simultaneously on all cables. The torch and the electrode holder should therefore always be
placed on an insulated surface before starting work and during breaks.
Connection and welding leads (e.g. electrode holder, welding torch, workpiece lead, interfaces)
may only be connected when the machine is switched off.
Follow the safety instructions on the opening pages entitled “For Your Safety”!
We can only guarantee the perfect functioning of our machines when used with our range of
accessory components.
6.7.1
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.
