In the ready-to-use state, the welding torch MIG / MAG consists of:
1. Cable assembly with equipment
2. Handle / Handle tube for AUT Version
3. Torch neck e. g. MB 240 D with equipment and consumables
These elements combine together to form a functional unit which produces an
electric welding arc when supplied with the appropriate resources.
For the welding process, a wire electrode is transported through the welding
torch, whereby the arc and the weld-pool are protected by inert gas (MIG) or
active gas (MAG).
The wire electrode or filler wire is fed through the contact tip. The contact tip
transfers the welding current to the wire electrode. The arc is formed between
the wire electrode and the workpiece. The torch neck is liquid-cooled in all ver-
sions, the cable assembly has been designed accordingly.
Fitting the cable assembly
Select the type of wire and the suitable wire guide liner for your application.
– Push the pre-fitted wire guide liner – guide spiral liner or plastic core liner –
from the central plug through to the torch neck with the cable assembly laid
out straight.
– Screw the union nut tight using the multiple spanner.
– Cut the guide spiral liner off flush to the torch neck, with 401 D and 501 D
on the contact tip holder.
– Make sure there is no burr on the cutting edge.
For information on how to install new wire guide liners and
about correct procedure for assembly, consult chapter 11
entitled "Servicing".
