Inserting the wire electrode

6.10 Inserting the wire electrode
The removal of the welding power source cover is only done with compact machines; with
decompact machines, the wire spool is inserted into the wire feed unit.
With decompact machines, open the casing of the wire feed by unlocking and opening the cover to an
upwards position.

6.10.1 Removing the wire feed unit cover

For the following processes the cover must be removed; to protect the machine it is essential
that the cover is fitted back into position afterwards.
• Unlock the right-hand cover on the machine.
• Tilt the cover forwards, then remove upwards.

6.10.2 Fixing of the pin reel (adjustment of the pre-tensioning)

As the spool brake at the same time also secures the wire spool retainer, the following working
steps are to be carried out for every spool change and before every adjustment of the spool
brake.
