• Lay out the torch tube package in an extended position.

• Loosen the knurled nuts A2 on the wire feed and swivel them outwards at the sides.

The clamping elements B2 with the counter-rollers swivel upwards automatically.

• Unwind the wire electrode in a clockwise direction from the wire spool D2 and insert it through

the wire inlet nipple E2, the grooves in the drive rollers and the guide tube into the capillary tube

and Teflon core with the guide tube C2.

• Press the clamping elements B2 with the counter-rollers back downwards

(wire electrode must lie in the groove of the drive roller).

• Swivel the knurled nuts A2 which set the counter-pressure back upwards.

The pressing force must be adjusted with the knurled nuts such that the wire electrode is

conveyed but slips when the wire spool jams.

• Press the wire inching button until the wire electrode projects from the welding torch.

Danger of injury!

When inching the wire, never point the torch at persons or animals.

6.8.3 Setting the spool brake

Tighten spool brake only to the point where the wire spool no longer runs on when the torch

trigger is released!

• Tighten the hex. C1 in the spool holder, simultaneously countering with the hexagonal nut B1 to

tighten.
