Torch Maintenance - Cebora PC 6061/T Betriebsanleitung

6.2 TORCH MAINTENANCE

Making reference to Fig. 5 and Fig 6, parts subject to
wear are electrode A, swirl ring B, nozzle C and nozzle
protection E. These should be replaced after unscrewing
the nozzle holder D.
Electrode A must be replaced when it shows an approx
1.2 mm deep crater at the center.
CAUTION: do not use sudden force to unscrew the elec-
trode; work gradually to release the thread. The new
electrode must be screwed into the seat and fastened in
place without tightening fully.
The nozzle C must be replaced when the central hole
is damaged or wider than that of a new part. Delays in
replacing the electrode or nozzle will cause the parts to
overheat, and jeopardize the life-span of the swirl ring B.
Make sure that the gas nozzle holder D is firmly tightened
after replacement.

WARNING: screw the nozzle holder D onto the welding
torch body only when electrode A, swirl ring B, nozzle C
and nozzle protection E (only for CP 161) are assembled.
If any of these parts are missing, this will interfere
with smooth operation of the machine and, especial-
ly, jeopardize operator safety.
6.3 PRECAUTIONS AFTER REPAIRS.
After making repairs, take care to organize the wiring so
that there is secure insulation between the primary and
secondary sides of the machine. Do not allow the wires
to come into contact with moving parts or those that heat
up during operation. Reassemble all clamps as they were
on the original machine, to prevent a connection from
occurring between the primary and secondary circuits
should a wire accidentally break or be disconnected.
Also mount the screws with geared washers as on the
original machine.
