4.3 GOUGING ("GOUGE" OPERATING MODE)
To run gouging operations, which is only available for the
hand torch, use the dedicated consumables.
This operation makes it possible to remove defective
welds, separate welded pieces, prepare edges, etc.
The value of the current to be used depends on the thick-
ness and quantity of material to be removed. It may help
to set the supply pressure to 4.5 - 5.0 bar.
With the welding torch in slanted position (fig. 6) proceed
towards the melted metal so that the gas coming out of
the welding torch keeps it away.
Vary the slant of the torch with respect to the workpiece
and/or the advance speed to obtain different levels of
penetration. As melted dross tends to stick to the nozzle
holder and nozzle guard during this procedure, it is best
to frequently clean them so as to avoid double arc events
which may destroy the nozzle in a matter of seconds.
Given the strong (infra-red and ultraviolet) radiation emis-
sion during this operation, it is recommended that the op-
erator and people in the vicinity wear adequate PPE.

5 REPLACING CONSUMABLES
IMPORTANT: Switch the power source off before re-
placing any consumables Making reference to Fig. 7 for
CP70C torch, parts subject to wear are electrode A, diffus-
er 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.

parts are missing, this will interfere with smooth op-
eration of the machine and, especially, jeopardize
operator safety.
6 HELPFUL HINTS
- Should the equipment air contain plenty of moisture
and oil the use of a filter dryer is recommended. This will
prevent excessive oxidation and wearing of consuma-
bles, welding torch damage and reduction in cutting ra-
pidity and quality.
- Air impurities cause oxidation of the electrode and noz-
zle and may make pilot arc start-up more difficult. If this
condition is present, clean the electrode terminal end
and the nozzle interior with thin abrasive paper.
- Make sure that the new electrode and nozzle that are
going to be assembled are perfectly clean and oil-free.
- To avoid welding torch damage always use Cebora
original parts.
7 DESCRIPTION OF PROTECTIVE DEVICES
The equipment comes with different protective devices
highlighted by O, P AND Q LEDS (see table below ER-
ROR CODES).
To assure efficiency of these protective devices:
• Do not remove nor by-pass the protective devices.
• Replace them with original Cebora spare parts.
• Always replace any damaged parts of the machine
or the welding torch with original parts.
• Use torches CEBORA Type CP 70C only.
The nozzle C must be re-
placed 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 noz-
zle holder D is firmly tight-
ened after replacement.
WARNING: screw the noz-
zle holder D onto the welding
torch body only when elec-
trode A, swirl ring B, nozzle
C and nozzle protection E are
assembled. If any of these
