Helpful Hints - Cebora PLASMA SOUND PC 110/T Betriebsanleitung

To run gouging operations, select this mode, which is
only available for the hand torch.
For the material settings, gas and cutting current, refer to
paragraph 4.1 as well as for the adjustment of the work-
ing pressure.
This operation makes it possible to remove defective
welds, to separate welded pieces, to prepare edges, etc.
For this operation use a 3,1 mm ø nozzle. The value of
the current to be used varies from 60 to 130 A depending
on the thickness and quantity of material to be removed.
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. The welding torch
slanted position versus the workpiece depends on the
penetration you want to obtain.
As melted dross tends to stick to the nozzle holder and
nozzle protection during this procedure, it is recom-
mended to frequently clean them so as to avoid prob-
lems (double arc) which may destroy the nozzle in few
seconds. Given the strong (infrared and ultraviolet) radi-
ation emission during this operation, it is recommended
that the operator and people nearby wear an adequate
protection.

5. REPLACING THE CONSUMABLES
IMPORTANT: Switch the power source off before re-
placing any consumables.
Making reference to Fig. 8 and 8/A for CP162C torch and
Fig.9 for CP70C torch, parts subject to wear are electrode
A, diffuser B, nozzle C and nozzle protection E. These
should be replaced after unscrewing the nozzle holder D.
Sometimes for for CP162C torch it may be necessary to
clean the inner part of the swirl ring B. In that event, use
the special tool as shown in Figure 8/A.
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.

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.
Fig.8/A
WARNING: screw the nozzle
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 parts are
missing, this will interfere
with smooth operation of
the machine and, espe-
cially, jeopardize operator
safety.
