Cebora Torch CP162C MAR:
Press the torch trigger to strike the pilot arc. If you do not
start cutting, after 2 seconds, the pilot arc goes out and
then to turn it back on, press the trigger again.
Do not keep the pilot arc lit unnecessarily in the air: this
will increase consumption of the electrode, diffuser and
nozzle.
Connect the clamp of the ground cable to the workpiece
sure that the clamp and the workpiece are in good elec-
trical contact, especially with painted sheet metals, ox-
idized, or insulated metal. Do not connect the clamp to
the piece of material to be removed.
Hold the torch upright while cutting.
At fi nished cutting and after having released the trigger,
air will continue to leave the torch to allow it to cool.
Do not turn off the unit before the end of this time.
With cutting current from 20 to 40 A and a 0.9 mm diam-
eter nozzle it is possible to make a cut directly supporting
the nozzle to the workpiece (drag cut).
For currents higher than 40 A it is essential to use the
spring-loaded spacer or two tips to avoid putting in di-
rect contact the nozzle cap with the piece to be cut (cut
standoff).
In case you need to make holes or should start the cut
from the center of the workpiece (see fi g. 4), you must
hold the torch at an angle and slowly straighten it so that
the molten metal is not sprayed onto the nozzle protec-
tion. This must be done when making holes in pieces
more than 3 mm.
If making circular cuts, we recommend using the special
caliper supplied upon request. It's important to remind
that the caliper may make it necessary to employ the
above-mentioned starting technique.
Cebora Torch CP162C DAR:
Follow the instructions contained in the cutting chart
regarding the pierce height, the working height and the
maximum cutting thickness in function of the current (see
fi g. 5). Moreover, refer to the instruction manual of the
optional kit for art.433 pantograph spacer

4.2 GRID CUTTING (SELF-RESTART OPERATING
MODE)
SELF
RESTART
MILD STEEL
Air 5.5 bar
To cut drilled plates or grids, select this operating mode.
For the material settings, gas and cutting current, refer to
paragraph 4.1, as well as for the adjustment of the work-
ing pressure. When cutting is completed, keep the knob
pressed and the pilot arc will restart automatically.
Use this function only if required, to avoid excessive
wearing of the electrode and of the nozzle.
4.3 GOUGING ("GOUGE" OPERATING MODE)
GOUGE
MILD STEEL
Air 5.5 bar
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
