Cebora PROF162 Manual De Instrucciones página 11

Always make sure that the arc fully penetrates the work-
piece, and is never angled forward by more than 10° -
15°. This will avoid incorrect consumption of the nozzle
and burns on the gas nozzle holder.
• Workpiece too thick (see cutting speed/thickness dia-
gram).
• Mass clip not in good electrical contact with the work-
piece.
• Worn nozzle and electrode.
• Nozzle hole too large for the current value set on the
knob F.
• Cutting current too low.
NOTE: When the arc does not penetrate, scraps of
molten metal may damage the nozzle hole.
5.2 THE CUTTING ARC GOES OUT
This problem may be caused by:
• worn nozzle, electrode or diffuser
• air pressure too high
• supply voltage too low
• advancement speed too low.
• cutting current too high for the thickness of the workpiece.
5.3 SLANTED CUT
If the cut is slanted, shut off the machine and replace the
nozzle.
Prevent the nozzle from coming into electrical contact
with the workpiece (including via scraps of molten
metal).
This will cause rapid at times instantaneous destruction
of the nozzle hole, leading to very poor quality cutting.
5.4 EXCESSIVE WEAR ON CONSUMER PARTS
This problem may be caused by:
- gas pressure too low compared to the recommended
value.
- gas supply circuit damaged.
6 HELPFUL HINTS
• If the system air contains a considerable amount of
moisture and oil, it is best to use a drying filter to avoid
excessive oxidation and wear of the consumer parts,
damaging the torch and reducing the cutting speed and
quality.
• The impurities in the air may make it difficult to light the
pilot arc. If this occurs, clean the end portion of the elec-
trode and the interior of the nozzle using very fine-grained
sandpaper.
7 ERROR CODES
In the event of a malfunction, the letter E may appear on
the display X, followed by a number with the following
meaning:
code ERROR
1 Hardware lockup.
2 Hardware lockup.
12 Transfer reed sensor
closed during start-up.
13 Hazardous voltage on Shut the machine off
the torch.
51 Torch not recognized.
52 Start button pressed
during start-up.
53 Start button pressed
while resetting the
pressure switch, which machine off and turn
shows insufficient
pressure, or thermal
reset.
54 Short-circuit between
electrode and nozzle.
55 Electrode finished.
8 ACCESSORIES
8.1 COOLING UNIT
When using the torch CP200, which requires water cool-
ing, you must apply the cooling unit art. 1339 together
with the kit art. 138.
8.2 INTERFACE ART. 197
This circuit allows the following functions on the 14-pin
connector L:
A - Start.
B - Arc transferred signal.
C - Signal in proportion to the cutting voltage.
D - Cutting current adjustment.
8.3 UNIT HV - 16 ART. 482
When you need to cut at distances of more than 9 m from
the power source, use the unit HV-16 with connection Art.
1194 (12 m) or Art. 1194.10 (18 m), plus the torch Art.
1235 (4 m).
SOLUTION
Contact the technical
service department.
Contact the technical
service department.
Replace the reed.
and turn it back on. If
the error recurs, contact
the technical service
department.
Check the type of torch.
Use only original torches.
Open the start com-
mand,shut the machine
off and turn it back on.
Open the start
command, shut the
it back on.
Shut off the machine,
check the electrode and
the nozzle.
Shut off the machine,
replace the electrode
and the nozzle.
