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.
ERROR DESCRIPTION
Start command present while resetting the opera-
ting mode.
High temperature of output diode or of the transfor-
mer.
High temperature of the IGBT group on power
board.
Gas inlet pressure low.
Guard on HV14 Unit open.
Emergency stop originating from the CNC.
EEPROM error.
Detected current with no plasma arc.
Current out of scale during cutting.
detected current on pilot arc circuit with no plasma arc.
Hazardous voltage: failure of the power circuit.
Communication serial error between control circuit
and torch circuit.
detected current on pilot arc circuit during cutting.
Electrode fi nished.

6 HINTS
- Should the equipment air contain plenty of moisture
and oil the use of a fi lter 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 diffi cult. 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 "Err" on the displays U and V. (See tab. 1).
To assure effi ciency of these protective devices:
• Do not remove nor by-pass the protective devices.
• Replace them with original Cebora spare parts.
POSSIBLE SOLUTION
Shut off the Power Source, remove the start
TRG
command and restart the Power Sourc.
Don't shutting off the Power Source, to keep the
fan running and thus allow rapid cooling.
Normal operation is restored automatically as
TH0
soon as the temperature returns within the allo-
wed limits. If the problem persists, call CEBORA
Service Department.
Don't shutting off the Power Source, to keep the
fan running and thus allow rapid cooling.
Normal operation is restored automatically as
TH1
soon as the temperature returns within the allo-
wed limits. If the problem persists, call CEBORA
Service Department.
Increase the gas inlet pressure.
OPN Check the proper closing of HV14 unit.
Turn on the CNC, exit from emergency and check
rob
the connection between CNC and Power Source.
