7 DESCRIPTION OF PROTECTIVE DEVICES
The equipment comes with different protective devices
highlighted by “Err” on the displays
N (see table below
ERROR 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 162C and CP 70C
only.
ERROR DESCRIPTION DISPLAY POSSIBLE SOLUTION
Dangerous voltage Err 40 Call CEBORA Service Department
Torch protection device disengaged Err 50 Mount the protection device
No torch recognition at start-up or recognition mo-
dified in an invalid state
Err 51
Call CEBORA Service Department
Start command pushed while switching on the
power source Err 53
(TRG)
Shut off the power pource, remove the start com-
mand and restart the power source
Worn out electrode Err 55 Replace the electrode and the nozzle
AC supply voltage out of range Err 67 Check the value of supply voltage
High temperature of output diodes or transformer
Err 73
(TH0)
Don’t switch off the power source, to keep the fan
running and thus allow rapid cooling.
Normal operation is restored automatically as
soon as the temperature returns within the allo-
wed limits. If the problem persists, call CEBORA
Service Department.
High temperature of the IGBT module
Err 74
(TH1)
Don’t switch off the power source, to keep the fan
running and thus allow rapid cooling.
Normal operation is restored automatically as
soon as the temperature returns within the allo-
wed limits. If the problem persists, call CEBORA
Service Department.
Gas inlet pressure low Err 78
(GAS LO)
Increase the gas inlet pressure.
Incorrect assemby of the nozzle holder Err 80
(OPN) Check the proper screwing of the nozzle holder
Emergency stop originating from the CNC. Err 90

8 CUTTING QUALITY
There are several parameters and combinations of them
that affect the quality of the cut: This manual shows the
optimal settings for cutting a particular material. However,
due to the installation differences as well as pantographs
and the variation of the characteristics of the cutting ma-
terials, the optimal parameters may require changes with
respect to those indicated in the present cutting tables.
The following points may help the user to make the chan-
ges necessary to obtain a good cutting quality.
As shown in these cutting tables, for each thickness of a
