INSTRUCTION MANUAL FOR CEBORA CP 200 PLASMA TORCH
READ THIS MANUAL CAREFULLY BEFORE USING
THIS TORCH.
This torch has been manufactured in strict observan-
ce of the safety restrictions of the standard EN 50192.
In compliance with the provisions of these standards,
CEBORA SPA declares that this torch must be used
only with CEBORA generators. Spare and consumer
parts are integral parts of the torch, and therefore
CEBORA considers the use of NON-ORIGINAL parts
to be equivalent to tampering. The company thus
declines any responsibility, in compliance with the
spirit of the standard, including those implied or sta-
ted in the warranty agreement.
Any use not described herein is to be considered PROHI-
BITED.
Only qualified personnel should start, use and service the
torch.
Comply with all current safety regulations.
1 FOREWORD
This torch has been designed to cut electrically conduc-
tive materials (metals and alloys) using the plasma arc
procedure, and uses clean, dry air as plasma gas and
distilled water mixed with glycol for cooling. It is available
in two versions: a) MAC model for manual use, and b)
DAC model for use on automatic systems.
"PLASMA ARC" cutting takes place due to the high tem-
perature generated by a concentrated electric arc, and
thus may lead to seriously hazardous situations. It is the-
refore essential to attribute the utmost importance to the
chapter on SAFETY PRECAUTIONS in the manual of the
generator to which the torch is connected.
This manual must be stored carefully in a place known to
the operator. It should be consulted whenever doubts
arise, accompany the machine throughout its operative
life and be used for ordering spare parts.
2 TECHNICAL SPECIFICATIONS
Maximum I2 cutting current = 200 A.D.C.
Duty cycle X = 60% with I2 = 200 A
Duty cycle X = 100% with I2 = 160 A
Running voltage U2 = 140 V (contact tip-work piece
distance 4 mm)
Running voltage U2 = 100 V (contact tip in contact with
the work piece)
Plasma gas pressure with 6-m cable = 3 bar (0.3 Mpa /44
PSI)
Maximum air throughput = 48 liters/minute.
Cooling liquid pressure = 3 bar
Cooling liquid throughput = 1.4 liters/minute.
3 ACCESSORIES AND CONSUMER PARTS
The torch nozzle diameter depends on the cutting current
and (as also shown on the machine front panel) must be
the following:
• ø 1 mm with I2 current up to 45/50 A.
• ø 1.3 mm with I2 current from 45 to 90 A.
• ø 1.6 mm with I2 current from 80 to 130 A.
• ø 1.8 mm with I2 current from 120 to 160 A.
CAUTION! The contact tip must not touch the work piece
at currents above 45/50 A; it is therefore essential to use
the spring or two-point spacer.
4 SAFETY
This torch is fitted with an electrical safety device on the
torch assembly, to prevent hazardous voltages when
replacing the contact tip, electrode or contact tip holder.
5 TORCH MAINTENANCE
Always cut off the power supply to the machine before
any maintenance operations, which must be performed
by qualified personnel.
5.1 - Replacing consumer parts (Fig. 1,2).
Parts subject to wear include the electrode A and the
contact tip C, which can be replaced after unscrewing the
tip holder D.
The electrode A should be replaced when a 1.5 mm deep
crater forms in the center.
Use only the extractor provided to screw and unscrew the
electrode.
The contact tip C should be replaced when the center
hole is worn or widened compared to the new part. Make
sure the tip holder D is firmly tightened after replacement.
CAUTION! The tip holder D should be screwed onto
the torch assembly only with the electrode A and the
contact tip C mounted.
If these parts are missing, the equipment may not
function properly and operator safety is jeopardized.
5.2 - Replacing the torch (Fig. 1).
Machines marked S , designed to work in hazardous
environments, have a guard requiring the use of a tool to
disassemble and assemble the torch.
