INSTRUCTION MANUAL FOR PLASMA CUTTER
IMPORTANT: BEFORE STARTING THE EQUIPMENT,
READ THE CONTENTS OF THIS MANUAL, WHICH MUST
BE STORED IN A PLACE FAMILIAR TO ALL USERS FOR
THE ENTIRE OPERATIVE LIFE-SPAN OF THE MACHINE.
THIS EQUIPMENT MUST BE USED SOLELY FOR WELD-
ING OPERATIONS.
1 SAFETY PRECAUTIONS
WELDING AND ARC CUTTING CAN BE HARMFUL TO
YOURSELF AND OTHERS. The user must therefore be edu-
cated against the hazards, summarized below, deriving from
welding operations. For more detailed information, order the
manual code 3.300.758
ELECTRIC SHOCK - May be fatal.
· Install and earth the welding machine according to
the applicable regulations.
· Do not touch live electrical parts or electrodes with
bare skin, gloves or wet clothing.
· Isolate yourselves from both the earth and the workpiece.
· Make sure your working position is safe.
FUMES AND GASES - May be hazardous to your health.
· Keep your head away from fumes.
· Work in the presence of adequate ventilation, and
use ventilators around the arc to prevent gases from
forming in the work area.
ARC RAYS - May injure the eyes and burn the skin.
· Protect your eyes with welding masks fitted with fil-
tered lenses, and protect your body with appropriate
safety garments.
· Protect others by installing adequate shields or curtains.
RISK OF FIRE AND BURNS
· Sparks (sprays) may cause fires and burn the skin;
you should therefore make sure there are no flam-
mable materials in the area, and wear appropriate
protective garments.
NOISE
This machine does not directly produce noise
exceeding 80dB. The plasma cutting/welding proce-
dure may produce noise levels beyond said limit;
users must therefore implement all precautions required by
law.
PACEMAKERS
· The magnetic fields created by high currents may affect the
operation of pacemakers. Wearers of vital electronic equip-
ment (pacemakers) should consult their physician before
beginning any arc welding, cutting, gouging or spot welding
operations.
EXPLOSIONS
· Do not weld in the vicinity of containers under pres-
sure, or in the presence of explosive dust, gases or
fumes. · All cylinders and pressure regulators used in
welding operations should be handled with care.
ELECTROMAGNETIC COMPATIBILITY
This machine is manufactured in compliance with the
instructions contained in the harmonized standard EN50199,
and must be used solely for professional purposes in an
industrial environment. There may be potential difficul-
ties in ensuring electromagnetic compatibility in non-
industrial environments.
IN CASE OF MALFUNCTIONS, REQUEST ASSISTANCE
FROM QUALIFIED PERSONNEL.
2 INSTALLATION
2.1 TORCH ASSEMBLY (Fig. 1)
This power source is suitable only for CEBORA torch-
es and is supplied with model CP90 (IT-DE Pat. Pend-
ing).
This torch has been manufactured in full observance
of the safety precautions contained in the standard
EN50192. This standard requires that the live nozzle
placed vertically on a horizontal surface may not be
touched by the conventional test probe, the specifica-
tions for which are set forth by the standard itself. In
observance of this requirement, it is now impossible
to use the parts previously manufactured, since it
would not have been possible to avoid contact with
the test probe when using long electrodes and gas
nozzles. A gas nozzle holder has therefore been
designed with a protective tube that prevents any
accidental contact with live parts, and allows the use
of a new long nozzle that can cut in corners or recess-
es. To avoid the hazards created by using the previous
parts, this nozzle holder has been designed with a
left-hand thread, and must therefore be screwed on
counter-clockwise.
Insert the torch fitting into the guard R, then onto the fit-
ting P, firmly tightening the ring-nut to avoid air leaks that
could damage or interfere with smooth operation of the
torch.
Do not dent the current pin or bend the pegs of
the torch fitting. A dented pin may not disconnect,
while a bent peg does not allow proper insertion
onto the fixed fitting P, thereby preventing the machine
from working.
Use the screws provided to fasten the guard R on to the
panel.
