PLASMA CUTTING SYSTEMS DESIGNED FOR PROFESSIONAL
AND INDUSTRIAL USE
1. GENERAL SAFETY INSTRUCTIONS FOR PLASMA ARC CUTTING
The operator should be properly trained to use plasma cutting
systems safely and should be informed about the risks related to
arc welding procedures and associated techniques, about relevant
safety measures and emergency procedures.
(See also the "IEC TECHNICAL SPECIFICATION or CLC/TS 62081":
INSTALLATION AND USE OF ARC WELDING APPARATUS AND
RELATED TECHNIQUES).
- Prevent direct contact with the cutting circuit; the no-load
voltage supplied by the plasma cutting system may be
dangerous under certain circumstances.
- When the cutting circuit cables are being connected or checks
and repairs are carried, out the cutting system should be
switched off and disconnected from the power supply.
- Switch off the plasma cutting system and disconnect it from the
power supply before replacing worn torch parts.
- Make the electrical connections and installation according to the
health and safety standards and legislation in force.
- The plasma cutting system should be connected only and
exclusively to a power supply network with the neutral lead
connected to earth.
- Make sure that the power supply plug is correctly connected to
the earth protection outlet.
- Do not use the plasma cutting system in damp or wet places or in
the rain.
- Do not use cables with worn insulation or loosened connections.
- Do not cut on containers, receptacles or piping that contains or
has contained inflammable liquids or gases.
- Do not work on materials cleaned with chlorinated solvents or in
the vicinity of such substances.
- Do not cut on containers under pressure.
- Remove all flammable materials (e.g. wood, paper, cloth etc.)
from the working area.
- Provide adequate ventilation or facilities for the removal of fumes
produced by plasma cutting work; a systematic approach is
needed in evaluating the exposure limits for fumes produced by
cutting work, which will depend on their composition,
concentration and the length of exposure itself.
, *
- Ensure there is adequate electrical insulation with regard to the
plasma cutting torch nozzle, the workpiece and any (accessible)
earthed metal parts in the vicinity.
This is normally achieved by wearing gloves, shoes, head
coverings and clothing designed for this purpose and by using
insulating platforms or mats.
- Always protect the eyes using masks or helmets with special
actinic glass.
Use special fire-resistant protective clothing and do not allow the
skin to be exposed to UV and IR rays produced by the arc; other
people in the vicinity of the arc should also be protected, by
shields or non-reflecting curtains.
- Noise levels: if particularly intensive cutting operations cause
daily personal noise exposure (LEPd) of 85 dBA or more, suitable
personal protection equipment must be worn.
- The electromagnetic fields generated by the plasma cutting
process may interfere with the operation of electrical and
electronic equipment.
People using vital electrical or electronic apparatus (e.g. pace-
makers, respirators etc.) should consult a doctor before
stopping in the vicinity of areas where this plasma cutting
system is used.
We strongly advise users of vital electrical or electronic
apparatus against using this plasma cutting system.
)
- This plasma cutting system complies with the requirements of
the technical standard for the product for use only and
exclusively in industrial environments and for professional
purposes.
It is not guaranteed to meet electromagnetic compatibility
requirements in the home.
EXTRA PRECAUTIONS
PLASMA CUTTING OPERATIONS
- In environments with heightened risk of electric shock;
- In confined spaces;
- In the presence of inflammable or explosive materials;
MUST be evaluated in advance by an "Expert supervisor" and
must always be carried out in the presence of others who have
been taught how to intervene in emergencies.
Technical protection measures MUST BE adopted as
described in 5.10; A.7; A.9. of the "IEC TECHNICAL
SPECIFICATION or CLC/TS 62081".
- Cutting operations MUST BE PROHIBITED if the operator is
supporting the weight of the power source (using slings for
example).
- The operator MUST NEVER BE ALLOWED to carry out cutting
operations if above ground level, unless safety platforms are
used.
- WARNING! USING THE PLASMA CUTTING SYSTEM SAFELY.
The safeguards provided by the manufacturer (interlocking
system) can only be guaranteed to work properly if the torch
model and corresponding power source as indicated in the
"TECHNICAL DATA" are used.
- DO NOT USE non-original torches or consumable parts.
- DO NOT ATTEMPT TO USE THE POWER SOURCE with torches
that are made for cutting or WELDING procedures but are not
contemplated in this instruction manual.
- FAILURE TO COMPLY WITH THESE RULES may give rise to a
SERIOUS safety hazard for the user and may also damage the
apparatus.
RESIDUAL RISKS
- TIPPING: place the plasma cutting power source on a horizontal
surface with adequate load-bearing capacity; otherwise (e.g.
sloping or uneven floor etc.) the apparatus is in danger of tipping
over.
- IMPROPER USE: it is dangerous to use the plasma cutting
system for any work other than that for which has been designed.
- Never lift the machine without first disconnecting and removing
all interconnection and power supply cables and piping.
The only permitted way to lift the machine is that described in the
"INSTALLATION" section of this handbook.
2. INTRODUCTION AND GENERAL DESCRIPTION
Plasma cutting system with compressed air – 3-phase, with fan, on
wheels. Used for fast cutting without deformation on steel, stainless steel,
galvanised steel, aluminium, copper, brass etc. The cutting cycle is
started by a pilot arc, which can be struck by a short circuit between
electrode and nozzle (versions with I max £
(HF) discharge (versions with I max ³
Possibility of using extension nozzles.
MAIN FEATURES
- Cutting current adjustment.
- Torch voltage control device.
- Control devices for air pressure, shorting in torch (only for versions
with I max ³ 70A).
2
- Thermostat safeguard.
- Air pressure display.
- Torch cooling control (only for chopper version):
- Storage on internal E PROM of 10 latest alarm events (only for
chopper version).
- Overvoltage, undervoltage, phase failure (only for chopper version).
STANDARD ACCESSORIES
- Plasma cutting torch.
- Connector kit for compressed air hookup.

OPTIONAL ACCESSORIES

- Spare electrode-nozzle kit.
- Electrode-nozzle extension kit (where provided for).
