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.
(Please refer to the applicable standard "EN 60974-9: Arc
welding equipment. Part 9: Installation and Use).
- 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 your eyes with the relative filters, which must
comply with UNI EN 169 or UNI EN 379, mounted on masks or
use helmets that comply with UNI EN 175.
Use the relative fire-resistant clothing (compliant with UNI
EN 11611) and welding gloves (compliant with UNI EN 12477)
without exposing the skin to the ultraviolet and infrared
rays produced by the arc; the protection must extend to
other people who are near the arc by way of screens or non-
reflective sheets.
- 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 (Tab.
1).

(EN)

- The flowing of cutting currents generates electromagnetic
fields (EMF) around the cutting circuit.
Electromagnetic fields can interfere with certain medical
equipment (e.g. Pace-makers, respiratory equipment, metallic
prostheses etc.).
Adequate protective measures must be adopted for persons
with these types of medical apparatus. For example, they
must be forbidden access to the area in which plasma cutting
systems are in operation.
This plasma cutting system conforms to technical product
standards for exclusive use in an industrial environment for
professional purposes. It does not assure compliance with
the basic limits relative to human exposure to electromagnetic
fields in the domestic environment.
The operator must adopt the following procedures in order to
reduce exposure to electromagnetic fields:
- Fasten the two cables as close together as possible.
- Keep head and trunk as far away as possible from the cutting
circuit.
- Never wind cables around the body.
- Do not cut with the body within the cutting circuit. Keep both
cables on the same side of the body.
- Connect the cutting current return cable to the piece being
cut, as close as possible to the position of the cut itself.
- Do not cut while close to, sitting on or leaning against the
plasma cutting system (keep at least 50 cm away from it).
- Do not leave objects in ferromagnetic material in proximity of
the cutting circuit.
- Minimum distance d= 20 cm (Fig. P).
- Class A equipment:
This plasma cutting system conforms to the technical product
standards for exclusive use in an industrial environment and
for professional purposes. It does not assure compliance with
electromagnetic compatibility in domestic dwellings and in
premises directly connected to a low-voltage power supply
system feeding buildings for domestic use.
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.
All protective technical measures MUST be taken as
provided in 7.10; A.8; A.10 of the applicable standard EN
60974-9: Arc welding equipment. Part 9: Installation and
Use".
- 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.
