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.

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
