ELECTROMAGNETIC COMPATIBILITY (EMC) AND CE SAFETY
EMC INTRODUCTION
Hypertherm's CE-marked equipment is built
in compliance with standard EN50199. The
equipment should be installed and used in
accordance with the information below to
achieve electromagnetic compatibility.
The limits required by EN50199 may not be
adequate to completely eliminate interference when the affected equipment is in
close proximity or has a high degree of
sensitivity. In such cases it may be necessary to use other measures to further reduce interference.
This plasma equipment is designed for use
only in an industrial environment.
INSTALLATION AND USE
The user is responsible for installing and
using the plasma equipment according to
the manufacturer's instructions. If electromagnetic disturbances are detected then it
shall be the responsibility of the user to
resolve the situation with the technical
assistance of the manufacturer. In some
cases this remedial action may be as simple
as earthing the cutting circuit, see Earthing
of Workpiece. In other cases it could involve
constructing an electromagnetic screen
enclosing the power source and the work
complete with associated input filters. In all
cases electromagnetic disturbances must
be reduced to the point where they are no
longer troublesome.
ASSESSMENT OF AREA
Before installing the equipment the user
shall make an assessment of potential
electromagnetic problems in the surrounding area. The following shall be taken into
account:
a. Other supply cables, control cables,
signalling and telephone cables; above,
below and adjacent to the cutting
equipment.
b. Radio and television transmitters and
receivers.
c. Computer and other control equipment.
d. Safety critical equipment, for example
guarding of industrial equipment.
e. Health of the people around, for
example the use of pacemakers and
hearing aids.
f. Equipment used for calibration or
measurement.
g. Immunity of other equipment in the
environment. User shall ensure that other
equipment being used in the environment is
compatible. This may require additional
protection measures.
h. Time of day that cutting or other activities
are to be carried out.
Earthing of Workpiece
Where the workpiece is not bonded to earth
for electrical safety, nor connected to earth
because of its size and position, for
example, ship's hull or building steelwork, a
connection bonding the workpiece to earth
may reduce emissions in some, but not all
instances. Care should be taken to prevent
the earthing of the workpiece increasing the
risk of injury to users, or damage to other
electrical equipment. Where necessary, the
connection of the workpiece to earth should
be made by a direct connection to the
workpiece, but in some countries where
direct connection is not permitted, the
bonding should be achieved by suitable
capacitances selected according to national
regulations.
Note. The cutting circuit may or may not be
earthed for safety reasons. Changing the
earthing arrangements should only be
authorized by a person who is competent to
assess whether the changes will increase
the risk of injury, for example, by allowing
parallel cutting current return paths which
may damage the earth circuits of other
equipment. Further guidance is given in IEC
TC26 (sec)94 and IEC TC26/108A/CD Arc
Welding Equipment Installation and Use.
Screening and Shielding
Selective screening and shielding of other
cables and equipment in the surrounding
area may alleviate problems of interference.
Screening of the entire plasma cutting
installation may be considered for special
applications.
CE Safety
Power supplies are intended for an over
voltage category III power source. See
Section 6.1 of IEC 60974-1.
Power suplies are intended for environmental conditions of pollution degree 3
minimum. See Section 6.1 of IEC 60974-1.
Power supplies must not be used for a
pipe-thawing application. See Section
17N of IEC 60974-1.
The size of the surrounding area to be
considered will depend on the structure of
the building and other activities that are
taking place. The surrounding area may
extend beyond the boundaries of the
premises.
METHODS OF REDUCING EMISSIONS
Mains Supply
Cutting equipment must be connected to the
mains supply according to the manufacturer's recommendations. If interference
occurs, it may be necessary to take
additional precautions such as filtering of
the mains supply. Consideration should be
given to shielding the supply cable of
permanently installed cutting equipment, in
metallic conduit or equivalent. Shielding
should be electrically continuous throughout
its length. The shielding should be connected to the cutting mains supply so that
good electrical contact is maintained between the conduit and the cutting power
source enclosure
Maintenance of Cutting Equipment
The cutting equipment must be routinely
maintained according to the manufacturer's
recommendations. All access and service
doors and covers should be closed and
properly fastened when the cutting equipment is in operation. The cutting equipment
should not be modified in any way except for
those changes and adjustments covered in
the manufacturer's instructions. In particular, the spark gaps of arc striking and
stabilizing devices should be adjusted and
maintained according to the manufacturer's
recommendations.
Cutting Cables
The cutting cables should be kept as short
as possible and should be positioned close
together, running at or close to the floor
level.
Equipotential Bonding
Bonding of all metallic components in the
cutting installation and adjacent to it should
be considered. However, metallic components bonded to the workpiece will increase
the risk that the operator could receive a
shock by touching these metallic components and the electrode at the same time.
The operator should be insulated from all
such bonded metallic components.

on your machine near specific hazards.
• WARNING safety messages precede related
instructions in this manual that may result in injury
or death if not followed correctly.
• CAUTION safety messages precede related
instructions in this manual that may result in
damage to equipment if not followed correctly.
Fire Prevention
• Be sure the area is safe before doing any cutting.
Keep a fire extinguisher nearby.
• Remove all flammables within 35 feet (10 m) of the
cutting area.
• Quench hot metal or allow it to cool before handling
or before letting it touch combustible materials.
• Never cut containers with potentially flammable
materials inside – they must be emptied and
properly cleaned first.
• Ventilate potentially flammable atmospheres before
cutting.
• When cutting with oxygen as the plasma gas, an
exhaust ventilation system is required.
Explosion Prevention
• Do not use the plasma system if explosive dust or
vapors may be present.
• Do not cut pressurized cylinders, pipes, or any
closed container.
• Do not cut containers that have held combustible
materials.
CUTTING CAN CAUSE FIRE OR EXPLOSION
WARNING
Explosion Hazard
Argon-Hydrogen and Methane
Hydrogen and methane are flammable gases that
present an explosion hazard. Keep flames away from
cylinders and hoses that contain methane or hydrogen
mixtures. Keep flames and sparks away from the torch
when using methane or argon-hydrogen plasma.
WARNING
Hydrogen Detonation with Aluminum Cutting
• When cutting aluminum underwater, or with the
water touching the underside of the aluminum, free
hydrogen gas may collect under the workpiece and
detonate during plasma cutting operations.
• Install an aeration manifold on the floor of the water
table to eliminate the possibility of hydrogen
detonation. Refer to the Appendix section of this
manual for aeration manifold details.
Touching live electrical parts can cause a fatal shock
or severe burn.
• Operating the plasma system completes an
electrical circuit between the torch and the
workpiece. The workpiece and anything touching
the workpiece are part of the electrical circuit.
• Never touch the torch body, workpiece or the water
in a water table when the plasma system is
operating.
Electric Shock Prevention
All Hypertherm plasma systems use high voltage
in the cutting process (200 to 400 VDC are
common). Take the following precautions when
operating this system:
• Wear insulated gloves and boots, and keep your
body and clothing dry.
• Do not stand, sit or lie on – or touch – any wet
surface when using the plasma system.
• Insulate yourself from work and ground using dry
insulating mats or covers big enough to prevent any
physical contact with the work or ground. If you must
work in or near a damp area, use extreme caution.
• Provide a disconnect switch close to the power
supply with properly sized fuses. This switch allows
the operator to turn off the power supply quickly in
an emergency situation.
• When using a water table, be sure that it is correctly
connected to earth ground.
ELECTRIC SHOCK CAN KILL
• Install and ground this equipment according to the
instruction manual and in accordance with national
and local codes.
• Inspect the input power cord frequently for damage
or cracking of the cover. Replace a damaged power
cord immediately. Bare wiring can kill.
• Inspect and replace any worn or damaged torch
leads.
• Do not pick up the workpiece, including the waste
cutoff, while you cut. Leave the workpiece in place
or on the workbench with the work cable attached
during the cutting process.
• Before checking, cleaning or changing torch parts,
disconnect the main power or unplug the power
supply.
• Never bypass or shortcut the safety interlocks.
• Before removing any power supply or system
enclosure cover, disconnect electrical input power.
Wait 5 minutes after disconnecting the main power
to allow capacitors to discharge.
• Never operate the plasma system unless the power
supply covers are in place. Exposed power supply
connections present a severe electrical hazard.
• When making input connections, attach proper
grounding conductor first.
• Each Hypertherm plasma system is designed to be
used only with specific Hypertherm torches. Do not
substitute other torches which could overheat and
present a safety hazard.
Cutting can produce toxic fumes and gases that
deplete oxygen and cause injury or death.
• Keep the cutting area well ventilated or use an
approved air-supplied respirator.
• Do not cut in locations near degreasing, cleaning or
spraying operations. The vapors from certain
chlorinated solvents decompose to form phosgene
gas when exposed to ultraviolet radiation.
• Do not cut metal coated or containing toxic materials, such as zinc (galvanized), lead, cadmium or
CUTTING CAN PRODUCE TOXIC FUMES
beryllium, unless the area is well ventilated and the
operator wears an air-supplied respirator. The
coatings and any metals containing these elements
can produce toxic fumes when cut.
• Never cut containers with potentially toxic materials
inside – they must be emptied and properly cleaned
first.
• This product, when used for welding or cutting,
produces fumes or gases which contain chemicals
known to the State of California to cause birth
defects and, in some cases, cancer.

combustibles.
LE COUPAGE PEUT PROVOQUER UN INCENDIE
OU UNE EXPLOSION
AVERTISSEMENT
Risque d’explosion
argon-hydrogène et méthane
L’hydrogène et le méthane sont des gaz inflammables et
potentiellement explosifs. Conserver à l’écart de toute
flamme les bouteilles et tuyaux contenant des mélanges à
base d’hydrogène ou de méthane. Maintenir toute flamme
et étincelle à l’écart de la torche lors de l’utilisation d’un
plasma d’argon-hydrogène ou de méthane.
AVERTISSEMENT
Détonation de l’hydrogène lors du
coupage de l’aluminium
• Lors du coupage de l’aluminium sous l’eau, ou si l’eau
touche la partie inférieure de la pièce d’aluminium, de
l’hydrogène libre peut s’accumuler sous la pièce à couper
et détonner lors du coupage plasma.
• Installer un collecteur d’aération au fond de la table à eau
afin d’éliminer les risques de détonation de l’hydrogène.
Se référer à l’annexe du manuel pour plus de
renseignements sur les collecteurs d’aération.
SÉCURITÉ
Hypertherm Systèmes plasma 1a-3
2/12/01
Toucher une pièce électrique sous tension peut provoquer
un choc électrique fatal ou des brûlures graves.
• La mise en fonctionnement du système plasma ferme un
circuit électrique entre la torche et la pièce à couper. La
pièce à couper et tout autre élément en contact avec cette
pièce font partie du circuit électrique.
• Ne jamais toucher le corps de la torche, la pièce à couper
ou l’eau de la table à eau pendant le fonctionnement du
système plasma.
Prévention des chocs électriques
Tous les systèmes plasma Hypertherm utilisent des hautes
tensions pour le coupage (souvent de 200 à 400 V). On
doit prendre les précautions suivantes quand on utilise le
système plasma :
• Porter des bottes et des gants isolants et garder le corps
et les vêtements au sec.
• Ne pas se tenir, s’asseoir ou se coucher sur une surface
mouillée, ni la toucher quand on utilise le système plasma.
• S’isoler de la surface de travail et du sol en utilisant des
tapis isolants secs ou des couvertures assez grandes
pour éviter tout contact physique avec le travail ou le sol.
S’il s’avère nécessaire de travailler dans ou près d’un
endroit humide, procéder avec une extrême prudence.
• Installer un sectionneur avec fusibles appropriés, à
proximité de la source de courant. Ce dispositif permet à
l’opérateur d’arrêter rapidement la source de courant en
cas d’urgence.
• En cas d’utilisation d’une table à eau, s’assurer que cette
dernière est correctement mise à la terre.
LES CHOCS ÉLECTRIQUES PEUVENT ÊTRE FATALS
• Installer et mettre à la terre l’équipement selon les
instructions du présent manuel et conformément aux
codes électriques locaux et nationaux.
• Inspecter fréquemment le cordon d’alimentation primaire
pour s’assurer qu’il n’est ni endommagé, ni fendu.
Remplacer immédiatement un cordon endommagé.
Un câble dénudé peut tuer.
• Inspecter et remplacer les câbles de la torche qui sont
usés ou endommagés.
• Ne pas saisir la pièce à couper ni les chutes lors du
coupage. Laisser la pièce à couper en place ou sur la
table de travail, le câble de retour connecté lors du
coupage.
• Avant de vérifier, de nettoyer ou de remplacer les pièces
de la torche, couper l’alimentation ou débrancher la prise
de courant.
• Ne jamais contourner ou court-circuiter les verrouillages
de sécurité.
• Avant d’enlever le capot du système ou de la source de
courant, couper l’alimentation électrique. Attendre en
suite
5 minutes pour que les condensateurs se déchargent.
• Ne jamais faire fonctionner le système plasma sans que
les capots de la source de courant ne soient en place.
Les raccords exposés de la source de courant sont
extrêmement dangereux.
• Lors de l’installation des connexions, attacher tout d’abord
la prise de terre appropriée.
• Chaque système plasma Hypertherm est conçu pour être
utilisé uniquement avec des torches Hypertherm
spécifiques. Ne pas utiliser des torches inappropriées qui
pourraient surchauffer et présenter des risques pour la
sécurité.
Le coupage peut produire des vapeurs et des gaz toxiques
qui réduisent le niveau d’oxygène dans l’air et peuvent
provoquer des blessures, voire la mort.
• Conserver le poste de coupage bien aéré ou utiliser un
masque respiratoire homologué.
• Ne pas procéder au coupage près d’endroits où
s’effectuent le dégraissage, le nettoyage ou la vaporisation. Certains solvants chlorés se décomposent sous
l’effet des rayons ultraviolets et forment du phosgène.
• Ne pas couper des métaux peints ou contenant des
matières toxiques comme le zinc (galvanisé), le plomb, le
cadmium ou le béryllium, à moins que la zone de travail
LE COUPAGE PEUT PRODUIRE DES VAPEURS TOXIQUES
soit très bien ventilée et que l’opérateur porte un masque
respiratoire. Les revêtements et métaux contenant ces
matières peuvent produire des vapeurs toxiques lors du
coupage.
• Ne jamais couper de récipients pouvant contenir des
matières inflammables avant de les avoir vidés et
nettoyés correctement.
• Quand on utilise ce produit pour le soudage ou le
coupage, il dégage des fumées et des gaz qui
contiennent des produits chimiques qui, selon l’État de
Californie, provoquent des anomalies congénitales et,
dans certains cas, le cancer.
