ELECTROMAGNETIC COMPATIBILITY (EMC)
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.
Hypertherm Plasma Systems
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.
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
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.

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.
Hypertherm Plasma Systems
SAFETY
ELECTRIC SHOCK CAN KILL
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.
• 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
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
Hypertherm Plasma Systems
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.

SAFETY
A PLASMA ARC CAN CAUSE INJURY AND BURNS
Instant-On Torches
Plasma arc comes on immediately when the torch
switch is activated.
The plasma arc will cut quickly through gloves and
skin.
• Keep away from the torch tip.
• Do not hold metal near the cutting path.
• Never point the torch toward yourself or others.
ARC RAYS CAN BURN EYES AND SKIN
Eye Protection Plasma arc rays produce intense
visible and invisible (ultraviolet and infrared) rays that
can burn eyes and skin.
• Use eye protection in accordance with applicable
national or local codes.
• Wear eye protection (safety glasses or goggles with
side shields, and a welding helmet) with appropriate
lens shading to protect your eyes from the arc’s
ultraviolet and infrared rays.

• 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.
Hypertherm Systèmes plasma
SÉCURITÉ
LES CHOCS ÉLECTRIQUES PEUVENT ÊTRE FATALS
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.
• 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 ensuite
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 TOXIQUES
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
Hypertherm Systèmes plasma
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.

Theory of Operation
General
Refer to Functional Description, Sequence of Operation and the system wiring diagram in Section 6.
Functional Description
AC power enters the system through the power switch S1 to the input diode bridge D24. The voltage from the diode
bridge supplies the Power Factor Correction (PFC) Boost Converter which provides a 750 VDC bus voltage. The
bus voltage then supplies the inverter and the flyback system power supply (DC to DC converter) on the power
board PCB2. The power board provides noise suppression and spike protection. A "soft start" is implemented via
the power board resistor and relay K1.
The PFC Boost Converter consists of an isolated gate bipolar transistor (IGBT) Q14, choke and control circuit. It provides
a 750 VDC bus voltage when input AC voltage is between 170 and 540 VAC. When the input voltage is above 540 VAC
the bus voltage will rise to Vin* 2.
The inverter consists of an IGBT Q13, the power transformer T2, a current sense transformer, and sections of the
power board. The inverter operates as a pulse-width, modulator-controlled bridge circuit, and is rectified by the
output diode.
The output circuitry consists of 2 current transfer sensors located on the power board, the pilot arc IGBT Q15 and
the output choke.
The control board’s microprocessor monitors and regulates system operation and safety circuits. The current is set
to the desired value by adjusting the current adjustment knob. The system compares the set point to the output
current by monitoring the current sensor and adjusting the pulse width output of the inverter IGBT Q13.
The control board PCB3 includes a pilot arc control switch, allowing the operator to turn the pilot arc ON (useful
when cutting expanded metal), OFF (for maximum life of consumables), or increase the pilot arc to 30A (useful for
gouging or non-transferred-arc cutting).

WARNING
ELECTRIC SHOCK CAN KILL
• Turn off the power and remove the input power plug from its receptacle before removing
the cover from the power supply. If the power supply is directly connected to a line
disconnect box, switch the line disconnect to OFF (O). In the U.S., use a "lock-out / tagout" procedure until the service or maintenance work is complete. In other countries,
follow appropriate national or local safety procedures.
• Do not touch live electrical parts! If power is required for servicing, use extreme caution
when working near live electrical circuits. Dangerous voltages exist inside the power
supply that can cause serious injury or death.
• Do not attempt to repair the power board or control board. Do not cut away or remove
any protective conformal coating from either board. To do so will risk a short circuit
between the AC input circuit and the output circuit and may result serious injury or
death.
HOT PARTS CAN CAUSE SEVERE BURNS
• Allow the power supply to cool before servicing.
MOVING BLADES CAN CAUSE INJURY
• Keep hands away from moving parts.
STATIC ELECTRICITY CAN DAMAGE CIRCUIT BOARDS
• Put on a grounded wrist strap before handling PC boards.
Visual Inspection – Internal
1. Set the ON/OFF switch S1 to O (OFF), unplug the power cord and disconnect the gas supply.
2. Remove the cover of the power supply by removing the 18 securing screws.
3. Inspect the inside of the power supply, especially on the side with the power board. Look for broken or loose
wiring connections, burn and char marks, damaged components, etc. Repair or replace as necessary.
