ELECTROMAGNETIC COMPATIBILITY (EMC)
8-06
Hypertherm Plasma Systems i
EMC Introduction
Hypertherm’s CE-marked equipment is built in
compliance with standard EN60974-10. The
equipment should be installed and used in
accordance with the information below to achieve
electromagnetic compatibility.
The limits required by EN60974-10 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.
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
Page 5
ELECTROMAGNETIC COMPATIBILITY (EMC)
8-06
ii Hypertherm Plasma Systems
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.
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/ TS 62081 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.

SAFETY
RECOGNIZE SAFETY INFORMATION
The symbols shown in this section are
used to identify potential hazards. When you see a
safety symbol in this manual or on your machine,
understand the potential for personal injury, and
follow the related instructions to avoid the hazard.
FOLLOW SAFETY INSTRUCTIONS
Read carefully all safety messages in
this manual and safety labels on your
machine.
• Keep the safety labels on your machine in good
condition. Replace missing or damaged labels
immediately.
• Learn how to operate the machine and how to
use the controls properly. Do not let anyone
operate it without instruction.
• Keep your machine in proper working condition.
Unauthorized modifications to the machine may
affect safety and machine service life.
DANGER WARNING CAUTION
A signal word DANGER or WARNING is used with
a safety symbol. DANGER identifies the most
serious hazards.
• DANGER and WARNING safety labels are
located 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 argonhydrogen 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.
Page 14
Hypertherm Plasma Systems 1-3
8-06
SAFETY
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.

SAFETY
The plasma arc by itself is the heat source
used for cutting. Accordingly, although the
plasma arc has not been identified as a
source of toxic fumes, the material being cut
can be a source of toxic fumes or gases that
deplete oxygen.
Fumes produced vary depending on the
metal that is cut. Metals that may release
toxic fumes include, but are not limited to,
stainless steel, carbon steel, zinc
(galvanized), and copper.
In some cases, the metal may be coated
with a substance that could release toxic
fumes. Toxic coatings include, but are not
limited to, lead (in some paints), cadmium
(in some paints and fillers), and beryllium.
Gases produced by plasma cutting vary
based on the material to be cut and the
method of cutting, but may include ozone,
oxides of nitrogen, hexavalent chromium,
hydrogen, and other substances if such are
contained in or released by the material
being cut.
Caution should be taken to minimize
exposure to fumes produced by any
industrial process. Depending upon the
chemical composition and concentration of
the fumes (as well as other factors, such as
ventilation), there may be a risk of physical
illness, such as birth defects or cancer.
It is the responsibility of the equipment and
site owner to test the air quality in the area
where the equipment is used and to ensure
that the air quality in the workplace meets all
local and national standards and regulations.
The air quality level in any relevant
workplace depends on site-specific variables
such as:
TOXIC FUMES CAN CAUSE INJURY OR DEATH
• Table design (wet, dry, underwater).
• Material composition, surface finish, and
composition of coatings.
• Volume of material removed.
• Duration of cutting or gouging.
• Size, air volume, ventilation and filtration
of the work area.
• Personal protective equipment.
• Number of welding and cutting systems in
operation.
• Other site processes that may produce
fumes.
If the workplace must conform to national or
local regulations, only monitoring or testing
done at the site can determine whether the
site is above or below allowable levels.
To reduce the risk of exposure to fumes:
• Remove all coatings and solvents from the
metal before cutting.
• Use local exhaust ventilation to remove
fumes from the air.
• Do not inhale fumes. Wear an air-supplied
respirator when cutting any metal coated
with, containing, or suspected to contain
toxic elements.
• Assure that those using welding or cutting
equipment, as well as air-supplied
respiration devices, are qualified and
trained in the proper use of such
equipment.
• Never cut containers with potentially toxic
materials inside. Empty and properly clean
the container first.
• Monitor or test the air quality at the site as
needed.
• Consult with a local expert to implement a
site plan to ensure safe air quality.

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

SÉCURITÉ
L’arc plasma est lui-même la source de chaleur utilisée
pour le coupage. Par conséquent, bien que l’arc plasma
n’ait pas été reconnu comme une source de vapeurs
toxiques, le matériau coupé peut être une source de
vapeurs ou de gaz toxiques qui épuisent l’oxygène.
Les vapeurs produites varient selon le métal coupé. Les
métaux qui peuvent dégager des vapeurs toxiques
comprennent, entre autres, l’acier inoxydable, l’acier au
carbone, le zinc (galvanisé) et le cuivre.
Dans certains cas, le métal peut être revêtu d’une
substance susceptible de dégager des vapeurs toxiques.
Les revêtements toxiques comprennent entre autres, le
plomb (dans certaines peintures), le cadmium (dans
certaines peintures et enduits) et le béryllium.
Les gaz produits par le coupage plasma varient selon le
matériau à couper et la méthode de coupage, mais ils
peuvent comprendre l’ozone, les oxydes d’azote, le
chrome hexavalent, l’hydrogène et autres substances
présentes dans le matériau coupé ou en émanent.
On doit prendre les précautions qui s’imposent pour
réduire au minimum l’exposition aux vapeurs produites par
tout processus industriel. Selon la composition chimique et
la concentration des vapeurs (ainsi que d’autres facteurs
comme la ventilation), il peut y avoir un risque de maladie
physique, comme des malformations ou le cancer.
Il incombe au propriétaire du matériel et du site de vérifier
la qualité de l’air dans le secteur où l’on utilise le matériel
et de s’assurer que la qualité de l’air sur les lieux de travail
répond aux normes et réglementation locales et nationales.
LES VAPEURS TOXIQUES PEUVENT PROVOQUER
DES BLESSURES OU LA MORT
Le niveau de qualité de l’air dans tout lieu de travail
dépend des variables propres au site comme :
• Type de table (humide, sèche, sous l’eau).
• Composition du matériau, fini de la surface et
composition des revêtements.
• Volume de matériau enlevé.
• Durée du coupage ou du gougeage.
• Dimensions, volume d’air, ventilation et filtration de la
zone de travail.
• Équipement de protection individuelle.
• Nombre de systèmes de soudage et de coupage en
fonctionnement.
• Autres procédés du site qui peuvent produire des
vapeurs.
Si les lieux de travail doivent être conformes aux
règlements nationaux ou locaux, seuls les contrôles ou les
essais effectués au site peuvent déterminer si celui-ci se
situe au-dessus ou au-dessous des niveaux admissibles.
Pour réduire le risque d’exposition aux vapeurs :
• Éliminer tout revêtement et solvant du métal avant le
coupage.
• Utiliser la ventilation d’extraction locale pour éliminer les
vapeurs de l’air..
• Ne pas inhaler les vapeurs. Porter un respirateur à
adduction d’air quand on coupe des métaux revêtus
d’éléments toxiques ou qui en contiennent ou sont
susceptibles d’en contenir.
• S’assurer que les personnes qui utilisent un matériel de
soudage ou de coupage ainsi que les dispositifs de
respiration par adduction d’air sont qualifiés et ont reçu
la formation sur la bonne utilisation d’un tel matériel.
• Ne jamais couper les contenants dans lesquels il peut y
avoir des matériaux toxiques. En premier lieu, vider et
nettoyer correctement le contenant.
• Contrôler ou éprouver la qualité de l’air au site selon les
besoins.
• Consulter un expert local pour mettre en œuvre un plan
du site afin d’assurer une qualité de l’air sûre.

El arco plasma es por si solo la fuente de calor que se usa
para cortar. Según esto, aunque el arco de plasma no ha
sido identificado como la fuente de humo tóxico, el material
que se corta puede ser la fuente de humo o gases tóxicos
que vacían el oxígeno.
El humo producido varía según el metal que está
cortándose. Metales que pueden liberar humo tóxico
incluyen, pero no están limitados a, acero inoxidable,
acero al carbón, cinc (galvanizado), y cobre.
En algunos casos, el metal puede estar recubierto con una
sustancia que podría liberar humos tóxicos. Los
recubrimientos tóxicos incluyen, pero no están limitados a,
plomo (en algunas pinturas), cadmio (en algunas pinturas
y rellenos), y berilio.
Los gases producidos por el corte por plasma varían
basándose en el material a cortarse y el método de cortar,
pero pueden incluir ozono, óxidos de nitrógeno, cromo
hexavalente, hidrógeno, y otras substancias, si están
contenidas dentro o liberadas por el material que se corta.
Se debe tener cuidado de minimizar la exposición del
humo producido por cualquier proceso industrial. Según la
composición química y la concentración del humo (al igual
que otros factores, tales como ventilación), puede haber el
riesgo de enfermedad física, tal como defectos de
natividad o cáncer.
Es la responsabilidad del dueño del equipo y instalación el
comprobar la calidad de aire en el lugar donde se está
usando el equipo para garantizar que la calidad del aire en
el lugar de trabajo cumpla con todas las normas y
reglamentos locales y nacionales.
HUMOS TÓXICOS PUEDEN CAUSAR LESIONES O MUERTE
El nivel de la calidad del aire en cualquier lugar de trabajo
relevante depende en variables específicas al sitio tales
como:
• Diseño de mesa (mojada, seca, bajo agua).
• La composición del material, el acabado de la superficie,
y la composición de los recubrimientos.
• Volumen que se quita del material.
• La duración del corte o ranura.
• Tamaño, volumen del aire, ventilación y filtración del
lugar de trabajo.
• Equipo de protección personal.
• Número de sistemas de soldar y cortar en la operación.
• Otros procesos del lugar que pueden producir humo.
Si el lugar de trabajo debe cumplir reglamentos nacionales
o locales, solamente el monitoreo o las pruebas que se
hacen en el lugar pueden determinar si el sitio está encima
o debajo de los niveles permitidos.
Para reducir el riesgo de exposición a humo:
• Quite todos los recubrimientos y solventes del metal
antes de cortar.
• Use ventilación extractora local para quitar humo del
aire.
• No inhale el humo. Use un respirador con fuente propia
de aire cuando corte cualquier metal recubierto con, o
sospechado de contener, elementos tóxicos.
• Garantice que aquéllos usando equipo de soldar o
cortar, al igual que aparatos de respiración con aire
propio de aire, estén capacitados y entrenados en el uso
apropiado de tal equipo.
• Nunca corte recipientes con materiales potencialmente
tóxicos adentro. Primero, vacíe y limpie el recipiente
adecuadamente.
• Monitoree o compruebe la calidad del aire en el sitio
como fuera necesario.
• Consulte con un experto local para realizar un plan al
sitio para garantizar la calidad de aire seguro.

The Powermax1250 is a universal power supply that can configure itself to operate with AC
voltages from 200 to 600 (230-400 3PH for CE model). Use a line disconnect switch for each
power supply so that the operator can turn off the power supply quickly in an emergency.
Locate the switch so it is easily accessible to the operator. The interrupt level of the switch
must be equal to or exceed the continuous rating of the fuses. Use slow-blow fuses rated per
local and national electrical codes.
Three-phase power cord – plug installation
The Powermax1250 power supplies are shipped with an 8 AWG 4-wire power cord on
standard models. A6 mm2, 4-wire HAR power cord is provided on CE models. To operate the
Powermax1250, use a plug that meets national or local electrical codes. The plug must be
connected to the power cord by a licensed electrician.

Plasma gas supply
The gas supply for the Powermax1250 can be shop compressed air or cylinder compressed
air.A high-pressure regulator must be used on either type of supply and must be capable of
delivering gas to the filter on the power supply at 400 scfh/6.7 scfm (189 l/min), minimum flow
rate, at a minimum pressure of 90 psig (6.1 bar). If gas supply quality is poor, cut speeds
decrease, cut quality deteriorates, cutting thickness capability decreases, and parts life
shortens.
Gas supply

Firing the torch unnecessarily reduces nozzle and electrode life.
When cutting, make sure that sparks are exiting from
the bottom of the workpiece.
If sparks are spraying up from the workpiece, you are
moving the torch too fast, or without sufficient power.
Position the torch nozzle at a vertical position and watch
the arc as it cuts along the line.
Shielded consumables. Do not push down on the
torch when cutting. Lightly drag the torch across the
workpiece to maintain a steady cut.
• Pulling the torch through the cut is easier than pushing it.
• To cut thin material, reduce the amps until you get the best quality cut.
• For straight-line cuts, use a straight edge as a guide. To cut circles, use a template or
a Hypertherm circle cut guide, part number 027668.
Unshielded consumables. Maintain an approximate
1/8 inch (3 mm) torch-to-work distance.

WARNING
SPARKS AND HOT METAL CAN INJURE
EYES AND BURN SKIN
When firing the torch at an angle, sparks and hot metal will
spray out from the nozzle. Point the torch away from yourself
and others.
Piercing
Hold the torch so that the nozzle is within 1/8 inch (3 mm) from the workpiece before firing the
torch.
Fire the torch at an angle to the
workpiece, then slowly rotate it to an
upright position.
When sparks are exiting from the
bottom of the workpiece, the arc has
pierced through the material.
When the pierce is complete,
proceed with the cut.

Maximum travel speeds are the fastest travel speeds possible to cut the material without regard to cut quality.
Optimum travel speeds provide the best cut angle, least dross and best cut surface finish. Remember that cut charts
are intended to provide a good starting point for each different cut assignment. Every cutting system requires
“fine tuning” for each cutting application in order to obtain the desired cut quality.

1. The ON/OFF power switch is set to
ON ( I ), and the power ON (green)
LED is not illuminated.
1.1 The power cord is not plugged into the
power receptacle.
Plug the power cord into the receptacle.
1.2 The disconnect power switch is not set to
ON or there is no power available to the
disconnect power switch box.
Turn on the power at the main power panel or
at the disconnect power switch box.
2. The power ON (green) and gas
pressure (yellow) LEDs are
flashing and the fault (red) LED
is illuminated.
2.1 The gas supply is turned OFF or not
connected to the power supply.
Check that the gas is turned on and is
connected to the power supply.
2.2 The incoming gas pressure is too low.
Set incoming gas pressure to 90-120 psig
(6.2-8.3 bar). Check that there are no leaks in
the gas supply line.
2.3 Output gas pressure is set too low for
selected mode.
Adjust gas pressure. See Section 4 for
pressure settings.
3. The power ON, low line voltage
(yellow), and fault (red) LEDs are
illuminated.
3.1 Line voltage is too low, too high, or a
phase (CE system only) is missing.
Have a qualified technician check the
incoming power.
4. The power ON (green),
temperatue (yellow) and fault
(red) LEDs are illuminated.
4.1 One of the internal thermostat switches
has opened due to overheating or
extremely low temperature.
Leave the power supply on to allow the fan to
cool the power supply (overheating). Move
the power supply to a warm location (extreme
cold).
Note: The fan turns on and off
automatically. The fan may not
be in operation even though
the power is ON ( I ).
