Hot metal and sparks blow out from the cutting arc.
The flying sparks and hot metal, hot workpiece, and
hot equipment can cause fires and burns. Check
and be sure the area is safe before doing any cutting.
Remove all flammables within 35 ft (10.7 m) of the cutting arc. If this
is not possible, tightly cover them with approved covers.
Do not cut where flying sparks can strike flammable material.
Protect yourself and others from flying sparks and hot metal.
Be alert that sparks and hot materials from cutting can easily go
through small cracks and openings to adjacent areas.
Watch for fire, and keep a fire extinguisher nearby.
Be aware that cutting on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
Do not cut or weld on tire rims or wheels. Tires can explode if heated.
Repaired rims and wheels can fail. See OSHA 29 CFR 1910.177
listed in Safety Standards.
Do not cut on containers that have held combustibles, or on closed containers such as tanks, drums, or pipes unless they are properly
prepared according to AWS F4.1 and AWS A6.0 (see Safety Standards).
Connect work cable to the work as close to the cutting area as practical to prevent cutting current from traveling long, possibly unknown
paths and causing electric shock, sparks, and fire hazards.
Do not use plasma cutter to thaw frozen pipes.
Never cut containers with potentially flammable materials inside −
they must be emptied and properly cleaned first.
Do not cut where the atmosphere can contain flammable dust, gas,
or liquid vapors (such as gasoline).
Do not cut pressurized cylinders, pipes, or vessels.
Wear body protection made from durable, flame−resistant material
(leather, heavy cotton, wool). Body protection includes oil-free
clothing such as leather gloves, heavy shirt, cuffless trousers, high
shoes, and a cap.
Do not locate unit on or over combustible surfaces.
Remove any combustibles, such as a butane lighter or matches,
from your person before doing any cutting.

After completion of work, inspect area to ensure it is free of sparks,
glowing embers, and flames.
Use only correct fuses or circuit breakers. Do not oversize or bypass them.
Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B
for hot work and have a fire watcher and extinguisher nearby.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The torch and work circuit are
electrically live whenever the output is on. The input
power circuit and machine internal circuits are also
live when power is on. Plasma arc cutting requires
higher voltages than welding to start and maintain the arc (200 to 400
volts dc are common), but can also use torches designed with safety
interlock systems which turn off the machine when the shield cup is
loosened or if tip touches electrode inside the nozzle. Incorrectly
installed or improperly grounded equipment is a hazard.
D Do not touch live electrical parts.
D Wear dry, hole-free insulating gloves and body protection.
D Insulate yourself from work and ground using dry insulating mats or
covers big enough to prevent any physical contact with the work or
ground.
D Do not touch torch parts if in contact with the work or ground.
D Turn off power before checking, cleaning, or changing torch parts.
D Disconnect input power before installing or servicing this equipment. Lockout/tagout input power according to OSHA CFR
1910.147 (see Safety Standards).
D Properly install, ground, and operate this equipment according to its
Owner’s Manual and national, state, and local codes.
D Check and be sure that input power cord ground wire is properly
connected to ground terminal in disconnect box or that cord plug is
connected to a properly grounded receptacle outlet − always verify
the supply ground.
D When making input connections, attach proper grounding conductor first.
D Keep cords dry, free of oil and grease, and protected from hot metal
and sparks.
D Frequently inspect input power cord and ground conductor for damage
or bare wiring – replace immediately if damaged – bare wiring can kill.
D Turn off all equipment when not in use.
D Do not use worn, damaged, undersized, or repaired cables.
D Do not wrap torch cable around your body.
D Ground the workpiece to a good electrical (earth) ground if required
by codes.
D Use only well-maintained equipment. Repair or replace damaged
parts at once.
D Wear a safety harness if working above floor level.
D Keep all panels and covers securely in place.
D Do not bypass or try to defeat the safety interlock systems.
D Use only torch(es) specified in Owner’s Manual.
D Keep away from torch tip and pilot arc when trigger is pressed.
D Clamp work cable with good metal-to-metal contact to workpiece (not
piece that will fall away) or worktable as near the cut as practical.
D Insulate work clamp when not connected to workpiece to prevent
contact with any metal object.
OM-264259 Page 1
FUMES AND GASES can be hazardous.
ELECTRIC SHOCK can kill.
SIGNIFICANT DC VOLTAGE exists in
inverter power sources AFTER the removal of input power.
D Turn off unit, disconnect input power, and discharge input capacitors according to instructions in Manual before touching any parts.
EXPLODING PARTS can injure.
D On inverter power sources, failed parts can explode or cause other parts to explode when
power is applied. Always wear a face shield
and long sleeves when servicing inverters.
FLYING SPARKS can injure.
Sparks and hot metal blow out from the cutting arc.
Chipping and grinding cause flying metal.
D
D
D
Wear approved face shield or safety goggles with side shields.
Wear proper body protection to protect skin.
Wear flame-resistant ear plugs or ear muffs to prevent sparks from
entering ears.
Cutting produces fumes and gases. Breathing
these fumes and gases can be hazardous to
your health.

ARC RAYS can burn eyes and skin.
PLASMA ARC can injure.
Arc rays from the cutting process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin.
D
D
D
D
Wear face protection (helmet or shield) with a proper shade of filter
lenses to protect your face and eyes from arc rays and sparks when
cutting or watching. ANSI Z49.1 (see Safety Standards) suggests a
No. 9 shade (with No. 8 as minimum) for all cutting currents less
than 300 amperes. Z49.1 adds that lighter filter shades can be used
when the arc is hidden by the workpiece. As this is normally the case
with low current cutting, the shades suggested in Table 1 are provided for the operator’s convenience.
Wear approved safety glasses with side shields under your helmet
or shield.
Use protective screens or barriers to protect others from flash, glare
and sparks; warn others not to watch the arc.
Wear body protection made from durable, flame−resistant material
(leather, heavy cotton, wool). Body protection includes oil-free
clothing such as leather gloves, heavy shirt, cuffless trousers, high
shoes, and a cap.

The heat from the plasma arc can cause serious
burns. The force of the arc adds greatly to the burn
hazard. The intensely hot and powerful arc can
quickly cut through gloves and tissue.
Keep away from the torch tip.
Do not grip material near the cutting path.
The pilot arc can cause burns − keep away from torch tip when trigger is pressed.
Wear body protection made from durable, flame−resistant material
(leather, heavy cotton, wool). Body protection includes oil-free
clothing such as leather gloves, heavy shirt, cuffless trousers, high
shoes, and a cap.
Point torch away from your body and toward work when pressing
the torch trigger − pilot arc comes on immediately.
Turn off power source and disconnect input power before disassembling torch or changing torch parts.
Use only torch(es) specified in the Owner’s Manual.
CYLINDERS can explode if damaged.

Keep your head out of the fumes. Do not breathe the fumes.
Ventilate the work area and/or use local forced ventilation at the arc
to remove welding fumes and gases. The recommended way to determine adequate ventilation is to sample for the composition and
quantity of fumes and gases to which personnel are exposed.
If ventilation is poor, wear an approved air-supplied respirator.
Read and understand the Safety Data Sheets (SDSs) and the manufacturer’s instructions for adhesives, coatings, cleaners,
consumables, coolants, degreasers, fluxes, and metals.
Work in a confined space only if it is well ventilated, or while wearing
an air-supplied respirator. Fumes from cutting and oxygen depletion
can alter air quality causing injury or death. Be sure the breathing air
is safe.
Do not cut in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react with vapors to form
highly toxic and irritating gases.
Do not cut on coated metals, such as galvanized, lead, or cadmium
plated steel, unless the coating is removed from the cutting area, the
area is well ventilated, and while wearing an air-supplied respirator.
The coatings and any metals containing these elements can give off
toxic fumes when cut.
Do not cut containers with toxic or reactive materials inside or
containers that have held toxic or reactive materials − they must be
emptied and properly cleaned first.
Compressed gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode. Since
gas cylinders are normally part of metalworking processes, be sure to treat them carefully.
Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flame, sparks, and arcs.
Install and secure cylinders in an upright position by chaining them
to a stationary support or equipment cylinder rack to prevent falling
or tipping.
Keep cylinders away from any cutting or other electrical circuits.
Never allow electrical contact between a plasma arc torch and a
cylinder.
Never cut on a pressurized cylinder − explosion will result.
Use only correct compressed gas cylinders, regulators, hoses, and
fittings designed for the specific application; maintain them and associated parts in good condition.
Turn face away from valve outlet when opening cylinder valve. Do
not stand in front of or behind the regulator when opening the valve.
Keep protective cap in place over valve except when cylinder is in
use or connected for use.
Use the proper equipment, correct procedures, and sufficient number of persons to lift, move, and transport cylinders.
Read and follow instructions on compressed gas cylinders, associated equipment, and Compressed Gas Association (CGA)
publication P-1 listed in Safety Standards.

1-6. EMF Information
Electric current flowing through any conductor causes localized electric
and magnetic fields (EMF). The current from arc welding (and allied processes including spot welding, gouging, plasma arc cutting, and
induction heating operations) creates an EMF field around the welding
circuit. EMF fields can interfere with some medical implants, e.g. pacemakers. Protective measures for persons wearing medical implants
have to be taken. For example, restrict access for passers−by or conduct individual risk assessment for welders. All welders should use the
following procedures in order to minimize exposure to EMF fields from
the welding circuit:
1. Keep cables close together by twisting or taping them, or using a
cable cover.
2. Do not place your body between welding cables. Arrange cables
to one side and away from the operator.
3. Do not coil or drape cables around your body.
OM-264259 Page 4
4. Keep head and trunk as far away from the equipment in the welding circuit as possible.
5. Connect work clamp to workpiece as close to the weld as
possible.
6. Do not work next to, sit or lean on the welding power source.
7. Do not weld whilst carrying the welding power source or wire
feeder.
About Implanted Medical Devices:
Implanted Medical Device wearers should consult their doctor and the
device manufacturer before performing or going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating operations.
If cleared by your doctor, then following the above procedures is recommended.

le travail ou le projet et a reçu une formation en sécurité afin
de reconnaître et d’éviter les risques inhérents.
Au cours de l’utilisation, tenir toute personne à l’écart et plus
particulièrement les enfants.
LE COUPAGE présente un risque de
feu ou d’explosion.
Des particules de métal chaud et des étincelles
peuvent jaillir de la pièce au moment du coupage.
Les étincelles et le métal chaud, la pièce à couper
chauffée et l’équipement chaud peuvent causer un
feu ou des brûlures. Avant de commencer à travailler, assurez-vous
que l’endroit est sécuritaire.
D Déplacez toute matière inflammable se trouvant à l’intérieur d’un
périmètre de 10,7 m (35 pi) de la pièce à couper. Si cela est
impossible, vous devez les couvrir avec des housses approuvées
et bien ajustées.
D Ne coupez pas dans un endroit où des étincelles pourraient
atteindre des matières inflammables.
D Protégez−vous, ainsi que toute autre personne travaillant sur les
lieux, contre les étincelles et le métal chaud.
D Assurez−vous qu’aucune étincelle ni particule de métal ne peut se
glisser dans de petites fissures ou tomber dans d’autres pièces.
D Afin d’éliminer tout risque de feu, soyez vigilant et gardez toujours
un extincteur à la portée de la main.
D Si vous coupez sur un plafond, un plancher ou une cloison, soyez
conscient que cela peut entraîner un feu de l’autre côté.
D Ne pas couper ou souder des jantes ou des roues. Les pneus
peuvent exploser s’ils sont chauffés. Les jantes et les roues
réparées peuvent défaillir. Voir OSHA 29 CFR 1910.177 énuméré
dans les normes de sécurité.
D Ne pas effectuer le soudage sur des conteneurs fermés tels que
des réservoirs, tambours, ou conduites, à moins qu’ils n’aient été
préparés correctement conformément à AWS F4.1 et AWS A6.0
(voir les Normes de Sécurité).
D Fixez le câble de masse sur la pièce à couper, le plus près possible
de la zone à couper afin de prévenir que le courant de coupage ne
prenne une trajectoire inconnue ou longue et ne cause ainsi une
décharge électrique, d’étincelles ou un feu.
D Ne pas utiliser le coupeur plasma pour dégeler des conduites
gelées.
D Ne coupez jamais des contenants qui peuvent contenir des
matières inflammables. Vous devez en premier lieu les vider et les
nettoyer convenablement.
D Ne pas couper là où l’air ambiant pourrait contenir des poussières,
gaz ou émanations inflammables (vapeur d’essence, par
exemple).
D Ne coupez pas de bouteilles, de tuyaux ou de contenants
pressurisés.
D Porter un équipement de protection pour le corps fait d’un matériau
résistant et ignifuge (cuir, coton robuste, laine). La protection du
corps comporte des vêtements sans huile comme par ex. des
gants de cuir, une chemise solide, des pantalons sans revers, des
chaussures hautes et une casquette.
D Ne placez pas le poste sur une surface combustible ou au−dessus
de celle−ci.
D Avant le coupage, retirez tout combustible de vos poches, par
exemple un briquet au butane ou des allumettes.
D Une fois le travail achevé, assurez−vous qu’il ne reste aucune
trace d’étincelles incandescentes ni de flammes.
D Utiliser exclusivement des fusibles ou coupe−circuits appropriés.
Ne pas augmenter leur puissance; ne pas les ponter.
D Suivre les consignes de OSHA 1910.252 (a) (2) (iv) et de NFPA
51B pour travaux de soudage et prévoir un détecteur d incendie et
un extincteur à proximité.
UN CHOC ÉLECTRIQUE peut tuer.
Le contact avec des pièces électriques sous tension
peut causer un choc fatal ou des brûlures graves.
Dès que la sortie de soudage est activée, la torche et
le circuit de travail sont sous tension. Le découpage
à l’arc sous plasma demande une tension départ et
de travail plus élevée que le soudage (typiquement, 200 et 400 V c.c.),
mais permet l’utilisation d’une torche à inter−verrouillage de sécurité
qui coupe l’alimentation de la machine lorsque la coupelle d’écran est
déposée ou si le bec de contact touche l’électrode à l’intérieur de la
buse. Des équipements mal installés ou dont la mise à la masse est
fautive constituent des dangers.

OM-264259 Page 6
Les rayons d’arc provenant du procédé de coupage
produisent des rayons visibles et invisibles intenses
(ultraviolets et infrarouges) qui peuvent entraîner
des brûlures aux yeux et à la peau.
D
Porter un protecteur facial (casque ou écran) muni d’un filtre de
teinte appropriée pour protéger le visage et les yeux des rayons et
des étincelles quand on coupe ou observe le travail de coupe. Pour
tous les courants de coupe inférieurs à 300 ampères, la norme ANSI Z49.1 (voir section Normes de sécurité) recommande une
opacité de grade 9 (grade minimum de 8). Cette norme ajoute qu’un
filtre plus pâle peut être utilisé si l’arc est caché par la pièce. Comme
c’est normalement le cas pour le coupage à faible courant, les opacités de filtres suggérées au Tableau 1 sont à la disposition de
l’opérateur au besoin.
D Porter des lunettes de sécurité à coques latérales sous votre
casque ou écran facial.
D Ayez recours à des écrans protecteurs ou à des rideaux pour
protéger les autres contre les rayonnements, les étincelles et les
éblouissements; prévenez toute personne sur les lieux de ne pas
regarder l’arc.
D Porter un équipement de protection pour le corps fait d’un matériau
résistant et ignifuge (cuir, coton robuste, laine). La protection du
corps comporte des vêtements sans huile comme par ex. des
gants de cuir, une chemise solide, des pantalons sans revers, des
chaussures hautes et une casquette.

LE BRUIT peut endommager l’ouïe.
Certaines applications de coupage produisent un
bruit constant, ce qui peut endommager l’ouïe si le
niveau sonore dépasse les limites permises par
l’OSHA (reportez−vous aux Principales normes de
sécurité).
D Utilisez des protège−tympans ou un serre−tête antibruit si le
niveau sonore est élevé.
D Prévenez toute personne sur les lieux du danger relié au bruit.
LES FUMÉES ET LES GAZ peuvent
être dangereux.
Le coupage produit des vapeurs et des gaz.
Respirer ces vapeurs et ces gaz peut être
dangereux pour la santé.
D Ne mettez pas votre tête au−dessus des vapeurs. Ne respirez pas
ces vapeurs.
D À l’intérieur, ventiler la zone et/ou utiliser une ventilation forcée au
niveau de l’arc pour l’évacuation des fumées et des gaz de
soudage. Pour déterminer la bonne ventilation, il est recommandé
de procéder à un prélèvement pour la composition et la quantité de
fumées et de gaz auxquelles est exposé le personnel.
D Si la ventilation est médiocre, utilisez un respirateur anti−vapeurs
approuvé.
D Lire et comprendre les fiches de données de sécurité et les
instructions du fabricant concernant les adhésifs, les revêtements,
les nettoyants, les consommables, les produits de
refroidissement, les dégraisseurs, les flux et les métaux.
D Travaillez dans un espace restreint uniquement s’il est bien ventilé
ou si vous portez un respirateur anti−vapeurs. Les vapeurs
causées par le coupage et l’épuisement de l’oxygène peuvent
altérer la qualité de l’air et entraîner des blessures ou la mort.
Assurez−vous que l’air ambiant est sain pour la santé.
D Ne coupez pas dans un endroit près d’opérations de décapage, de
nettoyage ou de vaporisation. La chaleur et les rayons d’arc
peuvent réagir avec les vapeurs et former des gaz hautement
toxiques et irritants.
D Ne coupez pas des métaux enrobés tels que des métaux
galvanisés, contenant du plomb ou de l’acier plaqué au cadmium, à
moins que l’enrobage ne soit ôté de la surface du métal à couper,
que l’endroit où vous travaillez ne soit bien ventilé, ou que vous ne
portiez un respirateur anti−vapeurs. Les enrobages ou tous
métaux qui contiennent ces éléments peuvent créer des vapeurs
toxiques s’ils sont coupés.
D Ne coupez pas de contenants qui renferment ou ont renfermés des
matières toxiques ou réactives − vous devez en premier lieu les
vider et les nettoyer convenablement.
L’ARC PLASMA peut provoquer des
blessures.
La chaleur dégagée par le plasma d’arc peut
entraîner de sérieuses brûlures. La force de l’arc est
un facteur qui s’ajoute au danger de brûlures. La
chaleur intense et la puissance de l’arc peuvent
rapidement passer au travers de gants et de tissus.
D N’approchez pas le tube du chalumeau.
D Ne saisissez pas la pièce à couper près de la ligne de coupage.
D L’arc pilote peut causer des brûlures − n’approchez pas le tube du
chalumeau lorsque vous avez appuyé sur le gâchette.
corps comporte des vêtements sans huile comme par ex. des
gants de cuir, une chemise solide, des pantalons sans revers, des
chaussures hautes et une casquette.
D Ne pointez pas le chalumeau en direction de votre corps ni de la
pièce à couper lorsque vous appuyez sur la gâchette − l’arc pilote
s’allume automatiquement.
D Mettez l’alimentation hors tension et débranchez le cordon
d’alimentation avant de démonter le chalumeau ou de changer une
pièce du chalumeau.
D Utilisez uniquement le ou les chalumeaux recommandés dans le
manuel de l’opérateur.
LES BOUTEILLES peuvent exploser
si elles sont endommagées.
Les bouteilles de gaz comprimé contiennent du gaz
sous haute pression. Si une bouteille est
endommagée, elle peut exploser. Puisque les
bouteilles de gaz font habituellement partie d’un
processus de travail des métaux, assurez−vous de les manipuler
correctement.
D Protégez les bouteilles de gaz comprimé contre la chaleur
excessive, les chocs mécaniques, des dommages physiques, le
laitier, la flamme, les étincelles et l’arc.
D Installez et attachez les bouteilles dans la position verticale à l’aide
d’une chaîne, sur un support stationnaire ou un châssis
porte−bouteille afin de prévenir qu’elles ne tombent ou ne
basculent.
D Les bouteilles ne doivent pas être près de la zone de coupage ni de
tout autre circuit électrique.
D Un contact électrique ne doit jamais se produire entre un
chalumeau de plasma d’arc et une bouteille.
D Ne coupez jamais sur une bouteille pressurisée − une explosion en
résulterait.
D Utilisez uniquement des bouteilles de gaz comprimé , des
détendeurs, des boyaux et des raccords conçus pour l’application
déterminée. Gardez−les, ainsi que toute autre pièce associée, en
bonne condition.
D Tourner le dos à la sortie de vanne lors de l’ouverture de la vanne
de la bouteille. Ne pas se tenir devant ou derrière le régulateur lors
de l’ouverture de la vanne.
D Le couvercle du détendeur doit toujours être en place, sauf lorsque
vous utilisez la bouteille ou qu’elle est reliée pour usage ultérieur.
D Utilisez les équipements corrects, les bonnes procédures et
suffisamment de personnes pour soulever, déplacer et transporter
les bouteilles.

2-6. Informations relatives aux CEM
Le courant électrique qui traverse tout conducteur génère des champs
électromagnétiques (CEM) à certains endroits. Le courant issu d’un
soudage à l’arc (et de procédés connexes, y compris le soudage par
points, le gougeage, le découpage plasma et les opérations de
chauffage par induction) crée un champ électromagnétique (CEM)
autour du circuit de soudage. Les champs électromagnétiques produits
peuvent causer interférence à certains implants médicaux, p. ex. les
stimulateurs cardiaques. Des mesures de protection pour les porteurs
d’implants médicaux doivent être prises: Limiter par exemple tout accès
aux passants ou procéder à une évaluation des risques individuels pour
les soudeurs. Tous les soudeurs doivent appliquer les procédures
suivantes pour minimiser l’exposition aux CEM provenant du circuit de
soudage:
1. Rassembler les câbles en les torsadant ou en les attachant avec
du ruban adhésif ou avec une housse.
2. Ne pas se tenir au milieu des câbles de soudage. Disposer les
câbles d’un côté et à distance de l’opérateur.
3. Ne pas courber et ne pas entourer les câbles autour de votre
corps.
4. Maintenir la tête et le torse aussi loin que possible du matériel du
circuit de soudage.
5. Connecter la pince sur la pièce aussi près que possible de la
soudure.
6. Ne pas travailler à proximité d’une source de soudage, ni
s’asseoir ou se pencher dessus.
7. Ne pas souder tout en portant la source de soudage ou le
dévidoir.
En ce qui concerne les implants médicaux :
Les porteurs d’implants doivent d’abord consulter leur médecin avant de
s’approcher des opérations de soudage à l’arc, de soudage par points,
de gougeage, du coupage plasma ou de chauffage par induction. Si le
médecin approuve, il est recommandé de suivre les procédures
précédentes.

Cut/Gouge Switch
Place switch in appropriate position for desired process. Unit will automatically regulate pressure to 75 psi (517 kPa) for cutting
and 60 psi (413 kPa) for gouging. Pilot current is automatically increased in gouge
mode to provide better gouging starts.
. Use only clean, dry air with 90 to 120 psi
(621 to 827 kPa) pressure. Prevent
moisture from entering air supply at
extreme cold temperatures.
. Use filter kit 300491 or 228926 where
conditions at the work site allow moisture, oil or other particulates into the air
line.

DO NOT start pilot arc without cutting or
gouging as this shortens the service life
of the nozzle and electrode.
. Connect work clamp to portion of workpiece
that does not fall away after being cut.
90°
Maintain approximately a 90° angle to the
workpiece surface for proper cutting results.
Sparks should pass through the workpiece
and out the bottom when cutting.
If sparks flare back from surface, this
usually is an indication that either travel
speed is too fast or amperage is set too low.

When doing extended (non-shielded)
cutting, maintain approximately 1/8 in.
standoff between electrode and surface.
DO NOT put pressure on shield when
drag cutting; instead, slide shield along
the surface for proper cutting results.
Pulling rather than pushing the torch
makes cutting easier. Use a proper guide
or template for accurate cutting operations.

Without concern for cut appearance, the fastest speed for cutting material is the maximum cut speed. For better cut angle, less dross, and cut surface
appearance, use the optimum cut speed. The values in the cut charts are basic starting points and each application may require some adjustment to
achieve the best cut characteristics.
