1-2. Plasma Arc Cutting Hazards

The symbols shown below are used throughout this manual
to call attention to and identify possible hazards. When you
see the symbol, watch out, and follow the related instructions
to avoid the hazard. The safety information given below is
only a summary of the more complete safety information
found in the Safety Standards listed in Section 1-5. Read and
follow all Safety Standards.

Only qualified persons should install, operate, maintain, and
repair this unit.

During operation, keep everybody, especially children, away.

CUTTING can cause fire or explosion.

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.

D Remove all flammables within 35 ft (10.7 m) of the cutting arc. If this

is not possible, tightly cover them with approved covers.

D Do not cut where flying sparks can strike flammable material.
D Protect yourself and others from flying sparks and hot metal.
D Be alert that sparks and hot materials from cutting can easily go

through small cracks and openings to adjacent areas.

D Watch for fire, and keep a fire extinguisher nearby.
D Be aware that cutting on a ceiling, floor, bulkhead, or partition can

cause fire on the hidden side.

D Do not cut on closed containers such as tanks or drums.
D Connect work cable to the work as close to the cutting area as prac-

tical to prevent cutting current from traveling long, possibly unknown
paths and causing electric shock, sparks, and fire hazards.

D Do not use plasma cutter to thaw frozen pipes.
D Never cut containers with potentially flammable materials inside −

they must be emptied and properly cleaned first.

D Do not cut where the atmosphere may contain flammable dust,

gas, or liquid vapors (such as gasoline).

D Do not cut pressurized cylinders, pipes, or vessels.
D Do not cut containers that have held combustibles.
D Wear oil-free protective garments such as leather gloves, heavy

shirt, cuffless trousers, high shoes, and a cap.

D Do not locate unit on or over combustible surfaces.
D Remove any combustibles, such as a butane lighter or matches,

from your person before doing any cutting.

D After completion of work, inspect area to ensure it is free of sparks,

glowing embers, and flames.

D Use only correct fuses or circuit breakers. Do not oversize or by-

pass them.

D Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B

for hot work and have a fire watcher and extinguisher nearby.

. Indicates special instructions.

This group of symbols means Warning! Watch Out! ELECTRIC
SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult sym­bols and related instructions below for necessary actions to avoid the
hazards.

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

higher voltages than welding to start and maintain the arc (200 to 400
volts dc are common), but may 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 equip-

ment. Lockout/tagout input power according to OSHA CFR

1910.147 (see Safety Standards).

D Properly install and ground 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 conduc-

tor first.

D Keep cords dry, free of oil and grease, and protected from hot metal

and sparks.

D Frequently inspect input power cord for damage or bare wiring − re-

place cord immediately if damaged − bare wiring can kill.

D Turn off all equipment when not in use.
D Inspect and replace any worn or damaged torch cable leads.
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.

live when power is on. Plasma arc cutting requires

ELECTRIC SHOCK can kill.

FUMES AND GASES can be hazardous.

SIGNIFICANT DC VOLTAGE exists in
inverter power sources AFTER the re­moval of input power.

D Turn Off unit, disconnect input power, check voltage on input ca-

pacitors, and be sure it is near zero (0) volts before touching any
parts. Check capacitors according to instructions in Mainte­nance Section of Owner’s Manual or Technical Manual before
touching any parts.

EXPLODING PARTS can injure.

D On inverter power sources, failed parts can ex-

plode 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 Wear approved face shield or safety goggles with side shields.
D Wear proper body protection to protect skin.
D Wear flame-resistant ear plugs or ear muffs to prevent sparks from

entering ears.

ARC RAYS can burn eyes and skin.

Arc rays from the cutting process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin.

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 may 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.

D Wear approved safety glasses with side shields under your helmet

or shield.

D Use protective screens or barriers to protect others from flash, glare

and sparks; warn others not to watch the arc.

D Wear protective clothing made from durable, flame-resistant

material (leather, heavy cotton, or wool) and foot protection.

NOISE can damage hearing.

Prolonged noise from some cutting applications can
damage hearing if levels exceed limits specified by
OSHA (see Safety Standards).

D Use approved ear plugs or ear muffs if noise level is high.
D Warn others nearby about noise hazard.

OM-237 974 Page 2

Cutting produces fumes and gases. Breathing
these fumes and gases can be hazardous to
your health.

D Keep your head out of the fumes. Do not breathe the fumes.
D If inside, ventilate the area and/or use local forced ventilation at the

arc to remove cutting fumes and gases.

D If ventilation is poor, wear an approved air-supplied respirator.
D Read and understand the Material Safety Data Sheets (MSDSs)

and the manufacturer’s instruction for metals to be cut, coatings,
and cleaners.

D 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.

D Do not cut in locations near degreasing, cleaning, or spraying oper-

ations. The heat and rays of the arc can react with vapors to form
highly toxic and irritating gases.

D 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.

D 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.

PLASMA ARC can injure.

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.

D Keep away from the torch tip.
D Do not grip material near the cutting path.
D The pilot arc can cause burns − keep away from torch tip when trig-

ger is pressed.

D Wear proper flame-retardant clothing covering all exposed body ar-

eas.

D Point torch away from your body and toward work when pressing

the torch trigger − pilot arc comes on immediately.

D Turn off power source and disconnect input power before disas-

sembling torch or changing torch parts.

D Use only torch(es) specified in the Owner’s Manual.

CYLINDERS can explode if damaged.

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.

D Protect compressed gas cylinders from excessive heat, mechani-

cal shocks, physical damage, slag, open flame, sparks, and arcs.

D Install and secure cylinders in an upright position by chaining them

to a stationary support or equipment cylinder rack to prevent falling
or tipping.

D Keep cylinders away from any cutting or other electrical circuits.
D Never allow electrical contact between a plasma arc torch and a

cylinder.

D Never cut on a pressurized cylinder − explosion will result.
D Use only correct gas cylinders, regulators, hoses, and fittings de-

signed for the specific application; maintain them and associated
parts in good condition.

D Turn face away from valve outlet when opening cylinder valve.
D Keep protective cap in place over valve except when cylinder is in

use or connected for use.

D Use the right equipment, correct procedures, and sufficient number

of persons to lift and move cylinders.

D Read and follow instructions on compressed gas cylinders, asso-

ciated 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). Welding current creates an EMF field around
the welding circuit and welding equipment. EMF fields may interfere with
some medical implants, e.g. pacemakers. Protective measures for per­sons wearing medical implants have to be taken. For example, access
restrictions for passers−by or 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.

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.

D Mise sous tension, toute pièce défectueuse

des sources d’alimentation de l’inverseur peut
exploser ou faire exploser d’autres pièces.
Pour entretenir les inverseurs, toujours porter
un masque protecteur et un vêtement à man­ches longues.

LES ÉTINCELLES PROJETÉES
peuvent provoquer des blessures.

Le coupage plasma produit des étincelles et projec­tions de métal à très haute température. Lorsque la
pièce refroidit, du laitier peut se former.

D Portez une visière ou des lunettes de sécurité avec des écrans la-

téraux approuvées.

D Portez des vêtements de protection adéquats afin de protéger vo-

tre peau.

D Ayez recours à des protège−tympans ou à un serre−tête ignifuges

afin d’éviter que les étincelles n’entrent dans vos oreilles.

LES RAYONS D’ARC peuvent entraî­ner des brûlures aux yeux et à la peau.

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 Une protection faciale (casque ou masque) avec des lunettes filt-

rantes de teinte adéquate est indispensable pour protéger le
visage et les yeux des rayonnements de l’arc et des étincelles
pendant la découpe ou en regardant simplement ANSI Z49.1 (re­portez−vous aux Principales normes de sécurité) suggère
d’utiliser un filtre de teinte nd 9 (nd 8 étant le minimum) pour tout
travail de coupage faisant appel à un courant de moins de 300 A.
On mentionne également dans la norme Z49.1 qu’un filtre plus fai­ble peut être utilisé lorsque l’arc est caché par la pièce à couper.
Comme cela est habituellement le cas pour les travaux de coupage
à faible courant, les teintes énumérées au tableau 1 sont fournies à
titre d’information pour l’opérateur.

D Porter des lunettes de sécurité à coques latérales sous votre cas-

que ou écran facial.

D Ayez recours à des écrans protecteurs ou à des rideaux pour pro-

téger les autres contre les rayonnements, les étincelles et les
éblouissements; prévenez toute personne sur les lieux de ne pas
regarder l’arc.

D Portez des vêtements confectionnés avec des matières résistan-

tes et ignifuges (cuir, coton lourd ou laine) et des bottes de
protection.

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 Si vous êtes à l’intérieur au moment du coupage, ventilez la pièce

ou ayez recours à une ventilation aspirante installée près de l’arc
pour évacuer les vapeurs et les gaz.

D Si la ventilation est médiocre, utilisez un respirateur anti−vapeurs

approuvé.

D Lire et comprendre les spécifications de sécurité des matériaux

(MSDS) et les instructions du fabricant concernant les métaux, les
consommables, les revêtements, les nettoyants et les dégrais­seurs.

D Travaillez dans un espace restreint uniquement s’il est bien ventilé

ou si vous portez un respirateur anti−vapeurs. Les vapeurs cau-
sées 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.

OM-237 974 Page 6

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 galvani-

sés, 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 vi-
der et les nettoyer convenablement.

2-6. Informations relatives aux CEM

Le courant électrique qui traverse tout conducteur génère des champs
électromagnétiques (CEM) à certains endroits. Le courant de soudage
crée un CEM autour du circuit et du matériel de soudage. Les CEM
peuvent créer des interférences avec certains implants médicaux
comme des stimulateurs cardiaques. Des mesures de protection pour
les porteurs d’implants médicaux doivent être prises: par exemple, des
restrictions d’accès pour les passants ou une évaluation individuelle
des risques 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.

input power at rated frequency(+10%) and voltage (+10%). Phase to ground voltage shall not exceed +10% of rated input voltage. Do not use a genera-
tor with automatic idle device (that idles engine when no load is sensed) to supply input power to this welding power source.

6-6. Checking/Replacing Retaining Cup, Tip, And Electrode

! Overtightening will strip threads. Do not overtighten retaining cup

during assembly. Do not cross-thread parts causing stripping. Use
care during torch assembly and parts replacement.

! Inspect shield cup, tip, and electrode for wear before cutting or whenever cutting speed has been significant-

ly reduced. Do not operate torch without a tip or electrode in place. Be sure to use genuine replacement parts.

. A good practice is to replace both the tip and electrode at the same time.

! Turn Off power source before checking torch parts.

Make sure this area is clean of
any debris.

Make sure swirl ring is clean of any
debris and no holes are
obstructed.

exclusion may not apply to you. This warranty provides specific
legal rights, and other rights may be available, but may vary from
state to state.

additional warranties or remedies other than as stated herein, and
to the extent that they may not be waived, the limitations and
