From Miller to You
Thank you and congratulations on choosing Miller. Now you can get
the job done and get it done right. We know you don’t have time to do
it any other way.
That’s why when Niels Miller first started building arc welders in 1929,
he made sure his products offered long-lasting value and superior
quality. Like you, his customers couldn’t afford anything less. Miller
products had to be more than the best they could be. They had to be the
best you could buy.
Today, the people that build and sell Miller products continue the
tradition. They’re just as committed to providing equipment and service
that meets the high standards of quality and value established in 1929.
This Owner’s Manual is designed to help you get the most out of your
Miller products. Please take time to read the Safety precautions. They
will help you protect yourself against potential hazards on the worksite.
We’ve made installation and operation quick
and easy. With Miller you can count on years
of reliable service with proper maintenance.

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.

Protect yourself and others from flying sparks and hot metal.
Do not cut where flying sparks can strike flammable material.
Remove all flammables within 35 ft (10.7 m) of the cutting arc. If this
is not possible, tightly cover them with approved covers.
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 on closed containers such as tanks or drums.
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 and fire hazards.
Never cut containers with potentially flammable materials inside −
they must be emptied and properly cleaned first.
Do not cut in atmospheres containing explosive dust or vapors.
Do not cut pressurized cylinders, pipes, or vessels.
Do not cut containers that have held combustibles.
Wear oil-free protective garments 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.
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 also uses 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.

Do not touch live electrical parts.
Wear dry, hole-free insulating gloves and body protection.
Insulate yourself from work and ground using dry insulating mats or
covers big enough to prevent any physical contact with the work or
ground.
Do not touch torch parts if in contact with the work or ground.
Turn off power before checking, cleaning, or changing torch parts.
Disconnect input power before installing or servicing this equipment. Lockout/tagout input power according to OSHA CFR
1910.147 (see Safety Standards).
Properly install and ground this equipment according to its Owner’s
Manual and national, state, and local codes.
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.
When making input connections, attach proper grounding conductor first.
Frequently inspect input power cord for damage or bare wiring − replace cord immediately if damaged − bare wiring can kill.
Turn off all equipment when not in use.
Inspect and replace any worn or damaged torch cable leads.
Do not wrap torch cable around your body.
Ground the workpiece to a good electrical (earth) ground if required
by codes.
Use only well-maintained equipment. Repair or replace damaged
parts at once.
Wear a safety harness if working above floor level.
Keep all panels and covers securely in place.
Do not bypass or try to defeat the safety interlock systems.
Use only torch(es) specified in Owner’s Manual.
Keep away from torch tip and pilot arc when trigger is pressed.
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.
Insulate work clamp when not connected to workpiece to prevent
contact with any metal object.
ELECTRIC SHOCK can kill.
SIGNIFICANT DC VOLTAGE exists on
internal parts of inverter power
sources AFTER the removal of input
power.
D Turn Off unit, disconnect input power, check voltage on input capacitors, 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.
OM-2253 Page 1
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.
D
D
D
D
FLYING SPARKS can cause injury.
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.
D
D
D
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
D
D
D
Wear face protection (helmet or shield) with correct shade of filter to
protect your face and eyes 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.
Wear approved safety glasses with side shields under your helmet
or shield.
Use protective screens or barriers to protect others from flash and
glare; warn others not to watch the arc.
Wear protective clothing made from durable, flame-resistant
material (leather and wool) and foot protection.
PLASMA ARC can cause injury.

Prolonged noise from some cutting applications can
damage hearing if levels exceed limits specified by
OSHA (see Safety Standards).
D
D
Use approved ear plugs or ear muffs if noise level is high.
Warn others nearby about noise hazard.
FUMES AND GASES can be hazardous.
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.
OM-2253 Page 2
If inside, ventilate the area and/or use exhaust at the arc to remove
cutting fumes and gases.
If ventilation is poor, use an approved air-supplied respirator.
Read the Material Safety Data Sheets (MSDSs) and the manufacturer’s instruction for metals to be cut, coatings, and cleaners.
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 if necessary, while wearing an airsupplied 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.
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 proper flame-retardant clothing covering all exposed body areas.
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.
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, 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 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.
Keep protective cap in place over valve except when cylinder is in
use or connected for use.
Read and follow instructions on compressed gas cylinders, associated equipment, and CGA publication P-1 listed in Safety
Standards.

1-6. EMF Information
Considerations About Welding Or Cutting And The Effects Of Low
Frequency Electric And Magnetic Fields
Welding or cutting current, as it flows through the welding or cutting
cables, will cause electromagnetic fields. There has been and still is
some concern about such fields. However, after examining more than
500 studies spanning 17 years of research, a special blue ribbon
committee of the National Research Council concluded that: “The body
of evidence, in the committee’s judgment, has not demonstrated that
exposure to power-frequency electric and magnetic fields is a humanhealth hazard.” However, studies are still going forth and evidence
continues to be examined. Until the final conclusions of the research are
reached, you may wish to minimize your exposure to electromagnetic
fields when welding or cutting.
To reduce magnetic fields in the workplace, use the following procedures:
OM-2253 Page 4
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep cutting power source and cables as far away from operator
as practical.
5. Connect work clamp to workpiece as close to the cut as possible.
About Pacemakers:
Pacemaker wearers consult your doctor first. If cleared by your doctor,
then following the above procedures is recommended.

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 peuvcnt causer un
feu ou des brûlures. Avant de commencer à travailler, assurez-vous
que l’endroit est sécuritaire.

Protégez−vous, ainsi que toute autre personne travaillant sur les
lieux, contre les étincelles et le métal chaud.
Ne coupez pas dans un endroit où des étincelles pourraient atteindre des matières inflammables.
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.
Assurez−vous qu’aucune étincelle ni particule de métal ne peut se
glisser dans de petites fissures ou tomber dans d’autres pièces.
Afin d’éliminer tout risque de feu, soyez vigilant et gardez toujours
un extincteur à la portée de la main.
Si vous coupez sur un plafond, un plancher ou une cloison, soyez
conscient que cela peut entraîner un feu de l’autre côté.
Ne coupez pas sur un contenant fermé tel qu’un réservoir ou un bidon.
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 ou un feu.
Ne coupez jamais des contenants qui peuvent contenir des matières inflammables. Vous devez en premier lieu les vider et les
nettoyer convenablement.
Ne coupez pas dans un endroit où l’atmosphère risque de contenir
de la poussière ou des vapeurs explosives.
Ne coupez pas de bouteilles, de tuyaux ou de contenants pressurisés.
Ne coupez pas de contenants qui ont déjà reçu des combustibles.
Portez des vêtements de protection exempts d’huile tels que des
gants en cuir, une veste résistante, des pantalons sans revers, des
bottes et un casque.
Ne placez pas le poste sur une surface combustible ou au−dessus
de celle−ci.
Avant le coupage, retirez tout combustible de vos poches, par
exemple un briquet au butane ou des allumettes.
UNE DÉCHARGE ÉLECTRIQUE peut
entraîner la mort.
Le fait de toucher à une pièce électrique sous
tension peut donner une décharge fatale ou entraîner des brûlures graves. Le chalumeau et le circuit
de masse sont automatiquement actifs lorsque le
poste est sous tension. L’alimentation d’entrée et les circuits internes
de l’appareil le sont également. Le coupage au plasma d’arc exige des
tensions plus élevées que le soudage pour amorcer et maintenir l’arc
(souvent de 200 à 400 V CC), c’est pourquoi on fait appel à des
chalumeaux conçus avec un système de verrouillage sécuritaire qui
met l’appareil hors tension lorsque la capsule anti−feu est desserrée
ou si le tube touche l’électrode à l’intérieur de la buse. Un poste
incorrectement installé ou inadéquatement mis à la terre constitue un
danger.

sans trous.
Isolez−vous de la pièce à couper et du sol en utilisant des housses
ou des tapis assez grands afin d’éviter tout contact physique avec
la pièce à couper ou le sol.
Ne touchez pas aux pièces du chalumeau si vous êtes en contact
avec la pièce à couper ou le sol.
Mettez l’appareil hors tension avant d’effectuer la vérification, le
nettoyage ou le changement d’une pièce du chalumeau.
Coupez l’alimentation d’entrée avant d’installer l’appareil ou d’effectuer l’entretien. Verrouillez ou étiquetez la sortie d’alimentation
selon la norme OSHA 29 CFR 1910.147 (reportez−vous aux Principales normes de sécurité).
Installez le poste correctement et mettez-le à la terre convenablement selon les consignes du manuel de l’opérateur et les normes
nationales, provinciales et locales.
Assurez−vous que le fil de terre du cordon d’alimentation est correctement relié à la borne de terre dans la boîte de coupure ou que
la fiche du cordon est branchée à une prise correctement mise à la
terre − vous devez toujours vérifier la mise à la terre.
Avant d’effectuer les connexions d’alimentation, vous devez relier
le bon fil de terre.
Vérifiez fréquemment le cordon d’alimentation afin de vous assurer
qu’il n’est pas altéré ou à nu, remplacez−le immédiatement s’il l’est.
Un fil à nu peut entraîner la mort.
L’équipement doit être hors tension lorsqu’il n’est pas utilisé.
Vérifiez et remplacez les cosses du câble du chalumeau si elles
sont usées ou altérées.
Le câble du chalumeau ne doit pas s’enrouler autour de votre corps.
Si les normes le stipulent, la pièce à couper doit être mise à la terre.
Utilisez uniquement de l’équipement en bonne condition. Réparez
ou remplacez immédiatement toute pièce altérée.
Portez un harnais de sécurité si vous devez travailler au−dessus du
sol.
Assurez−vous que tous les panneaux et couvercles sont correctement en place.
N’essayez pas d’aller à l’encontre des systèmes de verrrouillage
de sécurité ou de les contourner.
Utilisez uniquement le ou les chalumeaux recommandés dans le
manuel de l’opérateur.
N’approchez pas le tube du chalumeau et l’arc pilote lorsque la gâchette est enfoncée.
Le câble de masse doit être pincé correctement sur la pièce à couper, métal contre métal (et non de telle sorte qu’il puisse se
détacher), ou sur la table de travail le plus près possible de la ligne
de coupage.

LE BRUIT peut endommager l’ouïe.
DÉCHARGES ÉLECTRIQUES potentiellement mortelles.
Les pièces internes des sources d’alimentation de l’inverseur ont DES
CHARGES C.C. SIGNIFICATIVES
même APRÈS coupure du courant
d’alimentation.
D Mettre l’unité hors tension, mesurer la tension des condensateurs
d’entrée et s’assurer qu’elle est pratiquement nulle avant de toucher à l’une quelconque des pièces. Mesurer cette tension conformément aux directives énoncées à la section Entretien du manuel
de l’utilisateur ou du manuel technique avant de toucher à l’une
quelconque des pièces.
Risque de blessure en cas
D’EXPLOSION DES PIÈCES.
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 VOLANTES risquent de 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 latéraux approuvées.
D Portez des vêtements de protection adéquats afin de protéger votre
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 Lorsque vous coupez ou regardez quelqu’un couper, portez un masque ou un écran facial avec le filtre approprié. La norme 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 casque
ou écran facial.
D Ayez recours à des écrans protecteurs ou à des rideaux pour protéger
les autres contre les rayonnements et les éblouissements; prévenez
toute personne sur les lieux de ne pas regarder l’arc.
D Portez des vêtements confectionnés avec des matières résistantes
et ignifuges (cuir et laine) et des bottes de protection.
OM-2253 Page 6
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 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 Veuillez lire le Material Safety Data Sheets (MSDS) et les instructions
du fabricant pour obtenir plus de renseignements sur les métaux à
couper, les enrobages et les nettoyants.
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, si nécessaire, 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.
LE PLASMA D’ARC peut entraîner
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.
D Portez des vêtements de protection adéquats qui recouvrent tout votre corps.
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 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, 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, des détendeurs, des
boyaux et des raccords conçus pour l’application déterminée. Gardez−les, ainsi que toute autre pièce associée, en bonne condition.
D Détournez votre visage du détendeur−régulateur lorsque vous ouvrez
la soupape de la bouteille.
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 Lisez et suivez les instructions sur les bouteilles de gaz comprimé,
l’équipement connexe et le dépliant P−1 de la CGA mentionné dans
les Principales normes de sécurité.

Données sur le soudage électrique et sur les effets, pour l’organisme,
des champs magnétiques basse fréquence
1
Le courant de soudage ou de coupage passant dans les câbles de puissance crée des causera des champs électromagnétiques. Il y a eu et
il y a encore un certain souci à propos de tels champs. Cependant,
après avoir examiné plus de 500 études qui ont été faites pendant une
période de recherche de 17 ans, un comité spécial ruban bleu du National Research Council a conclu: “L’accumulation de preuves, suivant le
jugement du comité, n’a pas démontré que l’exposition aux champs magnétiques et champs électriques à haute fréquence représente un
risque à la santé humaine”. Toutefois, des études sont toujours en cours
et les preuves continuent à être examinées. En attendant que les
conclusions finales de la recherche soient établies, il vous serait souhaitable de réduire votre exposition aux champs électromagnétiques
pendant le soudage ou le coupage.

5-4. Plasma Cutting System Practices
The pilot arc starts immediately
when trigger is pressed.
Always connect work clamp to a clean,
paint-free location on metal workpiece, as
close to cutting area as possible.
. Set correct air pressure for process:
70 PSI (483 kPa) for cutting,
60 PSI (414 kPa) for gouging.
DO NOT start pilot arc without cutting or
gouging as this shortens the service life
of the nozzle and electrode.
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, amperage is set too low,
or consumables are worn.
Wt
1/8 in
(3.2 mm)
When doing 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.
Ref. 803 640-A / 801 400-B / Ref. 802 878
OM-2253 Page 20
5-5. Sequence Of Cutting Operation
Connect work clamp to a clean, paint-free
location on metal workpiece, as close to
cutting area as possible.
. Set air pressure to 70 PSI (483 kPa) for cutting.
The pilot arc starts immediately
when trigger is pressed.
90°
For standard (shielded) cutting, place drag
shield on edge of metal. For non-shielded
cutting, use 1/8 in (3.2 mm) standoff distance
(dragging tip will reduce tip life).
Adjust torch speed so
sparks go thru metal and
out bottom of cut.
Raise trigger lock and press
trigger. Pilot arc starts.
Pause briefly at end of
cut before releasing trigger.
After cutting arc starts, slowly
start moving torch across metal.
Postflow continues for approx. 20 seconds
after releasing trigger; cutting arc can be
instantly restarted during postflow by raising
trigger lock and pressing trigger.

OM-2253 Page 21
5-6. Sequence Of Gouging Operation
Connect work clamp to a clean, paint-free
location on workpiece, as close to cutting
area as possible.
. Set air pressure to 60 PSI (414 kPa) for gouging.
The pilot arc starts immediately
when trigger is pressed.
455
Hold torch at approximately
45° angle to workpiece.
Raise trigger lock and press trigger. Pilot
arc starts. Move tip to within approximately 3/16 in (4.8 mm). Start gouging
across workpiece surface. Maintain
approximately a 45° angle to surface.
Release trigger. Postflow continues for
approx. 20 seconds after releasing trigger;
arc can be instantly restarted during postflow
by raising trigger lock and pressing trigger.

approximately 90° to surface.
When arc has pierced through
workpiece, start cutting.
Maintain approximately 90° torch

7-4. Checking/Replacing Retaining Cup, Tip, And Electrode
Overtightening will strip threads. Do not overtighten electrode, tip,
and 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 significantly
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.
