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 Principal Safety Standards. Read and follow all Safety Standards.

Only qualified persons should install, operate, maintain, and repair this equipment. A qualified person is defined as one who, by possession of a recognized degree, certificate, or professional standing, or who by extensive knowledge, training and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter, the work, or the project and has received safety training to recognize and avoid the hazards involved.

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,

Check and be sure the area is safe before doing any cutting.

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

this is not possible, tightly cover them with approved covers.

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

through small cracks and openings to adjacent areas.

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

cause fire on the hidden side.

l 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.

l 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 (see Safety Standards).

l 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.

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

they must be emptied and properly cleaned first.

l Do not cut where the atmosphere can contain flammable dust,

gas, or liquid vapors (such as gasoline).

l Do not cut pressurized cylinders, pipes, or vessels.

and hot equipment can cause fires and burns.

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 these hazards.

l Wear body protection made from leather or flame-resistant cloth-

ing (FRC). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap.

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

from your person before doing any cutting.

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

glowing embers, and flames.

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

pass them.

l 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.

l Do not touch live electrical parts. l Wear dry, hole-free insulating gloves and body protection. l Insulate yourself from work and ground using dry insulating mats

or covers big enough to prevent any physical contact with the work or ground.

l Do not touch torch parts if in contact with the work or ground. l Turn off power before checking, cleaning, or changing torch parts. l Disconnect input power before installing or servicing this equip-

ment. Lockout/tagout input power according to OSHA CFR

1910.147 (see Safety Standards).

l Properly install, ground, and operate this equipment according to

its Owner’s Manual and national, state, and local codes.

l 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.

l When making input connections, attach proper grounding conduc-

tor first—double-check connections.

l Keep cords dry, free of oil and grease, and protected from hot met-

al and sparks.

l Frequently inspect input power cord and ground conductor for

damage or bare wiring — replace immediately if damaged — bare wiring can kill.

l Turn off all equipment when not in use.

OM-254449 Page 1

Page 6

l Do not use worn, damaged, undersized, or repaired cables. l Do not wrap torch cable around your body. l Ground the workpiece to a good electrical (earth) ground if re-

quired by codes.

l Use only well-maintained equipment. Repair or replace damaged

parts at once.

l Wear a safety harness if working above floor level. l Keep all panels and covers securely in place. l Do not bypass or try to defeat the safety interlock systems. l Use only torch(es) specified in Owner’s Manual. l Keep away from torch tip and pilot arc when trigger is pressed. l 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.

l Insulate work clamp when not connected to workpiece to prevent

contact with any metal object.

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.

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.

l Wear approved safety glasses with side shields under your helmet

or shield.

l Use protective screens or barriers to protect others from flash,

glare and sparks; warn others not to watch the arc.

l Wear body protection made from leather or flame-resistant cloth-

ing (FRC). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap.

l Wear face protection (helmet or shield) with a

Table 1. Eye Protection For Plasma Arc Cutting

FLYING SPARKS can injure.

Sparks and hot metal blow out from the cutting arc. Chipping and grinding cause flying metal.

l Wear approved face shield or safety goggles with

side shields.

l Wear proper body protection to protect skin. l Wear flame-resistant ear plugs or ear muffs to prevent sparks from

entering ears.

NOISE can damage hearing.

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

l Use approved ear plugs or ear muffs if noise level

is high.

l 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.

l Keep your head out of the fumes. Do not breathe the fumes. l 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.

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

manufacturer’s instructions for adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals.

l Work in a confined space only if it is well ventilated, or while wear-

ing 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.

l Do not cut in locations near degreasing, cleaning, or spraying op-

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

l Do not cut on coated metals, such as galvanized, lead, or cadmi-

um 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.

l Do not cut containers with toxic or reactive materials inside or con-

tainers that have held toxic or reactive materials - they must be emptied and properly cleaned first.

OM-254449 Page 2

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.

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

ger is pressed.

l Wear body protection made from leather or flame-resistant cloth-

ing (FRC). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap.

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

the torch trigger—pilot arc comes on immediately.

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

sembling torch or changing torch parts.

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

CYLINDERS can explode if

damaged.

Compressed gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Since gas cylinders are normally part of metal-

working processes, be sure to treat them carefully.

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-254449 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.

L’installation, l’utilisation, l’entretien et les réparations ne doivent être confiés qu’à des personnes qualifiées. Une personne qualifiée est définie comme celle qui, par la possession d’un diplôme reconnu, d’un certificat ou d’un statut professionnel, ou qui, par une connaissance, une formation et une expérience approfondies, a démontré avec succès sa capacité à résoudre les problèmes liés à la tâche, 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.

chauffée et l’équipement chaud peuvent causer un feu ou des brûlures. Avant de commencer à travailler, assurez-vous que l’endroit est sécuritaire.

l 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.

l Ne coupez pas dans un endroit où des étincelles pourraient attein-

dre des matières inflammables.

l Protégez-vous, ainsi que toute autre personne travaillant sur les

lieux, contre les étincelles et le métal chaud.

l Assurez-vous qu’aucune étincelle ni particule de métal ne peut se

glisser dans de petites fissures ou tomber dans d’autres pièces.

l Afin d’éliminer tout risque de feu, soyez vigilant et gardez toujours

un extincteur à la portée de la main.

l Si vous coupez sur un plafond, un plancher ou une cloison, soyez

conscient que cela peut entraîner un feu de l’autre côté.

l Ne pas couper ou souder des jantes ou des roues. Les pneus peu-

vent 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.

Les étincelles et le métal chaud, la pièce à couper

Ce groupe de symboles veut dire Avertissement! Attention! DANGER DE CHOC ELECTRIQUE, PIECES EN MOUVEMENT, et PIECES CHAUDES. Reportez-vous aux symboles et aux directives cidessous afin de connaître les mesures à prendre pour éviter tout danger.

l 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 (voir les Normes de Sécurité).

l Fixez le câble de masse sur la pièce à couper, le plus près pos-

sible 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.

l Ne pas utiliser le coupeur plasma pour dégeler des conduites

gelées.

l Ne coupez jamais des contenants qui peuvent contenir des matiè-

res inflammables. Vous devez en premier lieu les vider et les nettoyer convenablement.

l Ne pas couper là où l’air ambiant pourrait contenir des poussières,

gaz ou émanations inflammables (vapeur d’essence, par exemple).

l Ne coupez pas de bouteilles, de tuyaux ou de contenants

pressurisés.

l Porter une protection corporelle en cuir ou des vêtements ignifu-

ges (FRC). 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.

l Ne placez pas le poste sur une surface combustible ou au-dessus

de celle-ci.

l Avant le coupage, retirez tout combustible de vos poches, par

exemple un briquet au butane ou des allumettes.

l Une fois le travail achevé, assurez-vous qu’il ne reste aucune

trace d’étincelles incandescentes ni de flammes.

l Utiliser exclusivement des fusibles ou coupe-circuits appropriés.

Ne pas augmenter leur puissance; ne pas les ponter.

l 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-254449 Page 5

Page 10

l Ne touchez pas aux pièces électriques sous tension. l Portez des gants isolants et des vêtements de protection secs et

sans trous.

l 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.

l Ne touchez pas aux pièces du chalumeau si vous êtes en contact

avec la pièce à couper ou le sol.

l Mettez l’appareil hors tension avant d’effectuer la vérification, le

nettoyage ou le changement d’une pièce du chalumeau.

l Coupez l’alimentation d’entrée avant d’installer l’appareil ou d’ef-

fectuer l’entretien. Verrouillez ou étiquetez la sortie d’alimentation selon la norme OSHA 29 CFR 1910.147 (reportez-vous aux Principales normes de sécurité).

l Installer le poste correctement et le mettre à la terre convenable-

ment selon les consignes du manuel de l’opérateur et les normes nationales, départementales et locales.

l Assurez-vous que le fil de terre du cordon d’alimentation est cor-

rectement 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.

l En effectuant les raccordements d’entrée fixer d’abord le conduc-

teur de mise à la terre approprié et contre-vérifier les connexions.

l Les câbles doivent être exempts d’humidité, d’huile et de graisse;

protégez-les contre les étincelles et les pièces métalliques chaudes.

l Vérifier fréquemment le cordon d’alimentation et le conducteur de

mise à la terre afin de s’assurer qu’il n’est pas altéré ou dénudé. Le remplacer immédiatement s’il l’est . Un fil dénudé peut entraîner la mort.

l L’équipement doit être hors tension lorsqu’il n’est pas utilisé. l Ne pas utiliser des câbles usés, endommagés, sous dimension-

nés ou réparés.

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.

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

téraux approuvées.

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

tre peau.

l Ayez recours à des protège-tympans ou à un serre-tête ignifuges

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

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

sécurité).

l Utilisez des protège-tympans ou un serre-tête antibruit si le niveau

sonore est élevé.

l Prévenez toute personne sur les lieux du danger relié au bruit.

l’OSHA (reportez-vous aux Principales normes de

OM-254449 Page 6

Page 11

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.

l Ne mettez pas votre tête au-dessus des vapeurs. Ne respirez pas

ces vapeurs.

l 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.

l Si la ventilation est médiocre, utilisez un respirateur anti-vapeurs

approuvé.

l Lire et comprendre les fiches de données de sécurité et les ins-

tructions du fabricant concernant les adhésifs, les revêtements, les nettoyants, les consommables, les produits de refroidissement, les dégraisseurs, les flux et les métaux.

l 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. Assurezvous que l’air ambiant est sain pour la santé.

l 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.

l 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.

l 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.

l N’approchez pas le tube du chalumeau. l Ne saisissez pas la pièce à couper près de la ligne de coupage. l L’arc pilote peut causer des brûlures - n’approchez pas le tube du

chalumeau lorsque vous avez appuyé sur le gâchette.

l Porter une protection corporelle en cuir ou des vêtements ignifu-

ges (FRC). La protection du corps comporte des vêtements sans huile, comme des gants de cuir, une chemise solide, des pantalons sans revers, des chaussures hautes et une casquette.

l 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.

l Mettez l’alimentation hors tension et débranchez le cordon d’ali-

mentation avant de démonter le chalumeau ou de changer une pièce du chalumeau.

l 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 en-

dommagée, elle peut exploser. Puisque les bouteilles de gaz font habituellement partie d’un processus de travail des métaux, assurez-vous de les manipuler correctement.

l Protégez les bouteilles de gaz comprimé contre la chaleur exces-

sive, les chocs mécaniques, des dommages physiques, le laitier, la flamme, les étincelles et l’arc.

l Placer les bouteilles debout en les fixant dans un support station-

naire ou dans un porte-bouteilles pour les empêcher de tomber ou de se renverser.

l Les bouteilles ne doivent pas être près de la zone de coupage ni

de tout autre circuit électrique.

l Un contact électrique ne doit jamais se produire entre un chalu-

meau de plasma d’arc et une bouteille.

l Ne coupez jamais sur une bouteille pressurisée - une explosion

en résulterait.

l Utilisez uniquement des bouteilles de gaz comprimé , des déten-

deurs, des boyaux et des raccords conçus pour l’application déterminée. Gardez-les, ainsi que toute autre pièce associée, en bonne condition.

l 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.

l Le couvercle du détendeur doit toujours être en place, sauf

lorsque vous utilisez la bouteille ou qu’elle est reliée pour usage ultérieur.

l Utilisez les équipements corrects, les bonnes procédures et suffi-

samment de personnes pour soulever, déplacer et transporter les bouteilles.

l Lire et suivre les instructions sur les bouteilles de gaz comprimé,

l’équipement connexe et le dépliant P-1 de la CGA (Compressed Gas Association) mentionné dans les principales normes de sécurité.

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: 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.

5-1. Plasma Cutting System Practices

The pilot arc starts immediately when trigger is pressed.

Standoff distance is 1/8 in. (3.2 mm) for

XT60 Torch.

Step 1. Always connect work clamp to a clean, paint-free location on work piece, as close to cutting area as possible.

Step 2. DO NOTstart pilot arc without cutting or gouging as this shortens the service life of the nozzle and electrode.

Step 3. Maintain approximately a 90° angle to the work piece surface for proper cutting results.

Step 4. Sparks should pass through the work piece and out the bottom when cutting.

Step 5. If sparks flare back from surface, this usually is an indication that either travel speed is too fast or amperage is set too low.

Step 6. When doing extended (nonshielded) cutting, maintain approximately 1/

16 in. standoff between electrode and surface.

Step 7. DO NOT put pressure on shield when drag cutting; instead, slide shield along the surface for proper cutting results.

Step 8. Pulling rather than pushing the torch makes cutting easier. Use a proper guide or template for accurate cutting operations.

OM-254449 Page 25

Page 30

5-2. Sequence Of Cutting Operation

254 087-A

2 3

The pilot arc starts immediately when trigger is pressed.

Step 1. Connect work clamp to a clean,

paint-free location on work piece, as close to cutting area as possible.

Step 2. For standard (shielded) cutting, place drag shield on edge of metal. For extended (non-shielded) cutting, use 1/16-1/ 8 in. (1.6-3.2 mm) standoff distance (dragging tip will reduce tip life).

Step 3. Raise trigger lock and press trigger. Pilot arc starts.

Step 4. After cutting arc starts, slowly start moving torch across metal.

Step 5. Adjust torch speed so sparks go thru metal and out bottom of cut.

Step 6. Pause briefly at end of cut before releasing trigger.

Step 7. Postflow continues for approx. 20 seconds after releasing trigger; cutting arc can be instantly restarted during postflow by raising trigger lock and pressing trigger.

5-3. Sequence Of Gouging Operation

The pilot arc starts immediately when trigger is pressed.

Step 1. Connect work clamp to a clean,

paint-free location on workpiece, as close to cutting area as possible.

Step 2. Trigger pilot arc once before starting to gouge.

Step 3. Hold torch at approximately 45° angle to workpiece.

Step 4. 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.

Step 5. 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.

Step 2. Hold torch at approximately 45° to the workpiece. Raise trigger lock and press trigger. Pilot arc starts.

Step 3. Rotate torch to upright position approximately 90° to surface. When arc has pierced through workpiece, start cutting.

Step 4. Maintain approximately 90° torch position to surface, and continue cutting.

Step 5. 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.

6-3. Checking/Replacing Retaining Cup, Tip, And Electrode

Power must be reset whenever the cup

shutdown system is activated. Always turn Off power when changing or checking consumables. Do NOT overtighten torch shield cup. Gently finger tighten cup onto torch.

1 Torch Shield Cup

Turn Power On and loosen shield cup. If shutdown system works properly, Cup light comes on. If not, immediately turn Off power and have Factory Authorized Service Agent check unit.

If system works properly, retighten cup and reset power.

Turn Off power source before checking torch parts.

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 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

1 Shield Cup

Remove shield cup. Check cup for cracks, and replace if necessary.

2 Tip 3 Opening

Remove tip. Check tip, and replace if opening is deformed or 50% oversize. If inside of tip is not clean and bright, clean with steel wool. Be sure to remove any pieces of steel wool afterwards.

4 Electrode

Check electrode. If center has a pit more than a 1/16 in. (2 mm) deep, remove and replace electrode.

1/32 in. (1 mm) to 1/16 in. (2 mm) maximum pit depth depending on acceptable cut quality

5 Swirl Ring

6 Remove swirl ring. Check ring, and re-

place if side holes are plugged.

Make sure swirl ring is clean of any de-

bris and no holes are obstructed.

7 O-Ring

Check O-ring for cracks or worn spots, and replace if necessary.

Carefully reassemble parts in reverse order.
