WARNING: These Safety Precautions are foryour protection. They summarize precaution-ary information from the references listed inAdditional Safety Information section. Before

performing any installation or operating procedures, besure to read and follow the safety precautions listed belowas well as all other manuals, material safety data sheets,labels, etc. Failure to observe Safety Precautions can resultin injury or death.

PROTECT YOURSELF AND OTHERS --Some welding, cutting, and gougingprocesses are noisy and require earprotection. The arc, like the sun, emitsultraviolet (UV) and other radiation and

can injure skin and eyes. Hot metal can cause burns.Training in the proper use of the processes and equip-ment is essential to prevent accidents. Therefore:

1. Always wear safety glasses with side shields in any workarea, even if welding helmets, face shields, and gogglesare also required.

2. Use a face shield fitted with the correct filter and coverplates to protect your eyes, face, neck, and ears fromsparks and rays of the arc when operating or observingoperations. Warn bystanders not to watch the arc andnot to expose themselves to the rays of the electric-arcor hot metal.

3. Wear flameproof gauntlet type gloves, heavy long-sleeveshirt, cuffless trousers, high-topped shoes, and a weld-ing helmet or cap for hair protection, to protect againstarc rays and hot sparks or hot metal. A flameproof apronmay also be desirable as protection against radiatedheat and sparks.

4. Hot sparks or metal can lodge in rolled up sleeves,trouser cuffs, or pockets. Sleeves and collars should bekept buttoned, and open pockets eliminated from thefront of clothing

5. Protect other personnel from arc rays and hot sparkswith a suitable non-flammable partition or curtains.

6. Use goggles over safety glasses when chipping slag orgrinding. Chipped slag may be hot and can fly far.Bystanders should also wear goggles over safety glasses.

FIRES AND EXPLOSIONS -- Heat fromflames and arcs can start fires. Hot slagor sparks can also cause fires and ex-plosions. Therefore:

1. Remove all combustible materials well away from thework area or cover the materials with a protective non-flammable covering. Combustible materials include wood,cloth, sawdust, liquid and gas fuels, solvents, paints andcoatings, paper, etc.

2. Hot sparks or hot metal can fall through cracks orcrevices in floors or wall openings and cause a hiddensmoldering fire or fires on the floor below. Make certainthat such openings are protected from hot sparks andmetal.“

3. Do not weld, cut or perform other hot work until theworkpiece has been completely cleaned so that thereare no substances on the workpiece which might pro-duce flammable or toxic vapors. Do not do hot work onclosed containers. They may explode.

4. Have fire extinguishing equipment handy for instant use,such as a garden hose, water pail, sand bucket, orportable fire extinguisher. Be sure you are trained in itsuse.

SAFETY PRECAUTIONS

11/95

5. Do not use equipment beyond its ratings. For example,overloaded welding cable can overheat and create a firehazard.

6. After completing operations, inspect the work area tomake certain there are no hot sparks or hot metal whichcould cause a later fire. Use fire watchers when neces-sary.

7. For additional information, refer to NFPA Standard 51B,"Fire Prevention in Use of Cutting and Welding Pro-cesses", available from the National Fire Protection Asso-ciation, Batterymarch Park, Quincy, MA 02269.

ELECTRICAL SHOCK -- Contact with liveelectrical parts and ground can causesevere injury or death. DO NOT use ACwelding current in damp areas, if move-ment is confined, or if there is danger offalling.

1. Be sure the power source frame (chassis) is connectedto the ground system of the input power.

2. Connect the workpiece to a good electrical ground.3. Connect the work cable to the workpiece. A poor or

missing connection can expose you or others to a fatalshock.

4. Use well-maintained equipment. Replace worn or dam-aged cables.

5. Keep everything dry, including clothing, work area, cables,torch/electrode holder, and power source.

6. Make sure that all parts of your body are insulated fromwork and from ground.

7. Do not stand directly on metal or the earth while workingin tight quarters or a damp area; stand on dry boards oran insulating platform and wear rubber-soled shoes.

8. Put on dry, hole-free gloves before turning on the power.9. Turn off the power before removing your gloves.

10. Refer to ANSI/ASC Standard Z49.1 (listed on next page)for specific grounding recommendations. Do not mistakethe work lead for a ground cable.

ELECTRIC AND MAGNETIC FIELDS —May be dangerous. Electric current flow-ing through any conductor causes lo-calized Electric and Magnetic Fields(EMF). Welding and cutting current cre-ates EMF around welding cables andwelding machines. Therefore:

1. Welders having pacemakers should consult their physi-cian before welding. EMF may interfere with some pace-makers.

2. Exposure to EMF may have other health effects which areunknown.

3. Welders should use the following procedures to minimizeexposure to EMF:A. Route the electrode and work cables together. Secure

them with tape when possible.B. Never coil the torch or work cable around your body.C. Do not place your body between the torch and work

cables. Route cables on the same side of your body.D. Connect the work cable to the workpiece as close as

possible to the area being welded.E. Keep welding power source and cables as far away

from your body as possible.

�

FUMES AND GASES -- Fumes andgases, can cause discomfort or harm,particularly in confined spaces. Donot breathe fumes and gases. Shield-ing gases can cause asphyxiation.Therefore:

1. Always provide adequate ventilation in the work area bynatural or mechanical means. Do not weld, cut, or gougeon materials such as galvanized steel, stainless steel,copper, zinc, lead, beryllium, or cadmium unless positivemechanical ventilation is provided. Do not breathe fumesfrom these materials.

2. Do not operate near degreasing and spraying opera-tions. The heat or arc rays can react with chlorinatedhydrocarbon vapors to form phosgene, a highly toxicgas, and other irritant gases.

3. If you develop momentary eye, nose, or throat irritationwhile operating, this is an indication that ventilation is notadequate. Stop work and take necessary steps to im-prove ventilation in the work area. Do not continue tooperate if physical discomfort persists.

4. Refer to ANSI/ASC Standard Z49.1 (see listing below)for specific ventilation recommendations.

CYLINDER HANDLING -- Cylinders, ifmishandled, can rupture and violentlyrelease gas. Sudden rupture of cylin-der, valve, or relief device can injure orkill. Therefore:

1. Use the proper gas for the process and use the properpressure reducing regulator designed to operate fromthe compressed gas cylinder. Do not use adaptors.Maintain hoses and fittings in good condition. Followmanufacturer's operating instructions for mounting regu-lator to a compressed gas cylinder.

2. Always secure cylinders in an upright position by chainor strap to suitable hand trucks, undercarriages, benches,walls, post, or racks. Never secure cylinders to worktables or fixtures where they may become part of anelectrical circuit.

3. When not in use, keep cylinder valves closed. Havevalve protection cap in place if regulator is not con-nected. Secure and move cylinders by using suitablehand trucks. Avoid rough handling of cylinders.

4. Locate cylinders away from heat, sparks, and flames.Never strike an arc on a cylinder.

5. For additional information, refer to CGA Standard P-1,"Precautions for Safe Handling of Compressed Gases inCylinders", which is available from Compressed GasAssociation, 1235 Jefferson Davis Highway, Arlington,VA 22202.

EQUIPMENT MAINTENANCE -- Faulty or im-properly maintained equipment can causeinjury or death. Therefore:

1. Always have qualified personnel perform the installa-tion, troubleshooting, and maintenance work. Do not

perform any electrical work unless you are qualified toperform such work.

2. Before performing any maintenance work inside a powersource, disconnect the power source from the incomingelectrical power.

3. Maintain cables, grounding wire, connections, power cord,and power supply in safe working order. Do not operateany equipment in faulty condition.

4. Do not abuse any equipment or accessories. Keepequipment away from heat sources such as furnaces, wetconditions such as water puddles, oil or grease, corrosiveatmospheres and inclement weather.

5. Keep all safety devices and cabinet covers in position andin good repair.

6. Use equipment only for its intended purpose. Do notmodify it in any manner.

a. Éloigner suffisamment tous les matériaux combus-tibles du secteur où l’on exécute des soudures ou descoupes à l’arc, à moins de les recouvrir complètementd’une bâche non-inflammable. Ce type de matériauxcomprend notamment le bois, les vêtements, la sciure,l’essence, le kérosène, les peintures, les solvants, legaz naturel, l’acétylène, le propane et autres sub-stances combustibles semblables.

b. Les étincelles ou les projections de métal incandes-cent peuvent tomber dans des fissures du plancher oudans des ouvertures des murs et y déclencher uneignition lente cachée. Veiller à protéger ces ouverturesdes étincelles et des projections de métal.

c. N’exécutez pas de soudures, de coupes, d’opérationsde gougeage ou autres travaux à chaud à la surfacede barils, bidons, réservoirs ou autres contenantsusagés, avant de les avoir nettoyés de toute trace desubstance susceptible de produire des vapeursinflammables ou toxiques.

d. En vue d’assurer la prévention des incendies, ilconvient de disposer d’un matériel d’extinction prêt àservir immédiatement, tel qu’un tuyau d’arrosage, unseau à eau, un seau de sable ou un extincteur portatif.

e. Une fois le travail à l’arc terminé, inspectez le secteurde façon à vous assurer qu’aucune étincelle ou projec-tion de métal incandescent ne risque de provoquerultérieurement un feu.

3. CHOC ÉLECTRIQUE-- Le gougeage à l’arc et à l’arcau plasma exige l’emploi de tensions à viderelativement importantes; or, celles-ci risquent decauser des dommages corporels graves et mêmemortels en cas d’utilisation inadéquate. La gravité duchoc électrique reçu dépend du chemin suivi par lecourant à travers le corps humain et de son intensité.

a. Ne laissez jamais de surfaces métalliques sous ten-sion venir au contact direct de la peau ou devêtements humides. Veillez à porter des gants biensecs.

b. Si vous devez effectuer un travail sur une surfacemétallique ou dans un secteur humide, veillez à assu-rer votre isolation corporelle en portant des gants secset des chaussures à semelles de caoutchouc et envous tenant sur une planche ou une plate-formesèche.

c. Mettez toujours à la terre le poste de soudage/coupageen le reliant par un câble à une bonne prise de terre.

d. N’utilisez jamais de câbles usés ou endommagés. Nesurchargez jamais le câble. Utilisez toujours unéquipement correctement entretenu.

e. Mettez l’équipement hors tension lorsqu’il n’est pas enservice. une mise à la masse accidentelle peut eneffet provoquer une surchauffe de l’équipement et undanger d’incendie. Ne pas enrouler ou passer le câbleautour d’une partie quelconque du corps.

f. Vérifiez si le câble de masse est bien relié à la pièce enun point aussi proche que possible de la zone detravail. Le branchement des câbles de masse àl’ossature du bâtiment ou en un point éloigné de lazone de travail augmente en effet le risque de pas-sage d’un courant de sortie par des chaînes delevage

�� AVERTISSEMENT: Ces règles de sécurité ont pour objetd’ assurer votre protection. Veillez à lire et à observer lesprécautions énoncées ci-dessous avant de monter l’équipement ou de commercer à l’utiliser. Tout défautd’observation de ces précautions risque d’entraîner desblessures graves ou mortelles.1. PROTECTION INDIVIDUELLE-- Les brûlures de la

peau et des yeux dues au rayonnement de l’arcélectrique ou du métal incandescent, lors du soudageau plasma ou à l’électrode ou lors du gougeage àl’arc, peuvent s’avérer plus graves que cellesrésultant d’une exposition prolongée au soleil. Aussiconvient-il d’observer les précautions suivantes:

a. Portez un écran facial adéquat muni des plaquesprotectrices et des verres filtrants appropriés afin devous protéger les yeux, le visage, le cou et les oreillesdes étincelles et du rayonnement de l’arc électriquelorsque vous effectuez des soudures ou des coupesou lorsque vous en observez l’exécution.

AVERTISSEZ les personnes se trouvant à proximitéde façon à ce qu’elles ne regardent pas l’arc et à cequ’elles ne s’exposent pas à son rayonnement, ni àcelui du métal incandescent.

b. Portez des gants ignifugés à crispins, une tuniqueépaisse à manches longues, des pantalons sansrebord, des chaussures à embout d’acier et uncasque de soudage ou une calotte de protection, afind’éviter d’exposer la peau au rayonnement de l’arcélectrique ou du métal incandescent. ll est égalementsouhaitable d’utiliser un tablier ininflammable defaçon à se protéger des étincelles et du rayonnementthermique.

c. Les étincelles ou les projections de métal incandes-cent risquent de se loger dans des manchesretroussées, des bords relevés de pantalons ou dansdes poches. Aussi convient-il de garder boutonnés lecol et les manches et de porter des vêtements sanspoches à l’avant.

d. Protégez des étincelles et du rayonnement de l’arcélectrique les autres personnes travaillant à proximitéà l’aide d’un écran ininflammable adéquat.

e. Ne jamais omettre de porter des lunettes de sécuritélorsque vous vous trouvez dans un secteur où l’oneffectue des opérations de soudage ou de coupage àl’arc. Utilisez des lunettes de sécurité à écrans ouverres latéraux pour piquer ou meûler le laitier. Lespiquetures incandescentes de laitier peuvent êtreprojetées à des distances considérables. Lespersonnes se trouvant à proximité doivent égalementporter des lunettes de protection.

f. Le gougeage à l’arc et le soudage à l’arc au plasmaproduisent un niveau de bruit extrêmement élevé (de100 à 114 dB) et exigent par conséquent l’emploi dedispositifs appropriés de protection auditive.

2. PRÉVENTION DES INCENDES-- Les projections delaitier incandescent ou d’étincelles peuventprovoquer de graves incendies au contact dematériaux combustibles solides, liquides ou gazeux.Aussi faut-il observer les précautions suivantes:

9/97

�

des câbles de grue ou divers chemins électriques.g. Empêchez l’apparition de toute humidité, notamment

sur vos vêtements, à la surface de l’emplacement detravail, des câbles, du porte-électrode et du poste desoudage/coupage. Réparez immédiatement toutefuite d’eau.

4. VENTILATION-- La respiration prolongée des fuméesrésultant des opérations de soudage/coupage, àl’intérieur, d’un local clos, peut provoquer des mal-aises et des dommages corporels. Aussi convient-ild’observer les précautions suivantes:

a. Assurez en permanence une aération adéquate del’emplacement de travail en maintenant une ventila-tion naturelle ou à l’aide de moyens mécaniques.N’effectuez jamais de travaux de soudage ou decoupage sur des matériaux de zinc, de plomb, deberyllium ou de cadmium en l’absence de moyensmécaniques de ventilation capables d’empêcherl’inhalation des fumées dégagées par ces matériaux.

b. N’effectuez jamais de travaux de soudage ou decoupage à proximité de vapeurs d’hydrocarburechloré résultant d’opérations voisines de dégraissageou de pulvérisation. La chaleur dégagée ou lerayonnement de l’arc peut déclencher la formation dephosgène -- gaz particulièrement toxique -- et d’autresgaz irritants, à partir des vapeurs de solvant.

c. Une irritation momentanée des yeux, du nez ou de lagorge constatée au cours de l’utilisation del’équipement dénote un défaut de ventilation. Arrêtez-vous de travailler afin de prendre les mesures néces-saires à l’amélioration de la ventilation. Ne poursuivezpas l’opération entreprise si le malaise persiste.

d. Certaines commandes comportent des canalisationsoù circule de l’hydrogène. L’armoire de commande estmunie d’un ventilateur destiné à empêcher la forma-tion de poches d’hydrogène, lesquelles présentent undanger d’explosion; ce ventilateur ne fonctionne quesi l’interrupteur correspondant du panneau avant setrouve placé en position ON (Marche). Veillez àmanœuvrer cette commande en vérifiant si lecouvercle est bien en place, de façon à assurerl’efficacité de la ventilation ainsi réalisée. Ne jamaisdébrancher le ventilateur.

e. Les fumées produites par l’opération de soudage oude coupage peuvent s’avérer toxiques. Aussi est-ilnécessaire de disposer en permanence d’un dispositifadéquat de ventilation de type aspirant, afin d’élimi-ner du voisinage de l’opérateur tout dégagement defumée visible.

f. Consultez les recommandations particulières enmatière de ventilation indiquées à l’alinéa 6 de lanorme Z49.1 de l’AWS.

5. ENTRETIEN DE L’ÉQUIPEMENT-- Un équipemententretenu de façon défectueuse ou inadéquate risquenon seulement de réaliser un travail de mauvaisequalité mais, chose plus grave encore, d’entraîner

des dommages corporels graves, voire mortels endéclenchant des incendies ou des chocs électriques.Observez par conséquent les précautions suivantes:

a. Efforcez-vous de toujours confier à un personnel qua-lifié l’installation, le dépannage et l’entretien du postede soudage et de coupage. N’effectuez aucuneréparation électrique sur l’équipement à moins d’êtrequa-lifié à cet effet.

b. Ne procédez jamais à une tâche d’entretienquelconque à l’intérieur du poste de soudage/coupage, avant d’avoir débranché l’alimentationélectrique.

c. Maintenez en bon état de fonctionnement les câbles,le câble de masse, les branchements, le cordond’alimentation et le poste de soudage/coupage.N’utilisez jamais le poste ou l’équipement s’il présenteune défectuosité quelconque.

d. Prenez soin du poste de soudage et de coupage etdes équipements accessoires. Gardez-les à l’écartdes sources de charleur, notamment des fours, del’humidité, des flaques d’eau maintenez-les à l’abri destraces d’huile ou de graisse, des atmosphères corro-sives et des intempéries.

e. Laissez en place tous les dispositifs de sécurité et tousles panneaux de l’armoire de commande en veillant àles garder en bon état.

f. Utilisez le poste de soudage/coupage conformément àson usage prévu et n’effectuez aucune modification.

4.1 GENERAL

If this power source does not operate properly,stop work immediately and investigate the causeof the malfunction. Maintenance work must beperformed by an experienced person, and electri-cal work by a trained electrician. Do not permituntrained persons to inspect, clean, or repair thispower source. Use only recommended replace-ment parts.

Be sure that the branch circuit or main discon-nect switch is off, or electrical input fuses areremoved, before attempting any inspection orwork inside the power source. Placing the powerswitch in the off position does not remove allpower from inside the power source.

4.2 CLEANING

Periodically, remove the cover from the power sourceand blow accumulated dust and dirt from the airpassages and interior components by using cleanlow pressure air. The frequency of cleaning requireddepends upon the environment in which the powersource is used.

It is imperative that all air passages be kept as cleanas possible in order to allow adequate air flow toprovide proper cooling.

After cleaning with low pressure air, check for andtighten any loose hardware, including all electricalconnections. Check for frayed and/or cracked insu-lation on all power cables and replace if necessary.

Failure to replace worn or damaged cables mayresult in a bare cable touching a grounded object.The resulting electrical arc may injure unpro-tected eyes and will present a serious fire hazard.Body contact with a bare cable, connector, orconductor may result in severe electrical shock,causing serious burns or death.

4.3 INSPECTION AND SERVICE

Keep the power source dry, free of oil and grease,and protected at all times from damage by hot metaland sparks.

4.3.1 Fan MotorKeep the fan motor free of accumulated dust and lint.

4.3.2 TransformerOther than periodically cleaning the dust and dirt fromthe transformer, no maintenance is required. Ensurethat only clean, dry, low pressure air is used.

4.3.3 Wire Feeder and Control CircuitsThese circuits are protected by two 10 amp circuitbreakers mounted in the front panel. If these open,the contactor and wire feeder will not operate.

4.3.4 Over Temperature ProtectionIf the power source reaches an abnormally highinternal temperature, the thermal protection willdeenergize the contactor circuit, shutting down thepower source but leaving the cooling fan on. After thepower source has cooled to a safe level, the thermalprotection will automatically reset. While deenerigized,the contactor and wire feeder cannot be operated.

4.3.5 Digital Voltmeter/Ammeter CalibrationTo verify the accuracy of the digital voltmeter/amme-ter combination, the following procedure can be per-formed periodically:1. Place the Panel/Remote switch in Panel position.2. Disconnect cables from the output terminals and

then connect an accurate DC voltmeter to theoutput terminals.

3. Place the Contactor switch in the On position.4. With the primary input power on, turn the Voltage

control knob until you get 25V on the DC voltme-ter. Compare the reading with the reading on thedigital voltmeter on the front panel.

5. If there is a difference in the voltage readings,open front control panel by removing the twomounting screws from the upper corners, re-move meter board from its four mounting posts,and adjust the trimpot (R13) on the meter boardwith a small screwdriver until the digital meterreading matches the DC voltmeter reading. Whensatisfied, reassemble meter board and front con-trol panel.

Table 5-1. PCB Voltage Tests*

NOTE

All voltage readings are taken with the front accesspanel open and the power switch "ON".

Electrical service and repair should be attemptedonly by a trained electrician.

��

DISCONNECT primary power at wall switch, orcircuit breaker, before attempting inspection orwork inside the power source.

If the power source is operating improperly, thefollowing troubleshooting information may be used tolocate the source of the trouble.

Check the problem against the symptoms in thefollowing troubleshooting guide (Table 5-2.) Theremedy for the problem may be quite simple. If thecause cannot be quickly located, open up the unit andperform a simple visual inspection of all the compo-nents and wiring. Check for proper terminal connec-tions, loose or burned wiring or components, blownfuses, bulged or leaking capacitors, or any other signof damage or discoloration.

�� '��'��

The SCRs used in the power source are deviceswhich allow current to flow in only one direction. TheSCRs are designed to provide long trouble-free op-eration; however, should a failure occur, they mayrequire replacement.
