Do not use equipment beyond its ratings. For example, overloaded welding cable can overheat and create a fire hazard. 6. After completing operations, inspect the work area to make certain there are no hot sparks or hot metal which could cause a later fire. Use fire watchers when necessary. 7. For additional information, refer to NFPA Standard 51B, "Fire Prevention in Use of Cutting and Welding Processes", available from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269. WARNING: These Safety Precautions are for your protection. They summarize precautionary information from the references listed in Additional Safety Information section. Before performing any installation or operating procedures, be sure to read and follow the safety precautions listed below as well as all other manuals, material safety data sheets, labels, etc. Failure to observe Safety Precautions can result in injury or death. PROTECT YOURSELF AND OTHERS -Some welding, cutting, and gouging processes are noisy and require ear protection. The arc, like the sun, emits ultraviolet (UV) and other radiation and can injure skin and eyes. Hot metal can cause burns. Training in the proper use of the processes and equipment is essential to prevent accidents. Therefore: ELECTRICAL SHOCK -- Contact with live electrical parts and ground can cause severe injury or death. DO NOT use AC welding current in damp areas, if movement is confined, or if there is danger of falling. 1. Always wear safety glasses with side shields in any work area, even if welding helmets, face shields, and goggles are also required. 2. Use a face shield fitted with the correct filter and cover plates to protect your eyes, face, neck, and ears from sparks and rays of the arc when operating or observing operations. Warn bystanders not to watch the arc and not to expose themselves to the rays of the electric-arc or hot metal. 3. Wear flameproof gauntlet type gloves, heavy long-sleeve shirt, cuffless trousers, high-topped shoes, and a welding helmet or cap for hair protection, to protect against arc rays and hot sparks or hot metal. A flameproof apron may also be desirable as protection against radiated heat and sparks. 4. Hot sparks or metal can lodge in rolled up sleeves, trouser cuffs, or pockets. Sleeves and collars should be kept buttoned, and open pockets eliminated from the front of clothing 5. Protect other personnel from arc rays and hot sparks with a suitable non-flammable partition or curtains. 6. Use goggles over safety glasses when chipping slag or grinding. Chipped slag may be hot and can fly far. Bystanders should also wear goggles over safety glasses. 1. Be sure the power source frame (chassis) is connected to 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 fatal shock. 4. Use well-maintained equipment. Replace worn or damaged 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 from work and from ground. 7. Do not stand directly on metal or the earth while working in tight quarters or a damp area; stand on dry boards or an 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 mistake the work lead for a ground cable. ELECTRIC AND MAGNETIC FIELDS — May be dangerous. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding and cutting current creates EMF around welding cables and welding machines. Therefore: FIRES AND EXPLOSIONS -- Heat from flames and arcs can start fires. Hot slag or sparks can also cause fires and explosions. Therefore: 1. Remove all combustible materials well away from the work area or cover the materials with a protective nonflammable covering. Combustible materials include wood, cloth, sawdust, liquid and gas fuels, solvents, paints and coatings, paper, etc. 2. Hot sparks or hot metal can fall through cracks or crevices in floors or wall openings and cause a hidden smoldering fire or fires on the floor below. Make certain that such openings are protected from hot sparks and metal.“ 3. Do not weld, cut or perform other hot work until the workpiece has been completely cleaned so that there are no substances on the workpiece which might produce flammable or toxic vapors. Do not do hot work on closed containers. They may explode. 4. Have fire extinguishing equipment handy for instant use, such as a garden hose, water pail, sand bucket, or portable fire extinguisher. Be sure you are trained in its use. 1. Welders having pacemakers should consult their physician before welding. EMF may interfere with some pacemakers. 2. Exposure to EMF may have other health effects which are unknown. 3. Welders should use the following procedures to minimize exposure 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. 5 SECTION 1 SAFETY PRECAUTIONS EQUIPMENT MAINTENANCE -- Faulty or improperly maintained equipment can cause injury or death. Therefore: FUMES AND GASES -- Fumes and gases, can cause discomfort or harm, particularly in confined spaces. Do not breathe fumes and gases. Shielding gases can cause asphyxiation. Therefore: 1. Always have qualified personnel perform the installation, troubleshooting, and maintenance work. Do not perform any electrical work unless you are qualified to perform such work. 2. Before performing any maintenance work inside a power source, disconnect the power source from the incoming electrical power. 3. Maintain cables, grounding wire, connections, power cord, and power supply in safe working order. Do not operate any equipment in faulty condition. 4. Do not abuse any equipment or accessories. Keep equipment away from heat sources such as furnaces, wet conditions such as water puddles, oil or grease, corrosive atmospheres and inclement weather. 5. Keep all safety devices and cabinet covers in position and in good repair. 6. Use equipment only for its intended purpose. Do not modify it in any manner. 1. Always provide adequate ventilation in the work area by natural or mechanical means. Do not weld, cut, or gouge on materials such as galvanized steel, stainless steel, copper, zinc, lead, beryllium, or cadmium unless positive mechanical ventilation is provided. Do not breathe fumes from these materials. 2. Do not operate near degreasing and spraying operations. The heat or arc rays can react with chlorinated hydrocarbon vapors to form phosgene, a highly toxic gas, and other irritant gases. 3. If you develop momentary eye, nose, or throat irritation while operating, this is an indication that ventilation is not adequate. Stop work and take necessary steps to improve ventilation in the work area. Do not continue to operate if physical discomfort persists. 4. Refer to ANSI/ASC Standard Z49.1 (see listing below) for specific ventilation recommendations. 5.

Veillez à lire et à observer les précautions énoncées ci-dessous avant de monter l’ équipement ou de commercer à l’utiliser. Tout défaut d’observation de ces précautions risque d’entraîner des blessures graves ou mortelles. 1. a. b. c. d. e. f. 2 PROTECTION INDIVIDUELLE-- Les brûlures de la peau et des yeux dues au rayonnement de l’arc électrique ou du métal incandescent, lors du soudage au plasma ou à l’électrode ou lors du gougeage à l’arc, peuvent s’avérer plus graves que celles résultant d’une exposition prolongée au soleil. Aussi convientil d’observer les précautions suivantes: Portez un écran facial adéquat muni des plaques protectrices et des verres filtrants appropriés afin de vous protéger les yeux, le visage, le cou et les oreilles des étincelles et du rayonnement de l’arc électrique lorsque vous effectuez des soudures ou des coupes ou lorsque vous en observez l’exécution. AVERTISSEZ les personnes se trouvant à proximité de façon à ce qu’elles ne regardent pas l’arc et à ce qu’elles ne s’exposent pas à son rayonnement, ni à celui du métal incandescent. Portez des gants ignifugés à crispins, une tunique épaisse à manches longues, des pantalons sans rebord, des chaussures à embout d’acier et un casque de soudage ou une calotte de protection, afin d’éviter d’exposer la peau au rayonnement de l’arc électrique ou du métal incandescent. ll est également souhaitable d’utiliser un tablier ininflammable de façon à se protéger des étincelles et du rayonnement thermique. Les étincelles ou les projections de métal incandescent risquent de se loger dans des manches retroussées, des bords relevés de pantalons ou dans des poches. Aussi convient-il de garder boutonnés le col et les manches et de porter des vêtements sans poches à l’avant. Protégez des étincelles et du rayonnement de l’arc électrique les autres personnes travaillant à proximité à l’aide d’un écran ininflammable adéquat. Ne jamais omettre de porter des lunettes de sécurité lorsque vous vous trouvez dans un secteur où l’on effectue des opérations de soudage ou de coupage à l’arc. Utilisez des lunettes de sécurité à écrans ou verres latéraux pour piquer ou meûler le laitier. Les piquetures incandescentes de laitier peuvent être projetées à des distances considérables. Les personnes se trouvant à proximité doivent également porter des lunettes de protection. Le gougeage à l’arc et le soudage à l’arc au plasma produisent un niveau de bruit extrêmement élevé (de 100 à 114 dB) et exigent par conséquent l’emploi de dispositifs appropriés de protection auditive. PRÉVENTION DES INCENDES-- Les projections de laitier incandescent ou d’étincelles peuvent provoquer de graves incendies au contact de matériaux combustibles solides, liquides ou gazeux. Aussi faut-il PRÉCAUTIONS DE SÉCURITÉ observer les précautions suivantes: a. Éloigner suffisamment tous les matériaux combustibles du secteur où l’on exécute des soudures ou des coupes à l’arc, à moins de les recouvrir complètement d’une bâche non-inflammable. Ce type de matériaux comprend notamment le bois, les vêtements, la sciure, l’essence, le kérosène, les peintures, les solvants, le gaz naturel, l’acétylène, le propane et autres substances combustibles semblables. b. Les étincelles ou les projections de métal incandescent peuvent tomber dans des fissures du plancher ou dans des ouvertures des murs et y déclencher une ignition lente cachée. Veiller à protéger ces ouvertures des étincelles et des projections de métal. c. N’exécutez pas de soudures, de coupes, d’opérations de gougeage ou autres travaux à chaud à la surface de barils, bidons, réservoirs ou autres contenants usagés, avant de les avoir nettoyés de toute trace de substance susceptible de produire des vapeurs inflammables ou toxiques. d. En vue d’assurer la prévention des incendies, il convient de disposer d’un matériel d’extinction prêt à servir immédiatement, tel qu’un tuyau d’arrosage, un seau à eau, un seau de sable ou un extincteur portatif. e. Une fois le travail à l’arc terminé, inspectez le secteur de façon à vous assurer qu’aucune étincelle ou projection de métal incandescent ne risque de provoquer ultérieurement un feu. 3. CHOC ÉLECTRIQUE-- Le gougeage à l’arc et à l’arc au plasma exige l’emploi de tensions à vide relativement importantes; or, celles-ci risquent de causer des dommages corporels graves et même mortels en cas d’utilisation inadéquate. La gravité du choc électrique reçu dépend du chemin suivi par le courant à travers le corps humain et de son intensité. a. Ne laissez jamais de surfaces métalliques sous tension venir au contact direct de la peau ou de vêtements humides. Veillez à porter des gants bien secs. b. Si vous devez effectuer un travail sur une surface métallique ou dans un secteur humide, veillez à assu-rer votre isolation corporelle en portant des gants secs et des chaussures à semelles de caoutchouc et en vous tenant sur une planche ou une plate-forme sèche. c. Mettez toujours à la terre le poste de soudage/coupage en le reliant par un câble à une bonne prise de terre. d. N’utilisez jamais de câbles usés ou endommagés. Ne surchargez jamais le câble. Utilisez toujours un équipement correctement entretenu. e. Mettez l’équipement hors tension lorsqu’il n’est pas en service. une mise à la masse accidentelle peut en effet provoquer une surchauffe de l’équipement et un danger d’incendie. Ne pas enrouler ou passer le câble autour d’une partie quelconque du corps. f. Vérifiez si le câble de masse est bien relié à la pièce en un point aussi proche que possible de la zone de travail. Le branchement des câbles de masse à l’ossature du bâtiment ou en un point éloigné de la zone de travail augmente en effet le risque de passage d’un courant de sortie par des chaînes de 9 SECTION 1 levage, 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 de travail, des câbles, du porte-électrode et du poste de soudage/coupage. Réparez immédiatement toute fuite d’eau. 4. VENTILATION-- La respiration prolongée des fumées résultant des opérations de soudage/coupage, à l’intérieur, d’un local clos, peut provoquer des malaises et des dommages corporels. Aussi convient-il d’observer les précautions suivantes: a. Assurez en permanence une aération adéquate de l’emplacement de travail en maintenant une ventilation naturelle ou à l’aide de moyens mécaniques. N’effectuez jamais de travaux de soudage ou de coupage sur des matériaux de zinc, de plomb, de beryllium ou de cadmium en l’absence de moyens mécaniques de ventilation capables d’empêcher l’inhalation des fumées dégagées par ces matériaux. b. N’effectuez jamais de travaux de soudage ou de coupage à proximité de vapeurs d’hydrocarbure chloré résultant d’opérations voisines de dégraissage ou de pulvérisation. La chaleur dégagée ou le rayonnement de l’arc peut déclencher la formation de phosgène -gaz particulièrement toxique -- et d’autres gaz irritants, à partir des vapeurs de solvant. c. Une irritation momentanée des yeux, du nez ou de la gorge constatée au cours de l’utilisation de l’équipement dénote un défaut de ventilation. Arrêtezvous de travailler afin de prendre les mesures nécessaires à l’amélioration de la ventilation. Ne poursuivez pas l’opération entreprise si le malaise persiste. d. Certaines commandes comportent des canalisations où circule de l’hydrogène. L’armoire de commande est munie d’un ventilateur destiné à empêcher la formation de poches d’hydrogène, lesquelles présentent un danger d’explosion; ce ventilateur ne fonctionne que si l’interrupteur correspondant du panneau avant se trouve placé en position ON (Marche). Veillez à manœuvrer cette commande en vérifiant si le couvercle est bien en place, de façon à assurer l’efficacité de la ventilation ainsi réalisée. Ne jamais débrancher le ventilateur. e. Les fumées produites par l’opération de soudage ou de coupage peuvent s’avérer toxiques. Aussi est-il nécessaire de disposer en permanence d’un dispositif adéquat de ventilation de type aspirant, afin d’éliminer du voisinage de l’opérateur tout dégagement de fumée visible. f. Consultez les recommandations particulières en matière de ventilation indiquées à l’alinéa 6 de la norme Z49.1 de l’AWS. 5. ENTRETIEN DE L’ÉQUIPEMENT-- Un équipement entretenu de façon défectueuse ou inadéquate risque non seulement de réaliser un travail de mauvaise PRÉCAUTIONS DE SÉCURITÉ qualité mais, chose plus grave encore, d’entraîner des dommages corporels graves, voire mortels en déclenchant des incendies ou des chocs électriques. Observez par conséquent les précautions suivantes: a. Efforcez-vous de toujours confier à un personnel qualifié l’installation, le dépannage et l’entretien du poste de soudage et de coupage.

If the power source remains at idle (no welding being done) for a period of 15 minutes, a pimary contactor will disconnect the main power transformer from the primary AC line. The power source control circuits continued to be powered by a control transformer. The power source will immediately reconnect the primary to the main transformer and start welding when the gun trigger is pulled. 11 SECTION 2 DESCRIPTION 12 SECTION 3 INSTALLATION 3.0 Installation HAZARDOUS VOLTAGES.

Figure 3-30 Installationof the AristoPower 460 "Sleep" Option is now complete. 24 SECTION 4 OPERATION 4.0 Operation Use the wall disconnect switch box to remove ALL power from the welding system. When the power is applied to the AristoPower 460 from the wall disconnect box, power is applied to the input side of the primary contactor only. Turning the AristoPower 460 front panel "power switch" to the "On" position powers the control circuitry and starts the system "boot" process. 4.1 Sequence of Operation With power applied from the wall disconnect switch and the AristoPower 460 power switch in the "On" position: 1 The power lamp will illuminate and the Aristo system will start its boot up sequence which takes about 20 seconds. 2 The power source fan will then start and the primary contactor will engage. The system is now ready to weld. 3 The fan will stop after about 40 seconds unless welding begins. The fan remains on duing welding and stays on for 6 minutes after welding has stopped. 4 After a non-welding period of 15 minutes the primary contactor will disengage ("Sleep") but control circuitry remains active until the gun trigger signals the primary contactor to re-engage and allow welding to continue. The 15 minute timer is reset after welding stops and the sequence is repeated. Note The AristoPower 460 115 vac receptacle maintains 115-120 vac 10 amps during the 15 minute "On" sequence but is disconnected if welding is not completed. 25 SECTION 4 OPERATION 26 SECTION 6 REPLACEMENT PARTS AristoPower 460 "Sleep" Option Kit Bill-of-Material PN-0558004579 Part Number 0558004684 0558038271 (8)950840 0558004686 0558004687 0558004685 0558004689 Description Quantity 1 1 1 1 1 1 1 63300916 64307004 Control Transformer P.
