EMC Introduction
Hypertherm’s CE-marked equipment is built in compliance with standard EN60974-10. The equipment should be in stalled and used in accordance with the information be low to achieve elec tro mag net ic com pat i bil i ty.
The limits required by EN60974-10 may not be adequate to com plete ly eliminate in ter fer ­ence when the affected equip ment is in close proximity or has a high degree of sen si tivity. In such cases it may be nec es sary to use other mea sures to further re duce interference.
This cutting equipment is designed for use only in an in dus tri al environment.
Installation and use
The user is responsible for installing and using the plasma equipment according to the manufacturer’s instructions. If elec tro mag net ic disturbances are de tect ed then it shall be the respon si bil i ty of the user to re solve the situation with the technical as sis tance of the man u fac tur er. In some cases this remedial action may be as sim ple as earthing the cutting circuit, see Earthing of Workpiece. In other cas es it could involve constructing an electromag net ic screen enclosing the pow er source and the work complete with associated input filters. In all cases elec tro mag net ic disturbanc es must be reduced to the point where they are no longer trou ble some.
Assessment of area
Before installing the equipment the user shall make an assessment of po ten tial electro ­magnet ic problems in the sur round ing area. The following shall be taken into account:
a. Other supply cables, control cables,
signalling and telephone ca bles; above, below and adjacent to the cutting equipment.
b. Radio and television transmitters and
receivers. c. Computer and other control equip ment. d. Safety critical equipment, for example
guarding of industrial equipment. e. Health of the people around, for example the
use of pacemakers and hear ing aids. f. Equipment used for calibration or
measurement. g. Immunity of other equipment in the
environment. User shall ensure that other
equipment being used in the environment is
com pat i ble. This may require ad di tion al
protection measures. h. Time of day that cutting or other ac tiv i ties
are to be carried out.
The size of the sur round ing area to be con ­sidered will depend on the structure of the building and other activities that are tak ing place. The surrounding area may ex tend beyond the bound aries of the pre mises.
Methods of reducing emissions
Mains supply
Cutting equipment must be con nect ed to the mains supply according to the man u fac tur er’s recom men da tions. If in ter fer ence occurs, it may be necessary to take addi tional precautions such as fil ter ing of the mains supply. Consideration should be given to shield ing the supply cable of per ma nent ly installed cutting equip ment, in metallic conduit or equiv a lent. Shielding should be elec tri cal ly continuous through out its length. The shielding should be con nect ed to the cutting mains supply so that good electrical contact is maintained between the conduit and the cutting pow er source enclosure.

Maintenance of cutting equipment
The cutting equipment must be rou tine ly maintained according to the man u fac tur er’s recom men da tions. All ac cess and service doors and covers should be closed and properly fastened when the cutting equip ment is in operation. The cutting equipment should not be modified in any way except for those chang es and ad just ments covered in the manufac tur er’s instructions. In par tic u lar, the spark gaps of arc striking and sta bi liz ing devices should be adjusted and maintained according to the manu fac tur er’s recommendations.
Cutting cables
The cutting cables should be kept as short as possible and should be po si tioned close together, running at or close to the floor level.
Equipotential bonding
Bonding of all metallic components in the cutting installation and adjacent to it should be considered. However, metallic com po nents bonded to the workpiece will increase the risk that the op er a tor could receive a shock by touch ing these metallic compo nents and the electrode (nozzle for laser heads) at the same time. The op er a tor should be in su lat ed from all such bonded metallic components.
Earthing of workpiece
Where the workpiece is not bonded to earth for electrical safety, nor connected to earth because of its size and position, for ex am ple, ship’s hull or building steel work, a con nec tion bonding the work piece to earth may reduce emis sions in some, but not all instances. Care should be taken to prevent the earthing of the work piece increasing the risk of injury to users, or damage to other elec tri cal equip ment. Where necessary, the con nec tion of the
workpiece to earth should be made by a direct connection to the work piece, but in some countries where direct connection is not permitted, the bonding should be achieved by suit able capacitances se lect ed according to national regulations.
Note: the cutting circuit may or may not be earthed for safety reasons. Changing the earthing arrangements should only be authorized by a person who is com pe tent to assess whether the chang es will in crease the risk of injury, for example, by al low ing parallel cutting cur rent return paths which may damage the earth cir cuits of other equipment. Further guid ance is given in IEC/ TS 62081 Arc Welding Equip ment Installation and Use.
Screening and shielding
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems of in ter fer ence. Screening of the entire plas ma cutting installation may be con sid ered for special applications.

Attention
Genuine Hypertherm parts are the factory­recommended replacement parts for your Hypertherm system. Any damage caused by the use of other than genuine Hypertherm parts may not be covered by the Hypertherm warranty.
You are responsible for the safe use of the Product. Hypertherm does not and cannot make any guarantee or warranty regarding the safe use of the Product in your environment.
General
Hypertherm, Inc. warrants that its Products shall be free from defects in materials and workman ­ship, if Hypertherm is notified of a defect (i) with respect to the power supply within a period of two (2) years from the date of its delivery to you, with the exception of Powermax brand power supplies, which shall be within a period of three (3) years from the date of delivery to you, and (ii) with respect to the torch and leads within a period of one (1) year from its date of delivery to you, and with respect to torch lifter assemblies within a period of one (1) year from its date of delivery to you, and with respect to laser heads within a period of one (1) year from its date of delivery to you. This warranty shall not apply to any Powermax brand power supplies that have been used with phase converters. In addition, Hypertherm does not warranty systems that have been damaged as a result of poor power quality, whether from phase converters or incoming line power. This warranty shall not apply to any Product which has been incorrectly installed, modified, or otherwise damaged. Hypertherm, at its sole option, shall repair, replace, or adjust, free of charge, any defective Products covered by this warranty which shall be returned with Hypertherm’s prior authorization (which shall not be unreasonably withheld), properly packed, to Hypertherm’s place of business in Hanover, New Hampshire, or to an authorized Hypertherm repair facility, all
costs, insurance and freight pre paid. Hypertherm shall not be liable for any repairs, replacement, or adjustments of Products covered by this war ranty, except those made pursuant to this paragraph or with Hypertherm’s prior written consent. The warranty above is
exclusive and is in lieu of all other warranties, express, implied, statutory, or otherwise with respect to the Products or as to the results which may be obtained therefrom, and all implied war ranties or conditions of quality or of merchantability or fitness for a particular purpose or against infringement. The foregoing shall constitute the sole and exclusive remedy for any breach by Hypertherm of its warranty. Distributors/OEMs may offer different
or additional warranties, but Distributors/OEMs are not authorized to give any additional warranty protection to you or make any representation to you purporting to be binding upon Hypertherm.
Certification test marks
Certified products are identified by one or more certification test marks from accredited testing laboratories. The certification test marks are located on or near the data plate. Each certification test mark means that the product and its safety-critical components conform to the relevant national safety standards as reviewed by that testing laboratory. Hypertherm places a certification test mark on its products only after that product is manufactured with safety-critical components that have been authorized by the accredited testing laboratory.
Once the product has left the Hypertherm factory, the certification test marks are invalidated if any of the following occurs:
• The product is significantly modified in a manner that creates a hazard or non-conformance.
• Safety-critical components are replaced with unauthorized spare parts.
WARRANTY
4-08
iv Hypertherm
• Any unauthorized assembly or accessory that uses or generates a hazardous voltage is added.
• There is any tampering with a safety circuit or other feature that is designed into the product as part of the certification.
CE marking constitutes a manufacturer’s declaration of conformity to applicable European directives and standards. Only those versions of Hypertherm products with a CE Marking located on or near the data plate have been tested for compliance with the European Low Voltage Directive and the European EMC Directive. EMC filters needed to comply with the European EMC Directive are incorporated within versions of the power supply with a CE Marking.
Differences in National Standards
Differences in standards include, but are not limited to:
• Voltages
• Plug and cord ratings
• Language requirements
• Electromagnetic compatibility requirements
These differences in national standards may make it impossible or impractical for all certification test marks to be placed on the same version of a product. For example, the CSA versions of Hypertherm’s products do not comply with European EMC requirements and they do not have a CE marking on the data plate.
Countries that require CE marking or have compulsory EMC regulations must use CE versions of Hypertherm products with the CE marking on the data plate. These include:
• Australia
• New Zealand
• Countries in the European Union
• Russia
It is important that the product and its certification test mark be suitable for the end­use installation site. When Hypertherm products are shipped to one country for export to another country, the product must be configured and certified properly for the end­use site.
Higher-level systems
When a system integrator adds additional equipment; such as cutting tables, motor drives, motion controllers or robots; to a Hypertherm plasma cutting system, the combined system may be considered a higher-level system. A higher-level system with hazardous moving parts may constitute industrial machinery or robotic equipment, in which case the OEM or end-use customer may be subject to additional regulations and standards than those relevant to the plasma cutting system as manufactured by Hypertherm.
It is the responsibility of the end-use customer and the OEM to perform a risk assessment for the higher-level system and to provide protection against hazardous moving parts. Unless the higher-level system is certified when the OEM incorporates Hypertherm products into it, the installation also may be subject to approval by local authorities. Seek advice from legal counsel and local regulatory experts if uncertain about compliance.
External interconnecting cables between component parts of the higher level system must be suitable for contaminants and movement as required by the final end-use installation site. When the external inter ­connecting cables are subject to oil, dust, or water contaminants, hard usage ratings may be required. When external interconnecting cables are subject to continuous movement, constant flexing ratings may be required. It is the responsibility of the end-use customer or the OEM to ensure the cables are suitable for the application. Since there are differences in the

SAFETY
RECOGNIZE SAFETY INFORMATION
The symbols shown in this section are used to
identify potential hazards. When you see a safety symbol in this manual or on your machine, understand the potential for personal injury, and follow the related instructions to avoid the hazard.
FOLLOW SAFETY INSTRUCTIONS
Read carefully all safety messages in this
manual and safety labels on your machine.
• Keep the safety labels on your machine in good
condition. Replace missing or damaged labels immediately.
• Learn how to operate the machine and how to use
the controls properly. Do not let anyone operate it without instruction.
• Keep your machine in proper working condition.
Unauthorized modifications to the machine may affect safety and machine service life.
DANGER WARNING CAUTION
Hypertherm uses American National Standards Institute guidelines for safety signal words and symbols. A signal word DANGER or WARNING is used with a safety symbol. DANGER identifies the most serious hazards.
• DANGER and WARNING safety labels are located on your machine near specific hazards.
• DANGER safety messages precede related instructions in the manual that will result in serious injury or death if not followed correctly.
• WARNING safety messages precede related instructions in this manual that may result in injury or death if not followed correctly.
• CAUTION safety messages precede related instructions in this manual that may result in minor injury or damage to equipment if not followed correctly.
Fire Prevention
• Be sure the area is safe before doing any cutting. Keep a fire extinguisher nearby.
• Remove all flammables within 35 feet (10 m) of the cutting area.
• Quench hot metal or allow it to cool before handling or before letting it touch combustible materials.
• Never cut containers with potentially flammable materials inside – they must be emptied and properly cleaned first.
• Ventilate potentially flammable atmospheres before cutting.
• When cutting with oxygen as the plasma gas, an exhaust ventilation system is required.
Explosion Prevention
• Do not use the plasma system if explosive dust or vapors may be present.
• Do not cut pressurized cylinders, pipes, or any closed container.
• Do not cut containers that have held combustible materials.
CUTTING CAN CAUSE FIRE OR EXPLOSION
WARNING
Explosion Hazard
Argon-Hydrogen and Methane Hydrogen and methane are flammable gases that present an explosion hazard. Keep flames away from cylinders and hoses that contain methane or hydrogen mixtures. Keep flames and sparks away from the torch when using methane or argon-hydrogen plasma.
WARNING
Hydrogen Detonation with
Aluminum Cutting
• When cutting aluminum underwater, or with the
water touching the underside of the aluminum, free hydrogen gas may collect under the workpiece and detonate during plasma cutting operations.
• Install an aeration manifold on the floor of the water
table to eliminate the possibility of hydrogen detonation. Refer to the Appendix section of this manual for aeration manifold details.
Hypertherm 1-3
SAFETY
11/08
Touching live electrical parts can cause a fatal shock or severe burn.
• Operating the plasma system completes an electrical circuit between the torch and the workpiece. The workpiece and anything touching the workpiece are part of the electrical circuit.
• Never touch the torch body, workpiece or the water in a water table when the plasma system is operating.
Electric Shock Prevention All Hypertherm plasma systems use high
voltage in the cutting process (200 to 400 VDC are common). Take the following precautions when operating this system:
• Wear insulated gloves and boots, and keep your body and clothing dry.
• Do not stand, sit or lie on – or touch – any wet surface when using the plasma system.
• Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the work or ground. If you must work in or near a damp area, use extreme caution.
• Provide a disconnect switch close to the power supply with properly sized fuses. This switch allows the operator to turn off the power supply quickly in an emergency situation.
• When using a water table, be sure that it is correctly connected to earth ground.
ELECTRIC SHOCK CAN KILL
• Install and ground this equipment according to the instruction manual and in accordance with national and local codes.
• Inspect the input power cord frequently for damage or cracking of the cover. Replace a damaged power cord immediately. Bare wiring can kill.
• Inspect and replace any worn or damaged torch leads.
• Do not pick up the workpiece, including the waste cutoff, while you cut. Leave the workpiece in place or on the workbench with the work cable attached during the cutting process.
• Before checking, cleaning or changing torch parts, disconnect the main power or unplug the power supply.
• Never bypass or shortcut the safety interlocks.
• Before removing any power supply or system enclosure cover, disconnect electrical input power. Wait 5 minutes after disconnecting the main power to allow capacitors to discharge.
• Never operate the plasma system unless the power supply covers are in place. Exposed power supply connections present a severe electrical hazard.
• When making input connections, attach proper grounding conductor first.
• Each Hypertherm plasma system is designed to be used only with specific Hypertherm torches. Do not substitute other torches which could overheat and present a safety hazard.
Use proper precautions when handling printed circuit boards.
STATIC ELECTRICITY CAN DAMAGE CIRCUIT BOARDS
• Store PC boards in anti-static containers.
• Wear a grounded wrist strap when handling PC boards.

SAFETY
11/08
The plasma arc by itself is the heat source used for cutting. Accordingly, although the plasma arc has not been identified as a source of toxic fumes, the material being cut can be a source of toxic fumes or gases that deplete oxygen.
Fumes produced vary depending on the metal that is cut. Metals that may release toxic fumes include, but are not limited to, stainless steel, carbon steel, zinc (galvanized), and copper.
In some cases, the metal may be coated with a substance that could release toxic fumes. Toxic coatings include, but are not limited to, lead (in some paints), cadmium (in some paints and fillers), and beryllium.
Gases produced by plasma cutting vary based on the material to be cut and the method of cutting, but may include ozone, oxides of nitrogen, hexavalent chromium, hydrogen, and other substances if such are contained in or released by the material being cut.
Caution should be taken to minimize exposure to fumes produced by any industrial process. Depending upon the chemical composition and concentration of the fumes (as well as other factors, such as ventilation), there may be a risk of physical illness, such as birth defects or cancer.
It is the responsibility of the equipment and site owner to test the air quality in the area where the equipment is used and to ensure that the air quality in the workplace meets all local and national standards and regulations.
The air quality level in any relevant workplace depends on site-specific variables such as:
• Table design (wet, dry, underwater).
• Material composition, surface finish, and composition of coatings.
• Volume of material removed.
TOXIC FUMES CAN CAUSE INJURY OR DEATH
• Duration of cutting or gouging.
• Size, air volume, ventilation and filtration of the work area.
• Personal protective equipment.
• Number of welding and cutting systems in operation.
• Other site processes that may produce fumes.
If the workplace must conform to national or local regulations, only monitoring or testing done at the site can determine whether the site is above or below allowable levels.
To reduce the risk of exposure to fumes:
• Remove all coatings and solvents from the metal before cutting.
• Use local exhaust ventilation to remove fumes from the air.
• Do not inhale fumes. Wear an air-supplied respirator when cutting any metal coated with, containing, or suspected to contain toxic elements.
• Assure that those using welding or cutting equipment, as well as air-supplied respiration devices, are qualified and trained in the proper use of such equipment.
• Never cut containers with potentially toxic materials inside. Empty and properly clean the container first.
• Monitor or test the air quality at the site as needed.
• Consult with a local expert to implement a site plan to ensure safe air quality.

Instant-On Torches
Plasma arc comes on immediately when the torch switch is activated.
A PLASMA ARC CAN CAUSE INJURY AND BURNS
The plasma arc will cut quickly through gloves and skin.
• Keep away from the torch tip.
• Do not hold metal near the cutting path.
• Never point the torch toward yourself or others.
Eye Protection Plasma arc rays produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin.
• Use eye protection in accordance with applicable national or local codes.
• Wear eye protection (safety glasses or goggles with side shields, and a welding helmet) with appropriate lens shading to protect your eyes from the arc’s ultraviolet and infrared rays.
Skin Protection Wear protective clothing to protect against burns caused by ultraviolet light, sparks and hot metal.
• Gauntlet gloves, safety shoes and hat.
• Flame-retardant clothing to cover all exposed areas.
• Cuffless trousers to prevent entry of sparks and slag.
• Remove any combustibles, such as a butane lighter or matches, from your pockets before cutting.

DRY DUST COLLECTION INFORMATION
At some sites, dry dust can represent a potential explosion hazard.
The U.S. National Fire Protection Association’s 2007 edition of NFPA standard 68, “Explosion Protection by Deflagration Venting,” provides requirements for the design, location, installation, maintenance, and use of devices and systems to vent combustion gases and pressures after any deflagration event. Consult with the manufacturer or installer of any dry dust collection system for applicable requirements before you install a new dry dust collection system or make significant changes in the process or materials used with an existing dry dust collection system.
Consult your local “Authority Having Jurisdiction” (AHJ) to determine whether any edition of NFPA 68 has been “adopted by reference” in your local building codes.
Refer to NFPA68 for definitions and explanations of regulatory terms such as deflagration, AHJ, adopted by reference, the Kst value, deflagration index, and other terms.
Note 1 – Hypertherm’s interpretation of these new requirements is that unless a site-specific evaluation has been completed to determine that all dust generated is not combustible, the 2007 edition of NFPA 68 requires the use of explosion vents designed to the worst-case Kst value (see annex F) that could be generated from dust so that the explosion vent size and type can be designed. NFPA 68 does not specifically identify plasma cutting or other thermal cutting processes as requiring deflagration venting systems, but it does apply these new requirements to all dry dust collection systems.
Note 2 – Users of Hypertherm manuals should consult and comply with all applicable federal, state, and local laws and regulations. Hypertherm does not, by the publication of any Hypertherm manual, intend to urge action that is not in compliance with all applicable regulations and standards, and this manual may never be construed as doing so.

SÉCURITÉ
L’arc plasma est lui-même la source de chaleur utilisée pour le coupage. Par conséquent, bien que l’arc plasma n’ait pas été reconnu comme une source de vapeurs toxiques, le matériau coupé peut être une source de vapeurs ou de gaz toxiques qui épuisent l’oxygène.
Les vapeurs produites varient selon le métal coupé. Les métaux qui peuvent dégager des vapeurs toxiques comprennent, entre autres, l’acier inoxydable, l’acier au carbone, le zinc (galvanisé) et le cuivre.
Dans certains cas, le métal peut être revêtu d’une substance susceptible de dégager des vapeurs toxiques. Les revêtements toxiques comprennent entre autres, le plomb (dans certaines peintures), le cadmium (dans certaines peintures et enduits) et le béryllium.
Les gaz produits par le coupage plasma varient selon le matériau à couper et la méthode de coupage, mais ils peuvent comprendre l’ozone, les oxydes d’azote, le chrome hexavalent, l’hydrogène et autres substances présentes dans le matériau coupé ou en émanent.
On doit prendre les précautions qui s’imposent pour réduire au minimum l’exposition aux vapeurs produites par tout processus industriel. Selon la composition chimique et la concentration des vapeurs (ainsi que d’autres facteurs comme la ventilation), il peut y avoir un risque de maladie physique, comme des malformations ou le cancer.
Il incombe au propriétaire du matériel et du site de vérifier la qualité de l’air dans le secteur où l’on utilise le matériel et de s’assurer que la qualité de l’air sur les lieux de travail répond aux normes et réglementation locales et nationales.
LES VAPEURS TOXIQUES PEUVENT PROVOQUER DES BLESSURES OU LA MORT
Le niveau de qualité de l’air dans tout lieu de travail dépend des variables propres au site comme :
• Type de table (humide, sèche, sous l’eau).
• Composition du matériau, fini de la surface et composition des revêtements.
• Volume de matériau enlevé.
• Durée du coupage ou du gougeage.
• Dimensions, volume d’air, ventilation et filtration de la zone de travail.
• Équipement de protection individuelle.
• Nombre de systèmes de soudage et de coupage en fonctionnement.
• Autres procédés du site qui peuvent produire des vapeurs.
Si les lieux de travail doivent être conformes aux règlements nationaux ou locaux, seuls les contrôles ou les essais effectués au site peuvent déterminer si celui-ci se situe au-dessus ou au-dessous des niveaux admissibles.
Pour réduire le risque d’exposition aux vapeurs :
• Éliminer tout revêtement et solvant du métal avant le coupage.
• Utiliser la ventilation d’extraction locale pour éliminer les vapeurs de l’air.
• Ne pas inhaler les vapeurs. Porter un respirateur à adduction d’air quand on coupe des métaux revêtus d’éléments toxiques ou qui en contiennent ou sont susceptibles d’en contenir.
• S’assurer que les personnes qui utilisent un matériel de soudage ou de coupage ainsi que les dispositifs de respiration par adduction d’air sont qualifiés et ont reçu la formation sur la bonne utilisation d’un tel matériel.
• Ne jamais couper les contenants dans lesquels il peut y avoir des matériaux toxiques. En premier lieu, vider et nettoyer correctement le contenant.
• Contrôler ou éprouver la qualité de l’air au site selon les besoins.
• Consulter un expert local pour mettre en œuvre un plan du site afin d’assurer une qualité de l’air sûre.
11/08
Torches à allumage instantané
L’arc plasma s’allume immédiatement après que la torche soit mise en marche.
L’ARC PLASMA PEUT PROVOQUER DES BLESSURES OU DES BRÛLURES
L’arc plasma coupe facilement les gants et la peau.
• Rester éloigné de l’extrémité de la torche.
• Ne pas tenir de métal près de la trajectoire de coupe.
• Ne jamais pointer la torche vers soi ou d’autres personnes.
Protection des yeux Les rayons de l’arc plasma produisent de puissants rayons visibles ou invisibles (ultraviolets et infrarouges) qui peuvent brûler les yeux et la peau.
• Utiliser des lunettes de sécurité conformément aux codes locaux ou nationaux en vigueur.
• Porter des lunettes de protection (lunettes ou masque muni d’écrans latéraux et encore masque de soudure) avec des verres teintés appropriés pour protéger les yeux des rayons ultraviolets et infrarouges de l’arc.
Protection de la peau Porter des vêtements de sécurité pour se protéger contre les brûlures que peuvent causer les rayons ultraviolets, les étincelles et le métal brûlant :
• Gants à crispin, chaussures et casque de sécurité.
• Vêtements ignifuges couvrant toutes les parties exposées du corps.
• Pantalon sans revers pour éviter que des étincelles ou des scories puissent s’y loger.
• Avant le coupage, retirer de ses poches tout objet combustible comme les briquets au butane ou les allumettes.
Zone de coupage Préparer la zone de coupage afin de réduire la réverbération et la transmission de la lumière ultraviolette :
• Peindre les murs et autres surfaces de couleur sombre pour réduire la réflexion de la lumière.
• Utiliser des écrans et autres dispositifs de protection afin de protéger les autres personnes de la lumière et de la réverbération.
• Prévenir les autres personnes de ne pas regarder l’arc. Utiliser des affiches ou des panneaux.

SÉCURITÉ
INFORMATION SUR LE DÉPOUSSIÉRAGE
À certains endroits, la poussière peut représenter un risque d’explosion potentiel. À certains endroits, la poussière peut représenter un risque d’explosion potentiel.
La norme NFPA 68 de la National Fire Protection Association des É.-U. (édition 2007) « Explosion Protection by Deflagration Venting » établit les exigences relatives à la conception, à l’emplacement, à l’installation, à l’entretien et à l’utilisation de dispositifs et de systèmes pour évacuer à l’air libre les gaz de combustion et les pressions après une éventuelle déflagration. Communiquer avec le fabricant ou avec l’installateur pour tout système de dépoussiérage afin de connaître les exigences applicables avant d’installer un tel système neuf ou d’apporter des modifications importantes aux procédés ou aux matériaux utilisés à un système de dépoussiérage existant.
Consultez l’autorité compétente locale pour déterminer si une édition de la NFPA 68 a été adoptée par référence dans vos codes du bâtiment locaux.
Voir le document NFPA68 pour obtenir des définitions et des explications des termes réglementaires tels que « déflagration, autorité compétente, adopté par référence, valeur du pire cas, indice de déflagration » et autres termes.
Note 1 – L’interprétation d’Hypertherm de ces nouvelles exigences est que, sauf évaluation particulière du site, pour déterminer que toute la poussière produite n’est pas combustible, l’édition 2007 de la NFPA 68 exige l’utilisation d’évents d’explosion conçus pour la valeur du pire des cas (voir annexe F) qui pourrait provenir de la poussière de sorte que l’on puisse concevoir la dimension et le type d’évent d’explosion. La NFPA 68 ne stipule pas particulièrement le procédé de coupage plasma particulier ou autres procédés de coupage thermique comme le prescrivent ces nouveaux règlements à tous les systèmes de dépoussiérage.
Note 2 – Les utilisateurs des manuels d’Hypertherm doivent consulter tous les règlements et lois fédéraux et locaux applicables et s’y conformer. Hypertherm n’a pas l’intention, en publiant un manuel d’Hypertherm, de demander des mesures qui ne sont pas conformes aux règlements et normes applicables et ce manuel ne peut jamais être interprété dans ce sens.

El arco plasma es por si solo la fuente de calor que se usa para cortar. Según esto, aunque el arco de plasma no ha sido identificado como la fuente de humo tóxico, el material que se corta puede ser la fuente de humo o gases tóxicos que vacían el oxígeno.
El humo producido varía según el metal que está cortándose. Metales que pueden liberar humo tóxico incluyen, pero no están limitados a, acero inoxidable, acero al carbón, cinc (galvanizado), y cobre.
En algunos casos, el metal puede estar recubierto con una sustancia que podría liberar humos tóxicos. Los recubrimientos tóxicos incluyen, pero no están limitados a, plomo (en algunas pinturas), cadmio (en algunas pinturas y rellenos), y berilio.
Los gases producidos por el corte por plasma varían basándose en el material a cortarse y el método de cortar, pero pueden incluir ozono, óxidos de nitrógeno, cromo hexavalente, hidrógeno, y otras substancias, si están contenidas dentro o liberadas por el material que se corta.
Se debe tener cuidado de minimizar la exposición del humo producido por cualquier proceso industrial. Según la composición química y la concentración del humo (al igual que otros factores, tales como ventilación), puede haber el riesgo de enfermedad física, tal como defectos de natividad o cáncer.
Es la responsabilidad del dueño del equipo y instalación el comprobar la calidad de aire en el lugar donde se está usando el equipo para garantizar que la calidad del aire en el lugar de trabajo cumpla con todas las normas y reglamentos locales y nacionales.
HUMOS TÓXICOS PUEDEN CAUSAR LESIONES O MUERTE
El nivel de la calidad del aire en cualquier lugar de trabajo relevante depende en variables específicas al sitio tales como:
• Diseño de mesa (mojada, seca, bajo agua).
• La composición del material, el acabado de la superficie, y la composición de los recubrimientos.
• Volumen que se quita del material.
• La duración del corte o ranura.
• Tamaño, volumen del aire, ventilación y filtración del lugar de trabajo.
• Equipo de protección personal.
• Número de sistemas de soldar y cortar en la operación.
• Otros procesos del lugar que pueden producir humo.
Si el lugar de trabajo debe cumplir reglamentos nacionales o locales, solamente el monitoreo o las pruebas que se hacen en el lugar pueden determinar si el sitio está encima o debajo de los niveles permitidos.
Para reducir el riesgo de exposición a humo:
• Quite todos los recubrimientos y solventes del metal antes de cortar.
• Use ventilación extractora local para quitar humo del aire.
• No inhale el humo. Use un respirador con fuente propia de aire cuando corte cualquier metal recubierto con, o sospechado de contener, elementos tóxicos.
• Garantice que aquéllos usando equipo de soldar o cortar, al igual que aparatos de respiración con aire propio de aire, estén capacitados y entrenados en el uso apropiado de tal equipo.
• Nunca corte recipientes con materiales potencialmente tóxicos adentro. Primero, vacíe y limpie el recipiente adecuadamente.
• Monitoree o compruebe la calidad del aire en el sitio como fuera necesario.
• Consulte con un experto local para realizar un plan al sitio para garantizar la calidad de aire seguro.
11/08
Antorchas de encendido instantáneo
El arco de plasma se enciende inmediatamente después de activarse el interruptor de la antorcha.
EL ARCO DE PLASMA PUEDE CAUSAR LESIONES Y QUEMADURAS
El arco de plasma puede cortar a través de guantes y de la piel con rapidez.
• Manténgase alejado de la punta de la antorcha.
• No sostenga el metal junto al trayecto de corte.
• Nunca apunte la antorcha hacia Ud. mismo o hacia otras personas.
Protección para los ojos Los rayos del arco de plasma producen rayos intensos visibles e invisibles (ultravioleta e infrarrojo) que pueden quemar los ojos y la piel.
• Utilice protección para los ojos de conformidad con los códigos locales o nacionales aplicables.
• Colóquese protectores para los ojos (gafas o anteojos protectores con protectores laterales, y bien un casco de soldar) con lentes con sombreado adecuado para proteger sus ojos de los rayos ultravioleta e infrarrojos del arco.
Protección para la piel Vista ropa de protección para proteger la piel contra quemaduras causadas por la radiación ultravioleta de alta intensidad, por las chispas y por el metal caliente:
Guantes largos, zapatos de seguridad y gorro.
Roipa de combustión retardada y que cubra todas las partes expuestas.
Pantalones sin dobladillos para impedir que recojan chispas y escorias.
Retire todo material combustible de los bolsillos, como encendedores a butano e inclusive cerillas, antes de
comenzar a cortar.
Área de corte Prepare el área de corte para reducir la reflexión y la transmisión de la luz ultravioleta:
Pinte las paredes y demás superficies con colores oscuros para reducir la reflexión.
Utilice pantallas o barreras protectoras para proteger a los demás de los destellos.
Advierta a los demás que no debe mirarse el arco. Utilice carteles o letreros.

INFORMACIÓN SOBRE LA COLECCIÓN DE POLVO SECO
En algunos sitios, el polvo seco puede representar un peligro potencial de explosión.
La edición del 2007 de “U.S. National Fire Protection Association” iniciales en inglés NFPA (La Asociación Americana Nacional de Protección Contra Incendios) del estándar 68 “Protección de Explosión por medio de Respiradero de Deflagración” proporciona requisitos para el diseño, ubicación, instalación, mantenimiento, y uso de aparatos y sistemas para dar salida a gases de combustión y presiones después de todo evento de deflagración. Consulte con el fabricante o instalador de cualquier sistema de colección de polvo seco para los requisitos aplicables antes de que instale un sistema nuevo de colección de polvo seco, o haga cambios significativos en el proceso o materiales que se usen con un sistema existente de colección de polvo seco.
Consulte su “Autoridad que Tenga Jurisdicción” (iniciales en inglés AHJ) local para determinar si cualquier edición de la NFPA 68 ha sido “adoptada por referencia” en los códigos de construcción locales.
Remítase a la NFPA 68 para definiciones y explicaciones de los términos reguladores como “deflagración, AHJ, adoptada por referencia, el valor Kst, índice de deflagración” y otros términos.
Nota 1 – La interpretación de Hypertherm de estos nuevos requisitos es que, a no ser que se haya completado una evaluación específica del sitio para determinar que todo polvo generado no es combustible, la edición del 2007 de la NFPA 68 requiere el uso de respiraderos de explosión diseñados para el peor caso del valor Kst (vea anexo F) que pudiera ser generado por el polvo, de manera que el tamaño y tipo del respiradero de explosión pueda diseñarse. La NFPA 68 no identifica específicamente corte por plasma u otros procesos de cortes termales como si requirieran sistemas de respiraderos de deflagración, pero en realidad aplica estos nuevos requisitos a todos los sistemas de colección de polvos secos.
Nota 2 – Los usuarios de los manuales de Hypertherm deberían consultar y cumplir con todas las leyes y reglamentos federales, estatales y locales aplicables. Hypertherm, al publicar todo manual de Hypertherm, no intenta urgir acción que no esté en cumplimiento con todos los reglamentos y normas, y este manual nunca debe interpretarse como si lo hiciera así.

Gas supply
The gas supply for the Powermax30 can be shop-compressed or cylinder-compressed. A high­pressure regulator must be used on either type of supply and must be capable of delivering gas to the filter on the power supply at 3.5 scfm @ 65 psi (99.1 l/min @ 4.5 bar). To ensure adequate pressure to the power supply, set the regulator to 80 to 100 psi (5.5 to 6.9 bar).
If gas supply quality is poor, cut speeds decrease, cut quality deteriorates, cutting thickness capability decreases, and the life for consumables shortens.
WARNING
Do not allow the gas supply pressure to exceed 135 psi (9.3 bar). The filter bowl may explode if this pressure is exceeded.
Connection
Connect the gas supply to the system using an inert gas hose with a 3/8 inch (9.5 mm) internal diameter and a 1/4 NPT quick-disconnect coupler. The Powermax30 consumables kit includes a 1/4 FPT x 1/8 NPT air fitting reducer as well.
Caution: Synthetic lubricants containing esters that are used in some air
compressors will damage polycarbonates used in the air regulator bowl.

OPERATION
Duty cycle and overheating
The duty cycle is the amount of time, in minutes, that a plasma arc can remain on within a 10-minute period when operating at an ambient temperature of 104° F (40° C). With a 120 V input:
• At 30 A, the arc can remain on for 3.5 minutes out of 10 minutes without causing the unit to overheat (35% duty cycle).
• At 23 A, the arc can remain on for 6 minutes out of 10 (60%).
• At 18 A, the arc can remain on for 10 minutes (100%).
With a 200-240 V input:
• At 30 A, the arc can remain on for 5 minutes out of 10 (50% duty cycle).
• At 24 A, the arc can remain on for 7.5 minutes out of 10 (75%).
• At 21 A, the arc can remain on for 10 minutes (100%).
If the power supply overheats because the duty cycle is exceeded, the temperature LED will illuminate, the arc will shut off, and the cooling fan will continue to run. To resume cutting, wait for the temperature LED to extinguish.
Common cutting faults
The torch does not cut completely through the workpiece. The causes can be:
• The cut speed is too fast.
• The consumables are worn.
• The metal being cut is too thick.
• The work clamp is not attached properly to the workpiece.
The arc sputters and consumables life is shorter than expected. The cause can be:
• Moisture in the gas supply.
