SAFETY PRECAUTIONS
Safety Precautions
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:
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 tted with the correct lter 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 ameproof gauntlet type gloves, heavy
long-sleeve shirt, cuess 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 ameproof apron may also be desirable as protection against radiated heat and sparks.
4. Hot sparks or metal can lodge in rolled up sleeves,
trouser cus, 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-ammable partition or curtains.
6. Use goggles over safety glasses when chipping
slag or grinding. Chipped slag may be hot and can y far. Bystanders should also wear goggles over safety glasses.
Safety - English
FIRES AND EXPLOSIONS -- Heat from ames and arcs can start res. Hot slag or sparks can also cause res and explosions. Therefore:
1. Remove all combustible materials well away from the work area or cover the materials with a pro­tective non-ammable 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 oors or wall openings and cause a hidden smoldering re or res on the oor 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 work piece has been completely cleaned so that there are no substances on the work piece which might produce ammable or toxic vapors. Do not do hot work on closed containers. They may explode.
4. Have re extinguishing equipment handy for instant use, such as a garden hose, water pail, sand bucket, or portable re extinguisher. Be sure you are trained in its use.
5. Do not use equipment beyond its ratings. For example, overloaded welding cable can overheat and create a re 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 re. Use re 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, Battery march Park, Quincy, MA 02269.
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 conned, or if there is danger of falling.
5
SAFETY PRECAUTIONS
1. Be sure the power source frame (chassis) is con­nected to the ground system of the input power.
2. Connect the work piece to a good electrical ground.
3. Connect the work cable to the work piece. 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.
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 work piece 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 and gases, can cause discomfort or harm, particularly in conned spaces. Do not breathe fumes and gases. Shield­ing gases can cause asphyxiation.
Therefore:
9. Turn o the power before removing your gloves.
10. Refer to ANSI/ASC Standard Z49.1 (listed on next page) for specic grounding recommenda­tions. Do not mistake the work lead for a ground cable.
ELECTRIC AND MAGNETIC FIELDS — May be dangerous. Electric cur­rent owing through any conduc­tor causes localized Electric and
Magnetic Fields (EMF). Welding and cutting current creates EMF around welding cables and welding machines. Therefore:
1. Welders having pacemakers should consult their
physician before welding. EMF may interfere with some pacemakers.
2. Exposure to EMF may have other health eects which
are unknown.
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 specic ventilation recommendations.

AVERTISSEMENT : Ces règles de sécurité ont pour but d'assurer votre protection. Ils récapitulent les informations de pré-
caution provenant des références dans la section des Informations de sécurité supplémen­taires. Avant de procéder à l'installation ou d'utiliser l'unité, assurez-vous de lire et de suivre les précau­tions de sécurité ci-dessous, dans les manuels, les ches d'information sur la sécurité du matériel et sur les étiquettes, etc. Tout défaut d'observer ces précautions de sécurité peut entraîner des blessures
graves ou mortelles.
PROTÉGEZ-VOUS -- Les processus de
soudage, de coupage et de gougeage produisent un niveau de bruit élevé et exige l'emploi d'une protection auditive. L'arc, tout comme le soleil, émet des rayons ultraviolets en plus d'autre rayons qui peuvent causer des blessures à la peau et les yeux. Le métal incan­descent peut causer des brûlures. Une formation reliée à l'usage des processus et de l'équipement est essentielle pour prévenir les accidents. Par conséquent:
1. Portez des lunettes protectrices munies d'écrans la-
téraux lorsque vous êtes dans l'aire de travail, même si vous devez porter un casque de soudeur, un écran facial ou des lunettes étanches.
2. Portez un écran facial muni de verres ltrants et de
plaques protectrices appropriées an de protéger vos yeux, votre visage, votre cou et vos oreilles des étincelles et des rayons de l'arc lors d'une opération ou lorsque vous observez une opération. Avertissez les personnes se trouvant à proximité de ne pas re­garder l'arc et de ne pas s'exposer aux rayons de l'arc électrique ou le métal incandescent.
3. Portez des gants ignifugiés à crispin, une chemise
épaisse à manches longues, des pantalons sans rebord et des chaussures montantes an de vous protéger des rayons de l'arc, des étincelles et du métal incandescent, en plus d'un casque de soudeur ou casquette pour protéger vos cheveux. Il est également recommandé de porter un tablier ininammable an de vous protéger des étincelles et de la chaleur par rayonnement.
4. Les étincelles et les projections de métal incandescent
risquent de se loger dans les manches retroussées, les rebords de pantalons ou les poches. Il est recommandé de garder boutonnés le col et les manches et de porter des vêtements sans poches en avant.
5. Protégez toute personne se trouvant à proximité des
étincelles et des rayons de l'arc à l'aide d'un rideau ou d'une cloison ininammable.
6. Portez des lunettes étanches par dessus vos lunettes de
sécurité lors des opérations d'écaillage ou de meulage du laitier. Les écailles de laitier incandescent peuvent être projetées à des distances considérables. Les per­sonnes se trouvant à proximité doivent également porter des lunettes étanches par dessus leur lunettes de sécurité.
INCENDIES ET EXPLOSIONS -- La chaleur provenant des ammes ou de l'arc peut provoquer un incendie. Le laitier incandescent ou les étincelles
peuvent également provoquer un
incendie ou une explosion. Par conséquent :
1. Éloignez susamment tous les matériaux combus­tibles de l'aire de travail et recouvrez les matériaux avec un revêtement protecteur ininammable. Les matériaux combustibles incluent le bois, les vête­ments, la sciure, le gaz et les liquides combustibles, les solvants, les peintures et les revêtements, le papier, etc.
2. Les étincelles et les projections de métal incandescent peuvent tomber dans les ssures dans les planchers ou dans les ouvertures des murs et déclencher un incendie couvant à l'étage inférieur Assurez-vous que ces ouvertures sont bien protégées des étincelles et du métal incandescent.
3. N'exécutez pas de soudure, de coupe ou autre tra­vail à chaud avant d'avoir complètement nettoyé la surface de la pièce à traiter de façon à ce qu'il n'ait aucune substance présente qui pourrait produire des vapeurs inammables ou toxiques. N'exécutez pas de travail à chaud sur des contenants fermés car ces derniers pourraient exploser.
4. Assurez-vous qu'un équipement d'ex tinction d'incendie est disponible et prêt à servir, tel qu'un tuyau d'arrosage, un seau d'eau, un seau de sable ou un extincteur portatif. Assurez-vous d'être bien instruit par rapport à l'usage de cet équipement.
5. Assurez-vous de ne pas excéder la capacité de l'équipement. Par exemple, un câble de soudage sur­chargé peut surchauer et provoquer un incendie.
6. Une fois les opérations terminées, inspectez l'aire de travail pour assurer qu'aucune étincelle ou projection de métal incandescent ne risque de provoquer un incendie ultérieurement. Employez des guetteurs d'incendie au besoin.
7. Pour obtenir des informations supplémentaires, consultez le NFPA Standard 51B, "Fire Prevention in Use of Cutting and Welding Processes", disponible au National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.

CHAMPS ÉLECTRIQUES ET MAGNÉ­TIQUES — comportent un risque de danger. Le courant électrique qui passe dans n'importe quel conduc-
teur produit des champs électriques et magnétiques localisés. Le soudage et le cou­rant de coupage créent des champs électriques et magnétiques autour des câbles de soudage et l'équipement. Par conséquent :
1. Un soudeur ayant un stimulateur cardiaque doit
consulter son médecin avant d'entreprendre une opération de soudage. Les champs électriques et magnétiques peuvent causer des ennuis pour cer­tains stimulateurs cardiaques.
2. L'exposition à des champs électriques et magné-
tiques peut avoir des eets néfastes inconnus pour la santé.
3. Les soudeurs doivent suivre les procédures suivantes pour minimiser l'exposition aux champs électriques et magnétiques :
A. Acheminez l'électrode et les câbles de masse
ensemble. Fixez-les à l'aide d'une bande adhésive lorsque possible.
B. Ne jamais enrouler la torche ou le câble de masse
autour de votre corps.
C. Ne jamais vous placer entre la torche et les câbles
de masse. Acheminez tous les câbles sur le même côté de votre corps.
D. Branchez le câble de masse à la pièce à traiter le
plus près possible de la section à souder.
E. Veillez à garder la source d'alimentation pour le
soudage et les câbles à une distance appropriée de votre corps.
LES VAPEURS ET LES GAZ -- peuvent causer un malaise ou des dommages corporels, plus particulièrement dans les espaces restreints. Ne re­spirez pas les vapeurs et les gaz. Le gaz de protection risque de causer l'asphyxie. Par conséquent :
1. Assurez en permanence une ventilation adéquate dans l'aire de travail en maintenant une ventila­tion naturelle ou à l'aide de moyens mécanique. N'effectuez jamais de travaux de soudage, de coupage ou de gougeage sur des matériaux tels que l'acier galvanisé, l'acier inoxydable, le cuivre, le zinc, le plomb, le berylliym ou le cadmium en l'absence de moyens mécaniques de ventilation ecaces. Ne respirez pas les vapeurs de ces matériaux.
2. N'eectuez jamais de travaux à proximité d'une opération de dégraissage ou de pulvérisation. Lor­sque la chaleur
ou le rayonnement de l'arc entre en contact avec les
vapeurs d'hydrocarbure chloré, ceci peut déclencher la formation de phosgène ou d'autres gaz irritants, tous extrêmement toxiques.
3. Une irritation momentanée des yeux, du nez ou de la gorge au cours d'une opération indique que la ven­tilation n'est pas adéquate. Cessez votre travail an de prendre les mesures nécessaires pour améliorer la ventilation dans l'aire de travail. Ne poursuivez pas l'opération si le malaise persiste.
4. Consultez ANSI/ASC Standard Z49.1 (à la page suivante) pour des recommandations spéciques concernant la ventilation.

1.3 COMPONENT DESCRIPTION
The components that make up an ESP-1000 are designed specically to interface into a system for use in automated plasma cutting applications.
Refer tothe specic equipment manual for detailed information.
Ultra Life 300 Power Source
Designed for high speed plasma cutting, the Ultra Life 300 is basically a silicon controlled rectier (SCR) DC unit with solid state circuitry. The unit can be operated from 50 to 300 amperes output (cutting) current.
Figure 1-3 ESP-400C Power Source
Figure 1-2. Ultra Life 300 Power Source
The solid state circuitry of the Ultra Life 300 produces stable cutting current and eliminates changes in output current as components heat up to operating tempera­ture. Fluctuations in line voltage within +/- 10% of normal and/are extremely low ripple output current is produced, which results in longer consumable life.
Refer to Instruction Manual F-15-141 for specic details for the Ultra Life 300.
ESP-400C Power Source
The ESP-400C Power Source is a solid state DC pwoer source capable of producing up tp 400 amperes.
The design of the solid state circuitry produces stable cutting current and eliminates changes in output current as components heat up to operating temperature and/or uctuations in line voltages within + or - 10% of nominal. If cutting currents above the rating is required, two ESP­400C units can be paralleled.
Refer to the power source manual for installation instruc­tions.
ESP-600C Power Source
The ESP-600C is normally used in mechanized cutting ap­plications for high speed cutting. The ESP-600C is a solid state DC power source capable of producing 100 to 600 amperes of cutting current at 100% duty cycle (no cool down requirements). The extremely low ripple current is produced by a ripple cancellation technique and results in increased life of plasma consumables. "Current slope up" is also featured with the ESP-600C.

Plumbing Box
The ESP Plumbing Box is an interconnecting device between the torch and other system components. It also contains the arc starting high frequency genera­tor. Connection of functions through the plumbing box include; cut gas, start gas, cut water, torch coolant, pilot arc, cutting current and height control.
Figure 1-4. ESP-600C Power Source
For currents beyond the ESP-600C capability 2 units can be connected in a parallel conguration. Refer to Instruction Manual for specic details of the ESP-600C.
Flow Control
The Flow Control is a programmable Logic Control (PLC) based unit. This device provides all the necessary control functions for various uids and signals to and from other components of the system. Control Inputs/Outputs are connected to the power source, cut water pump, plumb­ing box, coolant circulator, air curtain and the cutting machine control.
Figure 1-6. Plumbing Box Assembly
Coolant Circulator
The WC-7C circulator is a radiator type cooler for circulat­ing a coolant uid through the plasma torch providing heat exchanger action for the internal parts of the torch. Though the system refers to water, it is not recommended that water be used. For the protection of internal parts and lines a specially formulated coolant liquid is avail­able that prevents production of corrosion and mineral buildup. Refer to Instruction Manual F-15-138 for detailed information on the WC-7C unit.

The secondary shield/PT-19XLS improves the cut square­ness. The secondary gas metering box measures the ow rate of shield gas (nitrogen or air).
Adaptor: PT-19XLS to Plumbing Box for shield gas con­nection to torch.
PT-15XL Plasma Torch
The PT-15XL is designed for high current plasma cut­ting with water injection. Cutting is accomplished with nitrogen cut gas up to 750 amps, oxygen cut gas up to 360 amps. Use of H-35 mixture for cut gas extends cur­rent capability up to 1000 amps. Each condition requires specic torch components for the type of cut gas and current level.
Figure 1-8. PT-15XL Plasma Torch
The PT-15XL is designed to eliminate double arcing, high frequency leakage, and electrolytic corrosion of parts. The electrode cooling and nozzle concentricity makes arc ignition more reliable, longer life of the nozzle, electrode and other consumable parts. Operating details for specic cutting conditions are presented in later sections of this manual. Refer to Form F-15-031 for detailed information of the PT-15XL torch.
PT-19XLS Plasma Torch
The PT-19XLS Torch is designed with all the quality stan­dards and feature characteristics of the PT-15XL. The dierences are primarily in applications and conditions for which the PT-19XLS is to be used. The PT-19XLS is a mechanized torch designed for high speed, high current cutting using gas shielding instead ofwater injection.

SECTION 1 DESCRIPTION
The PT-19XLS is intended for applications of dry cutting using air (clean & dry) for the cut gas at current levels up to 200 amps. Oxygen (to 360A) or H-35 (to 600A) can be used with the PT-19XLS, however these gases are not recommended for some materials. Use of an air curtain kit permits the PT-19XLS to be used for underwater cut­ting. Further details of the PT-19XLS are contained in Form F-15-430.
Water Pump
The Water Pump is used to supply de-ionized cut water to the PT-15XL torch for water injected cutting.
Air Curtain
Figure 1-11. Bubble Muer Assembly
The Air Curtain assembly provides improved cutting performance of the PT-15XL and PT-19XLS plasma torches when cutting underwater. A source of oil free air at 80 psig is required to the air curtain control box. A curtain (wall) of air is created around the plasma arc area allowing operation in a relatively dry zone, even with the end of the torch submerged 2 - 3 inches.
PT15XL H.D. AIR CURTAIN
Figure 1-10. Air Curtain Assembly
PT-19XLS AIR CURTAIN
PT-19XLS Water Muer
The PT-19XLS water muer works much as the bubble muer described above.
Underwater Cut quality and speed are enhanced when using the air curtain for all PT-19XLS cutting applications and PT-15XL O2/water injection cutting.
Bubble Muer
The Bubble Muer system creates a bubble of air sur­rounded by water that allows the PT-15XL torch to be used underwater with oxygen cut gas and water injection cutting without signicant loss of cut quality.
This device also allows above water cutting with reduced fume, noise and UV radiation from the arc by the ow of water through the bubble muer. A separate water pump recycles ltered water from the water cutting table through the bubble muer.

Flow Control
2.1 General
Proper installation substantially contributes to the satisfactory and trouble-free operation of the ESP-1000 System components. Each step in this section should be studied carefully and followed as closely as possible. Immediately upon receipt of the ESP components, each should be inspected closely for damage which may have occurred in transit. Notify the carrier of any damage or defects immediately. Instruction manuals for each component of the system are included in the pack­age. It is recommended that these manuals be collected and compiled in a common location.
NOTE
If the components are not to be immediately installed, store them in a clean, dry, and well ventilated area.
2.2 System Component Locations
Power Source
WARNING
When lifting the Power Source using the lifting lugs, ensure the lifting means is securely connected to BOTH lifting lugs to prevent damage to the unit or injury to personnel. DO NOT USE ANY LEVER DEVICE WHICH COULD DAMAGE THE UNIT.
The location of the Power Source should be care­fully selected to ensure satisfactory and dependable service. The Power Source components are maintained at the proper operating temperatures by forced air that is drawn through the cabinet by the fan units. For this reason, it is important that the Power Source be located in an indoor-open area where air can circulate freely at the front, bottom, and rear openings of the cabinet. If space is a premium, leave at least two feet of clearance at the rear of the cabinet.
The Flow Control can be placed on the Power Source or mounted onto the cutting machine. It con­nects to the Power Source by a control cable from 6' to 125' long. The Flow Control needs to be accessible for setting various cutting parameters. After setting the cutting conditions, access to the Flow Control is not required during the cutting operation.
Plumbing Box
The Plumbing Box is normally located on the cutting machine in close proximity to the torch station. Since the torch can be equipped with various standard lengths of cable and hose, the exact location is deter­mined by the conguration and station load capacity of the machine.
Access to the Plumbing Box is not required during the standard operating procedures, location near the operator is not required. Two important considerations pertain to the location of the plumbing box:
1. There should be space for the box door to be opened fully .
2. Sucient space should be provided on all sides to permit easy connection of gas/water hoses and electrical cables to the box.
Secondary Gas Metering Box
The gas metering box can be mounted on the cut­ting machine or a convenient wall with the owmeter vertical. The hose supplied is used to connect metering box to torch shield gas using the adaptor supplied with the plumbing box. The gas metering box must be con­nected to a source of dry oil free shop air or N2 capable
The location should be such that a minimum of dirt, dust, or moisture will be drawn into the air stream. It is desirable to locate the unit so that the top and side panels can be removed for cleaning and troubleshoot-

SECTION 2 INSTALLATION
2.3. SYSTEM CONNECTIONS
Power Source
WARNING
Before making any connections to the output bus bars, make sure the power source is de-energized by opening the line (wall) disconnect switch. To be doubly safe, have a qualied person check the output bus bars with a voltmeter to be sure all power is o.
Input Power Connections
The power sources (ESP-600C, ESP-400 or Ultra Life 300) used with the ESP-1000 system are 3-phase units and must be con­nected to a 3-phase power line. Although designed with line voltage compensation, it is suggested that the unit be operated on a separate line to ensure the performance of the power source is not impaired due to an overloaded circuit.
A line (wall) disconnect switch, with fuses or circuit breakers, shall be used at the main power panel. The primary power input must have four insulated power leads (three power leads and one ground wire). The wires may be a heavy rubber covered cable or may run in a solid or exible conduit.
NOTE
The ground wire must be approximately six inches longer than the power leads. This is a safety measure to ensure that in the event the power lines are accidently pulled out the ground wire will remain connected.
Input conductors must be terminated with ring terminals sized for 1/2 inch hardware before being connected.
NOTE: Refer to the specic equipment manual for
detailed installation instructions.
Flow Control Connections
The Flow Control serves as a form of interface between the various process utilities to enable a central location for setup adjustments. Connections are made to receptacles on the rear panel and are grouped into two sections, the bottom row is for gas and water connections while the top row is for electrical connections. The uid connections should be made rst.

4. CUT GAS OUT - This is a "B" size oxygen tting. The hose is connected from this point to the Cut Gas INPUT on the Plumbing Box.
Electrical Hookups (See Table 2-2 for cables)
1. PARALLELED POWER SOURCE - A cable from a second power source connects to this receptacle whenever two power sources are used in paral­lel. It parallels all control connections between the power source and ow control.
2. AIR CURTAIN - This is used to connect the coil of a solenoid valve in the air curtain control (when used) or to control a relay coil in the water muer pump unit.
3. CUT WATER PUMP - Provides connection to a relay coil in the cut water pump unit
4. WATER COOLER - This point is used to connect to the relay coil in the water cooler.
5. PLUMBING BOX - This cable connection goes to the gas solenoid valves, ow switch, interlock switch and provides power to the primary of the high frequency transformer in the plumbing box.
6. CUTTING MACHINE NUMERICAL CONTROL (CNC)
- This connection provides a current reference signal to the plasma power source and provides control signals to and from the ow control cir­cuits, Start Process Command, Arc On, Process Fault, and E-Stop Interlock.
7. 115 VAC AUXILIARY POWER - This optional con­nection allows the Flow Control to be energized without powering up the system. Disconnect after test function is completed.
