SECTION 1 SAFETY PRECAUTIONS
1.0 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.
1.1 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 workpiece has been completely cleaned so that there are no substances on the workpiece 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, Batterymarch 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
SECTION 1 SAFETY PRECAUTIONS
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.
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.
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.

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'extinction 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.

CHOC ÉLECTRIQUE -- Le contact avec des pièces électriques ou les pièces de mise à la terre sous tension peut causer des blessures graves ou mor-
telles. NE PAS utiliser un courant de soudage c.a. dans un endroit humide, en espace restreint ou si un danger de chute se pose.
13
SECTION 1 SÉCURITÉ
1. Assurez-vous que le châssis de la source d'alimentation est branché au système de mise à la terre de l'alimentation d'entrée.
2. Branchez la pièce à traiter à une bonne mise de terre électrique.
3. Branchez le câble de masse à la pièce à traiter et assurez une bonne connexion an d'éviter le risque de choc électrique mortel.
4. Utilisez toujours un équipement correctement entretenu. Remplacez les câbles usés ou endom­magés.
5. Veillez à garder votre environnement sec, incluant les vêtements, l'aire de travail, les câbles, le porte­électrode/torche et la source d'alimentation.
6. Assurez-vous que tout votre corps est bien isolé de la pièce à traiter et des pièces de la mise à la terre.
7. Si vous devez eectuer votre travail dans un espace restreint ou humide, ne tenez vous pas directe­ment sur le métal ou sur la terre; tenez-vous sur des planches sèches ou une plate-forme isolée et portez des chaussures à semelles de caoutchouc.
8. Avant de mettre l'équipement sous tension, isolez vos mains avec des gants secs et sans trous.
9. Mettez l'équipement hors tension avant d'enlever vos gants.
10. Consultez ANSI/ASC Standard Z49.1 (listé à la page suivante) pour des recommandations spéciques concernant les procédures de mise à la terre. Ne pas confondre le câble de masse avec le câble de mise à la terre.
CHAMPS ÉLECTRIQUES ET MAGNÉ­TIQUES — comportent un risque de danger. Le courant électrique qui passe dans n'importe quel con-
ducteur 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'eectuez 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.

2.1 Introduction
The Precision Etch-Arc Plasma Marker is a constricted arc low amperage plasma marking system. It marks at speeds between 100 and 600 ipm. The plasma marking process is similar to the plasma cutting process. However, rather than piercing through the plate, the low amperage plasma arc merely cuts the surface of the plate material between .00020" and .0050" deep. Voltage height control maintains a constant torch stando for consistent, high speed, accurate pattern layout. When the Precision Etch-Arc Plasma Marker is used in conjunction with ESAB’s Vi­sion CNC, Dynamic Current Control is used to precisely control width and depth of marks by proportionally ramp­ing current up and down as the machine accelerates and decelerates. This minimizes pitting at the beginning, corners, and end of the mark. Accurate positioning of the layout lines and marks depends on using the automatic marker osets executed by the CNC during Automatic Mode. However, the marker can be used manually for test­ing and setup.
In automatic operation, the part program controls: machine motion• osets torch• turns on automatic height control• res the torch and begins marking.•

All of these steps can be performed by the operator for manual operation.

ma gas. The plasma gas constricts the arc as it exits
through the nozzle orice. The shield gas creates a
secondary shield around the arc and improves torch
cooling. Before operating the system, check gas pres-
sure settings for both compressed gases.
Set the Test/Operate switch to the TEST po-1. sition to energize the solenoid valves for both compressed air and argon. Adjust the air pressure regulator on the rear 2. of the unit while observing the pressure gauge on the front of the unit. Set pressure to 90 PSI while the air is owing. The argon pressure is adjusted at the sepa-3. rate regulator panel mounted to the cutting machine. While the argon is owing, set the pressure to 75 psi.

SECTION 4 OPERATION
4.3 CNC Setup
The Precision Etch-Arc plasma marker may be interfaced to any cutting machine CNC. The following parameters may or may not be supported by your interface. Before plasma marking, check these parameters, or their equiva­lents, at the machine control:
Stando - On the Vision CNC, this parameter adjusts the actual cutting height (or arc voltage) the torch will main­tain after the arc has started.
Initial Height - Sets the distance the torch will be raised after sensing the plate. When VHC is turned on, the torch will lower to the plate, then retract this distance before starting the arc.
Plasma Travel Delay - Sets the length of time the machine will remain motionless after the arc strikes. Set to zero for the plasma marking process.
Marker Remote Current - This parameter sets the marking current in amperes.
These parameters are preset when using SDP* marker les.*The Vision family of CNCs allows the user to store multiple process parameter les. The les, called SDP les (ScheidDatenPaket = Cutting data package), contain all the same information that can be manually adjusted on the process parameter screen. (See your programming manuals for more information)
4.4 Process Data
The Precision Etch-Arc can produce marked lines in a wide range of widths and depths. It can also operate over a wide range of speeds. The operator must balance these two factors based on the requirements for a specic job. The following pages provide process data for dierent amperage settings. Each page shows the setup param­eters for that amperage and a chart with marking speed range. From the charts, the operator should select the speed setting based on the quality of mark that can be accepted.

SECTION 6 TROUBLESHOOTING
No air ow.
Check air inlet supply. Unit requires 320 • CFH at 65 psig. Check air hose connections.• Does air ow when “air test” switch is in • test position? If not, check torch consumables, replace if • necessary. If above items check OK, the problem is • internal. Take unit to an Authorized Repair Station.
Over Temperature.
The fault light will be illuminated for 1/10th of a second every second. This generally indicates that the • air ow has been blocked. Clear blockage and allow the power supply to cool before operating. Thermal switch may be open. It will open if the heat sink temperature reaches 80 degrees C. With the • machine power o, check the continuity between P1-1 and P1-2 of the control board. If the switch is OK, then the ohmmeter should read a direct short. If not, then it should read open. If the switch is malfunctioning, replace it. Clean the surface of the heat sink before installing switch.•
Over current.
The fault light will be continuously illuminated. This indicates the input current to the main transformer • has exceeded preset limits. To check if the output is shorted, measure resistance by putting ohmmeter leads (ensure HI Freq leads • are disconnected) “+” of the meter to torch, “+” output terminal and work, “-“ lead of the meter to the “-“ output terminal. Reading should be about 2K OHMS. Reverse the voltmeter leads, the resistance read­ing should be less than 1.5 OHMS. Resistance reading is dierent than above, check torch, the output bridge and lter board (PCB5).•
Arc does not transfer to plate.
Make sure work clamp has a good connection to material to be marked. • Check consumables. Replace if necessary.•

SECTION 6 TROUBLESHOOTING
Poor marking performance
Check gas regulators. Should be set to 65 to 70 psig.• The air supply should be free of oil/water.• Check condition of consumables.• Check open circuit voltage.• With high frequency leads disconnected, measure open circuit voltage. • It should be 275 VDC between “Work” and “Torch” terminals.
If not then check one of the following:
Check operation of the Thermal Switch. (See Over Temperature)• Check Air Flow Switch for internal short. Should have Fault Light. Light blinking o for 1/10th second • every second indicates low air ow. Put the Gas Test Switch to TEST. Air should ow through torch. If not, then the ow switch may be stuck in the open position. To check if ow switch is open, put voltme­ter leads between P1-12 and P1-1. It should read about 12 VDC. When ow switch closes, voltage drops to zero volts. Clean or replace ow switch. (see instructions in Section 5)
Gas does not shut o.
Check gas solenoids for operation.• Does gas ow when CNC cable is unplugged. If yes, repair torch. If no, send unit to an authorized repair • station for repair. Check voltage to solenoid coils. If present when start contact is disconnected, replace PCB1 (marker • board). If voltage is “0”, replace solenoid valve.
41
SECTION 6 TROUBLESHOOTING
Fault light activates when start contacts are closed.
The fault light is used to monitor conditions necessary for the safe opera­tion of the Precision Etch-Arc. The fault light will glow amber under the following conditions and the unit will stop working:
High/Low Voltage. The fault light will rapidly blink on and o (5 times per • second). This indicates that the input voltage is outside the “+” or “-“ 15% safe operating range. Flow Fault. The fault light will be mostly on but will blink o for 1/10th of • a second every second. This indicates the gas ow is low.
Check gas pressure at the machine regulator. It should be adjusted to 65 psig. If no gas pressure, check 1. the gas at the supply point. Also check for obstructions in the gas hose. Gas ow may be blocked at the torch tip. Check torch consumables. Also check for any obstructions in 2. the torch leads. Note. If above items check OK, the problem is internal will have to be sent to an authorized
repair station.
Put the Gas Check switch to the on position. Gas should ow through the torch. If not, then the ow 3. switch may be stuck due to oil or dirt in the gas. Clean ow switch per instructions in the maintenance section or replace switch. To check if the ow switch is open, put a voltmeter leads between P1-12 and P1-1. It should read 12 VDC. When the switch closes, voltage will drop to “0”. Gas Test Switch may be malfunctioning.4.
Cut Gas Circuit Failure
The plasma gas circuit consists of a pressure switch and a solenoid. The pressure switch is a normally opened, non-adjustable switch. The switch closes when sucient pressure is applied. It comes preset to 15 psi.

SECTION 6 TROUBLESHOOTING
Gas is on but nothing happens when start contacts are closed.
Check the pilot arc fuse located on the rear panel. If open, re-1. place. Check to ensure high frequency is present at the torch. If not, 2. then listen for high frequency at the high frequency genera­tor. It is located on the bottom/right side of the unit. The high frequency gap is set at 0.030 inches. Disconnect HI Frequency leads. Check for 115 supply voltage between P2-12 and P2-13 of the control board. With high frequency leads disconnected, measure open circuit 3. voltage. It should be 275 VDC between “work” and Torch termi­nals. If not present, then any one of the following may not be working properly: Check for operation of the thermal switch. (see Over Tempera-• ture) Check Gas Check switch operation. It might be stuck in the ON • position. Pilot arc will not initiate if the switch is in the ON posi­tion.
Check Gas ow Switch. There may be an internal short. Measure voltage across C1 and C2 capacitors. It •
should be as follows:
approximately 294 VDC with a 208v unit.• approximately 325 VDC with a 230v unit.• approximately 325 VDC with a 460v unit.• approximately 400 VDC with a 575v unit.•
If readings are not correct then one of the following could be malfunctioning.
Check capacitors C1 and C2 for damage.• Check input bridge/SCR Module (IBR). Replace if malfunctioning.• Check Inrush Current Resistor, R10 and SCR1. Both are located on the input bridge heat sink.
