WARNING: These Safety Precautions are
for your protection. They summarize
precautionary information from the
references listed in Additional Safety
Information section. Before per forming 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, e mits
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, cuess 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 ameproo f apron may also
be desirable as protection against radiated heat
and sparks.
4. Hot sparks or metal can lodge in rolled up sleeves,
trouser cus, 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.
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, Batter y 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 conned, or if there is
danger of falling.
13
SAFETY
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 ever ything 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 o the power before removing your gloves.
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 conned spaces. Do
not breathe fumes and gases. Shielding gases can cause asphyxiation.
Therefore:
10. Refer to ANSI/ASC Standard Z49.1 (listed on
next page) for specic 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 eects 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 specic ventilation recommendations.

5. WARNING: This product, when used for welding
or cutting, produces fumes or gases which contain chemicals known to the State of California
to cause birth defects and, in some cases, cancer. (California Health & Safety Code §25249.5
et seq.)
CYLINDER HANDLING -- Cylinders,
if mishandled, can rupture and violently release gas. Sudden rupture
of cylinder, valve, or relief device can
injure or kill. Therefore:
1. Use the proper gas for the process and use the
proper pressure reducing regulator designed to
operate from the compressed gas cylinder. Do not
use adaptors. Maintain hoses and ttings in good
condition. Follow manufacturer's operating instructions for mounting regulator to a compressed gas
cylinder.
2. Always secure cylinders in an upright position by
chain or strap to suitable hand trucks, undercarriages, benches, walls, post, or racks. Never secure
cylinders to work tables or xtures where they may
become part of an electrical circuit.
3. When not in use, keep cylinder valves closed. Have
valve protection cap in place if regulator is not connected. Secure and move cylinders by using suitable
hand trucks. Avoid rough handling of cylinders.
4. Locate cylinders away from heat, sparks, and ames.
Never strike an arc on a cylinder.
5. For additional information, refer to CGA Standard P-1,
"Precautions for Safe Handling of Compressed Gases
in Cylinders", which is available from Compressed
Gas Association, 1235 Jeerson Davis Highway,
Arlington, VA 22202.
EQUIPMENT MAINTENANCE -- Faulty or improperly maintained equipment can cause
injury or death. Therefore:
1. Always have qualied personnel perform the instal-
lation, troubleshooting, and maintenance work.
Do not perform any electrical work unless you are
qualied 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.

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 latéraux
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 an 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 an 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
ininammable an 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 ininammable.
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 susamment tous les matériaux combustibles
de l'aire de travail et recouvrez les matériaux avec un
revêtement protecteur ininammable. Les matériaux
combustibles incluent le bois, les vêtements, la sciure, le
gaz et les liquides combustibles, les solvants, les p eintures
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 inammables
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'extinc tion 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 surchauer 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.

CHAMPS ÉLECTRIQUES ET MAGNÉTIQUES — com-
portent un risque de danger. Le
courant électrique qui passe dans
n'importe quel conducteur produit
des champs électriques et magné-
tiques 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 eets 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'eectuez 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 ecaces. Ne
respirez pas les vapeurs de ces matériaux.
2. N'eectuez 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 an
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 spéciques
concernant la ventilation.

System Diagrams
The following pages illustrate dierent system congurations available on the m3 Generation 2 (m3 G2). With
this system, ESAB oers 8 dierent congurations to meet customer’s requirements. Below are the descriptions
of each conguration.
1. Base System
This system is the basic conguration for the m3 G2 Plasma System. It contains the major components, such as
the Power Supply (EPP-202/362/540/720), PT-36 Torch, Remote Arc Starter (RAS), Plasma Gas Control (PGC), Shield
Gas Control (SGC), and Interface Control Hub (ICH). This system will meet most customers’ needs in cutting carbon
steel, stainless steel, and aluminum. It also has the functionality of marking on carbon steel and stainless steel with
the same torch and the same consumables. By simply alternating cutting and marking mode on-the-y, this system
is capable of cutting and marking in the same part program without changing the consumables.
To use this system, customer CNC needs to send start signal and corner signal while in geometric corner; at the
same time, customer CNC needs to monitor the fault signal and motion enable signal from ICH. This base system
does not come with Automatic Height Control (AHC). Customer will have to provide AHC and control its sequence.
2. Base System + AHC
This system includes the Base System plus the ESAB AHC, called a “B4 lifter”. In this conguration, ICH will control
plasma sequence, and also the AHC sequence. Customer CNC needs to provide the start signal and corner signal
for normal cutting.
3. Base System + A/C
This system includes the above Base System and ESAB Air Curtain (A/C). Air Curtain is a device used to improve the
performance of plasma arc when cutting underwater. ICH from the Base System will control the sequence and turn
on/o the air.
4. Base System + WIC
This system is congured to introduce the Water Injection Control (WIC), a module used to regulate cut water ow
to shield the cutting process. This conguration is to meet needs of a customer who wants to cut stainless steel
without using H35. This system still uses the standard PT-36 torch, but a dierent set of consumables. Similar to the
dry system, this WIC system can also do marking with water shield.
5. Base System + AHC + WIC
This system provides customer the Base System, AHC (Automatic Height Control), and WIC (Water Injection
Control). With this system, customer needs only to provide start signal and corner signal for cutting stainless steel
with water injection.
6. Base System + AHC + A/C
This system gives the customer the ability to cut under water with ESAB Automatic Height Control (AHC).
7. Base System + WIC + A/C
This system is the Base System adding Water Injection Control (WIC) and Air Curtain (A/C). Customer needs to
provide their own Height Control and control its sequence.
8. Base System + AHC + WIC + A/C
This complete system gives the opportunity for customer to cut carbon steel, stainless steel, and aluminum with
ESAB Auto Height Control (AHC). Customer has the capability to cut stainless steel with the Water Injection Control
(WIC), and underwater with the help of Air Curtain (A/C).

Shield Gas Box
p/n 0558010155
The Shield Gas Box selects dierent gases (Air, N2, O2, CH4) to mix shield
gas (SG), plasma gas 1 (PG1), and plasma gas 2 (PG2). The selections are
done through a group of solenoids integrated on a manifold. The ICH
sends commands through CAN-bus to operate all these solenoids. The
gas output of the Shield Gas Box is monitored and fed back through the
CAN-bus to ICH for self-diagnosis. Also, the Shield Gas Box controls the
solenoid for operation of the Air Curtain.
The default power input to Shield Gas Box is 230VAC. However, the Shield Gas Box input power is customer selectable, between 115 VAC and 230 VAC. This is accomplished by changing the input power switch inside the Shield
Gas Box. The Shield Gas Box provides 24VDC and 24VAC power for the Plasma Gas Box.

Plasma Gas Box
p/n 0558010156
The Plasma Gas Box regulates the output of the plasma gas (PG) selected
from the four gas inlets (Argon, H35, PG1 and PG2). It is powered by 24 Volts
(AC and DC) from the Shield Gas Box and receives commands via the CANbus directly from the ICH.
Like the Shield gas box, the gas output of the Plasma Gas Box is monitored and fed back through the CAN-bus
to ICH for self-diagnosis.

Description
NOTE:
The PT-36 Torch is shipped with hose lengths that will not allow the Plasma Gas Box to be mounted more than
two meters (6.6 feet) away from the torch. Please make sure the routing of the standard hoses will allow them to
bend and connect properly before permanently mounting the Plasma Gas Box.
If additional distance between the torch and box is required the standard torch hose assembly will need extension hoses to create longer lengths. Extension hoses can be ordered to connect to the existing hose assembly.
The longer hose lengths will require that the pierce time be increased and a longer lead-in time must be specied. This is due to the additional time required to purge the N2 start gas from the hose before the O2 cut gas
becomes aective. This condition occurs when cutting carbon steel with oxygen.

Remote Arc Starter (RAS)
p/n 0558011591
The Remote Arc Starter is more commonly referred to as the RAS
Box. The RAS box provides a voltage feedback to the plasma torch
lift. This voltage is used to regulate the torch height while cutting,
maintaining the proper height of the torch above the work piece.
Within the RAS box there is a High Frequency/Voltage Divider circuit board which provides pilot arc ionization and voltage divider
functions to regulate torch height.
Coolant connections and torch power connections are made within
the RAS box and provide an interface between the power supply,
coolant circulator and the torch.

Air Curtain (A/C)
Description
p/n 37440
The Air Curtain is a device used to improve the performance of plasma arc when cutting underwater. The device
mounts onto the torch and produces a curtain of air. This allows the plasma arc to operate in a relatively dry zone
to reduce noise, fume, and arc radiation, even though the torch has been submerged.
The Air Curtain requires a source of compressed air that needs to be clean, dry and oil-free. It should be delivered
at 80 psi @ 1200 cfh (5.5 bar @ 34 CMH).

Description
Water Injection Control (WIC)
p/n 0558009370
The Water Injection Control (WIC) regulates the ow of cut water
supplied to the plasma torch. This water is used as a shield in
the cutting process. This shield assists in forming the plasma arc
and also cools the cut surface. The selection and output of cut
water is performed and controlled by the ICH. The WIC consists
of a water regulator, pump and a closed feedback loop between
proportional valve and ow sensor. This is controlled by a local
Process Control Unit (PCU). The PCU communicates via CAN to
the ICH while controlling the proportional and solenoid valves.
The WIC is monitored and sends feedback signals through the CAN bus to the ICH for diagnostic purposes.
For more detailed information on the Water Injection Control (WIC), see manual #0558009491.

Automatic Height Control (AHC)
p/n 0560947166
The B4 lift assembly provides vertical motion for the PT-36 plasma torch, using a typical motor, screw, and slide conguration. The motor turns an enclosed spindle screw,
which in turn raises/lowers the lifting plate along linear rails. Directional commands
given from the plasma controller determine the direction of the travel. Fixed limit
switches are included to prevent upper and lower lift’s over travel.
The lift assembly also contains components necessary to control height over work
surfaces; initial, piercing, and cutting heights are encoder controlled during the plasma cycle. During part production, height is automatically controlled by taking voltage measurements between the torch electrode and work surface.
The B4 lifts utilize an Omni Soft Touch® assembly to protect the system during station crashes. Proximity switches monitor torch position in the torch holder. If the
torch is jarred in any direction, the process will stop and an error report will be sent
to the controller.

Grounding
Introduction
Machine grounding is an important part of the installation process, which can be greatly simplied if prepared
in advance. The most dicult part of the grounding process is designing and installing a low impedance Earth
ground rod. However, the better the Earth ground rod, the less chance there is of having electromagnetic
interference problems after the installation is complete.
Most national electric codes address grounding for the purpose of re prevention and short circuit protection;
they do not address equipment protection and electromagnetic interference noise reduction. Therefore, this
manual presents more stringent requirements for machine grounding.
WARNING
Electric Shock Hazard.
Improper grounding can cause severe injury
or death.
Improper grounding can damage machine
electrical components.
Machine must be properly grounded before
putting it into service.
The cutting table must be connected to
machine earth grounding rod.

Grounding Overview
There are three parts to a ground system;
•Component or "chassis" ground
•Earth ground
•Protective Earth ground
Component grounding connects all pieces to a
single component, like the machine chassis, which
is then connected to a common point known as the
star point. This provides a path for electromagnetic
interference (EMI) from the enclosure to ground.
An earth ground provides a electromagnetic
interference (EMI) to return to its source.
A protective earth (PE) ground provides a safe path
for fault current. Without a properly grounded
system, an unintended path through people or
sensitive equipment may be found, resulting in
serious injury, death, and/or premature equipment
failure.
A common symbol used to identify
an earth ground on drawings.
A common symbol used to identify
a protective earth (PE) ground.
This section focuses on machines with a plasma
cutting system. Machines with plasma cutting
capability are particularly prone to electromagnetic
interference problems and often utilize dangerous
voltages and currents. All machines must have
electrical components grounded and attached to
an earth ground, regardless of process type (shape
cutting, marking, or other material preparation).
76
Basic Layout
InstallatIon
The electrical ground layout is similar for both large and small machines. The chassis ground , plasma
positive electrical lead and the rail ground cables are attached to a common point on the cutting
table. This common connection is referred to as a star point (see illustration below). One cable connects
the star point to the Earth ground rod . The size of ground cables is dependant on the maximum current
output of the plasma power supply . Specication of cable sizes is discussed later in this manual. Some
country standards or directives require a separate ground rod for the plasma power supply. Consult your
machine schematics for more information.

•plasma current return path
•plasma system safety ground
•utility power electrical ground
•cutting machine chassis ground
•rail system safety ground.
Ensure provisions are made during the installation for each of these elements for creating a complete ground
system.
Plasma Current Return Path
The return path ground cable is the most important element of the ground system. It completes the path for
the plasma current. Solid, low impedance, well maintained electrical connections are a necessity.
The plasma cutting current is generated by the plasma power supply . A welding cable carries this current
from the negative (-) connection in the plasma power supply through the x axis cable chain to the
torch. The current then arcs to the work piece on the cutting table. The current path must be closed so
that the current can easily return to its source. This is done by connecting the cutting table to the positive (+)
connection on the plasma power supply. If the return path ground cable is not connected, the plasma
system will not work. There will be no way for the arc to establish between the torch and the work piece. If
the cable is connected, but the connections have a very high resistance, it will limit the current of the arc, and
cause dangerous voltage levels between system components.

The only way to ensure that all components are at the same voltage level (same potential), and thus eliminate
the possibility of being shocked, is to ensure that all interconnections are making good electrical contact.
Good electrical contact requires that connections are made with bare metal to metal contact, the connections
are very tight, and are protected from rust and corrosion. Use a grinder or wire wheel to clean all paint, rust,
and dirt from the surface when connecting cable lugs to any metal surface. Use an electrical joint compound
between cable lugs and metal surfaces to prevent future rust and corrosion. Use the largest size bolts, nuts,
and washers possible, and tighten fully. Use lock washers to ensure that connections stay tight.
Plasma System Safety Ground
The plasma system safety ground (or ground rod)
serves several important purposes. It provides:
•Frame voltage for personnel safety by ensuring
that there are no potential dierences between
system components and building components.
•A stable signal reference for all digital and analog
electrical signals on the cutting machine.
•Helps control electromagnetic Interference (or
EMI).
•Provides a discharge path for short circuits and
high voltage spikes, such as those caused by
lightening strikes.

There are many misconceptions about the ground rod, and the role it plays in reducing electromagnetic
interference. In theory, the ground rod is present to eliminate possible potential dierences between
equipment and building structures. However many people believe that the ground rod allows all radio
frequency noise to be absorbed and disappear into the Earth. Experience has shown that a good ground
rod will eliminate radio frequency noise problems.

Rail System Safety Ground
The rail system safety ground makes sure that the
entire rail is at ground potential, eliminating any
possible shock hazard, and providing backup for the
machine chassis ground in case of a plasma current
short circuit. All four corners of the rail system should
be connected to the cutting table.

Earth Ground Rod
The best way to make sure that your Earth ground connection is optimized is to enlist the services of a
professional. There are a number of engineering rms which specializes in designing and installing Earth
grounding systems. However, if this option cannot be used, then there are several things which can be done to
ensure that your Earth ground connection is good:
Ground Rod
The ground rod itself can be optimized in two ways: length and diameter. The longer the grounding rod,
the better the connection. The same is true for diameter: the larger the diameter, the better the connection.
However, if the soil resistance is very low, then a ground rod longer than 3m [10 feet] does not make a
signicant dierence. Since soil resistivity is rarely as good as it could be, a standard grounding rod should be
25mm [1 inch] in diameter and 6m [20 feet] long.
Soil Resistivity
Soil resistivity can be changed in two ways: by altering the mineral content, the moisture content, or both.
The ideal solution to poor soil resistivity is to excavate the immediate area and backll with conditioned soil
additives. In extremely dry areas, the moisture content can be improved by installing a drip system which
continually moisturizes the soil surrounding the ground rod. A crude way of aecting soil moisture and content
is to use salt water, or rock salt to condition the surrounding soil.

Utility Power Electrical Ground
The utility power electrical ground must accompany all 3 phase and single phase power feeds. This electrical
ground provides the proper reference for all incoming power. Failure to provide this ground is a violation of
most electrical codes, and a serious safety hazard.
Depending on the 3 phase power arrangement (either a “Delta” or a “Y”), the line to ground voltage may be
equal to, or less than the line to line voltage. A problem exists any time the line to ground voltage exceeds any
individual line to line voltage (dierence in potential). Contact your local utility company if you are not sure
that your 3 phase power has a proper electrical ground. Make sure that your electrical contractor properly
installs the electrical ground wire with all 3 phase and single phase power feeds.
The electrical ground must be connected to the appropriate terminal inside of the plasma power supply. Size

Multiple Ground Rods
There are a number of reasons why multiple ground rods should not be used. While installing multiple rods
may improve a safety ground or lightening ground, it oers no advantage for electromagnetic interference
reduction, and can cause more problems than it is worth.
The problem with multiple ground rods is that each rod uses an “interfacing Electromagnetic Interference

Multiple ground rods should be avoided if possible.
However, if all other avenues have been explored

DANGER
Hydrogen explosion hazard! Read the following before attempting to cut with a water table.
A hazard exists whenever a water table is used for plasma arc cutting. Severe explosions have resulted from the accumulation of hydrogen beneath the plate being cut. Thousands of dollars in property damage has been caused by these
explosions. Personal injury or death could result from such an explosion. The best available information indicates that
three possible sources of hydrogen exists in water tables:
1. Molten Metal Reaction
Most of the hydrogen is liberated by a fast reaction of molten metal from the kerf in the water to form metallic ox-
ides. This reaction explains why reactive metals with greater anity for oxygen, such as aluminum and magnesium,
release greater volumes of hydrogen during the cut than does iron or steel. Most of this hydrogen will come to the
surface immediately, but some will cling to small metallic particles. These particles will settle to the bottom of the
water table and the hydrogen will gradually bubble to the surface.
2. Slow Chemical Reaction
Hydrogen may also result from the slower chemical reactions of cold metal particles with the water, dissimilar metals,
or chemicals in the water. The hydrogen gradually bubbles to the surface.
3. Plasma Gas
Hydrogen may come from the plasma gas. At currents over 750 amps, H-35 is used as cut gas. This gas is 35% hydro-
gen by volume and a total of about 125 cfh of hydrogen will be released.
Regardless of the source, the hydrogen gas can collect in pockets formed by the plate being cut and slats on the
table, or pockets from warped plate. There can also be accumulation of hydrogen under the slag tray or even in the
air reservoir, if these are part of the table design. The hydrogen, in the presence of oxygen or air, can then be ignited
by the plasma arc or a spark from any source.
4. Follow these practices to reduce hydrogen generation and accumulation:
A. Clean the slag (especially ne particles) from the bottom of the table frequently. Rell the table with clean water.
B. Do not leave plates on the table overnight or a weekend.
C. If a water table has been unused for several hours, vibrate it in some way before the rst plate is laid in position.
This will allow accumulated hydrogen in the refuse to break loose and dissipate before it is conned by a plate
on the table. This might be accomplished by laying the rst plate onto the table with a slight jolt, then raising
the plate to permit hydrogen to escape before it is nally set down for cutting.
D. If cutting above water, install fans to circulate air between the plate and the water surface.
E. If cutting underwater, agitate the water under the plate to prevent accumulation of hydrogen. This can be done
by aerating the water using compressed air.
F. If possible, change the level of the water between cuts to dissipate accumulated hydrogen.
G. Maintain pH level of the water near 7 (neutral). This reduces the rate of chemical reaction between water and
metals.

WARNING
Possible explosion hazard from plasma cutting aluminum-lithium alloys!
Aluminum-Lithium (Al-Li) alloys are used in the aerospace industry because of 10% weight savings over conventional
aluminum alloys. It has been reported that molten Al-Li alloys can cause explosions when they come into contact with
water. Therefore, plasma cutting of these alloys should not be attempted in the presence of water. These alloys should
only be dry cut on a dry table. Alcoa has determined that "dry" cutting on a dry table is safe and gives good cutting results.
DO NOT dry cut over water. DO NOT water injection cut.
The following are some of the Al-Li alloys currently available:
Alithlite (Alcoa) X8192 (Alcoa)
Alithally (Alcoa) Navalite (U. S. Navy)
2090 Alloy (Alcoa) Lockalite (Lockheed)
X8090A (Alcoa) Kalite (Kaiser)
X8092 (Alcoa) 8091 (Alcan)
For additional details and information on the safe use from the hazards associated with these alloys, contact your aluminum supplier.
Do Not Cut Underwater With H-35! Dangerous buildup of hydrogen gas is possible in the water table.
Hydrogen gas is extremely explosive. Reduce the water level to 4 inches minimum below the workpiece.
Vibrate plate, stir air and water frequently to prevent hydrogen gas buildup.

•See Description and Installation sections for gas control and startup procedures.
Mirror Cutting
When mirror cutting, a reverse swirl gas bae and reverse diuser are required. These reverse parts will “spin” the gas in the
opposite direction, reversing the “good” side of the cut.

Cut Quality
Causes aecting cut quality are interdependent. Changing one variable aects all others. Determining a solution may be dicult. The following guide oers possible solutions to dierent undesirable cutting results. To
begin select the most prominent condition:
•Cut Angle, negative or positive
•Cut Flatness
•Surface Finish
•Dross
•Dimensional Accuracy
Usually the recommended cutting parameters will give optimal cut quality, occasionally conditions may vary
enough that slight adjustments will be required. If so:
•Make small incremental adjustments when making corrections.
•Adjust Arc Voltage in 5 volt increments, up or down as required.
•Adjust cutting speed 5% or less as required until conditions improve.
