SAFETY PRECAUTIONS
Safety Precautions
1.1
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.
Safety - English
FIRES AND EXPLOSIONS -- Heat from
flames and arcs can start fires. Hot
slag or sparks can also cause fires and
explosions. Therefore:
1. Remove all combustible materials well away from
the work area or cover the materials with a protective non-flammable covering. Combustible materials
include wood, cloth, sawdust, liquid and gas fuels,
solvents, paints and coatings, paper, etc.
2. Hot sparks or hot metal can fall through cracks or
crevices in floors or wall openings and cause a hidden smoldering fire or fires on the floor below. Make
certain that such openings are protected from hot
sparks and metal.“
3. Do not weld, cut or perform other hot work until the
workpiece has been completely cleaned so that there
are no substances on the workpiece which might
produce flammable or toxic vapors. Do not do hot
work on closed containers. They may explode.
4. Have fire extinguishing equipment handy for instant
use, such as a garden hose, water pail, sand bucket,
or portable fire extinguisher. Be sure you are trained
in its use.
5.Do not use equipment beyond its ratings. For example, overloaded welding cable can overheat and
create a fire hazard.
6. After completing operations, inspect the work area
to make certain there are no hot sparks or hot metal
which could cause a later fire. Use fire watchers when
necessary.
7. For additional information, refer to NFPA Standard
51B, "Fire Prevention in Use of Cutting and Welding
Processes", available from the National Fire Protection Association, Batterymarch Park, Quincy, MA
02269.
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 fitted with the correct filter and
cover plates to protect your eyes, face, neck, and
ears from sparks and rays of the arc when operating
or observing operations. Warn bystanders not to
watch the arc and not to expose themselves to the
rays of the electric-arc or hot metal.
3. Wear flameproof gauntlet type gloves, heavy longsleeve shirt, cuffless trousers, high-topped shoes,
and a welding helmet or cap for hair protection, to
protect against arc rays and hot sparks or hot metal.
A flameproof apron may also be desirable as protection against radiated heat and sparks.
4. Hot sparks or metal can lodge in rolled up sleeves,
trouser cuffs, or pockets. Sleeves and collars should
be kept buttoned, and open pockets eliminated from
the front of clothing.
5.Protect other personnel from arc rays and hot
sparks with a suitable non-flammable partition or
curtains.
6. Use goggles over safety glasses when chipping slag
or grinding. Chipped slag may be hot and can fly far.
Bystanders should also wear goggles over safety
glasses.
ELECTRICAL SHOCK -- Contact with
live electrical parts and ground can
cause severe injury or death. DO NOT
use AC welding current in damp areas,
if movement is confined, or if there is
danger of falling.
5
SECTION 1
SAFETY PRECAUTIONS
1. Be sure the power source frame (chassis) is connected to the ground system of the input power.
3.Welders should use the following procedures to
minimize exposure to EMF:
2.Connect the workpiece to a good electrical
ground.
A.Route the electrode and work cables together.
Secure them with tape when possible.
3. Connect the work cable to the workpiece. A poor
or missing connection can expose you or others
to a fatal shock.
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.
4. Use well-maintained equipment. Replace worn or
damaged cables.
5. Keep everything dry, including clothing, work area,
cables, torch/Piston, and power source.
D. Connect the work cable to the workpiece as close
as possible to the area being welded.
6. Make sure that all parts of your body are insulated
from work and from ground.
E.Keep welding power source and cables as far
away from your body as possible.
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.
Therefore:
9. Turn off the power before removing your gloves.
FUMES AND GASES -- Fumes and
gases, can cause discomfort or harm,
particularly in confined spaces. Do
not breathe fumes and gases. Shielding gases can cause asphyxiation.
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.
10. Refer to ANSI/ASC Standard Z49.1 (listed on
next page) for specific grounding recommendations. Do not mistake the work lead for a ground
cable.
ELECTRIC AND MAGNETIC FIELDS — May be dangerous. Electric current flowing through
any conductor causes localized Electric and Magnetic Fields (EMF). Welding and cutting current creates EMF
around welding cables and welding
machines. Therefore:
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.
1.Welders having pacemakers should consult their
physician before welding. EMF may interfere with
some pacemakers.
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.
2. Exposure to EMF may have other health effects which
are unknown.
4. Refer to ANSI/ASC Standard Z49.1 (see listing below)
for specific ventilation recommendations.

INCENDIES ET EXPLOSIONS -- La chaleur provenant des flammes ou de l'arc peut
provoquer un incendie. Le laitier incandescent ou les étincelles peuvent
également provoquer un incendie ou
une explosion. Par conséquent :
AVERTISSEMENT : Ces règles de sécurité
ont pour but d'assurer votre protection. Ils
récapitulent les informations de précaution 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
fiches 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.
1. Éloignez suffisamment tous les matériaux combustibles de l'aire de travail et recouvrez les matériaux
avec un revêtement protecteur ininflammable. 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 fissures 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 inflammables 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 surchauffer 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.
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 filtrants et de plaques
protectrices appropriées afin 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 afin 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
ininflammable afin 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 ininflammable.
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.
CHOC ÉLECTRIQUE -- Le contact avec
des pièces électriques ou les pièces de
mise à la terre sous tension peut causer
des blessures graves ou mortelles. 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 afin 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 effectuer 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
spécifiques concernant les procédures de mise à
la terre. Ne pas confondre le câble de masse avec
le câble de mise à la terre.
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 efficaces. Ne
respirez pas les vapeurs de ces matériaux.
2.N'effectuez 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 afin
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 spécifiques
concernant la ventilation.
CHAMPS ÉLECTRIQUES ET MAGNÉTIQUES — comportent un risque de
danger. Le courant électrique qui
passe dans n'importe quel conducteur 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 magnétiques peut avoir des effets néfastes inconnus pour
la santé.

SÉCURITÉ
5. AVERTISSEMENT : Ce produit, lorsqu'il est utilisé
dans une opération de soudage ou de
coupage, dégage des vapeurs ou des
gaz contenant des chimiques considéres par l'état de la Californie comme
étant une cause des malformations
congénitales et dans certains cas, du
cancer. (California Health & Safety
Code §25249.5 et seq.)
ENTRETIEN DE L'ÉQUIPEMENT -- Un équipement entretenu de façon défectueuse ou
inadéquate peut causer des blessures
graves ou mortelles. Par conséquent :
1.Efforcez-vous de toujours confier les tâches
d'installation, de dépannage et d'entretien à un
personnel qualifié. N'effectuez aucune réparation
électrique à moins d'être qualifié à cet effet.
2.Avant de procéder à une tâche d'entretien à
l'intérieur de la source d'alimentation, débranchez
l'alimentation électrique.
3.Maintenez les câbles, les fils de mise à la terre,
les branchements, le cordon d'alimentation et la
source d'alimentation en bon état. N'utilisez jamais un équipement s'il présente une défectuosité
quelconque.
4. N'utilisez pas l'équipement de façon abusive. Gardez
l'équipement à l'écart de toute source de chaleur,
notamment des fours, de l'humidité, des flaques
d'eau, de l'huile ou de la graisse, des atmosphères
corrosives et des intempéries.
5.Laissez en place tous les dispositifs de sécurité et
tous les panneaux de la console et maintenez-les
en bon état.
6.Utilisez l'équipement conformément à son usage
prévu et n'effectuez aucune modification.
MANIPULATION DES CYLINDRES -La manipulation d'un cylindre, sans
observer les précautions nécessaires,
peut produire des fissures et un
échappement dangereux des gaz.
Une brisure soudaine du cylindre, de la soupape ou
du dispositif de surpression peut causer des blessures graves ou mortelles. Par conséquent :
1. Utilisez toujours le gaz prévu pour une opération
et le détendeur approprié conçu pour utilisation
sur les cylindres de gaz comprimé. N'utilisez jamais
d'adaptateur. Maintenez en bon état les tuyaux et
les raccords. Observez les instructions d'opération
du fabricant pour assembler le détendeur sur un
cylindre de gaz comprimé.
2.Fixez les cylindres dans une position verticale, à
l'aide d'une chaîne ou une sangle, sur un chariot
manuel, un châssis de roulement, un banc, un mur,
une colonne ou un support convenable. Ne fixez
jamais un cylindre à un poste de travail ou toute autre
dispositif faisant partie d'un circuit électrique.
3.Lorsque les cylindres ne servent pas, gardez les
soupapes fermées. Si le détendeur n'est pas branché, assurez-vous que le bouchon de protection de
la soupape est bien en place. Fixez et déplacez les
cylindres à l'aide d'un chariot manuel approprié.
Toujours manipuler les cylindres avec soin.
4.Placez les cylindres à une distance appropriée
de toute source de chaleur, des étincelles et des
flammes. Ne jamais amorcer l'arc sur un cylindre.

4.0 Cutting with the PT-37
Use the following procedures to cut with the PT-37 torch.
4.1 Installing Consumables
Tests have shown that with proper use of the torch within rated operating conditions (especially arc current and
gas flow rate), the torch consumable parts do not become loose if they are firmly installed. Torch damage and
overheating can be caused by loose parts.
1. Make sure that the wall disconnect switch is off.
2. Tighten electrode and retaining/shield cup fully at each consumable change or inspection.
3. Check consumable tightness at beginning of each work period, even if everything was working normally at the end of the previous period.
Note:
Torch Body
Assembly
Ensure that the electrode/torch body
seat and piston are clean and free of
dust or dirt. Debris may prevent mating surfaces from having solid contact.
Gas Baffle (30-70A)
Note:
Electrode/Torch
Body Seat
Firm tightening of the electrode by
hand is sufficient, the use of tools such
as wrenches or pliers is not required or
recommended.
Piston
Gas Baffle (90/100A)
Note:
Electrode
Torch damage and overheating can
be caused by loose parts. Arc tracking
indicates loose parts. Make sure retaining cup is tightened fully. Parts damaged by arcing will cause destruction
of torch and must be replaced.

MAINTENANCE
WARNING
BEFORE ANY MAINTENANCE IS ATTEMPTED ON THIS TORCH, MAKE
SURE THE POWER SWITCH ON THE CONSOLE IS IN THE OFF POSITION
AND THE PRIMARY INPUT POWER IS DEENERGIZED.
5.0General
A. Periodically check torch head assembly. Replace if worn or damaged.
B. Torch cable should be inspected periodically. If there are any cuts through the protective sheath or wire
insulation, replace the cable.
5.1
Dirt or Contamination
Dirt or other contamination in the torch and loose consumable parts can cause premature failure of the PT-37
Torch through internal arcing. To avoid this, users are instructed to do the following: Ensure that clean, dry, and
oil-free air is being used. Wipe the retaining cup clean with a cloth before installing each fresh set of consumables.
The ability of the retaining cup to resist arc tracking over its surface is reduced when dirt or other contamination
is allowed to collect there.
5.2
Inspection, Cleaning and Replacement of Consumables
1. Bring torch to a position where it is easily
accessed by machine operator, in its normal
vertical position.
Torch Body
Assembly
Gas Baffle (30-70A)
2. Unscrew the retaining cup and lower it
away from the torch, allowing nozzle to
remain with retaining cup.
Electrode/Torch

Note:
The nozzle and electrode will generally
wear at the same rate. For best performance, replace together.

SECTION 5
MAINTENANCE
CAUTION
REPLACE ELECTRODE BEFORE WEAR BECOMES DEEPER THAN .060"
INCH (1.5 MM).
3. Remove the nozzle by tilting retaining cup upside down and pushing nozzle out. Inspect nozzle
for wear. The nozzle orifice should be round at both the entrance and the exit. If the nozzle orifice
is worn in an oval shape or shows other signs of damage at either end, it should be replaced. The
inside of the nozzle may have light gray deposits from the electrode. These may be removed with
steel wool but care must be taken to remove all traces of the steel wool afterward.
4. If the electrode has a pit which is more than .06" (1.5mm) deep at its center, it must be replaced.
This is done by unscrewing the electrode in a counter-clockwise direction from the piston. If the
electrode is used beyond this recommended wear limit, damage to the torch and power source
may occur. Nozzle life is also greatly reduced when using the electrode below the recommended
limit.
Note:
Gas baffle and retaining/shield cup need to be replaced only if cracked or significant signs of
wear are noticeable. Monthly replacement is generally a good practice.

5. Remove the gas baffle. Inspect it and the piston for signs of damage such as arc tracking or cracking and replace them if necessary.
6. After installing the gas baffle onto the torch body assembly, install electrode by screwing clockwise
into place.
7. Lastly, replace the nozzle and retaining/shield cup by screwing clockwise into place.
Note:
Firm tightening of the electrode by hand is sufficient, the use of tools such as wrenches or pliers
is not required or recommended.
Note:
Retaining Cup

MAINTENANCE
Measuring Torch Gas Flows
If low gas flow is suspected of causing poor cutting performance or short
consumable life, the flow can be checked by using the Plasma Torch Flow
Measuring Kit. The kit includes a hand held rotameter (flowmeter) which
will indicate the gas flow rate exiting the torch. The kit also includes a set
of instructions which should be followed exactly to insure safe and accurate use of the rotameter.
Total air flow rate in the PT-37 should be 475 cfh (13.4 cmh) minimum with
100 amp consumables installed.
