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 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 long-sleeve
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.
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 nonflammable 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 Pro-
--
cesses", 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 confined, or if there is danger of
falling.
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.
9. Turn off the power before removing your gloves.
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:
1. Welders having pacemakers should consult their physician before welding. EMF may interfere with some pacemakers.
2. Exposure to EMF may have other health effects which are
unknown.
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.
10/98
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.
Therefore:
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 specific 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
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 fittings 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 fixtures 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 flames.
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 Jefferson Davis Highway, Arlington,
VA 22202.
§25249.5 et seq.)
EQUIPMENT MAINTENANCE -- Faulty or
improperly maintained equipment can
cause injury or death. Therefore:
1. Always have qualified personnel perform the installation, troubleshooting, and maintenance work. Do not
perform any electrical work unless you are qualified 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.
4. Do not abuse any equipment or accessories. Keep
equipment away from heat sources such as furnaces,
wet conditions such as water puddles, oil or grease,
corrosive atmospheres and inclement weather.
5. Keep all safety devices and cabinet covers in position
and in good repair.
6. Use equipment only for its intended purpose. Do not
modify it in any manner.

PRÉCAUTIONS DE SÉCURITÉ
AVERTISSEMENT: Ces règles de sécurité ont pour
objet d assurer votre protection. Veillez à lire et à
observer les précautions énoncées ci-dessous avant de
monter l équipement ou de commercer à lutiliser. Tout
défaut dobservation de ces précautions risque
dentraîner des blessures graves ou mortelles.
1. PROTECTION INDIVIDUELLE-- Les brûlures de la
peau et des yeux dues au rayonnement de larc
électrique ou du métal incandescent, lors du soudage
au plasma ou à lélectrode ou lors du gougeage à
larc, peuvent savérer plus graves que celles
résultant dune exposition prolongée au soleil. Aussi
convient-il dobserver les précautions suivantes:
a. Portez un écran facial adéquat muni des plaques
protectrices et des verres filtrants appropriés afin de
vous protéger les yeux, le visage, le cou et les
oreilles des étincelles et du rayonnement de larc
électrique lorsque vous effectuez des soudures ou
des coupes ou lorsque vous en observez lexécution.
AVERTISSEZ les personnes se trouvant à proximité
de façon à ce quelles ne regardent pas larc et à ce
quelles ne sexposent pas à son rayonnement, ni à
celui du métal incandescent.
b. Portez des gants ignifugés à crispins, une tunique
épaisse à manches longues, des pantalons sans
rebord, des chaussures à embout dacier et un
casque de soudage ou une calotte de protection,
afin déviter dexposer la peau au rayonnement de
larc électrique ou du métal incandescent. ll est
également souhaitable dutiliser un tablier
ininflammable de façon à se protéger des étincelles
et du rayonnement thermique.
c. Les étincelles ou les projections de métal incandes-
cent risquent de se loger dans des manches
retroussées, des bords relevés de pantalons ou
dans des poches. Aussi convient-il de garder
boutonnés le col et les manches et de porter des
vêtements sans poches à lavant.
d. Protégez des étincelles et du rayonnement de larc
électrique les autres personnes travaillant à proximité
à laide dun écran ininflammable adéquat.
e. Ne jamais omettre de porter des lunettes de sécurité
lorsque vous vous trouvez dans un secteur où lon
effectue des opérations de soudage ou de coupage
à larc. Utilisez des lunettes de sécurité à écrans ou
verres latéraux pour piquer ou meûler le laitier. Les
piquetures incandescentes de laitier peuvent être
projetées à des distances considérables. Les
personnes se trouvant à proximité doivent également
porter des lunettes de protection.
f. Le gougeage à larc et le soudage à larc au plasma
produisent un niveau de bruit extrêmement élevé
(de 100 à 114 dB) et exigent par conséquent
lemploi de dispositifs appropriés de protection auditive.
2. PRÉVENTION DES INCENDES-- Les projections de
laitier incandescent ou détincelles peuvent
provoquer de graves incendies au contact de
matériaux combustibles solides, liquides ou gazeux.
Aussi faut-il observer les précautions suivantes:
a. Éloigner suffisamment tous les matériaux combus-
tibles du secteur où lon exécute des soudures ou
des coupes à larc, à moins de les recouvrir
complètement dune bâche non-inflammable. Ce
type de matériaux comprend notamment le bois, les
vêtements, la sciure, lessence, le kérosène, les
peintures, les solvants, le gaz naturel, lacétylène, le
propane et autres substances combustibles
semblables.
b. Les étincelles ou les projections de métal incandes-
cent peuvent tomber dans des fissures du plancher
ou dans des ouvertures des murs et y déclencher
une ignition lente cachée. Veiller à protéger ces
ouvertures des étincelles et des projections de
métal.
c. Nexécutez pas de soudures, de coupes, dopérations
de gougeage ou autres travaux à chaud à la surface
de barils, bidons, réservoirs ou autres contenants
usagés, avant de les avoir nettoyés de toute trace
de substance susceptible de produire des vapeurs
inflammables ou toxiques.
d. En vue dassurer la prévention des incendies, il
convient de disposer dun matériel dextinction prêt
à servir immédiatement, tel quun tuyau darrosage,
un seau à eau, un seau de sable ou un extincteur
portatif.
e. Une fois le travail à larc terminé, inspectez le
secteur de façon à vous assurer quaucune étincelle
ou projection de métal incandescent ne risque de
provoquer ultérieurement un feu.
3. CHOC ÉLECTRIQUE-- Le gougeage à larc et à larc
au plasma exige lemploi de tensions à vide
relativement importantes; or, celles-ci risquent de
causer des dommages corporels graves et même
mortels en cas dutilisation inadéquate. La gravité
du choc électrique reçu dépend du chemin suivi par
le courant à travers le corps humain et de son
intensité.
a. Ne laissez jamais de surfaces métalliques sous
tension venir au contact direct de la peau ou de
vêtements humides. Veillez à porter des gants bien
secs.
b. Si vous devez effectuer un travail sur une surface
métallique ou dans un secteur humide, veillez à
assu-rer votre isolation corporelle en portant des
gants secs et des chaussures à semelles de caoutchouc et en vous tenant sur une planche ou une
plate-forme sèche.
c. Mettez toujours à la terre le poste de soudage/
coupage en le reliant par un câble à une bonne prise
de terre.
d. Nutilisez jamais de câbles usés ou endommagés.
Ne surchargez jamais le câble. Utilisez toujours un
équipement correctement entretenu.
e. Mettez léquipement hors tension lorsquil nest pas
en service. une mise à la masse accidentelle peut
en effet provoquer une surchauffe de léquipement
et un danger dincendie. Ne pas enrouler ou passer
5
9/97
levage, des câbles de grue ou divers chemins
électriques.
g. Empêchez lapparition de toute humidité, notamment
sur vos vêtements, à la surface de lemplacement de
travail, des câbles, du porte-électrode et du poste de
soudage/coupage. Réparez immédiatement toute fuite
deau.
4. VENTILATION-- La respiration prolongée des fumées
résultant des opérations de soudage/coupage, à
lintérieur, dun local clos, peut provoquer des malaises et des dommages corporels. Aussi convient-il
dobserver les précautions suivantes:
a. Assurez en permanence une aération adéquate de
lemplacement de travail en maintenant une ventilation naturelle ou à laide de moyens mécaniques.
Neffectuez jamais de travaux de soudage ou de
coupage sur des matériaux de zinc, de plomb, de
beryllium ou de cadmium en labsence de moyens
mécaniques de ventilation capables dempêcher
linhalation des fumées dégagées par ces matériaux.
b. Neffectuez jamais de travaux de soudage ou de
coupage à proximité de vapeurs dhydrocarbure chloré
résultant dopérations voisines de dégraissage ou de
pulvérisation. La chaleur dégagée ou le rayonnement
de larc peut déclencher la formation de phosgène -gaz particulièrement toxique -- et dautres gaz irritants, à partir des vapeurs de solvant.
c. Une irritation momentanée des yeux, du nez ou de la
gorge constatée au cours de lutilisation de
léquipement dénote un défaut de ventilation. Arrêtezvous de travailler afin de prendre les mesures nécessaires à lamélioration de la ventilation. Ne poursuivez
pas lopération entreprise si le malaise persiste.
d. Certaines commandes comportent des canalisations
où circule de lhydrogène. Larmoire de commande est
munie dun ventilateur destiné à empêcher la formation de poches dhydrogène, lesquelles présentent un
danger dexplosion; ce ventilateur ne fonctionne que
si linterrupteur correspondant du panneau avant se
trouve placé en position ON (Marche). Veillez à
manuvrer cette commande en vérifiant si le couvercle
est bien en place, de façon à assurer lefficacité de la
ventilation ainsi réalisée. Ne jamais débrancher le
ventilateur.
e. Les fumées produites par lopération de soudage ou
de coupage peuvent savérer toxiques. Aussi est-il
nécessaire de disposer en permanence dun dispositif
adéquat de ventilation de type aspirant, afin déliminer du voisinage de lopérateur tout dégagement de
fumée visible.
f. Consultez les recommandations particulières en matière
de ventilation indiquées à lalinéa 6 de la norme Z49.1
de lAWS.
5. ENTRETIEN DE LÉQUIPEMENT-- Un équipement
entretenu de façon défectueuse ou inadéquate risque
non seulement de réaliser un travail de mauvaise
qualité mais, chose plus grave encore, dentraîner
des dommages corporels graves, voire mortels en
déclenchant des incendies ou des chocs électriques.
Observez par conséquent les précautions suivantes:
a. Efforcez-vous de toujours confier à un personnel qua-
lifié linstallation, le dépannage et lentretien du poste
de soudage et de coupage. Neffectuez aucune
réparation électrique sur léquipement à moins dêtre
qua-lifié à cet effet.
b. Ne procédez jamais à une tâche dentretien
quelconque à lintérieur du poste de soudage/
coupage, avant davoir débranché lalimentation
électrique.
c. Maintenez en bon état de fonctionnement les câbles,
le câble de masse, les branchements, le cordon
dalimentation et le poste de soudage/coupage.
Nutilisez jamais le poste ou léquipement sil présente
une défectuosité quelconque.
d. Prenez soin du poste de soudage et de coupage et
des équipements accessoires. Gardez-les à lécart
des sources de charleur, notamment des fours, de
lhumidité, des flaques deau maintenez-les à labri
des traces dhuile ou de graisse, des atmosphères
corrosives et des intempéries.
e. Laissez en place tous les dispositifs de sécurité et
tous les panneaux de larmoire de commande en
veillant à les garder en bon état.
f. Utilisez le poste de soudage/coupage conformément

SECTION 1 DESCRIPTION AND SPECIFICATIONS
I. DESCRIPTION AND SPECIFICATIONS
The MIG-35 Wire Feeder covered in this literature is designed for short arc, spray arc mig or cored wire welding
with a constant potential (CP) welding power source. In
short arc welding, relatively low voltages and small- diameter wires are used. Wire speed is set so that the
low-voltage arc actually shorts out to the weld puddle
50-200 times a second. The result is a small weld puddle,
with minimum melting of base metal and minimum transfer of heat into the work. Short arc welding can be done
in any position, and used to weld sheet as thin as 1/16-in.
In spray arc welding, heavier wires and higher voltages
are used, and there is no shorting out of the arc. Metal
is transferred in a stream of droplets through the arc. The
weld puddle is larger and out-of-position welding is somewhat more difficult, but higher rates of metal deposition
are possible.
