From Miller to You

Thank you and congratulations on choosing Miller. Now you can get

the job done and get it done right. We know you don’t have time to do

it any other way.

That’s why when Niels Miller first started building arc welders in 1929,

he made sure his products offered long-lasting value and superior

quality. Like you, his customers couldn’t afford anything less. Miller

products had to be more than the best they could be. They had to be

the best you could buy.

Today, the people that build and sell Miller products continue the

tradition. They’re just as committed to providing equipment and

service that meets the high standards of quality and value established

in 1929.

This Owner’s Manual is designed to help you get the most out of your

Miller products. Please take time to read the Safety Precautions. They

will help you protect yourself against potential hazards on the

worksite. We’ve made installation and operation quick and easy. With

Miller, you can count on years of reliable service with proper

maintenance. And if for some reason the unit needs repair, there’s a

Troubleshooting section that will help you figure out what the problem

is, and our extensive service network is there to help fix the problem.

Warranty and maintenance information for your particular model are

also provided.

Miller Electric manufactures a full line of

welders and welding-related equipment. For

1-2. Arc Welding Hazards

The symbols shown below are used throughout this manual

to call attention to and identify possible hazards. When you

see the symbol, watch out, and follow the related instruc-

tions to avoid the hazard. The safety information given be-

low is only a summary of the more complete safety

information found in the Principal Safety Standards listed in

Section 1-5. Read and follow all Safety Standards.

Only qualified persons should install, operate, maintain,

and repair this equipment. A qualified person is defined as

one who, by possession of a recognized degree, certificate,

or professional standing, or who by extensive knowledge,

training and experience, has successfully demonstrated the

ability to solve or resolve problems relating to the subject

matter, the work, or the project and has received safety

training to recognize and avoid the hazards involved.

During operation, keep everybody, especially children,

away.

ELECTRIC SHOCK can kill.

Touching live electrical parts can cause fatal

shocks or severe burns. The electrode and work

circuit is electrically live whenever the output is on.

The input power circuit and machine internal cir-

cuits are also live when power is on. In semiauto-

matic or automatic wire welding, the wire, wire

reel, drive roll housing, and all metal parts touching

the welding wire are electrically live. Incorrectly in-

stalled or improperly grounded equipment is a

hazard.

l Do not touch live electrical parts.

l Wear dry, hole-free insulating gloves and body protection.

l Insulate yourself from work and ground using dry insulating mats

or covers big enough to prevent any physical contact with the work

or ground.

l Do not use AC weld output in damp, wet, or confined spaces, or if

there is a danger of falling.

l Use AC output ONLY if required for the welding process.

l If AC output is required, use remote output control if present on

unit.

l Additional safety precautions are required when any of the follow-

ing electrically hazardous conditions are present: in damp loca-

tions or while wearing wet clothing; on metal structures such as

floors, gratings, or scaffolds; when in cramped positions such as

sitting, kneeling, or lying; or when there is a high risk of unavoid-

able or accidental contact with the workpiece or ground. For these

conditions, use the following equipment in order presented: 1) a

semiautomatic DC constant voltage (wire) welder, 2) a DC manual

(stick) welder, or 3) an AC welder with reduced open-circuit volt-

age. In most situations, use of a DC, constant voltage wire welder

is recommended. And, do not work alone!

l Disconnect input power or stop engine before installing or servic-

ing this equipment. Lockout/tagout input power according to

OSHA 29 CFR 1910.147 (see Safety Standards).

l Properly install, ground, and operate this equipment according to

its Owner’s Manual and national, state, and local codes.

l Always verify the supply ground — check and be sure that input

power cord ground wire is properly connected to ground terminal

in disconnect box or that cord plug is connected to a properly

grounded receptacle outlet.

l When making input connections, attach proper grounding conduc-

tor first — double-check connections.

l Keep cords dry, free of oil and grease, and protected from hot met-

al and sparks.

l Frequently inspect input power cord and ground conductor for

damage or bare wiring — replace immediately if damaged — bare

wiring can kill.

l Turn off all equipment when not in use.

l Do not use worn, damaged, undersized, or repaired cables.

l Do not drape cables over your body.

l If earth grounding of the workpiece is required, ground it directly

with a separate cable.

l Do not touch electrode if you are in contact with the work, ground,

or another electrode from a different machine.

l Use only well-maintained equipment. Repair or replace damaged

parts at once. Maintain unit according to manual.

l Do not touch electrode holders connected to two welding ma-

chines at the same time since double open-circuit voltage will be

present.

l Wear a safety harness if working above floor level.

l Keep all panels and covers securely in place.

l Clamp work cable with good metal-to-metal contact to workpiece

or worktable as near the weld as practical.

l Insulate work clamp when not connected to workpiece to prevent

contact with any metal object.

l Do not connect more than one electrode or work cable to any sin-

gle weld output terminal. Disconnect cable for process not in use.

l Use GFCI protection when operating auxiliary equipment in damp

or wet locations.

SIGNIFICANT DC VOLTAGE exists in inverter power sources

AFTER removal of input power.

l Turn off unit, disconnect input power, and discharge input capaci-

tors according to instructions in Manual before touching any parts.

OM-243477 Page 2

HOT PARTS can burn.

l Do not touch hot parts bare handed.

l Allow cooling period before working on equipment.

l To handle hot parts, use proper tools and/or wear

heavy, insulated welding gloves and clothing to

prevent burns.

FLYING METAL OR DIRT can injure

eyes.

l Welding, chipping, wire brushing, and grinding

cause sparks and flying metal. As welds cool, they

can throw off slag.

l Wear approved safety glasses with side shields even under your

welding helmet.

FUMES AND GASES can be

hazardous.

Welding produces fumes and gases. Breathing

these fumes and gases can be hazardous to your

health.

l Keep your head out of the fumes. Do not breathe the fumes.

l Ventilate the work area and/or use local forced ventilation at the

arc to remove welding fumes and gases. The recommended way

to determine adequate ventilation is to sample for the composition

and quantity of fumes and gases to which personnel are exposed.

l If ventilation is poor, wear an approved air-supplied respirator.

l Read and understand the Safety Data Sheets (SDSs) and the

manufacturer’s instructions for adhesives, coatings, cleaners, con-

sumables, coolants, degreasers, fluxes, and metals.

l Work in a confined space only if it is well ventilated, or while wear-

ing an air-supplied respirator. Always have a trained watchperson

nearby. Welding fumes and gases can displace air and lower the

oxygen level causing injury or death. Be sure the breathing air is

safe.

l Do not weld in locations near degreasing, cleaning, or spraying

operations. The heat and rays of the arc can react with vapors to

form highly toxic and irritating gases.

l Do not weld on coated metals, such as galvanized, lead, or cadmi-

um plated steel, unless the coating is removed from the weld area,

the area is well ventilated, and while wearing an air-supplied respi-

rator. The coatings and any metals containing these elements can

give off toxic fumes if welded.

BUILDUP OF GAS can injure or kill.

l Shut off compressed gas supply when not in use.

l Always ventilate confined spaces or use approved

air-supplied respirator.

ARC RAYS can burn eyes and skin.

Arc rays from the welding process produce intense

visible and invisible (ultraviolet and infrared) rays

that can burn eyes and skin. Sparks fly off from the

weld.

l Wear an approved welding helmet fitted with a proper shade of fil-

ter lenses to protect your face and eyes from arc rays and sparks

when welding or watching (see ANSI Z49.1 and Z87.1 listed in

Safety Standards).

l Wear approved safety glasses with side shields under your

helmet.

l Use protective screens or barriers to protect others from flash,

glare, and sparks; warn others not to watch the arc.

l Wear body protection made from durable, flame-resistant material

(leather, heavy cotton, wool). Body protection includes oil-free

clothing such as leather gloves, heavy shirt, cuffless trousers, high

shoes, and a cap.

WELDING can cause fire or

explosion.

Welding on closed containers, such as tanks,

drums, or pipes, can cause them to blow up.

Sparks can fly off from the welding arc. The flying

sparks, hot workpiece, and hot equipment can cause fires and burns.

Accidental contact of electrode to metal objects can cause sparks, ex-

plosion, overheating, or fire. Check and be sure the area is safe be-

fore doing any welding.

l Remove all flammables within 35 ft (10.7 m) of the welding arc. If

this is not possible, tightly cover them with approved covers.

l Do not weld where flying sparks can strike flammable material.

l Protect yourself and others from flying sparks and hot metal.

l Be alert that welding sparks and hot materials from welding can

easily go through small cracks and openings to adjacent areas.

l Watch for fire, and keep a fire extinguisher nearby.

l Be aware that welding on a ceiling, floor, bulkhead, or partition can

cause fire on the hidden side.

l Do not cut or weld on tire rims or wheels. Tires can explode if

heated. Repaired rims and wheels can fail. See OSHA 29 CFR

1910.177 listed in Safety Standards.

l Do not weld on containers that have held combustibles, or on

closed containers such as tanks, drums, or pipes unless they are

properly prepared according to AWS F4.1 and AWS A6.0 (see

Safety Standards).

l Do not weld where the atmosphere can contain flammable dust,

gas, or liquid vapors (such as gasoline).

l Connect work cable to the work as close to the welding area as

practical to prevent welding current from traveling long, possibly

unknown paths and causing electric shock, sparks, and fire

hazards.

l Do not use welder to thaw frozen pipes.

l Remove stick electrode from holder or cut off welding wire at con-

tact tip when not in use.

l Wear body protection made from durable, flame-resistant material

(leather, heavy cotton, wool). Body protection includes oil-free

clothing such as leather gloves, heavy shirt, cuffless trousers, high

shoes, and a cap.

l Remove any combustibles, such as a butane lighter or matches,

from your person before doing any welding.

l After completion of work, inspect area to ensure it is free of sparks,

glowing embers, and flames.

l Use only correct fuses or circuit breakers. Do not oversize or by-

pass them.

l Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B

for hot work and have a fire watcher and extinguisher nearby.

l Read and understand the Safety Data Sheets (SDSs) and the

manufacturer’s instructions for adhesives, coatings, cleaners, con-

sumables, coolants, degreasers, fluxes, and metals.

NOISE can damage hearing.

Noise from some processes or equipment can

damage hearing.

l Wear approved ear protection if noise level is high.

ELECTRIC AND MAGNETIC FIELDS

(EMF) can affect Implanted Medical

Devices.

l Wearers of Pacemakers and other Implanted Med-

ical Devices should keep away.

l Implanted Medical Device wearers should consult their doctor and

the device manufacturer before going near arc welding, spot weld-

ing, gouging, plasma arc cutting, or induction heating operations.

OM-243477 Page 3

CYLINDERS can explode if

damaged.

Compressed gas cylinders contain gas under high

pressure. If damaged, a cylinder can explode.

Since gas cylinders are normally part of the weld-

ing process, be sure to treat them carefully.

l Protect compressed gas cylinders from excessive heat, mechani-

cal shocks, physical damage, slag, open flames, sparks, and arcs.

l Install cylinders in an upright position by securing to a stationary

support or cylinder rack to prevent falling or tipping.

l Keep cylinders away from any welding or other electrical circuits.

l Never drape a welding torch over a gas cylinder.

l Never allow a welding electrode to touch any cylinder.

l Never weld on a pressurized cylinder — explosion will result.

l Use only correct compressed gas cylinders, regulators, hoses,

and fittings designed for the specific application; maintain them

and associated parts in good condition.

l Turn face away from valve outlet when opening cylinder valve. Do

not stand in front of or behind the regulator when opening the

valve.

l Keep protective cap in place over valve except when cylinder is in

use or connected for use.

l Use the proper equipment, correct procedures, and sufficient

number of persons to lift, move, and transport cylinders.

l Read and follow instructions on compressed gas cylinders, asso-

ciated equipment, and Compressed Gas Association (CGA) publi-

cation P-1 listed in Safety Standards.

1-3. Additional Hazards For Installation, Operation, And Maintenance

1-6. EMF Information

Electric current flowing through any conductor causes localized elec-

tric and magnetic fields (EMF). The current from arc welding (and al-

lied processes including spot welding, gouging, plasma arc cutting,

and induction heating operations) creates an EMF field around the

welding circuit. EMF fields can interfere with some medical implants,

e.g. pacemakers. Protective measures for persons wearing medical

implants have to be taken. For example, restrict access for passers

−by or conduct individual risk assessment for welders. All welders

should use the following procedures in order to minimize exposure to

EMF fields from the welding circuit:

1. Keep cables close together by twisting or taping them, or using a

cable cover.

2. Do not place your body between welding cables. Arrange cables

to one side and away from the operator.

3. Do not coil or drape cables around your body.

4. Keep head and trunk as far away from the equipment in the weld-

ing circuit as possible.

5. Connect work clamp to workpiece as close to the weld as

possible.

6. Do not work next to, sit or lean on the welding power source.

7. Do not weld whilst carrying the welding power source or wire

feeder.

About Implanted Medical Devices:

Implanted Medical Device wearers should consult their doctor and the

device manufacturer before performing or going near arc welding,

spot welding, gouging, plasma arc cutting, or induction heating opera-

tions. If cleared by your doctor, then following the above procedures

is recommended.

plus particulièrement les enfants.

UNE DÉCHARGE ÉLECTRIQUE peut

entraîner la mort.

Le contact d’organes électriques sous tension peut

provoquer des accidents mortels ou des brûlures

graves. Le circuit de l’électrode et de la pièce est

sous tension lorsque le courant est délivré à la sor-

tie. Le circuit d’alimentation et les circuits internes

de la machine sont également sous tension

lorsque l’alimentation est sur Marche. Dans le

mode de soudage avec du fil, le fil, le dérouleur, le

bloc de commande du rouleau et toutes les parties

métalliques en contact avec le fil sont sous tension électrique. Un

équipement installé ou mis à la terre de manière incorrecte ou impro-

pre constitue un danger.

l Ne pas toucher aux pièces électriques sous tension.

l Porter des gants isolants et des vêtements de protection secs et

sans trous.

l S’isoler de la pièce à couper et du sol en utilisant des housses ou

des tapis assez grands afin d’éviter tout contact physique avec la

pièce à couper ou le sol.

l Ne pas utiliser de sortie de soudage CA dans des zones humides

ou confinées ou s’il y a un risque de chute.

l Se servir d’une source électrique à courant électrique UNIQUE-

MENT si le procédé de soudage le demande.

l Si l’utilisation d’une source électrique à courant électrique s’avère

nécessaire, se servir de la fonction de télécommande si l’appareil

en est équipé.

l D’autres consignes de sécurité sont nécessaires dans les condi-

tions suivantes : risques électriques dans un environnement hu-

mide ou si l’on porte des vêtements mouillés ; sur des structures

métalliques telles que sols, grilles ou échafaudages ; en position

coincée comme assise, à genoux ou couchée ; ou s’il y a un risque

élevé de contact inévitable ou accidentel avec la pièce à souder

ou le sol. Dans ces conditions, utiliser les équipements suivants,

dans l’ordre indiqué : 1) un poste à souder DC à tension constante

(à fil), 2) un poste à souder DC manuel (électrode) ou 3) un poste

à souder AC à tension à vide réduite. Dans la plupart des situ-

ations, l’utilisation d’un poste à souder DC à fil à tension constante

est recommandée. En outre, ne pas travailler seul !

l Couper l’alimentation ou arrêter le moteur avant de procéder

à l’installation, à la réparation ou à l’entretien de l’appareil. Déver-

rouiller l’alimentation selon la norme OSHA 29 CFR 1910.147

(voir normes de sécurité).

l Installez, mettez à la terre et utilisez correctement cet équipement

conformément à son Manuel d’Utilisation et aux réglementations

nationales, gouvernementales et locales.

l Toujours vérifier la terre du cordon d’alimentation. Vérifier et s’as-

surer que le fil de terre du cordon d’alimentation est bien raccordé

à la borne de terre du sectionneur ou que la fiche du cordon est

raccordée à une prise correctement mise à la terre.

l En effectuant les raccordements d’entrée, fixer d’abord le conduc-

teur de mise à la terre approprié et contre-vérifier les connexions.

l Les câbles doivent être exempts d’humidité, d’huile et de graisse;

protégez-les contre les étincelles et les pièces métalliques

chaudes.

l Vérifier fréquemment le cordon d’alimentation et le conducteur de

mise à la terre afin de s’assurer qu’il n’est pas altéré ou dénudé -,

le remplacer immédiatement s’il l’est -. Un fil dénudé peut entraî-

ner la mort.

l L’équipement doit être hors tension lorsqu’il n’est pas utilisé.

l Ne pas utiliser des câbles usés, endommagés, de grosseur insuffi-

sante ou mal épissés.

l Ne pas enrouler les câbles autour du corps.

l Si la pièce soudée doit être mise à la terre, le faire directement

avec un câble distinct.

l Ne pas toucher l’électrode quand on est en contact avec la pièce,

la terre ou une électrode provenant d’une autre machine.

l Ne pas toucher des porte électrodes connectés à deux machines

en même temps à cause de la présence d’une tension à vide

doublée.

l N’utiliser qu’un matériel en bon état. Réparer ou remplacer sur-le-

champ les pièces endommagées. Entretenir l’appareil conformé-

ment à ce manuel.

OM-243477 Page 6

l Porter un harnais de sécurité si l’on doit travailler au-dessus du

sol.

l S’assurer que tous les panneaux et couvercles sont correctement

en place.

l Fixer le câble de retour de façon à obtenir un bon contact métal-

métal avec la pièce à souder ou la table de travail, le plus près

possible de la soudure.

l Isoler la pince de masse quand pas mis à la pièce pour éviter le

contact avec tout objet métallique.

l Ne pas raccorder plus d’une électrode ou plus d’un câble de

masse à une même borne de sortie de soudage. Débrancher le

câble pour le procédé non utilisé.

l Utiliser une protection différentielle lors de l’utilisation d’un équipe-

ment auxiliaire dans des endroits humides ou mouillés.

Il reste une TENSION DC NON NÉGLIGEABLE dans les sources

de soudage onduleur UNE FOIS l’alimentation coupée.

l Éteignez l’unité, débranchez le courant électrique, et déchargez

les condensateurs d’alimentation selon les instructions indiquées

dans le manuel avant de toucher les pièces.

LES PIÈCES CHAUDES peuvent

provoquer des brûlures.

l Ne pas toucher à mains nues les parties chaudes.

l Prévoir une période de refroidissement avant de

travailler à l’équipement.

l Ne pas toucher aux pièces chaudes, utiliser les outils recomman-

dés et porter des gants de soudage et des vêtements épais pour

éviter les brûlures.

DES PIECES DE METAL ou DES

SALETES peuvent provoquer des

blessures dans les yeux.

l Le soudage, l’écaillement, le passage de la pièce

à la brosse en fil de fer, et le meulage génèrent

des étincelles et des particules métalliques volantes. Pendant la

période de refroidissement des soudures, elles risquent de proje-

ter du laitier.

l Porter des lunettes de sécurité avec écrans latéraux ou un écran

facial.

LES FUMÉES ET LES GAZ peuvent

être dangereux.

Le soudage génère des fumées et des gaz. Leur

inhalation peut être dangereux pour votre santé.

l Eloigner votre tête des fumées. Ne pas respirer les fumées.

l À l’intérieur, ventiler la zone et/ou utiliser une ventilation forcée au

niveau de l’arc pour l’évacuation des fumées et des gaz de sou-

dage. Pour déterminer la bonne ventilation, il est recommandé de

procéder à un prélèvement pour la composition et la quantité de

fumées et de gaz auxquelles est exposé le personnel.

l Si la ventilation est médiocre, porter un respirateur anti-vapeurs

approuvé.

l Lire et comprendre les fiches de données de sécurité et les ins-

tructions du fabricant concernant les adhésifs, les revêtements,

les nettoyants, les consommables, les produits de refroidisse-

ment, les dégraisseurs, les flux et les métaux.

l Travailler dans un espace fermé seulement s’il est bien ventilé ou

en portant un respirateur à alimentation d’air. Demander toujours

à un surveillant dûment formé de se tenir à proximité. Des fumées

et des gaz de soudage peuvent déplacer l’air et abaisser le niveau

d’oxygène provoquant des blessures ou des accidents mortels.

S’assurer que l’air de respiration ne présente aucun danger.

l Ne pas souder dans des endroits situés à proximité d’opérations

de dégraissage, de nettoyage ou de pulvérisation. La chaleur et

les rayons de l’arc peuvent réagir en présence de vapeurs et for-

mer des gaz hautement toxiques et irritants.

l Ne pas souder des métaux munis d’un revêtement, tels que l’acier

galvanisé, plaqué en plomb ou au cadmium à moins que le revête-

ment n’ait été enlevé dans la zone de soudure, que l’endroit soit

bien ventilé, et en portant un respirateur à alimentation d’air. Les

revêtements et tous les métaux renfermant ces éléments peuvent

dégager des fumées toxiques en cas de soudage.

LES ACCUMULATIONS DE GAZ

risquent de provoquer des blessures

ou même la mort.

l Fermer l’alimentation du gaz comprimé en cas de

non utilisation.

l Veiller toujours à bien aérer les espaces confinés ou se servir d’un

respirateur d’adduction d’air homologué.

LES RAYONS DE L’ARC peuvent

provoquer des brûlures dans les

yeux et sur la peau.

Le rayonnement de l’arc du procédé de soudage

génère des rayons visibles et invisibles intenses

(ultraviolets et infrarouges) susceptibles de provoquer des brûlures

dans les yeux et sur la peau. Des étincelles sont projetées pendant le

soudage.

l Porter un casque de soudage approuvé muni de verres filtrants

approprié pour protéger visage et yeux pour protéger votre visage

et vos yeux pendant le soudage ou pour regarder (voir ANSI

Z49.1 et Z87.1 énuméré dans les normes de sécurité).

l Porter des lunettes de sécurité avec écrans latéraux même sous

votre casque.

l Avoir recours à des écrans protecteurs ou à des rideaux pour pro-

téger les autres contre les rayonnements les éblouissements et

les étincelles ; prévenir toute personne sur les lieux de ne pas re-

garder l’arc.

l Porter un équipement de protection pour le corps fait d’un maté-

riau résistant et ignifuge (cuir, coton robuste, laine). La protection

du corps comporte des vêtements sans huile comme par ex. des

gants de cuir, une chemise solide, des pantalons sans revers, des

chaussures hautes et une casquette.

LE SOUDAGE peut provoquer un

incendie ou une explosion.

Le soudage effectué sur des conteneurs fermés

tels que des réservoirs, tambours ou des conduites

peut provoquer leur éclatement. Des étincelles

peuvent être projetées de l’arc de soudure. La projection d’étincelles,

des pièces chaudes et des équipements chauds peut provoquer des

incendies et des brûlures. Le contact accidentel de l’électrode avec

des objets métalliques peut provoquer des étincelles, une explosion,

un surchauffement ou un incendie. Avant de commencer le soudage,

vérifier et s’assurer que l’endroit ne présente pas de danger.

l Déplacer toutes les substances inflammables à une distance de

10,7 m de l’arc de soudage. En cas d’impossibilité les recouvrir

soigneusement avec des protections homologués.

l Ne pas souder dans un endroit là où des étincelles peuvent tom-

ber sur des substances inflammables.

l Se protéger et d’autres personnes de la projection d’étincelles et

de métal chaud.

l Des étincelles et des matériaux chauds du soudage peuvent faci-

lement passer dans d’autres zones en traversant de petites fissu-

res et des ouvertures.

l Surveiller tout déclenchement d’incendie et tenir un extincteur à

proximité.

l Le soudage effectué sur un plafond, plancher, paroi ou séparation

peut déclencher un incendie de l’autre côté.

OM-243477 Page 7

l Ne pas couper ou souder des jantes ou des roues. Les pneus peu-

vent exploser s’ils sont chauffés. Les jantes et les roues réparées

peuvent défaillir. Voir OSHA 29 CFR 1910.177 énuméré dans les

normes de sécurité.

l Ne pas effectuer le soudage sur des conteneurs fermés tels que

gaz ou émanations inflammables (vapeur d’essence, par

exemple).

l Brancher le câble de masse sur la pièce le plus près possible de

la zone de soudage pour éviter le transport du courant sur une lon-

gue distance par des chemins inconnus éventuels en provoquant

des risques d’électrocution, d’étincelles et d’incendie.

l Ne pas utiliser le poste de soudage pour dégeler des conduites

gelées.

l En cas de non utilisation, enlever la baguette d’électrode du porte-

électrode ou couper le fil à la pointe de contact.

l Porter un équipement de protection pour le corps fait d’un maté-

riau résistant et ignifuge (cuir, coton robuste, laine). La protection

du corps comporte des vêtements sans huile comme par ex. des

gants de cuir, une chemise solide, des pantalons sans revers, des

chaussures hautes et une casquette.

l Avant de souder, retirer toute substance combustible de vos po-

ches telles qu’un allumeur au butane ou des allumettes.

l Une fois le travail achevé, assurez-vous qu’il ne reste aucune

trace d’étincelles incandescentes ni de flammes.

l Utiliser exclusivement des fusibles ou coupe-circuits appropriés.

Ne pas augmenter leur puissance; ne pas les ponter.

l Suivre les recommandations dans OSHA 1910.252 (a) (2) (iv) et

NFPA 51B pour les travaux à chaud et avoir de la surveillance et

un extincteur à proximité.

2-6. Informations relatives aux CEM

Le courant électrique qui traverse tout conducteur génère des

champs électromagnétiques (CEM) à certains endroits. Le courant is-

su d’un soudage à l’arc (et de procédés connexes, y compris le sou-

dage par points, le gougeage, le découpage plasma et les opérations

de chauffage par induction) crée un champ électromagnétique (CEM)

autour du circuit de soudage. Les champs électromagnétiques pro-

duits peuvent causer interférence à certains implants médicaux,

p. ex. les stimulateurs cardiaques. Des mesures de protection pour

les porteurs d’implants médicaux doivent être prises: par exemple,

des restrictions d’accès pour les passants ou une évaluation indivi-

duelle des risques pour les soudeurs. Tous les soudeurs doivent ap-

pliquer les procédures suivantes pour minimiser l’exposition aux CEM

provenant du circuit de soudage:

1. Rassembler les câbles en les torsadant ou en les attachant avec

du ruban adhésif ou avec une housse.

2. Ne pas se tenir au milieu des câbles de soudage. Disposer les câ-

bles d’un côté et à distance de l’opérateur.

3. Ne pas courber et ne pas entourer les câbles autour de votre

corps.

4. Maintenir la tête et le torse aussi loin que possible du matériel du

circuit de soudage.

5. Connecter la pince sur la pièce aussi près que possible de la

soudure.

6. Ne pas travailler à proximité d’une source de soudage, ni s’asseoir

ou se pencher dessus.

7. Ne pas souder tout en portant la source de soudage ou le

dévidoir.

En ce qui concerne les implants médicaux :

Les porteurs d’implants doivent d’abord consulter leur médecin avant

de s’approcher des opérations de soudage à l’arc, de soudage par

points, de gougeage, du coupage plasma ou de chauffage par induc-

tion. Si le médecin approuve, il est recommandé de suivre les procé-

dures précédentes.

SECTION 4 – SPECIFICATIONS

4-1. Features And Benefits

Auto-Line

™

Power Management Technology is circuitry that automatically adapts the power source to the primary voltage being applied (see

Section 5-8).

LVC

™

Line Voltage Compensation is circuitry that keeps the power source output constant regardless of input power fluctuation.

Wind Tunnel Technology

™

circulates air over components that require cooling, not over electronic circuitry, which reduces contaminants and im-

proves reliability in harsh welding environments.

Fan-On-Demand

™

cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled through the

machine.

Thermal Overload Protection automatically shuts down the unit, only when necessary to prevent damage to internal components if the duty

cycle is exceeded or air flow and cooling are restricted (see Section 4-8).

Auto Remote Sense enables the unit to automatically sense the connection of a remote control. Operation of the remote control is dependent

on the Mode Switch Setting (see Section 6-2).

Lift-Arc

™

TIG starts provide a contamination free weld without the use of high frequency in the Lift-Arc TIG Welding Mode (see Section 7-3).

Synergic Pulsed MIG Operation allows single knob control of the arc. As wirefeed speed is increased or decreased, the pulse parameters in-

crease or decrease matching the power output to the wire speed (see Section 6-3).

4-2. Arc Controls

DIG control allows the arc characteristics, soft versus stiff, to be changed for specific applications and electrodes in CC and Stick Welding Modes

(see Sections 9-2 and 9-3).

Programmable Hot Start allows the start amperage and time to be changed for CC and Stick Welding Modes (see Sections 9-2 and 9-3).

Inductance influences the arc stiffness, bead width and appearance, and puddle fluidity in MIG and V-Sense Feeder Welding Modes (see Sec-

tions 8-2 and 8-8).

SharpArc

™

optimizes the size and shape of the arc cone, bead width and appearance, and puddle fluidity in Pulsed MIG Welding Mode(see Sec-

tion 8-4).

4-3. Software Licensing Agreement

The End User License Agreement and any third-party notices and terms and conditions pertaining to third-party software can be found at

https://www.millerwelds.com/eula and are incorporated by reference herein.

4-4. Information About Default Weld Parameters And Settings

NOTICE – Each welding application is unique. Although certain Miller Electric products are designed to determine and default to certain typical

welding parameters and settings based upon specific and relatively limited application variables input by the end user, such default settings are

for reference purposes only; and final weld results can be affected by other variables and application-specific circumstances. The appropriate-

ness of all parameters and settings should be evaluated and modified by the end user as necessary based upon application-specific require-

ments. The end user is solely responsible for selection and coordination of appropriate equipment, adoption or adjustment of default weld

parameters and settings, and ultimate quality and durability of all resultant welds. Miller Electric expressly disclaims any and all implied warran-

ties including any implied warranty of fitness for a particular purpose.

4-5. Unit Specifications

Do not use information in unit specifications table to determine electrical service requirements. See Sections 5-7 thru 5-8 for information on
