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. The

parts list will then help you to decide the

exact part you may need to fix the problem.

Warranty and service information for your

particular model are also provided.

Miller is the first welding

equipment manufacturer in

the U.S.A. to be registered to

the ISO 9001 Quality System

Standard.

Working as hard as you do

− every power source from

Miller is backed by the most

hassle-free warranty in the

business.

From Miller to You

proved air-supplied respirator.

MOVING PARTS can injure.

D Keep away from moving parts.

D Keep away from pinch points such as drive

rolls.

OM-248 984 Page 2

1-3. Proposition 65 Warnings

Welding or cutting equipment 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 Section 25249.5 et seq.)

This product contains chemicals, including lead, known to

the state of California to cause cancer, birth defects, or other

reproductive harm. Wash hands after use.

1-4. EMF Information

Electric current flowing through any conductor causes localized electric

and magnetic fields (EMF). Welding current creates an EMF field

around the welding circuit and welding equipment. EMF fields may inter-

fere with some medical implants, e.g. pacemakers. Protective meas-

ures for persons wearing medical implants have to be taken. For ex-

ample, access restrictions for passers−by or 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

welding 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 operations.

If cleared by your doctor, then following the above procedures is recom-

mended.

2-3. Proposition californienne 65 Avertissements

Les équipements de soudage et de coupage produisent des

fumées et des gaz qui contiennent des produits chimiques

dont l’État de Californie reconnaît qu’ils provoquent des

malformations congénitales et, dans certains cas, des

cancers. (Code de santé et de sécurité de Californie, chapitre

25249.5 et suivants)

Ce produit contient des éléments chimiques, dont le plomb,

reconnus par l’État de Californie pour leur caractère

cancérogène ainsi que provoquant des malformations

congénitales ou autres problèmes de procréation. Se laver

les mains après toute manipulation.

2-4. Informations relatives aux CEM

Le courant électrique qui traverse tout conducteur génère des champs

électromagnétiques (CEM) à certains endroits. Le courant de soudage

crée un CEM autour du circuit et du matériel de soudage. Les CEM

peuvent créer des interférences avec certains implants médicaux

comme des 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 individuelle

des risques pour les soudeurs. Tous les soudeurs doivent appliquer 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

câbles 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 procédu-

res précédentes.

SECTION 4 − INTRODUCTION

4-1. Important Information Regarding CE Products (Sold Within The EU)

! This equipment shall not be used by the general public as the EMF limits for the general public might be exceeded during welding.

This equipment is built in accordance with EN 60974−1 and is intended to be used only in an occupational environment (where the general public

access is prohibited or regulated in such a way as to be similar to occupational use) by an expert or an instructed person.

Wire feeders and ancillary equipment (such as torches, liquid cooling systems and arc striking and stabilizing devices) as part of the welding

circuit may not be a major contributor to the EMF. See the Owner’s Manuals for all components of the welding circuit for additional EMF exposure

information.

S The EMF assessment on this equipment was conducted at 0.5 meter.

S At a distance of 1 meter the EMF exposure values were less than 20% of the permissible values.
