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

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.
