1-5. EMF Information
Electric current flowing through any conductor causes localized electric
and magnetic fields (EMF). The current from arc welding (and allied pro-
cesses including spot welding, gouging, plasma arc cutting, and induc-
tion 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 individu-
al risk assessment for welders. All welders should use the following pro-
cedures 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.

2-5. 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. Le courant
issu d’un soudage à l’arc (et de procédés connexes, y compris le
soudage 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 produits 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:
Limiter par exemple tout accès aux passants ou procéder à une
évaluation des risques individuels 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
induction. Si le médecin approuve, il est recommandé de suivre les pro-
cédures précédentes.

5/3/1 WARRANTY applies to all Hobart welding equipment, plasma cutters and spot welders with a

This limited warranty supersedes all previous Hobart warranties and is exclusive with
no other guarantees or warranties expressed or implied.
Hobart products are serviced by Hobart or Miller Authorized Service Agencies.
LIMITED WARRANTY − Subject to the terms and conditions
below, Miller Electric Mfg. LLC, dba Hobart Welding Products,
Appleton, Wisconsin, warrants to its original retail purchaser that
new Hobart equipment sold after the effective date of this limited

Within the warranty periods listed below, Hobart/Miller will repair or
replace any warranted parts or components that fail due to such
defects in material or workmanship. Hobart/Miller must be notified
in writing within thirty (30) days of such defect or failure, at which
time Hobart/Miller will provide instructions on the warranty claim
procedures to be followed. If notification is submitted as an online
warranty claim, the claim must include a detailed description of the
fault and the troubleshooting steps taken to identify failed
components and the cause of their failure.
Hobart/Miller shall honor warranty claims on warranted equipment
listed below in the event of such a failure within the warranty time
periods. All warranty time periods start on the delivery date of the
equipment to the original retail purchaser, and not to exceed twelve
months after the equipment is shipped to a North American

International distributor.

INDUSTRIAL USERS TRAINED AND EXPERIENCED IN THE USE

The exclusive remedies for warranty claims are, at

approved in writing by Hobart/Miller, (3) the pre-approved cost of
repair or replacement at an authorized Hobart/Miller service
station; or (4) payment of or credit for the purchase price (less
reasonable depreciation based upon use). Products may not be

shipment shall be at customer’s risk and expense.
The above remedies are F.O.B. Appleton, WI, or Hobart’s/Miller’s
authorized service facility. Transportation and freight are the
customer’s responsibility. TO THE EXTENT PERMITTED BY
LAW, THE REMEDIES HEREIN ARE THE SOLE AND
EXCLUSIVE REMEDIES REGARDLESS OF THE LEGAL
THEORY. IN NO EVENT SHALL HOBART/MILLER BE LIABLE
FOR DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF PROFIT)
REGARDLESS OF THE LEGAL THEORY. ANY WARRANTY
NOT PROVIDED HEREIN AND ANY IMPLIED WARRANTY,
GUARANTY, OR REPRESENTATION, INCLUDING ANY
IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS
FOR PARTICULAR PURPOSE, ARE EXCLUDED AND
DISCLAIMED BY HOBART/MILLER.
Some US states do not allow limiting the duration of an implied
warranty or the exclusion of certain damages, so the above
limitations may not apply to you. This warranty provides specific
legal rights, and other rights may be available depending on your
state. In Canada, some provinces provide additional warranties or
remedies, and to the extent the law prohibits their waiver, the
limitations set out above may not apply. This Limited Warranty
provides specific legal rights, and other rights may be available,
but may vary by province.
