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 may 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. 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.

ergize weld control; welding wire is not

energized; shielding gas does not flow.

Secure plug from gun/feeder trigger cord into 10-socket receptacle on weld control (see Sections 5-4 and

5-5).

Wire feeds, shielding gas flows, bu

welding wire is not energized.

Secure control cable leads in weld control (see weld control Owner’s Manual).

See Troubleshooting section in welding power source Owner’s Manual.

Wire feeds erratically. Check and correct drive roll pressure (see Section 5-7).
