1-6.EMF Information
Considerations About Induction Heating And The Effects Of Low Frequency Electric And Magnetic Fields
The following is a quotation from the General Conclusions Section of the
U.S. Congress, Office of Technology Assessment, Biological Effects ofPower Frequency Electric & Magnetic Fields − Background Paper, OTA-
BP-E-53 (Washington, DC: U.S. Government Printing Office, May
1989): “. . . there is now a very large volume of scientific findings based
on experiments at the cellular level and from studies with animals and
people which clearly establish that low frequency magnetic fields can interact with, and produce changes in, biological systems. While most of
this work is of very high quality, the results are complex. Current scientific understanding does not yet allow us to interpret the evidence in a
single coherent framework. Even more frustrating, it does not yet allow
us to draw definite conclusions about questions of possible risk or to offer clear science-based advice on strategies to minimize or avoid
potential risks.”
To reduce magnetic fields in the workplace, use the following procedures:
1. Arrange output cable to one side and away from the operator.
2. Do not coil or drape output cable around the body.
3. Keep power source and cable as far away from the operator as
practical.
About Pacemakers:
Pacemaker wearers consult your doctor before welding or going near
welding or induction heating operations. If cleared by your doctor, then
following the above procedures is recommended.

Le texte suivant est extrait des conclusions générales Département
du Congrès U.S., Office of Technology Assessment, Effets
biologiques des champs magnétiques et électriques basse
fréquence − Background Paper, OTA-BP-E-53 (Washington, DC:
U.S. Government Printing Office, May 1989): “. . . on dispose
maintenant d’importantes découvertes scientifiques reposant sur
des expériences effectuées dans le domaine cellulaire et des études
réalisées sur des animaux et des personnes qui démontrent
clairement que des champs magnétiques basse fréquence peuvent
avoir une interaction et produire des changements dans les
systèmes biologiques. Alors que la plus grande partie de cet ouvrage
est d’une très grande qualité, les résultats sont complexes. La
compréhension scientifique courante ne nous permet pas encore
d’interpréter la preuve fournie dans un seul ouvrage cohérent. Il est
encore plus frustrant de ne pas pouvoir tirer des conclusions
définitives en ce qui concerne les problèmes de risque possible ou de
proposer des recommandations scientifiques claires pour des
stratégies à suivre en vue de minimiser ou de prévenir des risques
potentiels.”
Pour réduire les champs magnétiques sur le poste de travail,
appliquer les procédures suivantes :
4. Disposer le câble de sortie d’un côté à distance de l’opérateur
5. Ne pas enrouler ou draper le câble électrique autour du corps.
6. Placer la source de courant et le câble le plus loin possible de
l’opérateur.

Reference: 2005 National Electrical Code (NEC) (including article 630)
1 Choose a circuit breaker with time-current curves comparable to a Time Delay Fuse.
2 Time-Delay fuses are UL class RK5 .
3 Normal Operating (general purpose - no intentional delay) fuses are UL class K5 (up to and including 60 amp), and UL class H ( 65 amp and above).
4 Conductor data in this section specifies conductor size (excluding flexible cord or cable) between the panelboard and the equipment per NEC Table
310.16. If a flexible cord or cable is used, minimum conductor size may increase. See NEC Table 400.5(A) for flexible cord and cable requirements.
Y Caution: Failure to follow these fuse and circuit breaker recommendations could create an electric shock or fire hazard. These
recommendations are for a dedicated branch circuit that applies to the rated output and duty cycle of the welding power source.
