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 of
Power 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.

instructions du fabricant concernant les adhésifs, les métaux, les
consommables, les revêtements, les nettoyants et les
dégraisseurs.

5. Travailler dans un espace fermé seulement s’il est bien ventilé ou
en portant un respirateur. Demander toujours à un surveillant
dûment formé de se tenir à proximité. Des fumées et des gaz
provenant du chauffage peuvent déplacer l’air, abaisser le niveau
d’oxygène, et provoquer des lésions ou des accidents mortels.
S’assurer que l’air ambiant ne présente aucun danger.

6. Ne pas chauffer dans des endroits se trouvant à proximité
d’opérations de dégraissage, de nettoyage ou de pulvérisation. La
chaleur peut réagir en présence de vapeurs et former des gaz
hautement toxiques et irritants.

7. Ne pas chauffer des métaux munis d’un revêtement tels que l’acier
galvanisé, plaqué au plomb ou au cadmium, à moins que le
revêtement ne soit enlevé de la zone chauffée, que la zone soit
bien ventilée et, si nécessaire, en portant un respirateur. Les
revêtements et tous les métaux contenant ces éléments peuvent
dégager des fumées toxiques s’ils sont chauffés.

2-1. Dangers supplémentaires de mise en route, de fonctionnement et d’entretien

LA CHUTE DE MATERIEL peut provoquer
des blessures personnelles graves et en­dommager les équipements.

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.

En ce qui concerne les stimulateurs cardiaques

Les procédures ci-dessus concernent également les porteurs de
stimulateur cardiaque. Consulter votre médecin pour un complément
d’information.

SECTION 4 − OPERATION

4-1. Controls

1 Power Adjust Control
Use control to select power between the mini-

mum and maximum output of the power
source. The numbers around the control are in
kilowatts (kW).

2 Remote Power Control Switch
Use switch to select way of controlling unit out-

put.
For front panel control, place switch in Panel

position.

4

For remote control, place switch in Remote 14
position. Connect controller or pendant control
to Remote 14 receptacle (see Section 3-3).

The remote control functions as a slave to the
front panel Power Adjust control. For example,
if the front panel control is set to 12.5 kW and
the remote control is set to maximum, output
will be 12.5 kW. To obtain maximum output
from the unit using a remote control, the front
panel control must be set to maximum.

5-2. Overheating

Thermostats TP1, TP2, and TP3 protect the unit from damage due to overheating. If one or more of the heat sinks get
too hot, TP1, TP2, and/or TP3 opens and output stops. The fan keeps running to cool the heat sink(s). Wait several
minutes before trying to heat.

5-3. Automatic Shutdown Protection

This unit automatically shuts down upon sensing certain fault conditions, such as an out-of-range frequency condition,
short circuit load condition, or an open circuit (no load) condition. The unit also has automatic voltage limiting and
power ratio limiting, which limits the output power based on improper load impedance.

Ground fault protection circuitry
automatically shuts down the power
source output if a potentially
hazardous condition exists at the
heating device connected to the
power source (e.g. insulation has
broken down on a heating blanket
causing the conductor to come into
contact with the workpiece or a
heating coil touches the workpiece
causing a short in the output circuit).

The supplied ground lead must be
connected between the workpiece
and power source to provide
proper ground fault protection
from a short in the output circuit.
