fer clear science-based advice on strategies to minimize or avoid  
potentialrisks.”  
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  
peoplewhich clearly establish that low frequency magnetic fields can in-  
teract with, and produce changes in, biological systems. While most of  
this work is of very high quality, the results are complex. Current scientif-  
ic 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 of-  
To reduce magnetic fields in the workplace, use the following proce-  
dures:  
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 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.

Considérations relatives au chauffage à induction et aux effets des champs  
électriques et magnétiques basse fréquence.  
claires pour des stratégies à suivre en vue de minimiser ou de prévenir  
des risques potentiels.”  
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 scienti-  
fique 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  
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 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 procédures précé-  
dentes.

4-12. Secondary Insulation Protection  
Secondary insulation 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(s) must  
be connected between the  
workpiece and power source to  
provide proper secondary insula-  
tion protection from a short in the  
output circuit.  
For single output, only one  
ground lead is required. For dual  
output , use both ground leads.

4-14. Locating Thermocouples  
Thermocouplelocation is one of the most critical steps in the Heat Treatment Operation.  
Thermocouples shall be located as follows to provide a survey of heating uniformly and enable time and temperature control:  
1.  
Locate thermocouples to ensure that the full area of the heat band is monitored.  
S
S
S
The code normally specifies the number of thermocouples to be used based on the pipe diameter.  
The control thermocouple is placed in the plane of the weld (center of the heat zone).  
The control thermocouple is placed at the top of the pipe in a standard pipe joint configuration. In other  
applications, the thermocouple should be located in the hottest portion of the weldment to be stress relieved.  
2.  
Consider all nozzles and other welded attachments that cause potential heat sinks through metal mass or cold spots due to heat convection or  
conduction, and have additional thermocouples applied.  
3.  
4.  
5.  
6.  
Attach a spare thermocouple beside control thermocouples.  
Attach thermocouples to ensure uniformity of temperature in both thin and thick workpieces.  
Physically inspect all thermocouples for continuity and mark them by an identification number corresponding to the recorder channel.  
Match the drawings of the workpiece indicating the numerous thermocouple locations, controlling thermocouple locations, etc. to weld identifi-  
cation information.  
7.  
The system is equipped with 3-pin thermocouple connections at the front of the unit. Six thermocouples can be attached to the power source.  
S
The system is equipped with 3-pin connectors to accommodate shielded extension cables. The shielded  
cables protect from electrical interference.  
8.  
Type K thermocouple wire has a positive and negative wire. The positive wire is marked as solid yellow or striped yellow. The connector screw  
terminals are marked positive and negative. Be sure to attach the wire to the connector with proper polarity.

The following describes the thermocouple routing from work to power source.  
S
Type K thermocouple wire (two wire) is attached directly to the workpiece using a  
Thermocouple Attachment Unit (see next section for information on attaching thermocouples).  
S

4-15. Attaching Welded Thermocouples  
. Do NOT weld thermocouples while connected to power source.  
1.  
Attach thermocouples using a portable Thermocouple Attachment Unit (TAU). This unit spot welds thermocouple wire directly to the  
workpiece. This method of thermocouple attachment ensures accurate temperature measurement.  
2.  
3.  
4.  
5.  
6.  
Clean (file or grind) any loose scale or rust from the workpiece at the places where the wires will be attached.  
Clean the location for the lead magnet to minimize resistance. Place the magnet as near to the thermocouple positions as possible.  
Strip 1/4 inch of insulation from the thermocouple wires.  
Set the output variable control of the TAU to about eighty percent (80%).  
Grasp one of the stripped wires with the tip of the jaws of the application pliers.  
. Don’t touch both wires of the thermocouple to the pliers at the same time when energizing the Thermocouple Attachment Unit. This will cause  
the thermocouple wire to fuse to the pliers, rather than the workpiece.  
7.  
Press the end of the wire to the workpiece at ninety degrees to the surface, and maintain a firm pressure. Make sure the Thermocouple Attach-  
ment Unit is charged and wait for the ready light to glow.  
8.  
9.  
Press discharge button, and the wire should weld to the workpiece. There will be a sharp crack and a slight arc flash.  
Repeat the process with the other wire, placing it approximately 1/4 inch away from the first wire. Attach a spare thermocouple, and support  
both thermocouples approximately 18 inches back from the connection with a band or fiber tape.  
10.  
Carefully bend the wire over at right angles. This brings the thermocouple wires out along or parallel to the workpiece. It also tests the strength  
of the weld. If the weld shows signs of breaking, remove the wire, restrip the end, and repeat the process.

4-16. Using Contact Thermocouples  
The welded thermocouples discussed previously can be used for preheating or stress relieving. As an alternative, in preheating applications, a contact  
temperaturesensor* can be used. This eliminates the need to weld thermocouples and the sensor can be moved during the preheat process to check  
temperaturesat other locations on the joint.  
. Removing the contact probe will display a short duration of heat drop on the temperature recorder, if used.  
The contact temperature sensor can be plugged into the thermocouple extension cable or a Type K 25 ft. armored extension cable* can be used. One of  
these extensions is required for each sensor.  
In preheating applications, the thermocouple must be placed under the induction coil. Temperatures at the weld joint can be checked with temperature  
sensitive crayons to verify the preheat temperature.  
Welded thermocouples are normally used in stress relieving applications due to their accuracy.

6-2. System Description  
The ProHeat 35 Induction Heating Power Source is designed to function either as an air-cooled system or a liquid-cooled system. Depending on the  
system type (either air-cooled or liquid-cooled), the power source is automatically configured to operate and provide an output appropriate for the type  
of connected heating device.  
A special identifier, embedded within the extension cable connector, provides the means for the power source to configure itself by recognizing the type  
of extension cable(s) attached to its output connectors.  
Designed to provide a single level of output (up to 35 kW), the ProHeat 35 power source has two panel mounted connectors that are connected in  
parallelto the power source output. This design allows the system to operate with either a single output extension cable or two output extension cables.  
If a single output extension cable is used, a protective plug (provided with the system) MUST be placed on the unused output connector or the system  
will not operate. If two output extension cables are used, they both MUST be of the same type (either both air-cooled or both liquid-cooled) or the system  
will not operate (in this case, the protective plug is not used). When two extension cables and heating devices are utilized on the system, the extension  
cable lengths and heating devices MUST be identical (see Section 4-7).  
The ProHeat 35 is intelligent to the point that it will automatically adjust output power levels if internal system operating parameters or internal tempera-

8-4. EMF Information  
ConsiderationsAbout Induction Heating And The Effects Of Low Fre-  
quency Electric And Magnetic Fields  
2. Arrange cables to one side and away from the operator.  
3. Do not coil or drape cables around your body.  
Induction heating current, as it flows through induction heating cables,  
will cause electromagnetic fields. There has been and still is some  
concern about such fields. However, after examining more than 500  
studies spanning 17 years of research, a special blue ribbon committee  
of the National Research Council concluded that: “The body of  
evidence, in the committee’s judgment, has not demonstrated that  
exposure to power-frequency electric and magnetic fields is a human-  
health hazard.” However, studies are still going forth and evidence  
continues to be examined. Until the final conclusions of the research are  
reached, you may wish to minimize your exposure to electromagnetic  
fields when using induction heating equipment.  
4. Keep induction heating power source and cables as far away  
from operator as practical.  
5. Connect work clamp to workpiece as close to the weld as  
possible.  
About Implanted Medical Devices:  
ImplantedMedical 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.  
To reduce magnetic fields in the workplace, use the following  
procedures:  
1. Keep cables close together by twisting or taping them, or using a  
cable cover.
