Keep in mind that heat is generated directly at or underneath the
inductor cable. This, together with shape and construction of the
workpiece might be of influence on where and how fast heat in
the workpiece is generated.
A thinner part of the workpiece will heat much faster than a
thicker part.
When the inductor cable is wrapped directly over a foreign part of
the workpiece such as bolts, nuts or metal nametags this might
cause that these parts also will be heated much faster than the
rest of the workpiece. This can lead to damage of the inductor.
Avoid such situations as much as possible.
In the example below for instance the red area will heat much
faster than the rest of the coupling because there is less mass.
It is best to put temperature probe in this area (in the immediate
vicinity of a turn/winding) to avoid damage of the inductor.
IMPORTANT!
When using a flexible inductor, always put the
temperature sensor in the immediate vicinity of a
turn / winding. This is where the heat is developed
in the workpiece first. Above that keep in mind
that thinner parts of a workpiece heat much
faster so this is also a criteria where the magnetic
temperature sensor should be put.
Examples of correct sensor positions.
When an inductor is used in a wrong way its sheath (isolation)
can get damaged/burned.
For each use inductors have to be inspected for damage!
Inductors with damaged sheath / isolation should be replaced.
NOTE!
Do not use damaged inductors!

6.4 Operation in temperature mode
As soon as the heater is connected in accordance with the
instructions on chapter 5 and the power switches have been
switched on, the touch screen briefly lights up showing the
welcome screen. This is followed by the main menu.
In this menu, select temperature mode by briefly touching the
"Temp. mode" bar. The screen now jumps to the "Temperature
mode" screen.
NOTE!
If using the Delta T option, the screen will show 2 temperatures, A
and B. see chapter 6.9.
This screen displays the settings (programme) related to the
connected (fixed) inductor. The generator recognises the inductor
using the recognition option. The associated settings are
programmed and are now shown on the display. The programme
being followed is displayed at the bottom of the screen:
programme 1, 2, 3 or STD. The programmes 1, 2 and 3 can be
changed in the settings menu if required. To do this, follow the
instructions in the section in the settings menu.
The required temperature can be changed if necessary by
pressing "Enter".
In order to set the desired temperature, press the "enter" tab.
The temperature is shown in a black bar. At the bottom of the
screen, 2 tabs with arrows appear. Use these tabs to set the
desired temperature. Once the change has been made, press
"enter" to validate the new setting.
