Safety features

The heater will switch off automatically if the ambient temperature exceeds 70ºC (158ºF).

When using the temperature mode, the heater will switch off automatically if the rate of
temperature rise is too low.

On models equipped with a swing arm, the arm can be fixed in the open position.
An induction heater works due a magnetic field. In the table below are there are some measured
values of the flux density in milliTesla (mT). These values are measured in different radii and heights
around the heater. These measurements can be used as a guide in conforming to local regulations
regarding the maximum time exposure of people to magnetic fields.
The values below are only valid for this combination of bearing type and yoke bar.
Different configurations may give different values. Due to the large variety of bearing types in
combination with the different yoke bars it is impossible for us to give every possible value.

Heights are measured from the bottom of the heater. To determine where the field is exactly in relation
to the floor, the distance from the bottom of the heater to the floor should be added on to the values
mentioned in the table. (e.g. the height of a workbench).
WARNING!

We advise a safety distance of at least 1 meter for people.
CAUTION! The machine works through an induction field. Bear in mind that this can influence
electronic equipment, e.g. watches, magnetic charts etc.
