5. Method of operation

Bessey cone heaters work by means of a heating element which in turn heats the aluminium
cone from the inside. Once this cone is hot, heat is directly transferred to the work piece
through a combination of conduction and radiant heat.

6. The thermostat


Some cone heater models are equipped with a thermostatic probe that automatically
shuts of the heater. If provided, the thermostat probe is permanently attached to the
heater.
(model GSS-CB)

The thermostat control is set to a fixed temperature. It will switch off the heater at
workpiece temperature of 110°C (230°F) and will switch on the heater again at workpiece
temperatures of 95°C (203°F) and below.

Make sure that the thermostat and the workpiece are properly clean.

Always place the thermostat probe as close as possible to the bore, which is clean and
free of grease.

Do not use the thermostat probe at temperatures of 130°C (265°F) and above. The probe
will get damaged. Do not put the thermostat directly on the cone of the heater.

Some bearings or workpieces may be too small for use with the thermostat. In those
cases use an external thermometer or phase change marker to monitor the
temperature.

Do not leave unattended!

Note: Cone heaters provided with a thermostat probe will operate
without the thermostat being put on the workpiece. Simply leave the
probe on bench top beside the heater.
