Power level selection

When heating bearings with an induction heater, most of the heat will be
generated in the inner bearing race. The heat will then be transferred through the
bearing. It is therefore important that bearings with reduced internal clearance are
heated slowly. Slow heating ensures that the bearing expands evenly, thereby
preventing damage to the bearing.
The shape, weight, size, and internal clearances all affect the amount of time
required to heat a bearing. The large variety of bearing types precludes the
possibility of providing a specific power level setting for each type. Instead, the
following guidelines are provided:
• "For sensitive bearings (including bearings with C1 or C2 internal clearance) or
bearings with brass cages, do not exceed 50% power.
• "When using the small yoke, never exceed 50% power.

SAFETY FEATURES

The TIH 100m is equipped with the following safety features:
• "Automatic overheating protection
• "Automatic current control
• "Over-current circuit breaker.
• "In the TEMP MODE the heater will switch off if the temperature probe does
not register a temperature increase of 1 °C (1.8 °F) every 15 seconds
(0.25 minute). To increase the interval to 30 seconds (0.50 minute), press
MODE and DOWN at the same time.
