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 small
internal clearance or slight preload 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 40% power
when using the small yoke or 60% power when using the sliding yoke.
• When using the small yoke, never exceed 60% power.

Safety features

The IH 210 is equipped with the following safety features:
• Main switch with overcurrent circuit breaker
• Automatic overheating protection
• Automatic current control
• In the TEMP MODE the heater will switch off if the temperature probe
does not register a temperature increase of 1° every 15 seconds.
To increase the interval to 30 seconds, press MODE and DOWN at
the same time.
