Power Level Selection; Safety Features - SKF TIH L 33/MB Bedienungsanleitung

5.8 Power level selection

When heating workpieces with an induction heater, the most of the heat will be generated
in the bore and then transferred through the workpiece. Slow heating ensures that
the workpiece expands more evenly, thereby preventing damage. The large variety of
workpieces precudes the possibility of providing a speciic power level setting for each type.
Instead, the following guidelines are provided:
• For sensitive workpieces, with a combination of different materials (such as
aluminum, brass), do not exceed 50% power.
• When using accessory smaller yoke, never exceed 50% power.
