ABSTRACT:
An apparatus for heating a metal surface to remove a nonferrous thermosetting resin coating bonded to the metal surface. The apparatus uses a power supply device for providing an approximately 75-100 kW signal at approximately 10-40 kHz to the apparatus. A coil assembly device is coupled to the power supply device for producing a high frequency inductive field which will penetrate through the nonferrous thermosetting resin coating with virtually no attenuation and will induce an eddy current of sufficient power in the underlying metal substrate to rapidly heat the interface to a sufficient temperature to immediately destroy the interface bond between the nonferrous thermosetting coating and the metal substrate.
