摘要： An induction heater probe for use with stud mounted hot melt fasteners, the induction heater probe having an outer ferrite cup core portion and an inner hollow cylindrically shaped ferrite core portion with an aperture configured to receive the stud portion of a hot melt fastener. Induction windings surround the inner cylindrical core portion, the housing supporting the ferrite cup core portion including an adjustment screw for limiting the entry of the stud portion of the fastener into the core hole in the inner hollowed cylinder-shaped ferrite core portion of the pot core in the induction heater probe. The pot core ferrite material provides a low reluctance path for the magnetic field lines thereby shielding the stud portion of the hot melt fastener. A coupling coil surrounding the inner hollow cylindrical-shaped ferrite core portion is excited with 35 kHz energy for a period of about ten seconds thereby heating the fastener to approximately 600.degree. F. and melting the adhesive wafer portion of the stud mounted hot melt fastener.
