Claim Text:
1. A method of removing a fastener component that is adhesively bonded to a substrate, comprising: (a) providing a tool with pulsed induction heating and a selection of coils that are mountable to the tool, each of the coils having a loop with a different inner diameter; (b) selecting one of the coils in which the inner diameter of the loop is larger than a footprint of the fastener component; (c) inserting leads of the selected coil into the tool and positioning the loop of the selected coil around the fastener component, adjacent to a surface of the substrate; (d) pulsing the tool to heat the fastener component, substrate and adhesive, wherein pulsing the tool comprises closing a switch, which while the switch is closed, causes the tool to provide a plurality of pulses in which inductive electrical power is supplied to the selected coil, each of the pulses being followed by a wait period in which inductive electrical power is not supplied to the selected coil; (e) detecting a temperature of the substrate; (f) repeating steps (d) and (e) until the substrate reaches a target temperature and the adhesive is softened; and then (g) scraping the component and adhesive from the substrate.
