An induction heater has an induction coil (26) for heating a metallic substance (4, Fig.2, not shown) hidden by a membrane (2, Fig.2) the metallic substance being coated with a heat activated adhesive on its side adjacent the membrane (2). The heater has four location sensor coils (36) for detecting the position of the hidden metallic substance and means to facilitate the placement of the induction coil (26) over the hidden metallic substance (4), based on information from the sensors. Once the induction coil (26) is over the metallic substance (4) it is used to heat the adhesive thereby adhering the metallic substance (4) to the membrane (2). The sensors (36) are adjacent the inductor coil (26) and are insulated therefrom by an air gap (38). The membrane may be, e.g., a roof covering. |
