A dispenser heats and dispenses a melted material through an orifice. A pusher (24) is slidably received within an interior of a cylindrical body (12) of the dispenser and is movable relative to the forward end of the cylindrical body (12). The pusher (24) is made up of an internally threaded cylinder that receives a driver screw and engages a stick of meltable material. The pusher (24) is used to advance the meltable material toward the forward end of the body (12). The pusher (24) retracts when the meltable material is exhausted. An induction heated system has a suspector plate with apertures that lead to the nozzle. In use, the motor (42) automatically retracts the pusher (24) a slight increment when the motor (42) is turned off, which relieves static pressure on the elastic zone of the stick. A PC board (66) has a control circuit to control the advancing and retracting of the pusher (24) and for controlling the temperature of the inductor by regulating the flow of power to the inductor.
