Abstract
A desirable relative positional relationship between an inductor and a workpiece to be heated is detected by an electrical circuit which is closed upon relative movement of the inductor and workpiece to the desired relative position. The detecting circuit includes a contact positioned relative to the inductor and engagable with the workpiece upon relative movement of the inductor and workpiece in one direction. Upon such engagement a circuit is completed to stop relative movement in the one direction.
