Abstract

A tweezer-like heater structure includes a pair of arms that can be pivoted towards one another and a pair of legs having ferromagnetic temperature self regulating Curie point heaters at the ends of the legs, the legs being removably connectable to electrical connectors located in the arms whereby current is supplied to coils that energize the heaters. Heaters of different temperatures are provided by choosing heaters with ferromagnetic materials having different Curie temperatures. The structure is used as a soldering iron by inserting a heater with a proper shape in one arm and short circuitry the connector in the other arm.
