Abstract: A soldering iron hand piece that may be used for both a soldering tip and a soldering cartridge, allowing the same hand piece to be used for both a soldering tip and a soldering cartridge.

Abstract: A pair of soldering tweezers having a first arm having a distal end that is adjustably positionable in a direction parallel to its central longitudinal axis and a second arm having a distal end that is adjustably positionable in a direction perpendicular to its central longitudinal axis. The tweezers also include a biasing mechanism configured to urge the distal ends of the first and second arms apart.

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.

Abstract: A desoldering tool has a removable heater cartridge and a base unit having an assembly interior including a solder collection chamber and a removable vacuum source for developing a vacuum in and above the chamber and a removable porous solder retention pad located between the vacuum source and the solder collection chamber, the cartridge having a temperature self-regulating heater therein, a tail pipe extending from a hollow tip of the cartridge to a position above the solder collection chamber, and a vacuum seal between the cartridge and the base unit to maintain the vacuum and reduce transfer of heat from the tip. The tool is readily converted to a soldering iron or a hot air gun.

Abstract: A desoldering tool has a removable cartridge and a base unit having an assembly interior including a solder collection chamber and a removable vacuum source for developing a vacuum in the bottom of the chamber under a removable porous solder retention pad, the cartridge having a temperature self-regulating heater therein and a tail pipe extending from a tip of the cartridge to a position above the solder collection chamber, and a vacuum seal between the cartridge and the base unit to maintain the vacuum and reduce transfer of heat from the tip.
