ABSTRACT:
A heavy duty, pneumatic or manually operable hand-held desoldering tool. The tool comprises a hollow cylindrical large size barrel. There is further provided a hollow plunger loading cylinder and a plunger assembly removably mounted on the plunger loading cylinder. A plunger loading member is concentric with the plunger loading cylinder and includes a hollow cylinder slidable within the loading cylinder. A plunger loading guide is disposed concentric with and partially surrounding the plunger loading cylinder. Spring means are disposed in the plunger loading cylinder for urging the loading member outwardly and away from the loading cylinder. Trigger means are connected to the barrel and externally actuable for locking the plunger loading cylinder in its cocked, loaded position and for releasing it. Heavy duty spring means are disposed in the barrel and are retained between the plunger and the rear end of the barrel for rapidly returning the plunger rearwards upon release of the trigger means. This creates a vacuum and rapidly sucks in the ambient air for removing hot solder.
