ABSTRACT:
An improved solder removal device having means for automatically recocking the device after each use. A piston is slidably movable within a barrel and normally urged upward by a spring. The piston shaft projects upwardly from the piston and has a toothed area extending along one side which is engaged to a movable gear. The movable gear is mounted on a gear shaft which rotates in a bearing mounted to the shaft of a solenoid. A motor is mounted within the barrel and is operable, through suitable gearing to rotate the movable gear, thereby moving the piston shaft. The piston shaft also carries a pair of studs actuated by a trigger slide engageable with an arm of a switch to control actuation of the solenoid and motor. Upward movement of the piston creates a vacuum at the nozzle which removes excess molten solder. Electricity can be supplied from either a line source or a battery.
