ABSTRACT:
The present invention is directed to a self-contained desoldering gun having a built-in vacuum pump. The vacuum pump is operated by a low voltage electric motor which is electrically connected in at least partial series with a heating tip. The heating tip reduces the voltage in the circuit and reduces the size of the motor required to operate the pump. In exemplary embodiments, a portion of the heating tip which is not in partial series with the motor is electrically connected in parallel with the motor. In alternate embodiments, the heating tip can include separately formed first and second heating elements, the first heating element being connected in parallel with the motor and the second heating element being connected in series with the motor. Such a configuration allows the second heating element to be energized only when the motor of the vacuum pump is energized. In yet other embodiments, a multi-position switch is used in conjunction with any of the above-described embodiments, and/or is used in still further embodiments to place the vacuum pump in series with a single heating element during operation of the vacuum pump.
