ABSTRACT:
An electrically heated soldering device includes a housing having an elongated axis with an obtuse angle, an open end, a closed end and an intermediate opening. The outer dimensions of the housing are so dimensioned that the device can be held pencil-fashion with the portion of the housing between the open end and intermediate end grasped by the fingers and thumb of the hand with the portion of the housing between the intermediate opening and the closed end resting on the back of the hand between the thumb and index finger. An electric heating means is substantially coaxially positioned in the housing in spaced relation thereto and is provided with a soldering tip protruding out of the housing through said open end. The open end and the intermediate opening are substantially aligned to produce a chimney-like hollow space surrounding the hot parts of the heating means which carries away excess heat generated within the housing thereby maintaining the housing comfortably cool to touch.
