ABSTRACT:
An electric soldering iron having an elongated handle with an electric heating element attached therein and including a removable tip member located to receive heat from the heating element and a holding member to hold the tip relative to the heating element is improved by forming said heating element as an elongated flat blade heating element having a elongated flat planar heated surface. The heating element is so located in the handle to extend outwardly from the handle. The tip member includes a body having an elongated flat planar heat transfer surface which fits against the planar heated surface of the heating element and receives heat therefrom. The tip member further includes an operative tip extending away from the remainder of the tip member. A retaining tube detachably secured at one end to the handle fits over the heating element and tip member and except for its operative tip and maintains them in a fixed relationship with respect to each other and to the handle. A bowed spring located in the retaining tube biases the planar surfaces of the heating element and tip member into intimate contact with each other. The operative tip is exposed out of the other end of the retaining tube in position for soldering.
