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.Field of SearchTool or instrumentHand-manipulative With heat distribution means (i.e., heat applied to extended area) With heated tip or other heat concentration means (i.e., heat applied to localized area) With tip cooling, clamping, or lighting means Convertible Coil or loop-type heating element Integral with tip Detachable tip Threaded With power supply, voltage or current control, or connection and/or disconnection means With thermal control means | |
