ABSTRACT:
A device for feeding solder wire from a spool to the heated tip of a pencil-type solder iron. The device includes a rigid support strip secured by a pair of spaced bands to the front and rear ends of the elongated handle of the soldering iron. The strip extends longitudinally of the handle and is at one side of the handle. A guide provided with a wire-receiving passage therethrough is carried by the support strip. The guide includes a flexible tube which extends forwardly from the front end of the handle. The forward end of the tube is open and is located near the tip of the soldering iron. A spool of solder wire is rotatably mounted on the support strip near the rear end thereof. A first wheel is adjustably mounted on the support strip forwardly of the spool for fictionally engaging the solder wire extending through the guide to advance the solder wire forwardly through the guide when the first wheel is rotated in one direction relative to the support. A second wheel larger in diameter then the first wheel is secured to one side of the first wheel and is coaxial therewith. The second wheel is adapted to be engaged by the index finger of the hand when the handle of the soldering iron is supported between the index finger and the thumb of the hand. The wheels are adjustably mounted as a unit on the support so that the amount of frictional force exerted by the first wheel on the solder wire can be adjusted.
