ABSTRACT:
A solder dispensing apparatus having a pistol grip handle configuration housing a rechargeable power supply employed for energizing an electric motor which drives a set of pinch wheels for pulling a line of solder from an externally mounted solder spool through the dispensing apparatus and out a solder dispensing extension tip for improving the maneuverability and dispensibility of the line of solder to a designated solder joint through a maze of computer equipment printed circuit board obstructions while minimizing the probability of thermal damage to coaxial cable insulation by direct contact and permitting completion of a cleanly soldered joint on both sides of the printed circuit board within a critical time period for avoiding insulation damage caused by heat accummulation. The method of operation provides for operating a combination on-off, rate control trigger switch for energizing the electric motor through a voltage regulator and for improving sensitivity to speed changes resulting in very slow solder feed rates. A solder replenishing system is included for insuring convenient reloading of and access to the dispensing drive mechanism.
