You can achieve excellent results quickly and easily soldering bullet connectors with The Jigs Up if you use one of the following methods. Method #1, you can use a soldering tip with a 60 degree cone (conical) shaped tip. Insert the hot soldering tip into the vent hole found on the side of many bullet connector cups and fill the cup about 1/4 full with hot melted solder, now insert the tinned wire to be soldered all the way down into the cup. Remove the soldering tip from the connector cup and continue to hold the wire for a few seconds until the solder hardens. Method #2, you can also get excellent results quickly and easily if you use a hot 1/4\" wide spade (screwdriver, chisel) shaped soldering tip put to the side of the connector cup (covering the vent hole if there is one) and filling the cup about 1/4 full with hot melted solder and inserting the tinned wire to be soldered all the way down into the connector cup, then remove the soldering tip from the side of the connector cup and continue to hold the wire until the solder hardens. These methods darn near eliminate solder from flowing down onto the sides and splines of male and female bullet connectors resulting in a quick, simple and easy professional soldering job.
