A technique I learned and used: take a thick gauge copper wire, like the one used for house wiring or just a tad thinner, and tightly wrap it around your 100W tip, as many turns as fits. Then allow about 1-1/2 to 2" long tip, shape it with a file to a bevel. It is excellent to use for small wires. The ratio of tip length to number of turns dictates the temperature.
