- Higher heat-less hang time
- Clean tip (make sure you have a wet sponge to wipe it on)
- Clean solder surfaces (get yourself a little wire brush and clean the leads. SCRAPE the back of pots with a small screwdriver or knife blade.
Electronic solder has a flux core, and extra flux should not really be needed. However, when working on old connections, using a bit of flux or melting a little new solder into the old will help it to reflow.
Flux helps to boil-off impurities, it does not etch. Metals can build up an oxide layer over time that is inpenetrable by chemical means, making the wire brush treatment necessary on occasion.
