@ NYE - if you don't have an iron, pick up a 30 watt iron and some solder. Get the iron hot and moisten the tip with solder. if it doesn't adhere, scuff it lightly and try again. Keep a moist sponge or rag nearby to clean the tip.
As D'Wasp said, just reflow - but having your own spool will help if the tip gets dry, tacky, or you find a joint that is too dry.
@ Astro14 - I've read your posts. You can do this. Pick up an iron and some solder and practice on scrap 14 to 24 gauge wire and you'll get the feel for it.
