I recently purchased a 15 watt soldering iron from radio shack, I was practicing with it and I read you are supposed to tin the iron first, so I coated it with solder and wiped off the extra with a moist cloth. I was soldering some speaker wire to an old HD and I noticed I could not get those pins individualy, I have the perfect size solder, kynar wire for the chip but im not using that for practice, any tips on how to solder to individuals insted of 3-4 pins. Also the tip is brown around some parts despite my attempt at tinning, do I need new tips (smaller?).
Any guidence is much appreciated.
