Randy,

30 watts doesn't sound like much of a soldering iron to do that. However, try cleaning the surfaces with emery cloth (sandpaper will work in a pinch but its not preferred) and using flux on the parts to be joined. Also, tin the soldering tip with solder and if possible, tin the parts to be joined. That should help you with heat transfer. I would also recommend getting a larger soldering iron or if your budget allows, purchase a resistance unit. I have one and they are the cats butt. It pinpoints heat and does not heat anything up around it. Pricey but if you plan on a lot of jobs then its worth it. Otherwise, a 75 or 100 watt iron should suffice.


Hope that helps you,

Pete
