Maybe you just need to replace the tip of your soldering iron if it's not heating up.
Yes, and make sure the tip is clean and has a nice shiny coat of solder on it. This will really aid in heat transfer. If it's dirty take a wire brush and clean it. Then put a little solder on the tip and let it spread around. Take a damp cloth and wipe the excess off. If the tip is really bad or deformed just buy a new one.
