When soldering you have to keep in mind one thing: You need heat. Keeping the tip of the iron clean all the time, is the key for easy heat transfer from the iron to the parts that will be connected. Heat transfer is very important, since you don't actually melt the solder itself with the iron. You heat up the parts and then you use that heat to melt the solder. So, let's get down to business.
