Yes, just practice on some spare wire. Get some good (Kester is a good brand) 60/40 SnPb (tin lead) solder. Solder is actually a tube with flux in the center. First clean the wire. Then neatly twist the wires together to get a good mechanical bond. The key to soldering is to apply solder to the work (wire) and NOT the iron itself. Make sure you have a clean tip on the iron and add a little solder to the tip to aid in heat transfer. Heat up the work for a second and touch the solder on the copper wire. The solder should wick in. Wick just enough in to where you can see the shiny solder on the outside of the joint. Remember, more (blobs) is not necessarially better. Remove the iron and keep the joint still for a few seconds while the solder cools. Your joint should be shiny with no pits or discoloration (besides flux). If you move the joint while it's cooling you get what is called a cold joint. If this happens simply reheat the joint this is called reflowing. Basically this is a brittle joint that may break and won't conduct as well. Slip a piece of heat shrink tubing over the joint and hit it with your heat gun. Voila!
