Very Helpful, Thank you for the post!

Sorry to bump an old thread to the top, but check out this post. This is a good example on why something that looks as easily as soldering shouldnt be taken so lightly.

I have a cold heat soldering iron. I broke two tips in 5 minutes ($10 USD each). The iron wasnt getting hot enough to melt the solder. I changed the batteries and it worked like a charm.

If your soldering iron isn't melting the solder, change batteries (if it runs on batteries). If it is a plug in, let it heat up longer. Never leave the soldering iron on a part for more than a second or two. If you overheat the sensor, LED, DIP, etc it WILL damage it. It then will eat up a lot of time when your circuit doesn't work and you have to troubleshoot and desolder the part. Always take your time! Thanks Calc for a life lesson that will save me a lot of time!

This will really help me out alot.
Great tutorial!  Thanks for posting it!
Also you would have burnt all the flux out of the solder on your tip by the time you have done one joint. But if your quick, there is really no need to wipe between joints.
I said between each joint because a beginner will typically set up and solder one joint then get the next one ready instead of setting up a series of joints and soldering them all in one go.  Just clean it before you put it back on the stand and prime it when you take it off to use again.
Over time residue will build up on the tip and can cause a decrease in performance. Also if you use too much solder on a joint you can end up with a blob of melted solder on the tip which can dangerous (read hot dripping lead on pants). It's just good practice when using this method to clean the tip off before you put the iron back in the holder.
Who solders in their pants?
yeah i just meant cleaning it between joints
