Learning the basics of soldering is easier than you may think. Follows is a crash course on how to solder two wires together. This is an essential skill to know when just getting started with electronics, and is a skill that is used often when making Simple Bots. This instructable is the entryway into the whole wild world of soldering. For a more thorough overview of soldering techniques, check out Noah's How to Solder instructable.
Step 1: Solder
Feel free to try slightly thinner or thicker diameter solder, but it is highly recommended that you stick with 60/40 rosin core solder.
It is fair to assume the solder contains lead, unless stated otherwise on the packaging.
Working with lead requires precautionary measures such as:
- Always wash your hands with soap and water after handling solder to wash the lead off.
- Take common-sense precautions like not wiping your eyes, nose or mouth, to avoid absorbing lead.
Step 2: Turn it on
If you have an adjustable temperature soldering iron, set the temperature to around 300 - 350 degrees to start. This should be more than suitable for most soldering jobs.
If your soldering iron is not adjustable-temperature type, just let it heat up for about five minutes before trying to use it.
Step 3: Picking it up
The metal part of the soldering iron is extremely hot and accidentally gripping it will result in terrible burns.
It is generally thought that you should hold the soldering iron as though you were gripping a spoon. Personally, I find it is easier to grip it more like you might hold a pen. Go with whatever technique makes you the most comfortable.
