Many who have never used a soldering iron are afraid of damaging the equipment, but more importantly the danger to yourself! The soldering iron gets very hot (think, and the solder itself is molten metal. Be sure to wear safety glasses, keep clothes and loose hair, and be careful with your fingers. Better yet, wear protective gloves. Soldering can contain lead, so make sure to wash your hands thoroughly after handling it. It’s also very important to work in a well-ventilated area because the fumes from rosin can cause damage to your lungs when inhaled. To be honest, it makes more sense and preparations than anything else. You must take the proper precautions and you will be fine.

In order to heat properly, your soldering iron must be free of old solder. Once exposed to air, it oxidizes and thus insulates against heat. We want the heat to perform so that we can apply everything quickly and efficiently. The dirty tip means you have to hold the iron on longer and risk damaging the heat on the PCB, and nobody wants that. Keep the sponge wet, and once the soldering iron is fully heated, gently rub against the sponge to remove old solder. You need to make sure that the tip is shiny and nice.
Next, we will “swap” the ends. This will protect the tip and allow heat to perform better through the presence of new solder. On a hot iron, carefully apply a small amount of fresh solder and coat the ends. It should still be shiny if you do it right. As soon as you dip the end you should start soldering your components together. After every few joins, clean and re-tin, and again before putting your iron in storage. This will really help increase the longevity of your tools. A good soldering iron should easily last for years this way.
