How to solder: 1).Determine the right temperature for your project. Which temperature to use depends on the materials you're joining and the kind of solder you're using. 2).Once your iron is heated to the appropriate temperature, pick up the iron by the handle in one hand and hold a piece of solder in the other hand. Hold the hot iron to the place where the two metal components will meet for about a second to heat them up. You want to heat the metal parts, not the solder itself. 3).Touch the solder to the heated components. As the solder melts, it will flow into the gaps it needs to fill. Continue to feed in solder until a sufficient amount is melted.
