Using this soldering tip is easy. First, make sure your soldering iron (TS100, TS101, or Pinecil) is turned off and cooled down. Then, carefully replace the old tip with the new C1 T1 Series tip. When soldering, heat the tip and touch it to the solder. The long snub - end design allows you to melt a large amount of solder in small spots efficiently. Remember, the T1 Series has a safety shroud with holes, so don't cover these holes during use. After use, turn off the soldering iron and let it cool. Clean the tip regularly with a damp sponge to remove any excess solder and debris. Store the tip in a dry place to prevent rusting.
