Using the KU soldering tip is easy. First, make sure your soldering iron (TS100, TS101, or Pinecil) is turned off and cooled down. Then, replace the old tip with the KU tip. When using it, heat the soldering iron to the appropriate temperature. For delicate work, use a lower temperature. This tip is great for getting into small spaces, so you can do detailed soldering jobs. When you're done soldering, turn off the iron and let it cool completely. To maintain the tip, clean it regularly with a damp sponge. Avoid using too much force when cleaning to prevent damage. Also, store the tip in a dry place to keep it in good condition.
