    • When you desolder, apply the tip of the soldering iron to the soldered joint for approximately 5 - 10 seconds.

    • The soldered joint will turn to a liquid consistency. At this moment, remove the wire and soldering iron.

    • Repeat each of the following steps for the second soldered joint.

  • Soldering irons are dangerously hot. The soldering iron should only come in contact with joints being desoldered or soldered.

  • Make sure to allow time for your soldering iron to heat up before using it.

  • Make sure the tip of the soldering iron is cleaned so the tin on the tip is exposed. This will allow the soldering iron to work efficiently.
