SI-20U-T Replacement Tip for SI-20U USB Portable Soldering Iron
This tip is specifically designed for the 8W USB Portable Soldering iron. Simply unplug the cable and let the unit cool down. Twist the metal nut in the front to remove the tip and pull the old tip out. Replace the old tip with the new one and twist only the nut back on. The soldering tip must never be rotated as it will loosen inside and not work properly. Plug in the cable and begin to solder, the first time it will take 10 minutes for the tip to stop smoking.
