1. For better results, continuously rotate the connector when applying heat with a heat gun to make the terminal evenly heated.
2. Keep the heat gun at a distance of 3-5cm from the Solder Seal.
3. Do not set high temperature at the beginning of use, otherwise the solder in the middle might not melt along with the shrunk tubing. Direct the heat first at the solder as it takes higher temperature to melt than the shrinkable tube.
