Features: 1. T12 soldering head is a composite welding nozzle, which is a combination of heating core, temperature sensor and soldering head.2. Refined copper is used as the main material, excellent thermal conductivity.3. Special electroplating process, long service life, corrosion resistance and oxygen resistance. The tip of the soldering iron is protected by tin coating, which can better stick the tin, resist corrosion and extend the service life. The bottom of the soldering iron is made of special heat-resistant material, which can prevent leakage and short circuit protection.
