1、Using high‑tech ceramic PTC thermistor heating component, the heating speed is fast, the PTC thermistor will automatically maintain a constant temperature when the temperature reaches the set temperature, saving energy consumption and prolonging the service life. 2、The electrical insulation strength does not break down when it is energized at 3750V/min. The product can be used normally under AC voltage. It's not limited by voltage fluctuations. Built-in safety fuse making it safer to use. 3、No pouring and no leakage; heat insulation is installed at the end of the barrel to extend the service life of the silicone sleeve, thereby making the glue gun life longer. 4、The gun nozzle is made of brass, which is more resistant to high temperature than ordinary aluminum nozzles. The handle designs conforms to the designs of human hand dynamics. It feels good and no fatigues after long-term use. 5、The glue handle is made of international new environmentally friendly materials, which has a longer service life, rapid heating and automatic constant temperature.
