Wide Temperature Range: Stepless temperature control between 100C to 220C (212F to 428F), making the glue gun suitable for both hot and cold applications. Fast preheating: Fast heating, it can be used normally after 3-5 minutes. High efficiency hot melt glue gun, good performance, adopts energy-saving constant temperature operation and saves 50% energy. The viscosity of the melted glue can be controlled by adjusting the temperature if necessary. Safety Design: Safety insulation double-insulation structure, electrical resistance up to 1800V, dielectric strength greater than 100M, built-in fuse, no voltage, safer. Comes with a bracket to fix the glue gun. Durability: Built-in fuse and ceramic thermistor to prevent overheating, and with automatic thermostat, energy-saving and cooling holes and protection against back heat, ensure longer service life without burning heat. Wide Application: The glue gun can be used to glue different materials, such as: toy models, artificial flowers, decorations, metal, wooden products, cardboard, glass, plastic, leather, circuits, etc. Ideal for DIY at home. improvement projects, home crafts, offices and schools.
