【High Power and Quickly Heat Up】: With max power 300W, it can reach at about 300°C easily within a few seconds which can make the work more quickly and more efficient; With Nickel-chromium heating wire structure&mica bracket, it can speed up heat dissipation and extend the service life 【Safer And More Durable】: With ABS material outside and stainless steel inside, this hot air gun is simple and more durable.Handing part is made of high quality ABS plastic with rhombus designs that cause safe hand-holding with small energizing. 【Temperature Control Device】: The temperature control device is arranged in the hot air gun circuit. When the current abnormally rises to a certain height with abnormal heat, the temperature control cuts off the current itself, which protects the safe operation of the circuit and eliminates the occurrence of dangerous situations such as high temperature melting and fire. 【Micro-circulation Cooling System】: Micro-circulation cooling system is adopted. When the
