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. Safer Design With ABS material outside and stainless steel inside, this hot air gun is simple and more durable. Handing part is made of ABS plastic with rhombus designs that cause safe hand-holding with small energizing. Heat Up Quickly The temperature can't be adjusted but it heats up quickly . It can reach at about 200C/390F within a few seconds. Micro-circulation Cooling System Micro-circulation cooling system is adopted. When the air outlet temperature reaches 200 degrees, the temperature of the hot air handing parts does not exceed 28 degrees (approximately). Perfect Tool for DIY Craft Mini hot air gun is a perfect tool for DIY craft works. It can be used for embossing powder, heat-shrinkable film, clay, bump, rubber stamp, fast-drying paint, glue, catalytic adhesive bonding, rapid thawing, shrink PVC for packaging, seal wax patterning, DIY handmade soap or candle.
