Temperature Control Device: The temperature control device is integrated into the hot air gun circuit. When abnormal current and excessive heat are detected, the device automatically cuts off power to protect the circuit, helping prevent hazards such as overheating, melting, or fire. Safer Design: Constructed with an outer layer of ABS material and an inner core of stainless steel, this hot air gun is durable and reliable. The handle is made of high-quality ABS plastic with a rhombus texture for secure and comfortable grip. Heat Up Quickly: The temperature is fixed but heats rapidly, reaching approximately 200°C (390°F) within seconds. Micro-circulation Cooling System: Features a micro-circulation cooling system. When the air outlet reaches 200°C, the handle temperature remains below 28°C (approximate). Perfect Tool for DIY Craft: This mini hot air gun is ideal for various DIY projects. It can be used for embossing powder, heat-shrinkable film, clay, rubber stamps, fast-drying paint, glue activation, adhesive bonding, rapid thawing, shrinking PVC for packaging, seal wax patterning, and crafting handmade soap or candles.
