A heat gun is a versatile handheld tool that emits a stream of intensely hot air, typically ranging from **100°C to 600°C**, though industrial models can go much higher. Resembling a hair dryer in shape but far more powerful, it is used for tasks that require targeted thermal application without a flame. Common applications include **stripping paint**, **shrinking heat-shrink tubing**, **thawing frozen pipes**, and **softening adhesives** or plastics for bending. Most models feature adjustable temperature settings and fan speeds, allowing users to fine-tune the heat for delicate electronics or heavy-duty construction projects.
