A heat gun is a versatile tool that emits a stream of hot air, typically used for various tasks such as stripping paint, thawing frozen pipes, or drying out damp surfaces. It operates at different temperature settings, allowing users to control the heat intensity based on the specific application. Heat guns are commonly used in DIY projects and professional settings alike. They can also be used for tasks like shrinking plastic wrap or softening adhesives. Safety precautions are essential when using a heat gun, as the high temperatures can cause burns or ignite flammable materials.
