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 materials. It operates at different temperature settings, allowing users to control the heat output for specific applications. Heat guns are commonly found in workshops and home improvement projects. They can also be used for crafts, such as shrinking plastic wrap or bending plastic materials. Safety precautions are essential when using a heat gun, as the high temperatures can cause burns or ignite flammable materials.
