A heat gun is a versatile tool that emits a stream of hot air, typically ranging from 100°F to 1,200°F. It is commonly used for tasks such as stripping paint, thawing frozen pipes, and drying out wet materials. The adjustable temperature settings allow users to control the heat output for different applications. Heat guns come with various nozzle attachments to focus the heat on specific areas or to spread it over a larger surface. They are often used in DIY projects, woodworking, and even in some industrial applications. Safety precautions are essential, as the high temperatures can cause burns or ignite flammable materials.
