A heat gun is a versatile device that blows hot air, used across many applications, such as paint removal, drying, plastic welding, and heat shrinking. The tool functions similarly to a hairdryer but operates at much higher temperatures, with many models offering adjustable heat settings to suit different tasks.

Heat guns are particularly helpful for stripping paint or adhesives, as the hot air softens the material, allowing it to be easily removed. In craft and electrical work, heat guns can shrink tubing around wires or help shape plastics. Safety features like overheating protection and temperature control make modern heat guns safe and easy to handle, even for prolonged use.
