Tool that emits a stream of hot air

Heat gun

A heat gun is a device used to emit a stream of hot air, typically at temperatures between 100°C and 550°C (200-1000°F), with some models reaching around 760°C (1400°F). Heat guns are used in a variety of applications, including stripping paint, shrinking tubing, drying, and welding plastics.

Design and Function

Heat guns generally resemble a hair dryer in appearance but operate at much higher temperatures. They consist of a heating element and a fan that blows air over this element, directing the hot air through a nozzle. The temperature and airflow can often be adjusted to suit different tasks.

Applications

Stripping Paint

One of the primary uses of heat guns is to strip paint from surfaces. The hot air softens the paint, making it easier to remove with a scraper.

Shrinking Tubing

Heat guns are commonly used in electronics and electrical work to shrink heat shrink tubing around wires and connections, providing insulation and protection.

Drying

Heat guns can be used to speed up the drying process of various materials, such as paint, glue, and plaster.

Welding Plastics

In plastic welding, heat guns are used to melt plastic surfaces so they can be joined together. This is useful in automotive repair, plumbing, and crafting.

Safety Considerations

Due to the high temperatures involved, it is important to use heat guns with caution. Protective gear such as gloves and safety glasses should be worn, and the device should be kept away from flammable materials.
