A heat gun is a device used to emit a stream of hot air, usually at temperatures between 100 and 550 °C (373 and 823 K; 212 and 1,022 °F), with some hotter models running around 760 °C (1,030 K; 1,400 °F), which can be held by hand. Heat guns usually have the form of an elongated body pointing at what is to be heated, with a handle fixed to it at right angles and a pistol grip trigger in the same pistol form factor as many other power tools.
Though it shares similarities to a hair dryer, it is not meant as a substitute for the latter, which safely spreads out the heat out across its nozzle to prevent scalp burning and has a limited temperature range, while heat guns have a concentrated element and nozzle, along with higher temperatures, which can easily scald the scalp or catch the hair on fire.
Construction
A heat gun comprises a source of heat, usually an electrically heated
Focused infrared heaters are also used for localised heating.
Usage
Heat guns are used in
Heat guns, often called hot air guns or hot air stations for this application, are used in
Household use of heat guns is common. Heat guns and lighter weight hair driers are sometimes used to remove paint splashes and wallpapers. Heat guns are also used to make plastics such as PVC piping pliable for the purposes of bending, to soften wax and adhesives such as that used in electronics, and to thaw out frozen copper pipes. There are also heat gun form factors friendly for food purposes such as melting hard candies, searing meats, or to start a charcoal fire or grill. Heat guns are sometimes used to upholster furniture and repair leather and vinyl goods.
For removing lead paint temperatures below 590 °C (863 K; 1,094 °F) are used to minimize vaporization.[3]
