From Wikipedia
A heat gun is a device used to emit a stream of hot air, usually at temperatures between 100 and 550 °C, with some hotter models running around 760 °C, 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.
