The heat gun is designed with a dual fan speed selector that makes high and low fan speed adjustments in order to dial the amount of heat that’s needed. On the top of the device, one can see an LCD screen with push-button controls. It comes with an ergonomic stand to allow installing the gun.
A heat gun is a device used to emit a stream of hot air, usually at temperatures between 100 °C and 550 °C (200-1000 °F), with some hotter models running around 760 °C (1400 °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 trigger, in the same general layout as a handgun, hence the name. A lighter duty heat gun is similar to a portable Hair dryer.
Construction[edit]
A heat gun comprises a source of heat, usually an electrically heated element, but sometimes a gas flame; a mechanism to move the hot air such as an electric fan, unless gas pressure is sufficient; a nozzle to direct the air, which may be a simple tube pointing in one direction, or specially shaped for purposes such as concentrating the heat on a small area or thawing a pipe but not the wall behind; a housing to contain the components and keep the operator safe; a mechanism to switch it on and off such as a trigger; a handle; and a built-in or external stand if the gun is to be used hands-free. Although not called such, a hair dryer is a form of low-temperature heat gun. Gas-powered soldering irons sometimes have interchangeable hot air blower tips to produce a very narrow stream of hot air suitable for working with surface-mount devices and shrinking heat shrink tubing.
Focused infrared heaters are also used for localised heating.
Usage[edit]
Heat guns are used in physics, materials science, chemistry, engineering, and other laboratory and workshop settings. Different types of heat gun operating at different temperatures and with different airflow can be used to strip paint, shrink heat shrink tubing, shrink film, and shrink wrappackaging, dry out damp wood, bend and weld plastic, soften adhesives, and thaw frozen pipes.[1] Heat guns, often called hot air guns or hot air stations for this application, are used in electronics to desolder and reworksurface-mountedcircuit boardcomponents.Heat guns are also used for functional testing of overheat protection devices, in order to safely simulate an overheat condition.

Household use of heat guns is common. Heat guns and lighter weight hair driers are sometimes used to remove paint splashes and wallpapers. Heat is also used to bend plastics with the help of the gun and soften some types of adhesives. These guns also help in thawing frozen pipes and shrink wraps. Heat guns can be used to roast coffee beans, sear meat and melt sugar, chocolate, etc. They can also be used to bend PVC pipes. Heat guns are sometimes used to help upholster furniture and repair leather and vinyl goods.[1]
For removing lead paint temperatures below 590 °C (1100 °F) are used to minimize vaporization.[2]

In addition to being used as a paint remover, the heat gun is also used to soften floor tiles and linoleum, loosen brittle adhesives, activate thermo-shrinkable plastic materials and defrost frozen water pipes.

Use Recommendations for Heat Guns
The heat gun produces extremely high temperatures (up to 593 °C - 1100 °F). It must be used with care to prevent ignition of the combustible material. Never allow liquids to enter the heat gun, nor immerse any part of the heat gun in a liquid. Make sure the inlet openings and cover are clean and free of obstruction. If necessary, clean the inlet opening and cover with a soft, dry brush.

Clean heat gun covers only with mild soap and a damp cloth. Do not clean the heat gun with household cleaners, as many have chemicals that can cause considerable damage to the heat gun. You should use gasoline, turpentine, lacquer, paint thinner, dry-cleaning fluids or similar products when cleaning it.

Wait for the nozzle to cool down to room temperature before storing the heat gun. Over time, the nozzle will darken due to high temperatures. It is normal and will not affect the operation of the nozzle.
