How Do Heat Guns Work And what are they for?
A heat gun releases a stream of hot air making it fall under the category of power tools. Superficially (both in shape and construction) it is similar to a hair dryer, but a heat gun operates at a much higher temperature. The type of work it usually belongs to are within the fields of physics, material science, chemistry, engineering, and other types of environments such as laboratories or workshops.
The heat gun can be used for peeling and drying paint, applying heat shrink pipes, drying moisture from the wood, bending plastic and softening. They are also used in electronics to desolder the components of a circuit board. Usually, the air is discharged at temperatures ranging from 100 to 550 °C (200 to 1000 °F), and in some models, even hotter at 760 °C (1400 °F).
Parts of a Heat Gun
Heat guns are usually quite simple, see details below for their components:
Uses and Applications of Heat Guns
As we said before, the heat gun is used for different tasks in different areas so in this section we develop a little more usefulness and recommend information for its care:
It is necessary to do specific techniques to remove the paint effectively.
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.
