What is Heat Gun ?
A heat gun is a device that generates hot air and is commonly used in industries for different applications. It acts as a versatile tool with high-temperature control and can be used for paint stripping, soldering, bending, welding, shrinking and thawing. With its varied uses, heat guns have become an indispensable tool in many a tradesperson’s kit.
Its high temperature and airflow output make it an efficient tool in shaping or removing hard materials like plastic and metal. In this technological age, heat guns are becoming more popular in the household for day-to-day use such as defrosting and drying purposes, making them a household necessity. In this article, we will go through the various aspects of heat guns and their uses in detail.
How does a Heat gun work ?
A heat gun is an incredibly useful tool that allows the user to manipulate and shape a variety of materials. From bending plastics to stripping paint, the uses for a heat gun are endless. But how does this tool work?
At its core, a heat gun is essentially a glorified hair dryer. It uses electricity to send heat through a nozzle, which can be pointed at a specific surface to apply heat. The difference lies in the power and intensity of the heat being produced.
The heat gun heating element is a coil of wire that is electrically heated. The wire in the coil has a resistance which converts electrical energy to heat. The heating element in a heat gun is designed in a way that it doesn’t emit any flame or sparks that could be dangerous and harmful. The air entering the heat gun is mixed with hot air, which is then forced out through the nozzle tip.
The air is heated by passing over the heating element before it is blown out, meaning that the heat can be adjusted by changing the amount of air that is forced through the heating element.
When the heat gun is turned on, the electric current flows through the heating element, causing it to become hot. This heat is then transferred to the surrounding air and directed towards the object or surface being heated.
Most heat guns have adjustable heat settings, allowing the user to control the intensity of the heat output. Some heat guns also have additional features, such as a temperature control, fan speed control, and nozzle attachments for directing the airflow.
How hot do heat guns get ?
A heat gun temperature can range between 100 to 1,200 degrees Fahrenheit, depending on the model and setting. Most heat guns come equipped with a temperature selector switch so that the user can adjust the setting depending on the job and the material being worked on.
Major Components of Heat Gun
The major components of a heat gun include the heating element, the fan, and the nozzle. The heating element is made up of a high resistance wire wound on an insulating support. When electrical current flows through the wire, it begins to heat up and emit heat. The fan then pulls air into the heat gun and past the heating element, where it heats up before being expelled through the nozzle.
The nozzle is a vital component of the heat gun as it is responsible for controlling the temperature and directing the flow of air. The nozzle can come in a variety of shapes and sizes, with some being a simple tube, and others being curved or angled to direct heat in a specific direction.
When using a heat gun, it is important to remember to keep the nozzle moving to avoid overheating and damaging the material being worked on. When the heat gun is pointed at a single spot for too long, the temperature can become dangerously high and cause the material to bubble, warp, or even ignite in some cases.
Application of Heat Gun
One of the main applications of a heat gun is for stripping paint. The heat gun’s high temperature causes the paint to soften and come away from the surface, making it easy to remove. This method is much more efficient than traditional methods such as scraping or sanding, which can take a lot of time and effort. The heat gun can also be used to remove adhesive and decals.
Another use of a heat gun is for bending plastics. When heated, plastic becomes pliable, making it easy to mold and shape. The heat gun’s nozzle can be used to direct heat onto specific areas of the plastic, allowing it to be manipulated into different shapes and forms.
Conclusion
In conclusion, a heat gun is a powerful tool that can be used for a variety of tasks. Its heating element, fan, and nozzle work together to create hot air that can be directed and controlled. Knowing how a heat gun works is essential for using it safely and effectively. Whether you are stripping paint or bending plastics, a heat gun is a versatile tool that can make the job easier and faster.
