How heat guns work

A hot air gun operates similarly to a hair dryer in that a fan pulls air into the tool, directs it across an electric heating element, and then out through a nozzle. Basic models usually have just one heat setting and one fan speed and are mainly used for paint stripping. However, more advanced models may have two or three heat settings or even a range of variable adjustments, as well as the option of two, three or variable fan speeds. The heat of any heat gun can be decreased by holding it further away from the surface, but adjusting settings offer more control. However, it is essential to remember that heat guns should never be used to dry hair!

Preparation before use

When using your heat gun, it is important to wear long sleeves and work gloves.
When using a heat gun, it is imperative to don protective apparel, such as long sleeves and work gloves. This will safeguard your arms and torso from heat generated by the gun, while gloves protect your hands and fingers from getting burned. Moreover, the clothing will act as a barrier between your skin and the hot nozzle of the gun.

Keep a fire extinguisher nearby while you work.

Having a fire extinguisher close by while you work is critical to your safety and the safety of others. It is essential to ensure that the fire extinguisher is properly working and fully loaded. Consequently, fire extinguishers should be situated in an accessible spot, such as near your workspace, so that it can be quickly grabbed in case of a fire.

Connect the heat gun directly to a wall socket.

Plugging your heat gun directly into a wall outlet is the best and safest way to ensure that your tool is powered and ready to use. Extension cords and surge protectors should be avoided when using your heat gun, as they can create an unsafe situation if the cable is not rated for the wattage of the gun.

Do not use your heat gun near any combustible materials.

When using a heat gun, it is essential to keep it away from any flammable materials such as paper, cloth, rags, plastics, and other combustible substances, as the intense heat generated by the gun can easily cause them to catch fire or cause a fire hazard. It is also important to keep the gun away from any sources of water or moisture, as the heat generated can cause steam explosions.

Ensure that the air intake is not obstructed.

When using a heat gun, it is essential to ensure that the air inlets are not blocked or obstructed, as this will reduce the airflow and prevent the heat gun from working correctly.

Maintain a distance of at least 2 inches (5.1 cm) from your work surface.

When using a heat gun, it is important to maintain a distance of at least 2 inches (5.1 cm) from your work surface. This is because the heat generated by the gun can cause damage to your work surface if it is held too close for too long. Heat guns can reach temperatures of up to 1000°F, which can easily cause scorching and discolouration of certain materials, including wood and plastic. Additionally, if the heat gun is held too close for too long, it can melt or warp the material to which it is being applied.

Keep the hot nozzle away from your body and clothing.

When handling a hot gun nozzle, keeping it away from your body and clothing is essential. If the nozzle comes into contact with your body, it can cause severe burns. It is also important to never point the nozzle directly at yourself or anyone else when the gun is in use.

Do not insert any objects into the nozzle of the gun.

This could cause a fire or electric shock. Additionally, objects inserted into the nozzle can damage the heat gun, leading to a malfunction. The heat gun is designed to direct air and heat in a specific direction, and any foreign objects can interfere with this flow.

Precautions for use

Use the proper nozzle for the job.

When using a heat gun, choosing the proper nozzle for the job is important. Different nozzles are designed for different purposes. For example, a wide nozzle works best for stripping paint, while a narrow nozzle is best for heat-shrinking tubing and other delicate tasks.

Switch your heat gun onto the recommended setting.

Adjust the temperature setting to the recommended settings for the task, this can usually be found in the product manual. The temperature setting should be adjusted to the lowest temperature possible, which will still get the job done. This will help to ensure that the heat gun does not become too hot and damage the material being worked on.

Continuously move the heat gun not to overheat one single area.

Please only keep the gun in one spot for a short time and move it to a new area after a few seconds. This ensures heat is spread evenly over the entire object and that no single site is exposed to too much heat.

Avoid distractions while you’re using the heat gun.

When using a heat gun, it is essential to make sure you are in a distraction-free environment. Ensure your workspace is tidy and that you are presented in a good way. To protect your eyes and hands from the high temperature, wear protective gear, like goggles and gloves. Keeping children and pets away from your work area is also important, as the heat can cause serious injuries.

Note after use

Turn off your heat gun as soon as you’ve completed your task.

If the heat gun is left on, it will continue to generate high temperatures that can cause damage to the materials you are working with and the surrounding environment. Also, leaving the heat gun on for an extended time can be a potential fire hazard. So, to ensure the safety of yourself and your materials, turn off your heat gun after each use.

Please don’t touch the heat gun immediately after using it.

Please remember that don’t touch it immediately after using the heat gun. A heat gun produces temperatures that can range from 120°F to 1,100°F. These high temperatures can cause serious injury if not handled properly. After using a heat gun, the device should be allowed to cool down completely before attempting to move or store it.
