Types of Heat Gun
You may find heat guns with diverse features, but they can all be categorized into four types based on their operational mechanism: electrical, gas, industrial, and infrared.
Electric heat guns
Electric heat guns are popular among other types. They come in corded and cordless forms and different sizes, and their features and temperature range also vary. Moreover, electric heat guns are more durable than battery-powered heat guns.
Gas heat gun
Gas heat guns are quite expensive. They operate using butane or propane gas. Thus, to use this gun, you need to refill gas, which makes it expensive and less convenient. However, it’s very popular among professional painting or plumbing jobs.
Industrial heat gun
Such heat guns are designed and manufactured for mega-construction-based projects. Thus, it comes with a high heat level and fan setting. If you are looking for heat guns for a factory job or automotive projects, then an industrial heat gun is what you are looking for.
Infrared guns
Infrared guns are innovative designs with modern features and a budget-friendly price. They are suitable for small projects or casual use. Nevertheless, the temperature range is less than that of other types of heat guns.
What Can You Use a Heat Gun for?
Heat is popularly known for paint stripping. However, heat gun uses extend to many other types of jobs. A heat gun can be used on various types of surfaces, such as brick, wood, concrete, metal, and stone. It can also be used for plumbing jobs where you need to blend plastic pipes or dry materials using heavy temperatures. Additionally, you can use it for melting or breaking down adhesives or glues or defrosting pipes.
No matter which purpose you use the device for, you need to maintain proper safety and caution every time. Since the device generates high temperatures, it can damage other parts like solder joints or scotch connectors.
How to Use a Heat Gun to Remove Paint?
Here, you will find the detailed procedure for stripping paint with a heat gun. This device can raise the temperature to 649 °C, so you can use it to remove paint, shrink wrap, defrost pipes, and so on. To deal with such extensive temperatures, you need to take some preparation and safety measures while operating the device.
Things you will need for safety purposes:
A heat gun, long gloves, long-sleeve shirt or clean work clothes, and additional protective items if needed such as goggles, powered air-purifying respirator (PAPR), an organic vapor cartridge. fire extinguisher and a fire-retardant coat.
Step 1: Initiating the heat gun
Once you are well equipped with all the materials and wear protective items, you can begin using the device. If you are using an electric heat gun, you need to plug it into the wall socket. If you are using a gas heat gun, make sure the gun is properly refilled with gas.
Step 2: Generating the gun temperature
Now, let the device generate the temperature. At this stage, you need to make sure it is away from flammable materials such as paper, curtains, gas, or chemical solvents.
Since the device generates heat, drawing air into the rear of the gun, you also need to ensure that the air inlets are properly open. Otherwise, the gun can overheat and cause an accident. If the device is in your hand, be careful not to block the air inlet section with your hand.
Step 3: Removing the paint
When the device is hot enough, it’s time to apply it to the targeted place. To remove the paint, attach a suitable nozzle to the top of the gun. This attachment will help you to apply proper heat to the painted spot.
If your device has a specific setting for paint removal, set it to the designated heat option and use it. While using the device, keep it at a 45-degree angle and at a distance to reduce the risk of damaging the work surface and your skin.
To be specific, make sure the device’s nozzle is around 2 inches from the work area. As the paint starts coming out, you can get the device closer but keep a consistent distance from the surface. To do that, start working in a small section and wait for the paint to bubble.
Once the paint bubbles up, move the device back and forth over the targeted spot. Now, use an angled scraper to remove the paint from the surface.
Step 4: Cooling down the device and storing
When you are done using the heat gun, turn off the switch. Even if you take a break in the middle of the work, always turn off the connection and set it down in a safer, insulated place.
When you are done working with the heat gun, make sure to cool it down completely. During this time, plug it off and keep it in a safer place out of everyone’s reach. It usually takes around half an hour to completely cool down.
