A heat gun is a tool that can be used to perform specific task in a variety of situations. One of the main use of a heat gun is to soften materials or to loosen fasteners. In order to accomplish these tasks with a heat gun, though, the individual has to understand the concept of temperature and how different materials requires different temperatures in order to change state without being destroyed by that heat.
One of the best way for an individual to remember the different temperatures for which different materials will soften or otherwise react is through the use of a temperature chart. Temperature charts indicate the temperature that are appropriate for various applications. Thus, if an individual use the temperature chart, they can ensure that the individual sets the heat gun to the proper temperature for the material that is to be worked on.
How to Use a Heat Gun Safely
Heat guns works by moving heated air across a heating element. The hotter the air that is released from the heat gun, the more heat the air will transfer to the material that is placed in contact with the heat gun. Heat guns are often manufactured with different temperature setting, such as low, medium, high, and maximum heat settings.
Heat guns work within a range of temperatures rather than at a single temperature, and it is these temperature settings that the individual is to utilize to set the heat gun to the appropriate range for the particular task that is to be performed. An individual can make a variety of mistakes when employing a heat gun. For instance, an individual may often start with a heat gun heat setting that is too high for the material that is being treat.
For instance, if an individual uses high heat settings on paint, the paint may bubble; if an individual uses too much heat on wood, the wood may scorch; and if an individual utilizes too much heat on vinyl wrap, the heat may burn the adhesive layer of the wrap. Instead, the individual should of utilized the temperature chart to determine the lowest heat setting for the given task, and only increase the heat if the material do not respond to the lower heat setting. The type of material that will be treated with a heat gun can have an effect on the action of the heat gun itself.
For instance, plastics will deform if the heat from the heat gun is placed in one spot. Metals conduct heat more different than plastics. For instance, if using a heat gun to thaw a frozen pipe, the heat gun should not remain in one spot on the frozen pipe.
Similarly, glass is a material that reacts to rapid temperature change, so the individual should set the heat gun to low heat settings when working with glass to avoid potentially cracking the glass. The nozzle of a heat gun can be used to alter the way that heat is distributed from the heat gun, but it does not impact the temperature settings of the tool. Using a wide nozzle helps to distribute heat across a wide area, making it useful for stripping paint from large areas of an object.
A concentrator nozzle allow for heat to be focused on a smaller area with the heat gun, which is useful for shrink tubing. A deflector nozzle allows for the heat to be redirected at an angle, which can be useful for working in corners or around various pipe. When employing a heat gun, it is important for the individual to take certain safety measures.
For instance, the nozzle of a heat gun can reach very high temperatures quickly. Thus, the nozzle will remain hot even after the individual turns off the heat gun. Consequently, the individual should not place the heat gun onto flammable material.
The individual should wear gloves to protect their hands from the heat from the heat gun, and should use proper ventilation in the area where the individual will employ the heat gun due to the fumes that can exit the air. Finally, in the area where the heat gun will be used, there should be a fire extinguisher present to help provide safety to the individual. An individual can determine whether a heat gun is working properly by observing the reaction of the material to the heat gun.
For instance, if the paint begins to lift with a scraper, the heat gun is at the appropriate temperature. Similarly, if the vinyl begins to stretch without bubbling, the heat gun is at the appropriate temperature. These observations will indicate to the individual whether the heat gun is at the proper temperature for that task.
However, the temperature chart is still an essential tool for the individual to know the starting point of the heat gun setting. Thus, if the individual treats the heat gun temperature as a range, they will be able to successfully employ the tool in a predictable and dependable manner.
