About this deal
The main differences are that cordless models are typically unable to achieve the same peak temperatures as corded models, are not rated in watts, and runtime is dependent on the capacity rating of a battery (measured in amp hours, or Ah.)
Most heat guns offer multiple temperature settings to help you with various DIY projects. The mechanism for changing the temperature varies, though. For example, your heat gun could have a dial that you turn or a button that you press. Fan Speed
Analysis and Test Results
A heat gun’s wattage is a measure of its available power. In general, high-wattage heat guns can discharge air at a higher temperature. For example, one heat gun we researched reaches 1,202 degrees Fahrenheit, while another maxes out at only 572 degrees Fahrenheit. Keep in mind that while a higher-wattage heat gun may provide more heat, it also requires more electrical energy. Temperature Control Some heat guns come with an adjustable fan to control how fast hot air discharges. Speed works in tandem with temperature to provide a customizable heat source. For example, more precise projects, such as heating circuitry, may call for a high-heat, low-speed setting, whereas heating a large wallpapered surface may require a higher fan speed. Nozzle Type
Many heat guns come with specialized nozzles that help you point the heat toward a specific area. Some of the most popular nozzles include cone nozzles that localize the heat and flat nozzles that spread the heat. Other FeaturesWe spent hours researching the best products available before purchasing the most promising heat guns to put through our comprehensive testing. We rated and ranked products head-to-head, comparing their heating performance and capabilities, user-friendliness, ergonomics, and included accessories. We tested performance through a set of practical applications like shrinking heat-shrink tubes onto wiring, stripping paint, and bending PVC pipe.
