What is a heat gun manufactured for? The answer is to generate heat to work on different metals. So, the power tool should facilitate a higher temperature setting. However, there is a small trick when it comes to the heat range of the instrument.
Firstly, the lower end of the heat generation needs to be minimal, and secondly, the higher range requires maximum range.
Besides the temperature range, you should also focus on the variable temperature settings. Usually, most heat guns provide two variable temperature settings. But some units feature three to five stages, which are ideal for controlled and customized applications.
