Heat Guns are common tools which are good for applying heat shrink tubing, heating solder sleeves, desoldering circuit boards, plastic welding, and a wide variety of applications that require the highest degree of precision and control.
Here are some useful safety guideline when operating heat guns:
Maintain air circulation when operating
It’s recommended to keep fresh air circulating in the area when working with heat guns. Softening paint may release solvents. Vapor may be generated when soldering or welding plastic.
Avoid working in the presence of water
Heat Guns are electrical power tools and are dangerous to use above or near the water.
Have a trial run first before operating
It’s suggested to always have a trial run before operating your heat gun. Check the airflow rate, temperature and compatibility of hot air with your target materials.
Be careful to avoid personal injury. Most heat guns’ air temperature is over 200°C, which can cause hair and skin damage. Please do not aim the heat gun directly at hair, skin or other unprotected body parts. The following image shows an example of proper body protection when using a heat gun measuring around 625-725°F (~330-385°C).
