1. Adopting PID programmable temperature control technology, the heating tool is implanted with high-end precision PID program, which supports adjustable or constant temperature with small error. 2. Supports adjustable air volume, large air volume, soft air outlet, and convenient temperature adjustment. The 3 system is equipped with a cold air cooling heating core function, which can extend the life of the heating core and protect the heat gun. 4. It uses a blower to supply air, which has long service life and large air volume. The hot air gun can also use a plug-in ceramic heating core, which is easy and quick to replace. 5 Equipped with Fahrenheit/Celsius conversion function, the temperature display mode is designed to meet the needs of different regional markets, and can be selected according to habits and interests. Provides 6A digital temperature correction function to facilitate correction of temperature deviations caused by replacement of heating elements.
