Using a turbine motor, the rotating wind is naturally soft, and the temperature is concentrated on the heating element, avoiding the traditional UP circuit, precise control of temperature and air volume, large linear adjustment range. Anti-static design, placing the PCB board damaged due to static electricity and leakage. The welding method does not need to touch the solder joints, which can avoid parts displacement and thermal shock. Small design, complete functions, saving working time and easy to carry., Manufacturer: QAXRZCUCD
