FNIRSI SAG-55 Plus is an intelligent hot air gun for precision electronics work and SMD rework, offering up to 550 W of power, a temperature range of 100–450 °C, and 20 airflow levels. With PID control, fast heating, a cold air mode, automatic sleep in the magnetic stand, and a clear color LCD display, you get safe, stable, and comfortable control for soldering and component rework.
The FNIRSI SAG-55 Plus hot air gun is designed for everyday soldering and electronics rework—from delicate SMD components to more demanding service tasks. Stable output and smart features increase precision, reduce working time, and minimize the risk of overheating components.
Key benefits and features:
- Digital PID temperature stabilization with real-time monitoring for consistent, accurate heating.
- Fast heat-up to the target temperature and a cold air mode for immediate cooling after work.
- 20-step airflow control up to 80 L/min for both gentle and high-power use.
- Brushless fan with low noise (< 65 dB) for comfort during longer sessions.
- Intelligent safety system—in case of a fault, it automatically turns off heating to protect the device and the user.
- Magnetic stand + automatic sleep mode for safe placement and gentle cooldown of the heating core.
- 3 user presets for temperature and airflow for quick switching between tasks.
- 1.54" color LCD display (240 × 240 px) for an instant overview of temperature, modes, and settings.
- Compatible with 850 standard nozzles for broad expandability and easy accessory availability.
