FNIRSI Smart hot air gun 550W PID LCD SMD electronics SAG-55 PLUS

The FNIRSI SAG-55 PLUS is an intelligent hot air rework station of 550 W, designed for precision electronics work and SMD repair. It operates across a temperature range of 100 to 450 °C and offers 20 airflow levels, so heat and airflow can be matched to delicate components as well as larger parts. The PID control system keeps the temperature stable and avoids overheating, which supports cleaner soldering and reduces the risk of damaging components.

The heater reaches the set temperature quickly, and a single button switches to cool air mode to cool parts down after soldering. A magnetic stand puts the unit into sleep mode automatically, while built-in sensors monitor operating status and shut off the heating in the event of a fault. The colour 1.54-inch LCD shows all key values clearly, and three saveable profiles make it easy to switch between recurring tasks.
