FNIRSI SAG-55: 550 W hot air soldering gun
FNIRSI SAG-55 is a portable 550 W hot air soldering gun with a fan in the handle, powered by the compact power supply included in the set. A PID controller holds the temperature from 100 °C to 450 °C: it constantly compares the sensor reading with the set value and adjusts the heating power, and the manufacturer states fast heating with minimal thermal shock, which extends the life of the heating element.
The 1.54" LCD and the buttons are on the handle, so you can change the temperature and airflow with one hand. You turn on cool airflow with one button when you want to cool the heating element quickly, and you switch between the three saved presets without entering the values again.
- Brushless fan with an airflow of 80 l/min, adjustable in 20 steps
- Heating element compatible with 850 series nozzles, 6 mm nozzle included
- Different colors on the screen indicate the current temperature

Is it right for you?
A good choice if you:
- solder and desolder small SMD components
- want a hot air handle without a separate station on your desk
- often switch settings for different components
Consider another option if you:
- want a Smart Sleep stand that puts the handle to sleep: see FNIRSI SAG-55 Plus
- need a tip soldering iron for wires and through-hole components: see FNIRSI HS-02A

Frequently asked questions
Which nozzles fit the SAG-55?
The heating element is 80 mm long and 21.6 mm in diameter, so 850 series nozzles fit it. A 6 mm nozzle is included, and you can choose others to match the size of the component you are soldering.
Does the SAG-55 remember settings?
Yes, the handle saves three presets of temperature from 100 °C to 450 °C and airflow strength. You switch between them with one button when you change the type of components you solder.
Does the handle switch itself off?
Yes, you can set automatic shutdown to 5, 10 or 15 minutes, or turn it off completely. In the menu you can also set the standby temperature in the range from 70 °C to 100 °C.
