Number and position of holes differs according to type of N₂ soldering iron.
This illustration depicts the HAKKO FM-2026.

What is the temperature of heated nitrogen gas?

In case of HAKKO FM-2026 (Station:HAKKO FX-951)

Test condition:

Measure at a point 2mm from the center of tip end with ø0.1CA sensor

Tip shape

T13-D24

Temperature

300℃ and 350℃

Temperature of nitrogen gas varies depending on tip shapes. Setting temperature (ºC) Flow rate of nitrogen gas (l/min.) Temperature of nitrogen gas (ºC) 300 0.5 210 1.0 250 1.5 260 2.0 263 2.5 260 350 0.5 230 1.0 240 1.5 300 2.0 320 2.5 305
