Setting temperature

Preheating effect of N2 system allows for setting at low temperature and protecting heat-sensitive components. Look at the following graphs showing the difference of soldering time with / without nitrogen gas in case of HAKKO FX-951 and HAKKO HAKKO FX-838.

FX-951

Thermally-controlled high-power compact type (Digital) as a standard soldering iron for any soldering situation

FX-838

High power 150W soldering station suitable for soldering from large to fine components (Digital)for components requiring a large amount of heat

HAKKO FX-951

Comment As the above, when using N2 system, soldering time is the same even at the 20 ℃ lower set temperature by preheating effect. Preheating alleviates a rapid heat and allows a lower temperature setting, resulting in protecting heat-sensitive components.
