N2 System

Soldering time

Soldering process time can be saved by preheating effect of N2 system.
Look at the following graphs showing the soldering time difference with / without nitrogen gas in case of HAKKO FX-951 and HAKKO FX-838.

as a standard soldering iron for any soldering situation
img 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 HAKKO FX-838

Comment
Soldering time with nitrogen gas can be saved by preheating effect as the above test results. Preheating the workpiece enhances the solder flow so that the solderbility will improve.
