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 FX951 and HAKKO FX838.

FX951

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

FX838

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

HAKKO FX951
Test method:Measure the time until the workpiece reached to 250℃ at 5-points; setting temperature is 320℃ with nitrogen gas and 340 ℃ without nitrogen gas.:
BoardPaper phenol copper, single-sided
ComponentConnector
Tip shapeT12-D24 without nitrogen gas
