N2 soldering iron (FX-9704) increases solderability to a fine component

An FX-9704 plus a nozzle assembly makes an N2 iron.
Preheating with heated N2 gas prevents damage by rapid heating to the component, like a ceramic capacitor.
As the N2 gas blocks oxygen, it prevents a tip from oxidation.

N2 system reduces soldering defects!
