Heated N₂ gas contributes to increasing solderability

FX-9702 N₂ soldering iron

The FX-9702, N₂ type of FX-9701, consists of the parts shown below.
A station (to control temperature) is required separately.

The compatible tips are T39 series tips

T39 series soldering tips are common to use with the FX-9701 and the FX-9702.
There is no need to keep and use a different tip by a same shape.

Heated N₂ gas produces three effects

1. Improving solderability

Soldering with N₂ gas is effective for lead-free solder, which has poor wettability and spreadability. So, it reduces solder bridging from the components that get the bridge easily.

2. Preventing oxidation

Discharging heated N₂ gas evenly from the top of the soldering tip and nozzle assembly, it prevents the components or the soldering tips from oxidation.

3. Preheating effect

Heated N₂ gas assists soldering tip to heat workpiece effectively. Thus, it allows soldering at a lower temperature without reducing work efficiency.
