The Hakko FM-2031 Nitrogen compatible Soldering Iron provides a higher mass tip with double the power of conventional T17 tips. This iron is ideal for soldering difficult-to-solder heavy ground planes and/or high heat sink applications.

The N2 gas and preheating effect have achieved significant improvement in soldering work! N2 soldering iron providing 140W high output.

Please refer to the User Manual for detailed specifications.


Preventing oxidation
The Nitrogen gas (N2) runs into the nozzle assembly and covers the soldering tip. This prevents the soldering tip and the heater from being readily oxidized and aids in preheating.

Improved wettability
A sufficiently hot soldering tip has a more efficient heat transfer, improving the solder wettability and spreadability. Heated N2 gas improves solderability, and prevents components from getting bridges when working even with lead-free solder or high-temperature solder.

Preheating effect
N2 gas assists soldering iron to heat the objects effectively. It contributes to work at lower setting temperature without spoiling work efficiency.

  • Must be used with T22 tips (not included)
  • Compatible with the Hakko FM-203 soldering station and FM-206 rework system
  • Preventing oxidation
  • Powerful thermal recovery
  • Can be used in combination with your existing high power soldering station, HAKKO FM-206 or HAKKO FM-203.
  • N2 System. Can be used in combination with the HAKKO FX-780/FX-781 and FX-791 to create an N2 System.

IMPORTANT: The FM-2031 can only be attached to the Hakko FM-203 "D" port, and the Hakko FM-206 CH2 or CH3 ports. If you attach the iron to any other port, a grip error or connector error (C-E) will occur.

Note: This is the Handpiece ONLY. This unit does not include neither a soldering tip nor a nozzle assembly. When purchasing this unit, please buy your desired soldering tip and with nozzle assembly together.

Note: Nozzle Assembly Required when using nitrogen
Nozzle assemblies are required in order to properly envelop the tip when using nitrogen. Nozzle assemblies are made to fit specific shape tips. Please choose the appropriate nozzle assembly for your tip selection based on the chart below.
