NITROGEN COMPATIBLE HEAVY DUTY SOLDERING IRON

The Hakko FM-2031 Nitrogen compatible Soldering Iron provides a higher mass tip with double the power of conventional 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.

IMPORTANT. PLEASE READ: 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: 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 table below.

Features

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.

Great fit, truly doesn’t slide off heel

I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!

Stay put!
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
Nice and thin, soft, and stay put. I wear an 8 shoe and don’t like a thick sock taking up room. These socks are a bit tight on big toe. Wish they came in large.

The best
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
The best no show socks I have found. Stay in place very well and hold up wash after wash. I have tossed all the other brands I’ve bought over the years and stocked up on these as I was tired of digging through the drawer hoping to find a clean pair.
