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.

Stylish look and great value for special occasions
Size: X-Large, Color: Blue, Size: X-Large, Color: Blue
This suit looks really good in person. The pattern adds a nice touch that makes it stand out without looking too flashy. It is a great option for events like weddings, parties, or prom where you want something a bit different from a basic suit. The fit is slim and modern, giving a clean and sharp look when worn. It feels comfortable enough for a few hours, and the overall shape looks more tailored than expected for the price. The jacket sits well, and the pants match nicely to complete the set. The material is lightweight and decent for occasional use. It does not feel like a premium suit, but it looks good and photographs well, which is what matters for events. The bow tie included is a nice extra and helps complete the outfit without needing to buy more pieces. It may need a quick steam or ironing out of the package to look its best. Also, checking the size chart is important to get the right fit. For the price, this is a very good value. You get a full outfit that looks stylish and put together without spending too much. Great option if you need something affordable for special occasions.

Stylish Statement Suit for the Price
Size: Medium, Color: Gold - Embroidery, Size: Medium, Color: Gold - Embroidery
I really like the black with gold embroidery on this suit - it really will make you stand out. The gold does have a slight green tint to it in certain lighting, but overall I like the unique design and think it looks great. The pants have some flexibility, which made them more comfortable than I expected. I got a Medium - and im usually a 32W. I could see it fitting a 30W or34W too. It arrived in great shape and was not wrinkled at all, though i'm likely going to have to hem the pants 1-2 inches. The pants are neutral and could be worn with other black jackets. I am usually a size 42 bust in jackets, and while the size chart says medium is a 44 bust, i think this fits me like a glove. It also came with a bow tie, which is a nice added bonus. Overall, I think this is a great deal for the price and a solid choice for anyone looking for a versatile standout suit for a formal event or a costume party.

Way better than expected - Not a "costume" at all!
Size: X-Large, Color: Christmas Green
I’m going to be honest: I was fully prepared to open this package and find a cheap, shiny, flammable-looking costume that belonged in a discount Halloween store. Buying a tuxedo on Amazon feels like a total gamble, and I was definitely a skeptic. I couldn’t have been more wrong. This suit is actually fantastic. First off, the fabric. It doesn’t have that "plastic" feel I was dreading; it actually feels elegant and has a nice weight to it. The floral pattern is sharp and the colors are vibrant without being "too much." It looks way more expensive than the price tag suggests. The fit was the biggest surprise. I’m always wary of "slim fit" labels, but this hit the mark perfectly. It’s tailored in the right places without feeling like I’m about to burst a seam if I sit down. I originally bought this thinking it might work for a one-off event, but now I’m genuinely excited to break it out for an upcoming casino night and a wedding later this year. If you’re on the fence because you’re worried about Amazon quality, just go for it. This is a legitimate suit that’ll definitely get you some compliments. 10/10 would buy again.

Showstopper! Incredible Fit and Stunning Floral Design!
Size: Medium, Color: Black
I bought this Mgnaie floral tuxedo for a special event, and I was absolutely blown away by the quality and the fit! Getting a slim-fit suit online can be a gamble, but this two-piece set fit perfectly right out of the package. The blazer hugs the shoulders beautifully, and the pants have a modern, sleek profile without being too restrictive or tight. The floral pattern is exactly what I wanted—bold and eye-catching, yet elegant enough for a formal setting like a wedding, prom, or gala. I received compliments all night long! The fabric feels premium, breathable, and comfortable enough to wear and dance in for hours without losing its shape. For the price, you are getting a high-end look that rivals much more expensive designer tuxedos. If you want to stand out from the crowd in the best way possible, I highly recommend this suit. It is an absolute must-have for any formal wardrobe!

Size: Large, Color: Black
Solid and a typical fit for tux slacks. The coat was vibrant the creases from folding came out super easy and theirs a nice how to guide for ironing/pressing and tie guide. The package is a total outfit bowtie and cufflinks were in mine and they both seem nice and modern.
