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.


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.

Pre-Order FAQs

View our full list of FAQs here

What is a pre-order?
Pre-orders are products that Hakko Product sells but do not maintain inventory on-hand. These usually include products with short shelf-lives or niche products.

Why should I pre-order?
Purchasing a pre-order item helps us order exactly the right amount of stock. It is a great way to secure an item and reduce wastage!

Having the item as pre-order means that we do not have to stock up our products unnecessarily, which may lead to faulty wiring or electronics in the long run. With pre-orders, you can be rest assured that the purchased products are brand-new and working well, not something that's been left on the shelf for years!

How does a pre-order work?
To secure your item, full payment is due at checkout. Manual payments must be received with the order number in order for us to proceed. When the item arrives at our warehouse, we will process the item within 2-3 business days. Each pre-order product will take approximately 6-8 weeks, but we will definitely ship it out earlier if we have existing stock from a previous shipment. 

How do I know if an item is a pre-order?
All pre-order items will be marked "pre-order" and will have an estimated shipping date in the description.

What if I want to purchase a pre-order item together with items that are in stock?
The entire order will be held until the pre-order item has arrived and all the items can be delivered together. If you would like your in-stock purchases to be delivered first, kindly purchase the items separately.

Pre-order Disclaimer
Because the item has not reached us, we can not guarantee the exact date your item will ship. Each pre-order item has an estimated shipping date but this may be subjected to changes without prior notice, due to many reasons out of our control (shipping, weather, stock level from Hakko Corporation etc).

Unfortunately, we are unable to cancel any orders after payment has been processed. If for any reason we are not able to fulfill your pre-order, we will reach out to you to settle refunds.

Should I contact Hakko Products for a more precise delivery estimate for my order?
Upon receiving your order, Hakko Products immediately requests for the delivery of the item. Our sales will reach out to you if there are any changes to the delivery timings. As mentioned above, we are unable to guarantee the exact date of shipment. We seek your patience and understanding in this matter.

I've been waiting for too long! Can I cancel my pre-order?
By adding to cart and proceeding with payment, you have agreed to the waiting time as stated in each product listing. We are unable to perform cancellations after payment has been processed. Refund requests for pre-orders will only be entertained if two weeks has passed since the stated waiting time and the product has not been delivered. 

For refunds due to defective or damaged goods, kindly reach out to our sales team.

Can't find a specific product?
Contact us via e-mail and we will look into bringing it to our stores! Sometimes, we may plan not to maintain physical inventory for certain products but if it’s something you are interested in, we can have a discussion on it.
