OVERVIEW

The Standard 5/8" Nozzle You Can Trust

If you are running a Tweco gun, you know that the nozzle is the first line of defense against spatter and the key to a clean weld. The Tweco 407741, commonly known as the 24A-62, is the workhorse nozzle found in shops all over the world. With a 5/8-inch bore, it is the "Goldilocks" size—not too tight to clog up instantly, and not so wide that you lose gas coverage in a breeze. It is perfect for everything from general fabrication to heavy structural steel work.

We know that time spent wrestling with a stuck nozzle is time you aren't burning wire. That is why the slip-on design of the 24A-62 is a favorite among welders. When it gets filled with spatter, just twist and pull it off. No threads to strip, no seizing up. You can clean it out with your MIG pliers or a reamer and snap it back on in seconds. The solid copper body handles the heat of high-amperage welding without melting or deforming, meaning you buy fewer replacements over the long run.

This cup fits the classic Tweco #2, #3, and #4 guns, as well as the newer Spray Master models. It sits flush or slightly recessed depending on your specific diffuser setup, giving you good visibility of the puddle without exposing the tip to too much damage. Whether you are using solid wire with C25 gas or running flux-cored wire that needs gas shielding, this nozzle delivers the performance you expect from Tweco.

Why Welders Choose This Nozzle:

  • Easy Swap: Slip-on fit means no fighting with threads when the gun is hot.
  • Tough Build: Thick copper walls resist denting if you drop the gun (or use it as a hammer... we won't tell).
  • Versatile: The 5/8" opening is the industry standard for most wire sizes and positions.

FAQ

This nozzle fits Tweco Professional Series No. 2, No. 3, and No. 4 guns, as well as the Tweco Spray Master series (250, 350, 450 amps).

The bore size (orifice diameter) is 5/8 inch (15.9 mm), which is the standard size for most general-purpose MIG welding applications.

This is a slip-on nozzle. It relies on a friction fit over the nozzle insulator, allowing for easy removal without unscrewing.

You can use a pair of MIG pliers to scrape the inside or a nozzle reamer tool. Using anti-spatter dip or spray beforehand can make cleaning significantly easier.

It is manufactured from a high-quality copper alloy designed for excellent thermal conductivity and durability.

Replace the nozzle when the orifice becomes deformed, when spatter buildup cannot be removed and obstructs gas flow, or if the insulation inside (if applicable to the assembly) is compromised.

Yes, it works for gas-shielded flux-cored welding (Dual Shield). For self-shielded flux-cored welding, a nozzle is typically not required or a thread protector is used instead.
