OVERVIEW

Maximize Your Weld Quality

As a welder, you know that gas coverage is everything. If your shielding gas is compromised, your weld is compromised. The Tweco 24CT-75-S MIG Nozzle is built for those jobs where you need to lay down serious metal. With a massive 3/4-inch bore, this nozzle provides a wide, stable umbrella of shielding gas, making it the perfect choice for high-amperage spray transfer welding or working on aluminum and stainless steel where atmosphere contamination is a deal-breaker. Stop worrying about porosity and focus on your bead profile.

Built for the Grind

We've all fought with a nozzle that just won't come off after a long day of welding. The heat and spatter can weld a fine-thread nozzle right to the diffuser. Tweco solved this with their Coarse Thread (CT) design. With just a quick twist, the 24CT-75-S comes loose, allowing you to clean out spatter or change your contact tip in seconds, not minutes. This means less frustration and more arc-on time. The heavy-duty copper walls are thick enough to withstand the heat of 400+ amp welding and can take a beating from chipping hammers and nozzle reamers.

Reliable Performance

This 2-pack of nozzles fits the industry-standard Tweco Spray Master and Professional series guns found in shops across the world. Whether you are running a Spray Master 350 or an old-school #4 gun, these nozzles seat perfectly and maintain the correct tip relationship for consistent electrical stick-out. The standard design keeps your tip protected while allowing enough visibility to track your joint accurately. Don't let a clogged or battered nozzle ruin your workflow; keep a pack of these 24CT-75-S nozzles in your toolbox and keep your welds clean.

Why Choose This Nozzle?

  • Easy Maintenance: Coarse threads mean it won't get stuck, even when hot.
  • Better Shielding: The 3/4" opening floods the weld zone with gas.
  • Tough Build: Resists deformation from heat and impact.
  • Perfect Fit: Genuine Tweco design for reliable gas flow.

FAQ

The bore size is 0.750 inches (3/4 inch), which provides a wide gas coverage area suitable for high-heat applications.

This nozzle features coarse threads (indicated by 'CT' in the part number), which helps prevent seizing and makes removal easier.

It is compatible with Tweco Spray Master 250, 350, and 450 series guns, as well as Tweco Professional Series No. 2, No. 3, and No. 4 guns.

This product (SKU 12401434) is sold as a package of 2 nozzles.

A larger 3/4" bore is ideal for high amperage welding or spray transfer modes where a larger envelope of shielding gas is needed to protect the molten pool.

It will only fit Miller guns if they have been retrofitted with a Tweco-style front end (specifically the 24-series system). It is designed primarily for Tweco guns.

The 'S' typically stands for Standard, indicating the nozzle's relationship to the contact tip (usually flush or slightly recessed depending on the insulator used).

Because of the coarse threads, you can easily unscrew it to clean. Using nozzle dip or anti-spatter spray beforehand helps prevent spatter from sticking, and a pair of welpers or a reamer can remove buildup.
