OVERVIEW

Reliable Tweco Style 24CT-37S MIG Nozzles

Optimize your welding operations with this 2-pack of Tweco Style 24CT-37S MIG nozzles, specifically engineered for industrial durability and precision. Designed to fit Tweco 300 and 400 Amp MIG guns, these nozzles are an essential consumable for professionals requiring consistent gas coverage and reliable performance. The 24CT series is renowned for its robust construction, and this specific model features a 3/8-inch (9.5mm) bore, making it an excellent choice for applications requiring tighter access or focused gas flow.

The defining feature of the 24CT-37S is its coarse thread design. Unlike fine threads that can easily cross-thread or seize due to thermal expansion and spatter accumulation, the coarse threads on this nozzle ensure quick and hassle-free removal and installation. This is particularly beneficial in high-volume production environments where downtime for consumable changes must be minimized. The nozzle seats securely onto the 34CT gas diffuser, ensuring proper electrical insulation and gas sealing.

Manufactured from high-grade copper alloy, these nozzles provide excellent thermal conductivity, helping to keep the front-end consumables cooler during extended welding cycles. This thermal management reduces the adherence of spatter, extending the life of the nozzle and reducing the frequency of cleaning. Whether you are working on general fabrication, structural steel, or automotive repair, these replacement nozzles offer the fit, form, and function of the original equipment at a competitive value.

FAQ

These nozzles are designed to fit Tweco No. 2, No. 3, and No. 4 series MIG guns that utilize the 34CT gas diffuser.

The bore size is 3/8 inch (approximately 9.5mm), which is ideal for tighter joints or when better puddle visibility is required.

Coarse threads are less likely to cross-thread or seize due to heat expansion and spatter, making them easier to remove and install compared to fine-thread nozzles.

No, this is a 2-pack of nozzles only. You will need a compatible 34CT gas diffuser installed on your gun to use these.

This product is a high-quality generic replacement compatible with Tweco systems, often referred to as 'Tweco Style'. It replaces OEM part number 1240-1404.

They are rated for use with MIG guns operating between 300 and 400 Amps.

This product is sold as a package of 2 nozzles.

While primarily for gas-shielded MIG welding, you can use it for gas-shielded flux-core. For self-shielded flux-core, a nozzle is typically not required or a thread protector is used instead.
