12601635 - Tweco EL22CT-37F Eliminator Nozzle 3/8 Inch Flush (Pack of 2)

Technical Overview of the Tweco Eliminator EL22CT-37F Nozzle

The Tweco 1260-1635, also known by the part number EL22CT-37F, is a high-performance gas nozzle engineered specifically for the Tweco Eliminator series of MIG guns. This product is supplied in a pack of two, ensuring that professional fabricators have immediate access to replacements during critical welding operations. The Eliminator series is renowned in the industry for its ergonomic design and efficient consumable management, and this nozzle is a key component of that system.

The EL22CT-37F features a 3/8-inch (9.5mm) bore diameter. This relatively small bore size is particularly advantageous for applications requiring access to tight corners or when welding on thinner gauge materials where a focused gas column is necessary to prevent porosity. The nozzle is designed with a "Flush" tip relationship, meaning the contact tip sits flush with the end of the nozzle. This configuration is widely preferred for short-circuit transfer modes and general fabrication because it offers a clear line of sight to the weld puddle while maintaining adequate gas coverage.

Constructed from a robust copper alloy, this nozzle is built to withstand the intense thermal cycling inherent in MIG welding. The copper material provides excellent thermal conductivity, rapidly drawing heat away from the front end of the gun to prevent overheating of the contact tip and diffuser. Additionally, the surface finish is designed to resist the adhesion of weld spatter, making it easier to clean and maintain over its service life. The "CT" in the part number designates the specific coarse thread connection used by the Eliminator series, allowing for fast removal and installation without cross-threading issues.

Proper selection of nozzle geometry is critical for achieving optimal weld quality. The 3/8" bore of the EL22CT-37F is best suited for low to medium amperage applications. Using this nozzle with high-amperage spray transfer modes may result in insufficient gas coverage or overheating; for such applications, a larger bore Eliminator nozzle would be recommended. However, for precision work and standard shop fabrication, this flush, 3/8" nozzle is an industry standard for reliability and performance.
