12501420 - Tweco 25CT-62 Thread-On MIG Nozzle, 5/8" Bore (2-Pack)

Product Overview

The Tweco 25CT-62 (Stock No. 1250-1420) is a standard-duty MIG gun nozzle designed for professional welding applications. Engineered to fit Tweco No. 2, No. 3, and No. 4 series MIG guns (including Spray Master and Professional models), this nozzle features a 5/8-inch (15.9 mm) bore, which is the industry standard for general fabrication, providing excellent shielding gas coverage for short-circuit and spray transfer modes.

Technical Specifications

This nozzle utilizes a thread-on connection mechanism, which requires the use of a 35CT (Stock 1350-1400) nozzle insulator. The threaded design ensures the nozzle remains concentrically aligned with the contact tip and prevents it from becoming loose during operation, a common issue with slip-on designs. Constructed from a robust copper alloy, the 25CT-62 is built to withstand high thermal stress and resist the adhesion of welding spatter, ensuring a longer service life and reduced downtime for cleaning.

Compatibility

The 25CT-62 is part of the 25CT series and is fully compatible with standard Tweco front-end consumables. It is ideal for medium to heavy-duty MIG (GMAW) and Flux-Cored (FCAW) welding processes where shielding gas is required. The 5/8" bore offers a versatile balance between gas flow volume and accessibility to tight joints.
