OVERVIEW

Tweco 21-62 Standard MIG Nozzle (Pack of 2)

The Tweco 21-62 is the industry-standard slip-on nozzle designed for use with Tweco #1 (180 Amp) and Tweco #2 (250 Amp) air-cooled MIG guns. This package contains two (2) genuine Tweco nozzles, ensuring you have a spare on hand for continuous welding operations. Engineered with a 5/8-inch (15.9 mm) bore, this nozzle provides excellent shielding gas coverage for medium-to-heavy duty welding applications, reducing the risk of porosity and weld defects.

Manufactured from high-grade copper alloy, the 21-62 nozzle offers superior thermal conductivity and durability, withstanding the high heat and spatter associated with MIG welding. Its slip-on design allows for quick and tool-free replacement, making it a favorite among fabricators for its ease of use. This nozzle is part of the Tweco 21 Series and is designed to sit securely over the 32 series nozzle insulator (sold separately), ensuring electrical isolation and proper concentricity with the contact tip.

Whether you are working in automotive repair, light fabrication, or general maintenance, the Tweco 21-62 delivers consistent performance. The 5/8" bore is the most versatile size for standard wire diameters (0.030" - 0.045"), balancing gas flow velocity and coverage area. By maintaining a clean and spatter-free nozzle, welders can ensure smooth arc characteristics and prolonged consumable life.

FAQ

The 21-62 nozzle fits Tweco #1 (180A) and Tweco #2 (250A) series MIG guns, as well as many other 'Tweco-style' guns in the 180-250 amp range.

The bore size is 5/8 inch (approximately 16mm), which is the standard size for general purpose welding.

This is a slip-on nozzle. It uses friction to hold onto the nozzle insulator.

Yes, this nozzle typically requires the Series 32 nozzle insulator to fit correctly on the gas diffuser.

This package contains 2 nozzles.

It is made of a durable copper alloy designed to withstand high heat and welding spatter.

Yes, although flux-cored welding often doesn't require gas, using a nozzle can help protect the contact tip and gas diffuser from spatter, though some welders prefer a gasless nozzle for better visibility.
