998895 - Firepower 21-50 Style MIG Nozzle, 1/2 in. Bore, 2-Pack

Product Overview

The ESAB Firepower 998895 is a standard replacement MIG welding nozzle designed to meet the specifications of the popular Tweco 21-50 series. This nozzle features a 1/2-inch (12.7 mm) bore orifice, making it the industry-standard choice for a wide range of general fabrication and MIG welding applications. It is engineered to fit Tweco #1 and #2 series MIG guns, as well as compatible systems such as the Lincoln Magnum 100L found on many compact wire welders.

Constructed from high-grade copper alloy, this nozzle ensures optimal thermal conductivity, helping to keep the front-end consumables cool during extended welding operations. The slip-on design utilizes a built-in insulator (sold separately or integrated into the gun neck depending on the model) to maintain a secure friction fit, allowing for quick changes without the need for threads. This specific SKU is packaged as a blister pack containing two (2) nozzles, ideal for retail display or workshop inventory.
