24A-62 - Tweco Style 24A-62 Adjustable MIG Nozzle, 5/8-inch Bore

Reliable Tweco Style 24A-62 MIG Nozzle

The Tweco Style 24A-62 Adjustable Nozzle is a premium replacement consumable designed for professional MIG welding operations. Engineered to fit Tweco No. 4 and compatible MIG guns (including Radnor 400 series), this nozzle is an essential component for maintaining consistent gas coverage and weld quality. With a standard 5/8-inch (15.9 mm) bore, it provides the ideal balance of gas flow and accessibility for a wide range of welding joints.

Constructed from high-grade 122 DHP copper alloy tubing, this nozzle is built to endure the rigors of medium to heavy-duty welding environments. The material offers excellent thermal conductivity, effectively dissipating heat to prolong the life of the front-end consumables. Rated for applications up to 450 amps, it is robust enough for structural fabrication, heavy equipment repair, and industrial manufacturing.

One of the key features of the 24A-62 is its adjustable slip-on design. It slides smoothly over the standard 34A nozzle insulator, allowing the welder to position the nozzle to achieve the desired contact tip relationship. Whether your application requires a flush, protruding, or recessed tip, this nozzle can be adjusted on the fly to suit the task. The part number is roll-stamped on the exterior for quick and easy identification in the shop.
