12401878 - Tweco Velocity VNH62F Heavy Duty Nozzle 5/8" Flush (2-Pack)

Tweco Velocity VNH62F Heavy Duty MIG Nozzle (Pack of 2)

The Tweco 1240-1878 (VNH62F) Velocity Nozzle is a premium consumable designed to enhance the performance of your MIG welding operations. Sold in a convenient package of two, these heavy-duty nozzles are engineered for professional welders who demand reliability and efficiency. The VNH62F model features a 5/8-inch (16mm) bore, which provides excellent gas coverage for medium to heavy-duty welding applications. The flush tip relationship ensures the contact tip sits even with the nozzle exit, offering a versatile setup for various joint configurations and visibility requirements.

What sets this nozzle apart is the revolutionary Tweco Velocity™ technology. Unlike traditional threaded nozzles that can seize up due to heat and spatter, the Velocity series utilizes a threadless, drop-in style connection. This design not only makes changing nozzles incredibly fast and tool-free but also improves electrical conductivity and heat transfer. The solid copper construction draws heat away from the front end, keeping the nozzle and contact tip cooler, thereby extending consumable life and reducing downtime.

These nozzles are compatible with Tweco Fusion™ and Spray Master™ MIG guns that have been outfitted with Velocity conductor tubes. The integrated spatter shield within the nozzle helps protect the gas diffuser, ensuring smooth gas flow and consistent weld quality. Whether you are working in fabrication, manufacturing, or repair, the Tweco VNH62F nozzle delivers the durability and performance needed to maintain high productivity.
