12401894 - Tweco VNH75S Velocity Nozzle 3/4" Bore 1/8" Stick-Out (2-Pack)

Advanced Cooling and Performance with Tweco Velocity

The Tweco 1240-1894 VNH75S Velocity Nozzle represents a significant leap forward in MIG gun consumable technology. Designed for the professional welder who demands reliability and efficiency, this heavy-duty nozzle is part of the renowned Velocity series. Unlike traditional threaded nozzles that can seize or degrade over time, the Velocity system utilizes a threadless, drop-in design. This innovation not only speeds up consumable changes but also creates a more solid copper path, significantly improving electrical conductivity and heat dissipation.

This specific model, the VNH75S, features a large 3/4-inch (19.1 mm) bore, making it particularly well-suited for high-amperage applications where gas coverage is critical, such as spray transfer welding on heavy plate. The "S" designation indicates a 1/8-inch contact tip stick-out. This configuration allows the contact tip to protrude slightly beyond the nozzle face, providing the welder with better visibility of the arc and puddle, which is essential for precision work or when navigating tight joints.

Supplied in a convenient pack of 2, these nozzles are built to withstand the rigors of industrial environments. The heavy-duty copper construction resists spatter adhesion and deformation under high heat, ensuring a longer service life compared to standard duty nozzles. By maintaining a cooler operating temperature, the Velocity system helps extend the life of your contact tips and gas diffusers, reducing overall downtime and operational costs.
