12401883 - Tweco Velocity Heavy Duty MIG Nozzle 3/4 Inch Flush (2-Pack)

Technical Overview: Tweco Velocity VNH75F2PC Heavy Duty Nozzle

The Tweco Velocity VNH75F2PC is a premium heavy-duty MIG welding nozzle designed for industrial fabrication environments requiring high amperage and extended arc-on time. Part of the revolutionary Velocity consumable platform, this nozzle features a 3/4-inch (19.1 mm) bore orifice, making it ideal for high-deposition welding processes such as spray transfer or flux-cored arc welding where maximum gas coverage is critical to prevent porosity. The 'Flush' tip relationship (indicated by the 'F' in the part number) positions the contact tip even with the nozzle exit, balancing gas coverage with joint accessibility.

The defining characteristic of the Velocity series is its threadless, drop-in technology. Unlike traditional systems where the contact tip screws into a gas diffuser, the Velocity system utilizes the nozzle itself to secure the contact tip. When the VNH75F2PC nozzle is clamped onto the conductor tube, it locks the threadless contact tip in place, creating a solid copper path for electrical conductivity and heat dissipation. This design eliminates the thermal bottleneck found in threaded connections, resulting in a consumable stack that operates significantly cooler. The heavy-duty wall thickness of the VNH series further enhances durability and resistance to radiant heat deformation.

This package contains two (2) nozzles, ensuring operators have immediate replacements available. The VNH75F2PC is compatible with Tweco Fusion MIG guns and Spray Master guns retrofitted with Velocity conductor tubes. It is engineered to withstand the rigors of heavy manufacturing, structural steel fabrication, and shipbuilding.
