12401875 - Tweco Velocity VNH75 Heavy Duty MIG Nozzle 3/4" Bore (2-Pack)

High-Performance Tweco Velocity VNH75 Nozzles

Optimize your welding operations with the Tweco Velocity VNH75 MIG Nozzle, engineered for the modern welder. This package contains two (2) heavy-duty nozzles designed to fit Tweco MIG guns equipped with the Velocity consumable platform. The Velocity series represents a leap forward in MIG technology, featuring threadless, drop-in consumables that simplify maintenance and improve arc characteristics.

The VNH75 is distinguished by its 3/4-inch (19.1 mm) bore orifice. This larger diameter is critical for high-amperage welding processes, such as Spray Transfer or Pulse MIG, where a wider gas envelope is necessary to fully shield the molten weld pool. The heavy-duty copper alloy construction provides excellent thermal conductivity, pulling heat away from the front end of the gun to extend the life of both the nozzle and the contact tip inside.

Unlike traditional threaded nozzles that can seize or cross-thread, the Velocity nozzle works in tandem with the Velocity gas diffuser and contact tip to create a solid, electrically efficient connection. This design minimizes voltage drop and ensures a stable arc, even in demanding industrial environments. Upgrade to the VNH75 for superior durability and gas flow management.

Technical Benefits

• Enhanced Cooling: Velocity design dissipates heat faster than standard consumables.
• Stable Gas Flow: Smooth internal geometry reduces turbulence for better shielding.
• Easy Changeover: No threads to damage; simple slip-on/twist-lock mechanism.
