12401885 - Tweco VNH62FC Velocity MIG Nozzle 5/8 Inch Flush Copper (2-Pack)

High-Performance Tweco Velocity VNH62FC MIG Nozzles

The Tweco Velocity VNH62FC is a premium heavy-duty MIG welding nozzle designed to deliver exceptional performance in demanding industrial environments. Part of the revolutionary Velocity™ consumable series, this nozzle features a 5/8-inch (15.9 mm) bore and a flush contact tip relationship, making it an ideal choice for a wide range of medium-to-heavy fabrication tasks. The "VNH" designation indicates a Velocity Nozzle Heavy-Duty, engineered to withstand higher amperages and prolonged welding cycles without degrading.

At the core of the Velocity series is a patented design that optimizes the electrical flow and thermal management of the MIG gun front end. Unlike traditional nozzles that rely on threaded connections which can degrade over time, the Velocity system utilizes a solid copper conductor path. This design ensures that the current is transferred more efficiently to the contact tip, resulting in a stable arc and significantly cooler operating temperatures. The VNH62FC is constructed from high-quality copper, further enhancing heat dissipation and durability against spatter adhesion.

The flush tip relationship of the VNH62FC is particularly advantageous for welders requiring a balance between gas coverage and puddle visibility. A flush nozzle allows the welder to get closer to the work surface compared to a recessed tip, which can be beneficial for short-circuit transfer modes or when welding in tight corners. The 5/8-inch bore provides a broad umbrella of shielding gas, reducing the risk of porosity in the weld metal. This package contains two nozzles, ensuring that operators have immediate replacements on hand to maintain productivity.

Installation is seamless due to the Velocity system's intuitive design. The nozzle seats firmly onto the conductor tube or gas diffuser, often requiring fewer turns or a simple push-and-twist motion compared to conventional fine-thread nozzles. This reduces the likelihood of cross-threading or seizing, common issues in high-heat applications. Whether used with Tweco Fusion™ guns or upgraded Spray Master™ torches, the VNH62FC delivers consistent, professional results.
