12401874 - Tweco VNET-37 Velocity MIG Nozzle, Extended Tapered 3/8", 2-Pack

Tweco Velocity VNET-37 Extended Tapered Nozzle (2-Pack)

The Tweco 1240-1874 (Model VNET-37) is a premium MIG welding nozzle designed for the revolutionary Velocity consumable system. This package contains two extended tapered nozzles featuring a 3/8-inch (9.5 mm) bore. The Velocity system is engineered to solve common welding challenges by integrating the contact tip and gas diffuser into a more efficient conductive path, and the nozzle plays a critical role in this assembly. The VNET-37 is specifically crafted with an extended tapered geometry, making it the ideal choice for welders requiring access to restricted spaces, deep V-grooves, or complex corners where standard flush or recessed nozzles cannot reach.

Constructed from high-grade copper, this nozzle ensures optimal thermal conductivity, keeping the front-end consumables cooler during operation. The self-insulated design protects the nozzle and the gun from short-circuiting if it inadvertently touches the workpiece, a common occurrence when welding in tight quarters. The 3/8-inch bore is perfectly sized for short-circuit MIG applications and lower amperage ranges, providing a focused gas column that shields the weld pool effectively without wasting shielding gas. This nozzle is compatible with Tweco Fusion MIG guns and Tweco Spray Master guns that have been upgraded with Velocity conductor tubes.

The Velocity system's unique design eliminates threads on the contact tip, using the nozzle to secure the tip in place (in some configurations) or working in tandem to ensure perfect concentricity. This results in a more stable arc and less downtime for maintenance. Industrial MRO professionals will appreciate the durability and precision of the VNET-37, which reduces the frequency of changeovers and improves overall weld quality in precision fabrication environments.
