12201204 - Tweco Velocity MIG Nozzle 3/8" Flush (1220-1204)

Tweco 1220-1204 Velocity MIG Nozzle – 3/8" Flush

Upgrade your MIG welding experience with the Tweco 1220-1204 Velocity Nozzle, engineered for professional welders who demand reliability and longevity from their consumables. This nozzle is a core component of the Tweco Velocity™ system, which has redefined MIG gun performance by addressing the most common failure point: the threaded contact tip. By utilizing a threadless, drop-in contact tip secured by this nozzle, Tweco has created a system that offers smoother arc stability and significantly reduced downtime.

The 1220-1204 (VNS-37F) model features a 3/8-inch bore and a flush tip recess. The flush configuration is versatile, offering excellent visibility of the weld puddle while maintaining a robust shielding gas column, even in drafty shop conditions. The 3/8-inch opening is tighter than standard nozzles, increasing gas density at the weld pool, which is beneficial for short-circuit MIG welding or when working on thinner gauge materials where precision is paramount.

Constructed from high-grade copper, this nozzle withstands the thermal shock of high-amperage welding. Its smooth surface finish resists spatter buildup, and the absence of internal threads means you won't struggle with cross-threading or seized parts during changeovers. Designed to fit Tweco Fusion and adapted Spray Master guns, this nozzle is an essential addition to your welding toolkit.
