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

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

The Tweco 1220-1204 Velocity Nozzle is a premium MIG welding consumable designed to deliver superior performance in industrial and fabrication environments. Part of the revolutionary Velocity™ series, this nozzle features a 3/8-inch (9.5mm) bore and a flush tip relationship, making it an excellent choice for welders requiring a balance between gas coverage and joint accessibility. The smaller bore size is particularly effective for lower amperage applications or when welding in tighter corners where standard 1/2-inch nozzles may be too bulky.

What sets the Velocity series apart is its innovative design that eliminates traditional threads on the contact tip. Instead, the nozzle itself acts as the locking mechanism, securing the contact tip into the gas diffuser. This creates a solid copper conductor path that drastically improves electrical conductivity and heat dissipation. For the welder, this means the front-end consumables run cooler, last longer, and resist spatter adhesion better than conventional threaded systems. The flush design ensures the contact tip sits even with the nozzle exit, providing a stable arc and consistent shielding gas envelope.

This nozzle is compatible with Tweco Fusion™ MIG guns and Spray Master™ guns that have been upgraded to the Velocity platform. Whether you are working on automotive repairs, light manufacturing, or general fabrication, the Tweco 1220-1204 ensures your equipment operates at peak efficiency. At Josef Gas, we stock genuine Tweco parts to keep your production line moving without interruption.
