12301016 - Tweco WeldSkill WS2350F MIG Nozzle, 1/2" Bore, Flush, 2-Pack

Precision Gas Shielding for WeldSkill Systems

The Tweco WS2350F (Part No. 1230-1016) is a premium gas nozzle designed specifically for the Tweco WeldSkill series of MIG guns. As an integral component of the 23 Series consumable family, this nozzle is engineered to deliver consistent laminar gas flow, which is critical for preventing porosity and ensuring high-quality weld deposits. The nozzle features a 0.500-inch (1/2") bore diameter, indicated by the "50" in the model nomenclature. This bore size is widely regarded as the industry standard for general-purpose MIG welding, offering an ideal balance between gas consumption and shielding area for short-circuit and globular transfer modes.

The "F" designation in the part number signifies a Flush tip relationship. In this configuration, the contact tip sits flush with the nozzle exit when properly seated in the gas diffuser. This geometry is preferred for many fabrication tasks as it allows the operator to maintain a standard electrical stick-out (ESO) while keeping the nozzle close to the base metal for effective shielding. Unlike recessed nozzles, the flush design provides superior visibility of the arc and the weld puddle, facilitating better control over bead placement. The nozzle utilizes a slip-on connection, securing via friction fit over the nozzle insulator. This threadless design accommodates thermal expansion without seizing and allows for rapid removal during maintenance intervals.

Material selection is paramount for consumable longevity. The WS2350F is fabricated from a high-conductivity copper alloy that efficiently dissipates the intense heat generated by the welding arc. This thermal management helps maintain the structural integrity of the nozzle and reduces the operating temperature of the internal contact tip, thereby extending the service life of the entire front-end assembly. The smooth surface finish of the copper also aids in resisting spatter adhesion, making it easier to clean and maintain optimal gas flow. This product is supplied as a package of two, ensuring immediate availability for replacement requirements.
