12301081 - Tweco 23-62-F MIG Nozzle, 5/8" Bore, Flush Tip (1230-1081)

Tweco 23-62-F MIG Nozzle (1230-1081) Overview

The Tweco 23-62-F MIG Nozzle is a premium consumable designed to meet the rigorous demands of industrial welding. Identified by the part number 1230-1081, this nozzle belongs to the widely used 23 Series, making it a staple for fabricators using Tweco Spray Master and Professional Series MIG guns. Specifically, it is engineered to fit the Spray Master 350 and 450 models, as well as the classic Professional No. 3 and No. 4 guns. The nozzle features a substantial 5/8-inch (15.9 mm) bore diameter, which provides a broad umbrella of shielding gas, essential for protecting the weld pool from atmospheric contamination during medium to high-amperage welding.

One of the defining characteristics of the 23-62-F is its "Flush" tip relationship. In this configuration, the contact tip sits flush with the end of the nozzle. This design is favored by many operators because it offers excellent visibility of the arc and the weld puddle without sacrificing gas coverage. It is particularly effective for short-circuit MIG welding or applications where a standard electrical stick-out is required. The flush geometry helps prevent the nozzle from obstructing the welder's view in tight corners while ensuring the gas flow remains laminar and effective.

Constructed from a high-grade copper alloy, the 23-62-F is built to dissipate heat rapidly, reducing the risk of overheating during long weld cycles. The material also resists the adhesion of welding spatter, making it easier to clean and extending the service life of the consumable. This nozzle utilizes a thread-on connection style, which works in conjunction with Tweco's 34A or 34CT insulators. The threaded interface ensures that the nozzle remains concentric with the contact tip, a critical factor for maintaining a stable arc and consistent weld quality. Whether you are working in general fabrication, structural steel, or heavy equipment repair, the Tweco 23-62-F provides the reliability and performance professionals expect from the Tweco brand.
