12301120 - Tweco 23-62 Slip-On MIG Nozzle 5/8" Bore (2-Pack)

Reliable Gas Shielding with Tweco 23-62 Nozzles

The Tweco 23-62 Standard Slip-On Nozzle is a staple consumable for industrial welding operations utilizing Tweco MIG guns. This package contains two high-quality nozzles designed to meet the rigorous demands of continuous manufacturing and fabrication environments. The 23-62 model features a standard 5/8-inch (15.9 mm) bore, which is the industry standard for general-purpose MIG welding, offering an ideal balance between gas coverage and accessibility to the weld joint. Engineered by Tweco, a leader in arc welding products, these nozzles are manufactured from a durable copper alloy that provides excellent thermal conductivity, helping to dissipate heat rapidly and prolong the life of the front-end consumables.

Compatibility is key in fleet management, and the 23-62 nozzle is designed to fit the widely used Tweco Professional No. 3 and No. 4 air-cooled MIG guns, as well as the Spray Master 350 and 450 series. The slip-on connection mechanism is a critical feature for productivity; it allows operators to remove the nozzle quickly for cleaning spatter or replacing contact tips without the need for threads that can seize up due to thermal expansion and spatter accumulation. This design relies on the friction fit over the gas diffuser insulator (such as the 34A or 34CT), ensuring the nozzle stays concentric to the contact tip for consistent weld quality.

For procurement managers and shop foremen, stocking genuine Tweco consumables like the 1230-1120 pack ensures that your equipment operates within its specified parameters. Generic nozzles often suffer from inconsistent bore concentricity or inferior copper alloys that degrade quickly under high amperage. By choosing the genuine Tweco 23-62, you ensure stable gas flow, reduced turbulence, and minimized risk of porosity in your welds. This 2-pack configuration offers a convenient way to maintain inventory levels at welding stations, ensuring that downtime is minimized when a replacement is required.

Whether you are welding mild steel, stainless steel, or aluminum, the condition of your nozzle plays a pivotal role in shielding gas performance. The 23-62's robust wall thickness withstands the heat of spray transfer and high-amperage short circuit welding, making it a versatile choice for heavy fabrication, structural steel, and equipment repair.
