12441030 - Tweco 24A-87 MIG Nozzle, 0.83-Inch (21mm) Bore, Slip-On

Heavy-Duty Gas Coverage for Industrial MIG Welding

The Tweco 1244-1030 (Model 24A-87) is a high-performance MIG welding nozzle designed for heavy industrial applications. Featuring a substantial 0.83-inch (21mm) bore, this nozzle is engineered to provide a wide and stable shielding gas envelope, which is critical when welding at high amperages or with large diameter wires. The large opening minimizes turbulence and ensures that the weld pool remains fully protected from atmospheric contamination, reducing the risk of porosity and defects in critical welds.

Manufactured from high-grade copper alloy, the 24A-87 nozzle offers excellent thermal conductivity and durability. It effectively dissipates heat generated during prolonged welding sessions, extending the service life of the consumable and the front-end parts of the MIG gun. The nozzle utilizes a slip-on connection mechanism, which simplifies maintenance by allowing the operator to quickly remove the nozzle for spatter cleaning or contact tip replacement without the need for threading or tools.

This nozzle is part of the Tweco 24 Series and is specifically designed to fit Tweco No. 4 (400 Amp) and No. 5 (500 Amp) air-cooled MIG guns. It works in conjunction with standard 34A or 34CT insulators to ensure proper electrical isolation. Whether used in shipyards, structural steel fabrication, or heavy equipment manufacturing, the Tweco 1244-1030 delivers the reliability and performance professional welders demand.
