407741 - Tweco 24A-62 MIG Gun Nozzle, 5/8 Inch Bore, Slip-On

Precision Gas Coverage for Quality Welds

The Tweco 407741 (Model 24A-62) is a premium slip-on MIG nozzle designed to deliver superior shielding gas coverage for Gas Metal Arc Welding (GMAW). Engineered with a 5/8-inch (15.9 mm) orifice, this nozzle strikes the perfect balance between gas flow velocity and coverage area, making it the standard choice for a wide range of welding amperages and joint configurations. Proper gas shielding is critical to preventing atmospheric contamination, and the 24A-62 ensures a laminar flow that effectively protects the molten weld pool from nitrogen and oxygen absorption, thereby reducing the risk of porosity and weld defects.

Constructed from a high-conductivity copper alloy, the nozzle is built to dissipate heat rapidly, prolonging the service life of the consumable even under high-duty cycle conditions. The thermal properties of the copper also help in minimizing the adhesion of molten spatter, allowing for easier cleaning and maintenance. This nozzle is part of the renowned Tweco 24 Series, widely recognized for its reliability and performance in industrial environments. It is designed to fit seamlessly with Tweco Professional No. 2, No. 3, and No. 4 guns, as well as the Spray Master series, ensuring broad compatibility across your equipment fleet.

The slip-on connection mechanism is a key feature for operational efficiency. Unlike threaded nozzles that can seize due to thermal expansion or spatter buildup, the slip-on design allows the welder to remove the nozzle quickly for cleaning or contact tip replacement. It fits snugly over the nozzle insulator, maintaining concentricity with the contact tip for consistent arc performance. Whether you are welding mild steel, stainless steel, or aluminum, the Tweco 24A-62 provides the durability and precision required for high-quality fabrication.

Key Technical Benefits:

• Optimal Bore Size: 5/8" diameter supports standard gas flow rates (25-35 CFH) for effective shielding.
• Thermal Management: Heavy-wall copper construction withstands radiant heat from the arc.
• Electrical Isolation: Works in conjunction with the gas diffuser and insulator to prevent shorting to the workpiece.
