12401423 - Tweco 24CT-62-R MIG Nozzle, 5/8" Bore, Recessed, Coarse Thread (2-Pack)

Tweco 24CT-62-R Standard MIG Nozzle (2-Pack)

The Tweco 24CT-62-R (Stock No. 1240-1423) is a high-performance standard MIG nozzle designed for professional welding applications. Engineered by ESAB under the renowned Tweco brand, this nozzle is a critical component for maintaining efficient gas shielding and arc stability in medium to heavy-duty fabrication environments. This package contains two (2) genuine Tweco nozzles.

Technical Specifications

This nozzle features a 5/8-inch (15.9 mm) bore, which is the industry standard for a wide range of amperage settings and wire diameters. The "CT" in the part number stands for Coarse Thread, a robust threading design that resists cross-threading and seizing, ensuring that the nozzle can be easily removed for cleaning or replacement even after exposure to intense welding heat. The "R" designation indicates a Recessed tip relationship, where the contact tip sits slightly back inside the nozzle. This configuration is ideal for higher current applications as it helps prevent the contact tip from shorting against the workpiece and improves shielding gas coverage in drafty conditions.

Compatibility and Construction

Manufactured from a durable copper alloy, the 24CT-62-R is built to withstand the thermal stresses of continuous welding. It is fully compatible with Tweco Spray Master series guns (350 and 450 Amp models) as well as the classic Tweco Professional No. 4 and No. 5 MIG guns. It threads securely onto the 34CT or 54CT gas diffusers/insulators.

Key Features

• Bore Size: 0.625" (5/8") for optimal gas flow.
• Thread Style: Coarse Thread for quick maintenance.
• Tip Position: Recessed (1/8" to 1/4" depending on setup) for tip protection.
• Durability: Heavy-wall copper construction resists deformation.
