12601713 - Tweco MA2462 Pulsemaster MIG Nozzle 5/8 Inch Bore

Reliable Gas Coverage for Pulsemaster Guns

The Tweco MA2462 (Stock No. 1260-1713) is a premium air-cooled nozzle engineered specifically for the Tweco Pulsemaster series of MIG welding guns. In the demanding world of industrial fabrication, maintaining consistent shielding gas coverage is critical for weld quality. This nozzle features a 5/8-inch (0.625") bore, which is the industry standard for general-purpose MIG welding, providing a balanced gas envelope that protects the molten weld pool from atmospheric contamination.

Manufactured from high-grade copper alloy, the MA2462 is designed to withstand the intense heat cycles typical of air-cooled welding applications. The material's superior thermal conductivity helps dissipate heat away from the front end of the gun, prolonging the life of both the nozzle and the contact tip inside. Its robust construction also resists the adhesion of weld spatter, making it easier to clean and maintain during long shifts. Whether you are welding mild steel, stainless, or aluminum, this genuine Tweco component ensures your equipment operates at peak efficiency.

Proper maintenance of your MIG gun's front-end consumables is essential for preventing porosity and ensuring smooth wire feeding. The Tweco MA2462 fits securely onto Pulsemaster diffusers/insulators, ensuring a tight gas seal and electrical isolation where required. By choosing genuine Tweco parts, you guarantee compatibility and performance that matches the original specifications of your welding equipment.
