OVERVIEW

Tweco 24AH-75 MIG Gun Nozzle - 3/4" Bore (2-Pack)

Keep your Tweco No. 4 or Spray Master MIG gun running at peak performance with the genuine Tweco 24AH-75 nozzle. Known in the industry as the standard for heavy-duty welding, this nozzle features a wide 3/4-inch bore that delivers a broad umbrella of shielding gas. This is essential when you are cranking up the amps for thick plate welding or running hot spray transfer arcs, ensuring your weld pool remains protected from atmospheric contamination.

Key Benefits for the Welder:

  • Superior Durability: Made from robust copper alloy, this nozzle resists spatter adhesion and stands up to the abuse of industrial environments.
  • Easy Adjustment: The slip-on design means no threads to seize up. You can quickly pull the nozzle off to clean out spatter or change your tip, and slide it back on to your preferred recess depth.
  • Perfect Fit: Designed specifically for the Tweco 34A insulator found on No. 4 and Spray Master 450 guns, ensuring a tight, leak-free fit every time.

Don't compromise your weld quality with inferior generic parts. This 2-pack of 1240-1230 nozzles gives you the reliability of the Tweco brand, helping you reduce downtime and produce cleaner, stronger welds. Ideal for fabrication shops, shipyards, and heavy equipment repair.
