Maximize the versatility of your MIG welding equipment with the Tweco 24A-37-SS (Stock Code: 1240-1101). This nozzle is a specialized variant of the standard 24 Series adjustable slip-on nozzle, engineered specifically for Gas Metal Arc Spot Welding (GMASW). The defining feature of this unit is its "SS" or Spot/Stitch design, which culminates in a flat, non-tapered face. This geometry enables the welder to rest the nozzle directly on the base metal, stabilizing the gun and maintaining a fixed contact-tip-to-work distance (CTWD), which is critical for consistent spot weld penetration and diameter.
With a 3/8-inch (9.5 mm) bore, the 24A-37-SS provides a focused gas column ideal for the localized heating of spot welds. It is rated for use with standard Tweco gas diffusers and insulators found on Tweco Professional No. 3 (300A) and No. 4 (400A) air-cooled MIG guns. It is also fully compatible with the Tweco Spray Master 350 and 450 series. The slip-on fit relies on the friction provided by the gas diffuser's O-ring or spring, allowing for quick removal for cleaning spatter or replacing contact tips.
Manufactured from electrical-grade copper alloy, the nozzle withstands the intense radiant heat generated during the spot welding process. The wall thickness is designed to endure the mechanical stress of being pressed against workpieces repeatedly. This product is supplied as a pack of 2, making it a cost-effective addition to your consumables inventory. For shops performing stitch welding or plug welding on thin-gauge materials, this nozzle provides the mechanical guide needed for professional results without the need for complex fixturing.
