OVERVIEW

Precision Spot Welding with Tweco 24A-37-SS

For welders engaged in automotive bodywork, sheet metal fabrication, or any application requiring repetitive arc spot welds, the Tweco 24A-37-SS Flat Arc Spot Nozzle is an essential accessory. Unlike standard tapered or recessed nozzles, this specialized component features a completely flat end. This design allows the operator to press the MIG gun nozzle directly and flush against the workpiece, ensuring a consistent standoff distance and perpendicular alignment every single time. This stability is crucial for producing uniform spot welds that are strong and visually clean.

The nozzle features a 3/8-inch (9.5 mm) bore, which is optimized for the gas flow requirements of spot welding, minimizing turbulence and ensuring the weld pool is adequately shielded during the short duration of the arc. As part of the renowned Tweco 24 Series, this nozzle utilizes an adjustable slip-on connection mechanism. This allows it to fit securely over the gas diffuser of Tweco Professional No. 3 and No. 4 guns, as well as Spray Master 350 and 450 series guns. The adjustable nature means you can fine-tune the nozzle position relative to the contact tip, although for spot welding, the tip is typically recessed significantly.

Durability is key in industrial environments, and Tweco delivers with high-quality copper alloy construction. This material choice ensures excellent heat dissipation, preventing the nozzle from overheating during rapid-fire spot welding sequences. This package contains two (2) nozzles, providing excellent value and ensuring you have a backup ready when needed. Whether you are repairing a classic car chassis or fabricating metal cabinets, these spot nozzles transform your standard MIG gun into a specialized spot welding tool.

  • Specialized Design: Flat face for flush contact with the workpiece.
  • Optimal Fit: Designed for Tweco #3, #4, and Spray Master guns.
  • Quality Material: Heavy-duty copper alloy resists spatter adhesion and heat buildup.
  • Convenient Pack: Includes two nozzles per package.

FAQ

The flat end allows the operator to press the nozzle flush against the workpiece, ensuring the gun is steady and the distance from the tip to the metal is constant, which is essential for consistent spot welds.

This nozzle fits Tweco Professional Series No. 3 and No. 4 guns, as well as Tweco Spray Master 350 and 450 series guns that use 24 Series consumables.

The bore size is 3/8 inch (0.375 inches or 9.5 mm).

This is an adjustable slip-on nozzle. It slides over the gas diffuser and is held in place by friction, allowing you to adjust the nozzle position.

This product (SKU 12401101) is sold as a package of 2 nozzles.

While you can, the flat end and smaller 3/8" bore are optimized for spot welding. For general welding, a tapered nozzle with a larger bore might provide better visibility and gas coverage for moving puddles.

It uses the standard 24 Series insulator (often part number 34A) found on Tweco No. 3 and No. 4 guns.

In this context, 'SS' typically stands for Spot/Stitch or Short Stop, indicating its design for spot welding applications.
