OVERVIEW

Tweco 24A-100-FAS Flat Arc Spot Nozzle Overview

The Tweco 24A-100-FAS is a specialized MIG welding nozzle designed specifically for arc spot welding applications. Sold in a convenient pack of two, these nozzles are engineered to provide the consistency and durability required for repetitive spot welding tasks. Unlike standard conical or cylindrical nozzles, the 24A-100-FAS features a flat end that allows the operator to press the gun flush against the base metal. This design eliminates the guesswork in maintaining the correct nozzle-to-work distance (stick-out), ensuring that every spot weld is uniform in size and penetration.

Manufactured from high-quality copper alloy, this nozzle offers excellent thermal conductivity and resistance to spatter adhesion, which is critical in high-volume welding environments. It is part of the popular Tweco 24 Series, making it compatible with a wide range of industry-standard MIG guns, including the Tweco Spray Master and Professional No. 2, 3, and 4 series. The slip-on design ensures a secure fit over the gas diffuser while allowing for rapid removal for cleaning or replacement.

Whether you are working in automotive repair, HVAC fabrication, or general light-gauge manufacturing, the Tweco Flat Arc Spot Nozzle is an indispensable tool for achieving professional results. By standardizing the standoff distance, it reduces operator fatigue and minimizes defects associated with inconsistent arc lengths. Trust genuine Tweco consumables to maintain the performance and reliability of your welding equipment.

FAQ

This nozzle fits Tweco MIG guns that use the 24 Series consumables, including the Spray Master 250, 350, and 450, as well as the Professional No. 2, 3, and 4 guns.

The flat end allows the nozzle to be pressed flush against the workpiece, ensuring a consistent standoff distance and arc length for uniform spot welds.

This package contains 2 (two) Tweco 24A-100-FAS Flat Arc Spot Nozzles.

This is a slip-on nozzle designed to fit over standard Tweco 24 series gas diffusers (like the 52 or 52-23 series).

It is made of a heavy-duty copper alloy designed to withstand high heat and resist spatter.

While physically possible, it is designed specifically for spot welding. The flat end and bore shape are optimized for stationary spots rather than moving weld puddles, so visibility and gas coverage for continuous welds might be limited compared to standard conical nozzles.

The Tweco stock number is 1240-1550.

No, it uses the standard gas diffusers compatible with the 24 Series nozzle line.
