12401501 - Tweco 24A-62 Conical Nozzle 5/8 Bore Slip-On

Technical Specification: Tweco 1240-1501 (24A-62)

The Tweco 1240-1501, industry reference 24A-62, is a standard-duty conical gas nozzle designed for the Tweco 24 Series consumable system. Engineered for professional industrial applications, this nozzle features a 5/8-inch (16mm) bore diameter, which is the industry standard for medium-to-heavy duty MIG (GMAW) and Flux-Cored (FCAW) welding operations. The nozzle has an overall length of 2.34 inches (59.5mm) and utilizes a slip-on connection mechanism, relying on the friction fit over a compatible gas diffuser (typically the 54A or 34A series) to maintain position.

Manufactured from a high-conductivity copper alloy, the nozzle is designed to efficiently dissipate thermal energy generated during the welding arc, prolonging the service life of the front-end consumables. The internal construction includes a high-temperature resistant insulator that electrically isolates the outer copper shell from the electrically live contact tip and diffuser. This insulation is critical for preventing arc-out or short-circuiting should the nozzle inadvertently contact the grounded workpiece during operation.

The conical geometry of the 24A-62 is specifically optimized to reduce the nozzle's profile at the exit point, thereby increasing the welder's line of sight to the arc and the weld puddle without compromising the laminar flow of the shielding gas. This unit is rated for use with Tweco Classic Number 3 and Number 4 MIG guns, as well as the Spray Master series and other IEC-standard guns utilizing Tweco-style front-end parts. It is suitable for amperage ranges typically between 300 and 400 amps.
