OVERVIEW

Tweco 23H62 Standard Slip-On Nozzle (Pack of 2)

Optimize your MIG welding setup with the Tweco 23H62 Standard Nozzle, a premium replacement part designed for the rigorous demands of industrial welding. This nozzle is part of the renowned Tweco 23 Series, specifically engineered for use with Tweco Classic #3, #4, and #5 MIG guns, as well as many other compatible 300A to 500A welding torches. The 23H62 features a 5/8-inch (15.9 mm) bore orifice, making it the versatile choice for a wide range of wire diameters and transfer modes, including short-circuit and spray transfer.

The nozzle utilizes a slip-on connection mechanism that works in conjunction with a 34 or 54 series gas diffuser (and appropriate nozzle insulator). This design eliminates the frustration of cross-threading and allows for rapid disassembly when troubleshooting wire feed issues or replacing contact tips. The heavy-duty copper construction ensures excellent thermal conductivity, keeping the front-end consumables cooler and extending their operational life. Additionally, the robust wall thickness helps maintain the nozzle's structural integrity even when subjected to the accidental knocks and drops common in busy welding environments.

Welders Supply provides this essential consumable in a convenient pack of two, offering excellent value for high-volume shops. The 23H62 is designed to maintain a consistent gas envelope around the weld pool, which is critical for achieving X-ray quality welds. The integrated electrical insulation provides a safety barrier, preventing arc-out on the nozzle itself. Upgrade your torch maintenance routine with genuine Tweco-style performance and reliability.

FAQ

The Tweco 23H62 nozzle has a 5/8-inch (0.625 inch or 15.9 mm) bore diameter, which is the standard size for most general-purpose MIG welding applications.

The 23H62 is a slip-on nozzle. It is designed to slide over the nozzle insulator and gas diffuser, held in place by friction and a retaining spring or ring, rather than screwing on.

This nozzle is compatible with Tweco Classic #3, #4, and #5 series MIG guns, as well as many other Tweco-style guns rated for 300 to 500 amps.

This product (SKU 12301220) is a package of 2 nozzles.

The 'H' stands for 'Heavy Duty'. This indicates the nozzle has thicker copper walls compared to standard duty nozzles, allowing it to withstand higher heat and amperages.

Yes, slip-on nozzles like the 23H62 typically require a specific nozzle insulator (often part number 34A or similar) to sit correctly on the conductor tube and hold the nozzle in place.

While you can physically use it, flux-cored welding (FCAW-S) often does not require a gas nozzle. However, for gas-shielded flux core (FCAW-G), this nozzle is perfectly suitable.
