Tweco 1230-1016 Mig Welding Nozzle 450A 23 Series

Product Description

The TWECO 1230-1016 is a Weldskill 23 Series MIG welding nozzle built for standard gas diffuser configurations in medium to heavy duty welding applications. Rated up to 450 amps, it features a 3-piece construction: a nozzle housing cut and formed from copper alloy tubing, a nozzle insert machined from solid brass, and a nozzle insulator constructed of silicone material. The bore size is 1/5 inch with a 9/16 inch-18 UNC-2B thread size and a flush contact tip relationship of 0.125 to 0.156 inches. The part number is rolled and stamped on the outer surface for quick field identification. Sold in a pack of 2.

This nozzle is designed for medium to heavy duty MIG welding environments where consistent shielding gas coverage is critical to weld quality and gun longevity. The silicone insulator provides electrical isolation from the gas diffuser without requiring an additional separate insulator, simplifying assembly. The brass nozzle insert is machined to accept internal threads that match the conductor tube OD threads, allowing the nozzle to thread directly onto the conductor tube assembly. It is well suited for fabrication shops, structural welding, and industrial manufacturing settings where higher amperage output is routine.

Key Features

• Rated up to 450 amps for medium to heavy duty welding applications
• 3-piece design: copper alloy housing, solid brass insert, silicone insulator
• Nozzle insert machined to match conductor tube OD threads for direct thread-on installation
• Silicone insulator provides electrical isolation from the gas diffuser without a separate insulator
• Part number rolled and stamped on outer surface for easy identification
• Sold as 2 per pack

Compatibility

Designed as an OEM-style replacement nozzle for standard gas diffuser assemblies in the Tweco Weldskill 23 Series MIG gun platform.

Installation Notes

Installation and replacement should be performed by a qualified welding technician or trained professional. Disconnect and de-energize the welding system completely before servicing the nozzle or any gun components. Thread the nozzle directly onto the conductor tube assembly by hand until snug, taking care not to cross-thread the brass insert. Allow the nozzle to cool fully before handling after welding operations.
