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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated up to 450 amps for medium to heavy duty welding applications\u003c\/li\u003e\n\u003cli\u003e3-piece design: copper alloy housing, solid brass insert, silicone insulator\u003c\/li\u003e\n\u003cli\u003eNozzle insert machined to match conductor tube OD threads for direct thread-on installation\u003c\/li\u003e\n\u003cli\u003eSilicone insulator provides electrical isolation from the gas diffuser without a separate insulator\u003c\/li\u003e\n\u003cli\u003ePart number rolled and stamped on outer surface for easy identification\u003c\/li\u003e\n\u003cli\u003eSold as 2 per pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement nozzle for standard gas diffuser assemblies in the Tweco Weldskill 23 Series MIG gun platform.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation 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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Weldskill 23\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 450 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 1\/5 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16 inch-18 UNC-2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlush Contact Tip Relationship\u003c\/strong\u003e: 0.125 to 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Copper alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulator Material\u003c\/strong\u003e: Silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign\u003c\/strong\u003e: 3-piece\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.21 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246287775\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TWECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1230-1016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51347012190514,"sku":"1230-1016","price":45.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545932.jpg?v=1782096463","url":"https:\/\/voomisupply.com\/products\/tweco-1230-1016-mig-welding-nozzle-450a-23-series","provider":"Voomi Supply","version":"1.0","type":"link"}
