The nozzle features a 5\/8-inch (0.625 inch) bore, a 3.219-inch length, and a 0.875-inch outer diameter. Construction follows a 3-piece design: 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 silicone insulator provides the electrical insulation required from the gas diffuser without requiring an additional separate insulator. The part number is rolled and stamped on the outer surface for fast field identification. Sold as 2 per pack.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is designed for use with standard gas diffusers on medium to heavy duty MIG welding guns rated up to 450 amps. The 9\/16-inch 18 UNC-2B internal thread matches the conductor tube assembly, and the nozzle insert is machined to match conductor tube OD threads. The recessed contact tip relationship measures 0.125 to 0.156 inches. It is suited for professional welding environments where consistent shielding gas coverage and long consumable life are priorities. Licensed welders and fabrication shops handling structural or heavy plate work are the primary end users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-inch (0.625 inch) bore size designed for standard gas diffuser compatibility\u003c\/li\u003e\n  \u003cli\u003e3-piece design: copper alloy housing, solid brass insert, silicone insulator — no additional insulator required\u003c\/li\u003e\n  \u003cli\u003eRated up to 450 amps for medium to heavy duty welding applications\u003c\/li\u003e\n  \u003cli\u003ePart number rolled and stamped on outer surface for easy identification in the field\u003c\/li\u003e\n  \u003cli\u003eNozzle threads directly onto the conductor tube assembly via 9\/16-inch 18 UNC-2B threads\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-per-pack quantity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard gas diffusers on Tweco Weldskill 23 Series MIG welding gun assemblies rated for medium to heavy duty applications up to 450 amps.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified welder or welding equipment technician. Disconnect and de-energize the welding machine before replacing consumables. Thread the nozzle onto the conductor tube assembly by hand until snug, taking care not to cross-thread the UNC-2B internal threads. Inspect the silicone insulator for damage during each consumable change to maintain proper electrical insulation from the gas diffuser.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Length\u003c\/strong\u003e: 3.219 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 450 amps\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\u003eRecess Contact Tip Relationship\u003c\/strong\u003e: 0.125 to 0.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Housing Material\u003c\/strong\u003e: Copper alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Insert Material\u003c\/strong\u003e: Solid brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Insulator 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\u003eWeight\u003c\/strong\u003e: 0.22 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246287782\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1230-1012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344001892658,"sku":"1230-1012","price":35.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545934.jpg?v=1782026524","url":"https:\/\/voomisupply.com\/products\/tweco-1230-1012-mig-welding-nozzle-5-8-inch-bore-450a-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
