It features a 1\/2 inch bore, a 3.11 inch length, and a 0.875 inch OD. The thread size is 9\/16 inch-18 UNC-2B, and the flush contact tip relationship is 0.062 inches, making it suited for applications requiring longer electrical stick-out. This nozzle strings into the conductor tube assembly and is designed for use with standard gas diffusers. Sold in packs of 2, the part number is rolled-stamped on the outer surface for quick field identification.\u003c\/p\u003e\u003cp\u003eThis nozzle is intended for heavy-duty MIG welding environments where sustained high-amperage output is required. The flush tip configuration brings the contact tip closer to the work piece and is typically selected for applications with shorter or tighter arc lengths. It is well suited for industrial fabrication, structural welding, and other demanding applications where the gun assembly sees sustained high-cycle use. Licensed welders and welding technicians are the primary installers and users of this consumable.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-piece design: nozzle housing, nozzle insert, and nozzle insulator — no additional insulator required\u003c\/li\u003e\n\u003cli\u003eNozzle housing cut and formed from 122 DHP copper alloy tubing for high thermal conductivity\u003c\/li\u003e\n\u003cli\u003eNozzle insert machined from solid brass with internal threads machined to match conductor tube OD threads\u003c\/li\u003e\n\u003cli\u003eNozzle insulator constructed of G7 silicone material for electrical insulation from the gas diffuser\u003c\/li\u003e\n\u003cli\u003ePart number rolled-stamped on outer surface for easy identification during inventory and replacement\u003c\/li\u003e\n\u003cli\u003eRated for heavy-duty welding up to 450 amps\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard gas diffusers and conductor tube assemblies in the TWECO 23 Series MIG gun platform.

Ensure the conductor tube threads are clean and free of spatter before threading on the replacement nozzle. Do not overtighten — hand-thread until snug to avoid damage to the brass insert threads. Follow all applicable AWS safety guidelines and facility hot-work procedures when servicing welding equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Length\u003c\/strong\u003e: 3.11 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\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: 0.062 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 450 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Housing Material\u003c\/strong\u003e: 122 DHP 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: G7 silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.21 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246056579\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: 1230-1112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51345134584114,"sku":"1230-1112","price":72.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545951.jpg?v=1782049960","url":"https:\/\/voomisupply.com\/products\/tweco-1230-1112-mig-nozzle-1-2-in-bore-450a-23-series","provider":"Voomi Supply","version":"1.0","type":"link"}
