The nozzle threads directly onto the conductor tube assembly, eliminating the need for a separate insulator. It features a 3\/4 inch bore and a 9\/16 inch-18 UNC-2B thread size, making it suitable for applications that require longer electrical stick-out or where the nozzle may contact the workpiece. Constructed from 122 DHP copper alloy, this nozzle delivers reliable conductivity and durability under sustained high-amperage welding conditions. Sold in a 2-pack.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is built for heavy-duty MIG welding environments where sustained amperages up to 450 A are common, such as structural fabrication, heavy equipment repair, and industrial manufacturing. The self-insulated design suits applications where the nozzle threads into the conductor tube and electrical isolation from the gas diffuser is handled internally by the nozzle insulator. It is a standard fitment for TWECO 23 Series gun assemblies used by professional welding technicians in shop and field settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated for heavy-duty welding applications up to 450 amps\u003c\/li\u003e\n  \u003cli\u003e3-piece design: copper alloy nozzle housing, solid brass nozzle insert, and silicone nozzle insulator\u003c\/li\u003e\n  \u003cli\u003eSelf-insulated construction eliminates the need for an additional separate insulator\u003c\/li\u003e\n  \u003cli\u003eNozzle insert machined from solid brass with internal threads matched to conductor tube OD threads\u003c\/li\u003e\n  \u003cli\u003eNozzle housing cut and formed from 122 DHP copper alloy tubing for high conductivity\u003c\/li\u003e\n  \u003cli\u003ePart number roll-stamped on the outer surface for quick field identification\u003c\/li\u003e\n  \u003cli\u003e9\/16 inch-18 UNC-2B thread size for extended electrical stick-out or contact-tip-to-work applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TWECO 23 Series standard gas diffusers and conductor tube assemblies where the nozzle threads directly onto the conductor tube.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified welding technicians. Disconnect and de-energize the welding power source before replacing any gun consumables. Thread the nozzle onto the conductor tube assembly by hand until snug, taking care not to cross-thread the UNC-2B threads. Inspect the nozzle insulator for cracking or spatter buildup during routine maintenance and replace the nozzle as a unit when wear affects arc performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 3\/4 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\u003eMaximum Amperage\u003c\/strong\u003e: 450 A\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: Silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDesign\u003c\/strong\u003e: 3-piece self-insulated\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: 0.36 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246056791\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: 1230-1230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344590864690,"sku":"1230-1230","price":57.02,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545910.jpg?v=1782037241","url":"https:\/\/voomisupply.com\/products\/tweco-1230-1230-welding-nozzle-3-4-inch-bore-450a","provider":"Voomi Supply","version":"1.0","type":"link"}
