The nozzle features a 3\/4-inch bore and measures 3.219 inches in length. It threads directly into the conductor tube assembly via a 9\/16-18 UNC-2B thread and maintains a recessed contact tip relationship of 0.125 to 0.156 inches. Built from a copper alloy housing with a solid brass insert and a silicone nozzle insulator, this is a purpose-built component for demanding, high-amperage MIG welding operations. The part number is rolled and stamped on the outer surface for quick field identification. Sold as a 2-pack.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is suited for heavy-duty MIG welding applications in fabrication, manufacturing, and structural welding environments. The flat arc spot design makes it appropriate for spot welding configurations. It is installed by professional welding technicians and MIG gun service personnel working with Tweco No. 3 gun assemblies in applications requiring sustained output up to 450 amps.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlat arc spot nozzle design for spot welding applications\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch bore with 9\/16-18 UNC-2B thread, strings directly into the conductor tube assembly\u003c\/li\u003e\n  \u003cli\u003e3-piece construction: 122 DHP copper alloy housing, solid brass machined insert, and G7 silicone insulator\u003c\/li\u003e\n  \u003cli\u003eNozzle insert is internally threaded to match conductor tube OD threads, no additional insulator required\u003c\/li\u003e\n  \u003cli\u003eG7 silicone nozzle insulator provides electrical insulation from the gas diffuser\u003c\/li\u003e\n  \u003cli\u003ePart number rolled and stamped on outer surface for easy identification in the field\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Tweco No. 3 MIG guns rated up to 450 amps.

Disconnect and de-energize the welding power source completely before servicing the gun or replacing nozzle components. Thread the nozzle into the conductor tube assembly by hand first to confirm proper thread engagement before final tightening. Inspect the silicone insulator and brass insert for wear or damage each time the nozzle is replaced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Flat Arc Spot\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Length\u003c\/strong\u003e: 3.219 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-18 UNC-2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Tip Relationship (Recess)\u003c\/strong\u003e: 0.125 to 0.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 450 A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: 122 DHP 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: 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: 0.24 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.9 inches\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: 1230-530\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346780455218,"sku":"1230-530","price":55.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545940.jpg?v=1782090131","url":"https:\/\/voomisupply.com\/products\/tweco-1230-530-mig-nozzle-flat-arc-spot-3-4-inch-bore-450a","provider":"Voomi Supply","version":"1.0","type":"link"}
