It features a 3\/8-inch (0.375 inch) bore and measures 3.219 inches in length with a 3\/4-inch OD. The nozzle threads directly onto the conductor tube assembly and is constructed from a copper alloy housing, a solid brass insert, and a silicone insulator in a 3-piece design. The part number is rolled-stamped on the outer surface for fast field identification. Sold in a 2-pack, this nozzle is installed by professional welders and MIG gun technicians working with Tweco No. 3 MIG guns in industrial and fabrication environments.\u003c\/p\u003e\u003cp\u003eThe 1230-1035 is designed for use with Tweco No. 3 MIG guns rated up to 450 amps. It is suited for medium to heavy-duty MIG welding operations where reliable gas shielding and electrical insulation are required. The nozzle insert is machined with internal threads that match the conductor tube OD threads, allowing a secure threaded connection to the conductor tube assembly. The silicone nozzle insulator provides the electrical insulation needed to separate the nozzle from the gas diffuser. Thread size is 9\/16-18 UNC-2B. Recess contact tip relationship is 0.125 to 0.156 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-inch bore with 3.219-inch length and 3\/4-inch OD for heavy-duty MIG applications up to 450A\u003c\/li\u003e\n\u003cli\u003e3-piece design: copper alloy housing, solid brass insert, and silicone insulator — no additional insulator required\u003c\/li\u003e\n\u003cli\u003eNozzle insert machined to match conductor tube OD threads for a secure threaded fit\u003c\/li\u003e\n\u003cli\u003eSilicone nozzle insulator provides electrical insulation from the gas diffuser\u003c\/li\u003e\n\u003cli\u003ePart number rolled-stamped on outer surface for easy identification in the field\u003c\/li\u003e\n\u003cli\u003eSold as a 2-pack per unit of measure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Tweco No. 3 MIG guns rated up to 450 amps.

Disconnect and de-energize the welding power source before servicing any nozzle or gun components. Thread the nozzle onto the conductor tube assembly by hand first, then verify a secure fit before resuming welding operations. Inspect the silicone insulator for damage during each replacement to ensure proper electrical isolation from the gas diffuser.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 0.375 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: 0.75 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\u003eRecess Contact Tip Relationship\u003c\/strong\u003e: 0.125 to 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 450 amps\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\u003ePackage Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 1230-1035\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51342977597746,"sku":"1230-1035","price":60.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545929.jpg?v=1782012564","url":"https:\/\/voomisupply.com\/products\/tweco-1230-1035-mig-nozzle-3-8-in-bore-450a-copper-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
