The nozzle measures 3.219 inches in length with a 0.062 inch bore and 0.875 inch outer diameter. It uses a 9\/16 inch-18 UNC-2B thread to mount directly onto the conductor tube assembly. 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 made from silicone. The part number is roll-stamped on the outer surface for fast field identification. Sold as a 2-pack.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is designed for use with standard gas diffusers in MIG welding setups where reliable shielding gas coverage and tip protection are required. The silicone insulator provides electrical isolation from the gas diffuser without requiring a separate insulator component. The recess contact tip relationship of 0.125 to 0.156 inches suits demanding weld cycles in fabrication, structural, and manufacturing environments. Licensed welders and certified welding technicians working with wire-feed MIG guns in medium to heavy industrial applications are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-piece design: copper alloy housing, solid brass insert, silicone insulator — no additional insulator needed\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 copper alloy tubing for heat resistance and conductivity\u003c\/li\u003e\n  \u003cli\u003eSilicone nozzle insulator provides electrical insulation from the gas diffuser\u003c\/li\u003e\n  \u003cli\u003ePart number roll-stamped on outer surface for easy identification during service\u003c\/li\u003e\n  \u003cli\u003eSold as 2 per pack\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 guns rated for medium to heavy duty applications up to 450 amps.\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 gun before removing or installing nozzle components. Thread the nozzle onto the conductor tube assembly by hand until snug, then verify the insulator is properly seated to maintain electrical isolation from the gas diffuser. Inspect the nozzle insert threads and insulator for wear or spatter buildup before reinstalling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Weldskill 23\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 450 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 0.062 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\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\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\u003ePack Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\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: 1230-1017\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51347803439410,"sku":"1230-1017","price":26.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545928.jpg?v=1782114126","url":"https:\/\/voomisupply.com\/products\/tweco-1230-1017-mig-welding-nozzle-450a-3-219-inch-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
