The nozzle features a 3\/8 inch bore, measures 2.224 inches in length with a 3\/4 inch OD, and is constructed from 122 DHP copper alloy tubing for reliable performance in higher-heat welding environments. Its 3-piece design integrates a copper alloy nozzle housing, a solid brass nozzle insert with machined internal threads, and a G7 silicone nozzle insulator that provides electrical separation from the gas diffuser without requiring an additional insulator component. The part number is rolled-stamped on the outer surface for quick field identification. Sold as a 2-pack.\u003c\/p\u003e\u003cp\u003eThis nozzle is suited for light to medium duty MIG welding applications drawing up to 180 amps. The recessed contact tip relationship of 0.125 to 0.156 inches makes it a practical choice for higher-heat work requiring longer electrical stick-out, as well as tack, spot, and stitch welding passes where the nozzle may contact the workpiece. It threads directly onto a standard gas diffuser compatible with Tweco No. 1 MIG gun front-end assemblies. The M11-1.5-6H thread size ensures a secure, repeatable fit during gun assembly and front-end maintenance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e122 DHP copper alloy housing cut and formed from tubing for high-heat durability\u003c\/li\u003e\n\u003cli\u003eSolid brass nozzle insert with machined internal threads to match gas diffuser\u003c\/li\u003e\n\u003cli\u003eG7 silicone nozzle insulator provides electrical insulation without an additional insulator part\u003c\/li\u003e\n\u003cli\u003e3\/8 inch bore with 3\/4 inch OD and 2.224 inch length\u003c\/li\u003e\n\u003cli\u003eRecessed tip relationship of 0.125 to 0.156 inches for longer stick-out applications\u003c\/li\u003e\n\u003cli\u003ePart number rolled-stamped on outer surface for easy identification during inventory and install\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Tweco No. 1 MIG guns rated up to 180 amps using a standard gas diffuser with M11-1.5-6H thread sizing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by welding technicians during front-end assembly or routine consumable replacement on MIG guns. Always de-energize and disconnect the MIG gun from the wire feeder before removing or installing nozzle components. Thread the nozzle onto the gas diffuser by hand first to avoid cross-threading the brass insert, then snug with appropriate pliers — do not over-tighten, as this can crack the silicone insulator. Inspect the nozzle insulator and insert for spatter buildup or cracking during each consumable change interval.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Length\u003c\/strong\u003e: 2.224 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 180 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M11-1.5-6H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Recess\u003c\/strong\u003e: 0.125 to 0.156 inches\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 Weight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246055794\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: 1210-1300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346344116530,"sku":"1210-1300","price":85.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545903.jpg?v=1782077958","url":"https:\/\/voomisupply.com\/products\/tweco-1210-1300-mig-nozzle-3-8-inch-bore-180a-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
