It measures 3.25 inches in length with a 3\/4-inch bore and a 0.875-inch outer diameter. Rated for use in medium to heavy-duty welding applications up to 450 amps, this nozzle is constructed from 122 DHP copper alloy tubing and features a recessed contact tip relationship of 0.125 to 0.156 inches. The part number is rolled-stamped on the exterior surface for quick field identification. Sold as a 2-pack.\u003c\/p\u003e\n\u003cp\u003eThis nozzle fits welding applications ranging from medium fabrication to heavy industrial work where higher amperage output is required. The recessed contact tip design makes it well suited for high-heat passes, tack welds, spot welds, and stitch welding scenarios where the nozzle may contact the workpiece. It is intended for use on MIG guns equipped with the standard EL series gas diffuser. Licensed welding technicians and certified welders are the primary installers in both shop and field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-piece design: nozzle housing, nozzle insert, and nozzle insulator — no additional insulator required\u003c\/li\u003e\n  \u003cli\u003eHousing cut and formed from 122 DHP copper alloy tubing for thermal conductivity and durability\u003c\/li\u003e\n  \u003cli\u003eNozzle insert machined from solid brass with internal threads matched to the EL gas diffuser\u003c\/li\u003e\n  \u003cli\u003eG7 silicone nozzle insulator provides electrical isolation from the gas diffuser\u003c\/li\u003e\n  \u003cli\u003eRecessed tip contact relationship (0.125 to 0.156 inches) suited for high-heat and contact-nozzle welding\u003c\/li\u003e\n  \u003cli\u003ePart number rolled-stamped on external surface for fast identification in multi-nozzle inventory\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 the standard TWECO EL series gas diffuser.

Always power down the welding machine and allow the gun to cool completely before removing or installing nozzle components. Ensure the gas diffuser threads are clean and undamaged before threading on the nozzle insert to prevent cross-threading. Inspect the silicone insulator for cracking or heat damage at each nozzle change interval.\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\u003eNozzle Length\u003c\/strong\u003e: 3.25 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\u003eAmperage Rating\u003c\/strong\u003e: 450 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Tip Recess\u003c\/strong\u003e: 0.125 to 0.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Coarse threaded\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\u003eWeight\u003c\/strong\u003e: 0.22 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246138756\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: 1260-1653\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344391569714,"sku":"1260-1653","price":40.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546041.jpg?v=1782034845","url":"https:\/\/voomisupply.com\/products\/tweco-1260-1653-mig-welding-nozzle-3-4-in-bore-450a","provider":"Voomi Supply","version":"1.0","type":"link"}
