Built with a 3-piece construction, it consists of a nozzle housing cut and formed from 122 DHP copper alloy tubing, a nozzle insert machined from solid brass and crimped in place, and a nozzle insulator constructed from G7 silicone material. The silicone insulator provides the electrical isolation required between the nozzle and gas diffuser without the need for a separate insulator component. The bore measures 5\/8 inch with a 3.25 inch length and 0.875 inch OD. This nozzle is installed by professional welders and MIG welding technicians in fabrication, structural, and industrial settings.\u003c\/p\u003e\n\u003cp\u003eThe 1260-1608 is suited for medium to heavy duty MIG welding operations requiring reliable gas coverage and electrical insulation at elevated amperages up to 450A. Its recessed contact tip relationship of 0.125 to 0.156 inches makes it appropriate for higher heat applications where longer electrical stick-out is needed, as well as tack, spot, and stitch welding where the nozzle may contact the workpiece. The slip-on design fits over the metal spring of a standard gas diffuser, making installation and replacement straightforward on compatible MIG torch setups. Sold as a 2-piece pack.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-piece design eliminates the need for an additional external insulator\u003c\/li\u003e\n  \u003cli\u003eNozzle housing formed from 122 DHP copper alloy tubing for durability at high amperages\u003c\/li\u003e\n  \u003cli\u003eNozzle insert machined from solid brass and crimped in place for secure fit over gas diffuser spring\u003c\/li\u003e\n  \u003cli\u003eG7 silicone nozzle insulator provides electrical isolation from the gas diffuser\u003c\/li\u003e\n  \u003cli\u003eRecessed tip relationship of 0.125 to 0.156 inches suited for high-heat, tack, spot, and stitch applications\u003c\/li\u003e\n  \u003cli\u003ePart number rolled and stamped on external surface for easy field identification\u003c\/li\u003e\n  \u003cli\u003eRated up to 450 amps for medium and heavy duty welding use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style slip-on replacement nozzle compatible with standard gas diffuser configurations in medium to heavy duty MIG welding torches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified welding technicians or MIG torch service personnel. Ensure the welding machine is powered down and the torch is fully de-energized before replacing nozzle components. The slip-on design requires sliding the nozzle over the metal spring on the gas diffuser — no threading is needed. Inspect the gas diffuser and contact tip for wear before reinstalling to avoid premature nozzle failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 0.625 inches\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\u003eRecessed Tip Relationship\u003c\/strong\u003e: 0.125 to 0.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 450 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Housing Material\u003c\/strong\u003e: 122 DHP copper alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Insert Material\u003c\/strong\u003e: Solid brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Insulator Material\u003c\/strong\u003e: G7 silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Slip-on\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: 0.22 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: 1260-1608\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346594496818,"sku":"1260-1608","price":66.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546023.jpg?v=1782084782","url":"https:\/\/voomisupply.com\/products\/tweco-1260-1608-mig-nozzle-5-8-inch-bore-3-25-inch-450a","provider":"Voomi Supply","version":"1.0","type":"link"}
