Built for light-to-medium duty welding applications up to 250 amps, this nozzle uses a 3-piece construction that eliminates the need for a separate insulator. The assembly includes a nozzle housing cut and formed from 122 DHP copper alloy tubing, a nozzle insert machined from solid brass, and a nozzle insulator constructed from G7 silicone material. The nozzle insert is crimped in place, allowing the assembly to slide over the metal spring integral to the gas diffuser. The part number is roll-stamped on the exterior surface for quick field identification. Sold in a pack of 2.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is suited for residential and light commercial MIG welding setups where consistent shielding gas flow and electrical insulation from the diffuser are required. The threaded interface mates with standard EL-series gas diffusers. The 3\/4-inch bore size accommodates standard gas coverage for applications up to 250 A. Typical install scenarios include fabrication shops, maintenance welding, and field repair work where reliable front-end consumables reduce downtime. Both flush and recessed tip configurations benefit from this nozzle design depending on stick-out and joint access requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-piece design eliminates the need for a separate insulator, simplifying assembly and replacement\u003c\/li\u003e\n  \u003cli\u003eNozzle housing 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 and crimped in place for secure fit over the gas diffuser spring\u003c\/li\u003e\n  \u003cli\u003eG7 silicone nozzle insulator provides required electrical isolation from the gas diffuser\u003c\/li\u003e\n  \u003cli\u003ePart number roll-stamped on exterior surface for fast identification in the field\u003c\/li\u003e\n  \u003cli\u003eRated for welding applications up to 250 amps\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-piece pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard EL-series gas diffusers.

Always power down the welding system and disconnect from the power source before replacing front-end consumables. Thread the nozzle onto the EL gas diffuser by hand until fully seated, ensuring the nozzle insert slides properly over the diffuser spring. Inspect the silicone insulator for damage during each consumable change to maintain proper electrical isolation.\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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 250 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\u003eInsulator Material\u003c\/strong\u003e: G7 Silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDesign\u003c\/strong\u003e: 3-Piece, No Additional Insulator Required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246148496\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: 1260-1604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344831316274,"sku":"1260-1604","price":32.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546022.jpg?v=1782044446","url":"https:\/\/voomisupply.com\/products\/tweco-1260-1604-mig-welding-nozzle-3-4-inch-copper","provider":"Voomi Supply","version":"1.0","type":"link"}
