It features a 5\/8-inch (0.625-inch) bore and an overall length of 3.25 inches with a 0.875-inch outside diameter. Rated for medium to heavy-duty welding applications up to 450 amps, this nozzle is built from a 3-piece construction: a housing cut and formed from 122 DHP copper alloy tubing, an insert machined from solid brass, and an insulator constructed from G7 silicone material. The part number is roll-stamped on the exterior surface for fast identification in the field. Sold as a pack of 2.\u003c\/p\u003e\n\u003cp\u003eThis nozzle threads directly onto a standard EL gas diffuser and is suited for medium to heavy-duty MIG welding environments including fabrication shops, structural steel work, and pipe welding. The recessed contact tip relationship of 0.125 to 0.156 inches makes it well-suited for higher heat applications where longer electrical stick-out is required, as well as tack, spot, and stitch welding scenarios where the nozzle may contact the work piece. Licensed welders and professional fabricators working with wire-feed MIG equipment will find this a direct-fit consumable replacement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-piece design eliminates need for an additional insulator — nozzle housing, insert, and insulator integrated\u003c\/li\u003e\n  \u003cli\u003eHousing cut and formed from 122 DHP copper alloy tubing for durability and conductivity\u003c\/li\u003e\n  \u003cli\u003eBrass insert machined with internal threads to match EL gas diffuser thread pattern\u003c\/li\u003e\n  \u003cli\u003eG7 silicone nozzle insulator provides electrical insulation from the gas diffuser\u003c\/li\u003e\n  \u003cli\u003eRecessed tip geometry supports higher heat and longer stick-out welding applications up to 450A\u003c\/li\u003e\n  \u003cli\u003ePart number roll-stamped on exterior surface for quick identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to thread onto standard EL gas diffusers.

Always power down and disconnect the welding machine before replacing nozzle consumables. Hand-thread the nozzle onto the EL gas diffuser until snug — do not use tools that could damage the threads or insulator. Inspect the G7 silicone insulator for cracking or spatter buildup during each nozzle 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 Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.875 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\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\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\u003eThread Type\u003c\/strong\u003e: Coarse thread, EL gas diffuser compatible\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: 1260-1652\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51347307266354,"sku":"1260-1652","price":74.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546042.jpg?v=1782101029","url":"https:\/\/voomisupply.com\/products\/tweco-1260-1652-copper-welding-nozzle-5-8-inch-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
