It features a 5\/8-inch (0.625-inch) bore and an overall length of 3.138 inches with a 0.875-inch outside diameter. Rated for welding applications up to 250 amps, it uses a 3-piece construction that eliminates the need for a separate insulator. The nozzle housing is cut and formed from 122 DHP copper alloy tubing, the insert is machined from solid brass and crimped in place, and the insulator is constructed from G7 silicone material. The part number is roll-stamped on the exterior surface for quick field identification. Sold in a pack of 2.\u003c\/p\u003e\u003cp\u003eThis nozzle is suited for light to medium duty MIG welding applications up to 250 amps. The recessed contact tip relationship of 0.125 to 0.156 inches makes it appropriate for higher heat applications, situations requiring longer electrical stick-out, and tack, spot, or stitch welding where the nozzle may contact the workpiece. It threads onto the standard EL-series gas diffuser and slides over the metal spring that is integral to the diffuser assembly. Typical install environments include fabrication shops, structural work, and maintenance welding operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-piece design eliminates the need for an additional insulator\u003c\/li\u003e\n\u003cli\u003eNozzle housing formed from 122 DHP copper alloy tubing for conductivity and durability\u003c\/li\u003e\n\u003cli\u003eBrass insert machined from solid stock and crimped in place for secure retention on 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 higher heat and contact welding scenarios\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on exterior for fast identification during inventory and service\u003c\/li\u003e\n\u003cli\u003eSold as 2 per pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard EL-series gas diffusers.

Disconnect and de-energize the welding machine before servicing front-end consumables. Slide the nozzle over the gas diffuser spring until fully seated and confirm the insulator is properly positioned to maintain electrical isolation. Inspect the nozzle insert seating and insulator condition at 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: 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: 3.138 inches\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\u003eCurrent 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\u003ePackage Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\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: 1260-1603\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51343020163378,"sku":"1260-1603","price":57.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546019.jpg?v=1782014020","url":"https:\/\/voomisupply.com\/products\/tweco-1260-1603-slip-on-copper-mig-nozzle-5-8-inch-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
