The nozzle features a 3\/8-inch (0.375-inch) bore, a 3.25-inch length, and a 0.875-inch outer diameter. It handles currents up to 450 amps, making it suitable for medium to heavy duty welding work. Construction follows a 3-piece design: 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 a separate insulator component. Sold in a pack of 2.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is intended for medium to heavy duty MIG welding environments where current levels can reach 450 amps. It fits standard EL-series gas diffusers and is well-suited for fabrication shops, structural welding, and pipe welding operations. The recessed contact tip relationship of 0.125 to 0.156 inches makes it appropriate for higher-heat applications requiring longer electrical stick-out, as well as tack, spot, and stitch welding where the nozzle may contact the workpiece. Licensed welding technicians and skilled trade welders are the primary installers and users of this consumable.\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 component\u003c\/li\u003e\n  \u003cli\u003eNozzle housing formed from 122 DHP copper alloy tubing for conductivity and durability\u003c\/li\u003e\n  \u003cli\u003eNozzle insert machined from solid brass, crimped in place to slide 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\u003eRecessed contact tip relationship of 0.125 to 0.156 inches suits high-heat and contact welding scenarios\u003c\/li\u003e\n  \u003cli\u003ePart number rolled-stamped on the external surface for quick field identification\u003c\/li\u003e\n  \u003cli\u003eRated up to 450 amps for medium to heavy duty welding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit standard EL-series gas diffusers, including the standard EL gas diffuser thread configuration.

Disconnect and de-energize the welding power source before replacing any front-end consumables. Slide the nozzle over the metal spring on the gas diffuser until fully seated — do not force or over-tighten. Inspect the silicone insulator for wear or cracking at 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: 0.375 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\u003eContact Tip Recess\u003c\/strong\u003e: 0.125 to 0.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Current Rating\u003c\/strong\u003e: 450 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Housing Material\u003c\/strong\u003e: 122 DHP copper alloy tubing\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\u003ePackage Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.21 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: 1260-1606\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344912875826,"sku":"1260-1606","price":66.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546021.jpg?v=1782045333","url":"https:\/\/voomisupply.com\/products\/tweco-1260-1606-slip-on-copper-nozzle-3-8-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
