It features a 3-piece construction: a nozzle housing cut-formed from red brass alloy 230, a nozzle insert machined from solid brass and crimped in place to slide over the gas diffuser spring, and a G7 silicone nozzle insulator that provides electrical isolation from the gas diffuser. The outer diameter measures 1.117 inches and the bore inner diameter is 0.75 inches. Rated for welding applications up to 600 amperes, this nozzle ships as an individual unit and is air-cooled in operation. Licensed welders and professional fabricators install and service this component.\u003c\/p\u003e\u003cp\u003eThis nozzle is designed for heavy-duty welding applications requiring sustained high-amperage output. The HD26 series is used in industrial and fabrication environments where continuous duty cycles and thermal demands exceed the capacity of standard MIG nozzles. The 3-piece design eliminates the need for a separate external insulator, reducing component count during torch assembly and maintenance. It is suited for production welding, structural fabrication, and other applications drawing up to 600 amps.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-piece nozzle design: red brass alloy 230 housing, solid brass machined insert, and G7 silicone insulator\u003c\/li\u003e\n\u003cli\u003eNozzle insert is crimped in place to allow smooth sliding over the gas diffuser metal spring\u003c\/li\u003e\n\u003cli\u003eG7 silicone insulator provides electrical isolation without requiring a separate add-on insulator\u003c\/li\u003e\n\u003cli\u003eRated for heavy-duty welding up to 600 amperes\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on outer surface for quick field identification\u003c\/li\u003e\n\u003cli\u003eAir-cooled design; slip-on mounting style\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement nozzle for TWECO HD26 series MIG welding torches rated for heavy-duty applications up to 600 amperes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and replacement of MIG welding nozzles should be performed by a qualified welder or welding equipment technician. Disconnect and de-energize the welding machine and allow the torch to cool completely before handling the nozzle. Slip the nozzle onto the gas diffuser spring with firm, even pressure until fully seated. Inspect the nozzle insulator for cracking or carbon tracking at each service interval and replace if damage is found.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HD26\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Slip-On\u003c\/li\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Heavy Duty\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 600 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling Method\u003c\/strong\u003e: Air-Cooled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1.117 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Inner Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Red Brass Alloy 230\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert 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 Weight\u003c\/strong\u003e: 0.41 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246331546\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: 1260-1286\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51342989066546,"sku":"1260-1286","price":118.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546014.jpg?v=1782012958","url":"https:\/\/voomisupply.com\/products\/tweco-1260-1286-mig-welding-nozzle-3-4-inch-bore-600a","provider":"Voomi Supply","version":"1.0","type":"link"}
