It features a 5\/8-inch bore (ID) and an outer diameter of 1.117 inches, with an overall length of 3.29 inches. The nozzle uses a three-piece construction: a nozzle housing cut-formed from red brass alloy 230, a solid brass machined insert crimped in place to slide over the gas diffuser spring, and a G7 silicone insulator that provides electrical isolation from the gas diffuser. Licensed welding technicians and MIG equipment service professionals install this nozzle as a consumable replacement on HD26 Series torch assemblies.\u003c\/p\u003e\u003cp\u003eThis nozzle is designed for heavy-duty MIG welding environments where sustained high amperage output is required. Rated for use in applications up to 600 amperes, it is suited for industrial and fabrication settings where torch consumables experience rapid thermal cycling and mechanical wear. The air-cooled design makes it appropriate for torch configurations that rely on shielding gas flow for nozzle cooling rather than a water-cooled torch body. The part number is roll-stamped on the exterior surface for quick identification during consumable changeover on the job.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThree-piece nozzle design: housing, insert, and insulator function as a self-contained assembly without requiring a separate additional insulator\u003c\/li\u003e\n\u003cli\u003eNozzle housing cut-formed from red brass alloy 230 for thermal durability\u003c\/li\u003e\n\u003cli\u003eSolid brass nozzle insert machined and crimped in place for secure fitment over the gas diffuser spring\u003c\/li\u003e\n\u003cli\u003eG7 silicone nozzle insulator provides reliable electrical isolation from the gas diffuser\u003c\/li\u003e\n\u003cli\u003eRated for heavy-duty welding applications up to 600 amperes\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on exterior surface for fast identification during consumable changes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement consumable for TWECO HD26 Series MIG welding torches used in heavy-duty applications up to 600 amperes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified welding equipment technicians or MIG torch service personnel. Power down and de-energize the welding system before replacing torch consumables. The slip-on design allows the nozzle to slide over the gas diffuser spring — ensure the diffuser is clean and undamaged before seating the replacement nozzle. Inspect the G7 silicone insulator for cracking or heat damage at each consumable change interval.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter (ID)\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter (OD)\u003c\/strong\u003e: 1.117 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.29 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: Up to 600 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Slip-On, Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling Method\u003c\/strong\u003e: Air-Cooled\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\u003eWeight\u003c\/strong\u003e: 0.41 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HD26\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: 1260-1285\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344050159922,"sku":"1260-1285","price":124.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546017.jpg?v=1782027825","url":"https:\/\/voomisupply.com\/products\/tweco-1260-1285-mig-welding-nozzle-5-8-inch-bore-hd26","provider":"Voomi Supply","version":"1.0","type":"link"}
