It features a 3\/4 inch bore and a tapered nozzle design that provides shielding gas coverage during continuous or heavy-duty MIG welding operations. The nozzle housing is cut and formed from 122 DHP copper alloy tubing for heat resistance and conductivity. The internal insert is machined from solid brass with threaded fitment to match the conductor tube. A G7 silicone nozzle insulator provides electrical isolation without requiring a separate add-on insulator. Licensed welding technicians and fabricators install this nozzle as a consumable replacement on MIG welding guns rated up to 500 amperes.\u003c\/p\u003e\u003cp\u003eThis nozzle is suited for heavy-duty welding applications where sustained arc performance and reliable gas coverage are required. The 1\/8 inch tip recess geometry positions the contact tip slightly behind the nozzle face, which helps protect the tip from spatter and is a common setup for short-circuit and spray transfer processes. The part number is roll-stamped on the outer surface for easy identification in multi-gun shops or high-volume consumable environments. It is sold individually and is a direct replacement consumable for Tweco 25 Series MIG gun assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNozzle housing formed from 122 DHP copper alloy tubing for thermal conductivity and durability\u003c\/li\u003e\n\u003cli\u003eBrass insert machined from solid stock with internal threads matched to the conductor tube\u003c\/li\u003e\n\u003cli\u003eG7 silicone nozzle insulator provides electrical insulation without a separate insulator component\u003c\/li\u003e\n\u003cli\u003eTapered 3-piece design rated for welding applications up to 500 amperes\u003c\/li\u003e\n\u003cli\u003e1\/8 inch tip recess for contact tip protection in spatter-heavy environments\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on outer surface for fast field identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct replacement consumable nozzle for Tweco 25 Series and 25CT MIG welding gun assemblies rated up to 500 amperes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by welding technicians as part of routine MIG gun consumable maintenance. Power down and de-energize the welding power source before removing or installing nozzle components. Thread the nozzle assembly onto the conductor tube by hand until snug; do not use tools that could damage the brass insert threads or the copper housing. 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\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Length\u003c\/strong\u003e: 2.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Recess\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage Rating\u003c\/strong\u003e: 500 amperes\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\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: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.4 x 1.1 x 1.1 inches\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: 1250-1430\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344951247154,"sku":"1250-1430","price":59.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546012.jpg?v=1782046605","url":"https:\/\/voomisupply.com\/products\/tweco-1250-1430-mig-welding-nozzle-3-4-in-bore-25-series","provider":"Voomi Supply","version":"1.0","type":"link"}
