It features a nozzle housing cut and formed from 122 DHP copper alloy tubing, a nozzle insert machined from solid brass with internal threads matched to the conductor tube, and a G7 silicone nozzle insulator that provides electrical insulation between the nozzle and the gas diffuser. The 3-piece tapered design does not require a separate insulator. Bore diameter is 3\/4 inches. The part number is roll-stamped on the outside surface for quick identification in the field. Welders and weld shop technicians handling heavy-duty GMAW applications will find this nozzle a direct-fit replacement for 25 Series torches.\u003c\/p\u003e\u003cp\u003eThe TWECO 1250-1130 is designed for heavy-duty MIG welding environments handling continuous or high-cycle duty up to 500 amperes. It is suited to structural, fabrication, and industrial welding operations where heat and spatter resistance are critical. The nozzle is sold individually and is appropriate for use in both shop and field welding setups where the Weldskill 25 Series gun is the standard torch platform.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNozzle housing formed from 122 DHP copper alloy tubing for high thermal and electrical conductivity\u003c\/li\u003e\n\u003cli\u003eSolid brass nozzle insert with machined 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 eliminates need for an additional insulator\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on exterior surface for quick identification\u003c\/li\u003e\n\u003cli\u003eRated for heavy-duty welding up to 500 amperes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement nozzle for TWECO Weldskill 25 Series MIG welding guns.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified welders or weld equipment technicians. Disconnect and de-energize the welding power source before removing or installing any nozzle components. Allow the existing nozzle to cool completely before handling to avoid burns. Ensure the internal threads of the replacement insert are fully engaged with the conductor tube before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 3\/4 inches\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\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\u003eLength\u003c\/strong\u003e: 3.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\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: 1250-1130\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51345245405490,"sku":"1250-1130","price":66.36,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546010.jpg?v=1782052774","url":"https:\/\/voomisupply.com\/products\/tweco-1250-1130-mig-welding-nozzle-3-4-inch-bore-25-series","provider":"Voomi Supply","version":"1.0","type":"link"}
