Built as a 3-piece assembly, it combines 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 components. This design handles current loads up to 500 amperes. The part number is roll-stamped on the outside surface for fast identification in the field. Welding technicians and fabricators working with high-amperage MIG setups will find this nozzle a direct-fit service replacement.\u003c\/p\u003e\u003cp\u003eThis nozzle is intended for heavy-duty MIG welding applications requiring reliable shielding gas delivery at high amperages. The tapered 3-piece nozzle design eliminates the need for a separate additional insulator, simplifying installation and reducing component count during maintenance. It is suited for industrial fabrication, structural welding, and production environments where continuous high-amperage output is standard. The 1\/2-inch bore accommodates common wire diameters used in demanding weld applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-piece design: 122 DHP copper alloy housing, solid brass insert, and G7 silicone insulator\u003c\/li\u003e\n\u003cli\u003eRated for welding applications up to 500 amperes\u003c\/li\u003e\n\u003cli\u003eInternal threads on brass insert are machined to match the conductor tube for precise fit\u003c\/li\u003e\n\u003cli\u003eTapered design does not require an additional external insulator\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on exterior for quick field identification\u003c\/li\u003e\n\u003cli\u003eStandard 1\/2-inch bore for common MIG wire diameter compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement nozzle for TWECO 25 Series MIG welding guns and conductor tubes operating at up to 500 amperes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified welding equipment technicians or experienced MIG operators. Disconnect and de-energize the welding power source completely before removing or installing the nozzle. Inspect the conductor tube threads for wear or damage before threading on the new nozzle insert to ensure a secure, gas-tight fit. Do not over-tighten the nozzle assembly, as damage to the brass insert threads may result.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 500 amps\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: 2.4 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: 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\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: 1250-1410\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51345725522226,"sku":"1250-1410","price":36.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546009.jpg?v=1782061766","url":"https:\/\/voomisupply.com\/products\/tweco-1250-1410-mig-welding-nozzle-standard-1-2-inch-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
