The nozzle features a 0.625-inch bore, a 0.875-inch OD, and a 3.1-inch length. It is constructed with a 3-piece design: a nozzle housing cut and formed from 122 DHP copper alloy tubing, a nozzle insert machined from solid brass, and a nozzle insulator made from G7 silicone material. The brass insert is crimped in place so the nozzle slides over the metal spring of the gas diffuser. The part number is rolled-stamped on the outer surface for quick field identification. Sold in packs of 2.\u003c\/p\u003e\u003cp\u003eThis nozzle fits standard gas diffusers and is rated for welding applications up to 450 A. The recessed tip geometry provides a flush contact tip relationship of 0.062 inches, making it suited for higher-heat applications where longer electrical stick-out is required and for situations where the nozzle may contact the workpiece, such as tack, spot, and stitch welding. The G7 silicone insulator provides the electrical isolation required between the nozzle and gas diffuser without the need for a separate insulator component.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e450 A rating for medium to heavy-duty MIG welding applications\u003c\/li\u003e\n\u003cli\u003e5\/8-inch (0.625-inch) bore fits standard gas diffusers on Tweco SprayMaster MIG guns\u003c\/li\u003e\n\u003cli\u003e3-piece design: 122 DHP copper alloy housing, solid brass machined insert, G7 silicone insulator\u003c\/li\u003e\n\u003cli\u003eNozzle insulator eliminates the need for an additional separate insulator\u003c\/li\u003e\n\u003cli\u003eFlush contact tip relationship of 0.062 inches suited for tack, spot, and stitch welding\u003c\/li\u003e\n\u003cli\u003ePart number rolled-stamped on outer surface for easy field identification\u003c\/li\u003e\n\u003cli\u003eSold as 2 per pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 450 A Tweco SprayMaster MIG guns equipped with a standard gas diffuser.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified welding technicians or MIG gun service personnel. Ensure the welder is fully powered down and the gun is cool before replacing front-end consumables. The nozzle slides over the metal spring of the gas diffuser — verify the brass insert seats fully before resuming operation. Inspect the silicone insulator for damage during each consumable change to maintain proper electrical isolation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle OD\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Length\u003c\/strong\u003e: 3.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 450 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Relationship\u003c\/strong\u003e: Flush, 0.062 inches recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing 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: 0.21 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 per pack\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: 1240-1205\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346370953522,"sku":"1240-1205","price":64.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545936.jpg?v=1782078532","url":"https:\/\/voomisupply.com\/products\/tweco-1240-1205-mig-nozzle-450a-5-8-inch-bore-slip-on","provider":"Voomi Supply","version":"1.0","type":"link"}
