It features a 5\/8-inch (0.625-inch) bore, an outer diameter of 1.117 inches, and a length of 3.29 inches. The nozzle uses a recessed contact tip relationship of 0.125 to 0.156 inches, making it well suited for applications requiring longer electrical stick-out or situations where the nozzle may contact the workpiece. The part number is rolled and stamped on the outer surface for fast field identification. Sold in a pack of 2, this nozzle is intended for professional welders working in high-amperage, heavy-duty environments.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is designed for heavy-duty MIG welding applications drawing up to 450 amps. The recessed tip configuration is appropriate for higher heat applications, tack welding, spot welding, and stitch welding where longer electrical stick-out is needed or where nozzle-to-workpiece contact is likely. It fits standard gas diffusers compatible with the Tweco SprayMaster MIG gun platform and is a direct fit for HD24-series front-end consumable setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-piece design: nozzle housing, nozzle insert, and nozzle insulator — no additional insulator required\u003c\/li\u003e\n  \u003cli\u003eNozzle housing cut and formed from 122 DHP copper alloy tubing for high conductivity and heat resistance\u003c\/li\u003e\n  \u003cli\u003eNozzle insert machined from solid brass and crimped in place to slide over the gas diffuser metal spring\u003c\/li\u003e\n  \u003cli\u003eNozzle insulator constructed from G7 silicone material, providing electrical insulation from the gas diffuser\u003c\/li\u003e\n  \u003cli\u003eRecessed contact tip relationship of 0.125 to 0.156 inches for longer stick-out and workpiece contact tolerance\u003c\/li\u003e\n  \u003cli\u003ePart number rolled and stamped on outer surface for easy identification during service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 450-amp Tweco SprayMaster MIG guns and fits standard gas diffusers within that gun platform.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified welding technicians or MIG gun service personnel. Power down and disconnect the welding machine before replacing front-end consumables. Ensure the gas diffuser spring is clean and undamaged before sliding the nozzle insert into place. Do not overtighten or force the slip-on fit, as this can damage the nozzle insulator or the diffuser spring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Length\u003c\/strong\u003e: 3.29 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1.117 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 450 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Tip Recess\u003c\/strong\u003e: 0.125 to 0.156 inches\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\u003eNozzle Insulator Material\u003c\/strong\u003e: G7 silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1240-1241\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346832687410,"sku":"1240-1241","price":61.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545973.jpg?v=1782091755","url":"https:\/\/voomisupply.com\/products\/tweco-1240-1241-slip-on-mig-nozzle-5-8-inch-bore-450a","provider":"Voomi Supply","version":"1.0","type":"link"}
