Constructed from 122 DHP copper alloy tubing, this nozzle measures 3.48 inches in length with a 1\/2-inch bore and a 0.875-inch outer diameter. The recessed contact tip relationship of 0.125 to 0.156 inches makes it well suited for higher-heat applications requiring longer electrical stick-out. The part number is roll-stamped on the outer surface for fast field identification. Sold as 2 per pack, this nozzle is a direct-fit component for technicians performing medium to heavy duty MIG welding work.\u003c\/p\u003e\u003cp\u003eThis nozzle is intended for medium to heavy duty MIG welding applications drawing up to 450 amps. The recessed tip geometry is appropriate for tack, spot, and stitch welding scenarios where the nozzle may contact the work piece, or where longer electrical stick-out is required to manage heat input. It slides over the standard nozzle insulator, part number 34A (stock number 1340-1100), and is compatible with the standard gas diffuser used on Tweco No. 4 MIG guns. Welding professionals working in fabrication, structural, or heavy manufacturing environments will find this nozzle a reliable consumable for demanding cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e122 DHP copper alloy construction for thermal conductivity and durability in high-amperage applications\u003c\/li\u003e\n\u003cli\u003eRecessed tip design with 0.125 to 0.156 inch tip recess for higher heat and longer stick-out requirements\u003c\/li\u003e\n\u003cli\u003e1\/2-inch bore with 0.875-inch OD for proper gas shielding coverage\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on outer surface for quick identification during consumable changes\u003c\/li\u003e\n\u003cli\u003eFits over standard nozzle insulator part 34A (stock number 1340-1100)\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 Tweco No. 4 MIG guns rated up to 450 amps using a standard gas diffuser and standard nozzle insulator part 34A (stock number 1340-1100).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified welder or welding equipment technician with the power source switched off and the gun cable de-energized before handling front-end consumables. Slide the nozzle over the nozzle insulator until fully seated and confirm the bore is centered over the contact tip before resuming operation. Inspect the nozzle regularly for spatter buildup and replace when bore erosion affects shielding gas coverage. Follow the gun manufacturer's maintenance guidelines and applicable ANSI Z49.1 safety practices for welding equipment service.\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\u003eNozzle Length\u003c\/strong\u003e: 3.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Recess\u003c\/strong\u003e: 0.125 to 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 450 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 122 DHP Copper Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246057224\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: 1240-1111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51342961508658,"sku":"1240-1111","price":17.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545941.jpg?v=1782012016","url":"https:\/\/voomisupply.com\/products\/tweco-1240-1111-mig-nozzle-1-2-inch-bore-recessed-tip","provider":"Voomi Supply","version":"1.0","type":"link"}
