Built from 122 DHP copper alloy tubing, the nozzle housing is cut and formed for consistent performance under sustained heat. The bore measures 3\/4 inches with an outer diameter of 0.97 inches and an overall length of 3.48 inches. The nozzle-to-contact-tip recess relationship is 0.125 to 0.156 inches. Sold as a 2-pack, this nozzle is designed for standard gas diffusers and slides over the standard nozzle insulator. The part number is roll-stamped on the outer surface for quick field identification.\u003c\/p\u003e\u003cp\u003eThis nozzle is suited for medium to heavy duty MIG welding operations. The adjustable fit allows the technician to set the desired contact tip and nozzle relationship based on application requirements. Recessed tip setups are well-suited for higher heat applications requiring longer electrical stick-out or situations where nozzle contact with the workpiece is likely, such as tack, spot, and stitch welding. Flush tip configurations work where shorter stick-out and tighter arc lengths are needed. Protruding tip setups are common when welding open root pipe or accessing tight joint geometries.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated for welding applications up to 450 amps\u003c\/li\u003e\n\u003cli\u003e3\/4 inch bore with 0.97 inch outer diameter and 3.48 inch overall length\u003c\/li\u003e\n\u003cli\u003eHousing cut and formed from 122 DHP copper alloy tubing\u003c\/li\u003e\n\u003cli\u003eAdjustable nozzle position to dial in contact tip and nozzle relationship\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on outer surface for fast identification in the field\u003c\/li\u003e\n\u003cli\u003eSold as a 2-pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard gas diffusers and slides over the standard nozzle insulator, compatible with TWECO part 34A (stock number 1340-1100).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and replacement should be performed by a qualified welding technician with the MIG welder powered down and the wire feed disabled before handling front-end consumables. Ensure the nozzle is fully seated over the nozzle insulator before resuming operation. Inspect the nozzle regularly for spatter buildup, which can restrict shielding gas flow and reduce weld quality. Follow the equipment manufacturer guidelines for front-end assembly torque and seating procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.97 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 450 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Recess\u003c\/strong\u003e: 0.125 to 0.156 inches\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 Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246057361\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: 1240-1231\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51347374899506,"sku":"1240-1231","price":29.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545930.jpg?v=1782103020","url":"https:\/\/voomisupply.com\/products\/tweco-1240-1231-mig-welding-nozzle-3-4-in-bore-450a","provider":"Voomi Supply","version":"1.0","type":"link"}
