The nozzle features a 3\/8 inch (0.375 inch) bore, measures 3.49 inches in length, and is constructed from 122 DHP copper alloy tubing for reliable performance in high-heat environments. The housing is cut and formed from copper alloy tubing, and the part number is roll-stamped on the outer surface for quick field identification. This nozzle ships in a pack of 2. Licensed welders and MIG welding technicians working in fabrication, manufacturing, or structural welding install this component as a routine front-end consumable replacement.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is suited for medium to heavy duty MIG welding applications requiring up to 450 amps of output. The recessed contact tip relationship of 0.125 to 0.156 inches makes it well suited for higher heat cycles, longer electrical stick-out situations, tack welding, spot welding, stitch welding, and applications where the nozzle may contact the workpiece. It slides over the standard nozzle insulator and can be repositioned to adjust the contact tip-to-nozzle relationship as needed for the weld joint.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConstructed from 122 DHP copper alloy tubing for high-heat durability\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch bore with 3.49 inch length and 3\/4 inch OD\u003c\/li\u003e\n  \u003cli\u003eRecessed contact tip relationship of 0.125 to 0.156 inches — suited for longer stick-out and nozzle-to-work contact scenarios\u003c\/li\u003e\n  \u003cli\u003ePart number roll-stamped on outer surface for fast identification during consumable changes\u003c\/li\u003e\n  \u003cli\u003eSlides over standard nozzle insulator with adjustable tip-to-nozzle positioning\u003c\/li\u003e\n  \u003cli\u003eSold as 2 per pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Tweco No. 4 MIG guns rated up to 450 amps.

Always power down and de-energize the welding system before servicing front-end consumables. Slide the nozzle over the nozzle insulator and adjust the position to achieve the desired contact tip and nozzle relationship before resuming operation. Inspect nozzle condition regularly, as spatter buildup and heat cycling will degrade performance over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Length\u003c\/strong\u003e: 3.49 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecessed Tip Relationship\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\u003ePack Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\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: 1240-1301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51347927302450,"sku":"1240-1301","price":79.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545972.jpg?v=1782116265","url":"https:\/\/voomisupply.com\/products\/tweco-1240-1301-mig-welding-nozzle-3-8-inch-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
