Built from 122 DHP copper alloy tubing that is cut and formed into the nozzle housing, this nozzle offers reliable heat resistance and conductivity for light to medium duty welding applications. The bore measures 5\/8 inch (0.625 inches) with a 3\/4-inch outer diameter and an overall length of 2.1 inches. An adjustable recess-to-protruding contact tip relationship allows the technician to dial in the exact contact tip and nozzle configuration required for the weld joint at hand. The part number is rolled and stamped on the outer surface for fast field identification.\u003c\/p\u003e\u003cp\u003eThis nozzle is suited for light to medium duty MIG welding applications drawing up to 250 amps. Its adjustable tip geometry covers three common configurations: recessed for higher heat applications with longer electrical stick-out or when the nozzle may contact the work piece during tack, spot, or stitch welding; flush for shorter electrical stick-out and tighter arc lengths; and protruding for open root pipe or tight weld joints requiring deeper nozzle access. The nozzle slides over the standard nozzle insulator on compatible Tweco No. 2 gas diffuser setups. Sold in a pack of 2.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e122 DHP copper alloy construction for high heat conductivity and durability\u003c\/li\u003e\n\u003cli\u003eAdjustable tip position: recessed, flush, or protruding contact tip relationship\u003c\/li\u003e\n\u003cli\u003e5\/8 inch (0.625 inches) bore with 3\/4-inch outer diameter\u003c\/li\u003e\n\u003cli\u003ePart number rolled and stamped on the outer surface for easy identification\u003c\/li\u003e\n\u003cli\u003eSlides over standard nozzle insulator without modification\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. 2 MIG guns and standard gas diffusers rated up to 250 amps.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified welding technicians or MIG gun service personnel. Disconnect and de-energize the welding system before removing or installing front-end consumables. Slide the nozzle over the nozzle insulator and adjust the position to achieve the desired contact tip relationship before tightening. Inspect the nozzle housing for spatter buildup or deformation regularly and replace as needed to maintain shielding gas coverage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.625 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\u003eNozzle Length\u003c\/strong\u003e: 2.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 250 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\u003eTip Adjustment\u003c\/strong\u003e: Recessed to Protruding\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\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: 1220-1120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344939188530,"sku":"1220-1120","price":30.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545890.jpg?v=1782046185","url":"https:\/\/voomisupply.com\/products\/tweco-1220-1120-mig-nozzle-5-8-inch-bore-250-amp","provider":"Voomi Supply","version":"1.0","type":"link"}
