It features a 1\/2 inch bore and measures 3.03 inches in length with a 3\/4 inch outer diameter. The nozzle is machined from 122 DHP copper alloy tubing, a material well suited for higher heat applications that require longer electrical stick-out or situations where the nozzle may contact the work piece. The part number is roll-stamped on the outer surface for fast identification during production or maintenance. Sold in a pack of 2.\u003c\/p\u003e\u003cp\u003eThis nozzle is intended for light to medium duty MIG welding applications drawing up to 250 amps. It slides over a standard nozzle insulator and is adjustable, allowing the operator to dial in the preferred contact tip-to-nozzle relationship. The recessed contact tip relationship of 0.125 to 0.156 inches makes this nozzle a practical choice for tack, spot, and stitch welding passes, as well as any weld sequence where the nozzle may brush the base metal. It fits standard gas diffusers compatible with the Tweco No. 2 gun platform.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2 inch bore with 3\/4 inch OD and 3.03 inch overall length\u003c\/li\u003e\n\u003cli\u003e122 DHP copper alloy construction for high thermal conductivity and heat resistance\u003c\/li\u003e\n\u003cli\u003eAdjustable fit allows operator to set desired contact tip and nozzle relationship\u003c\/li\u003e\n\u003cli\u003eRecessed tip profile (0.125 to 0.156 inches) suited for higher heat and nozzle-to-work contact scenarios\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on outer surface for easy field identification\u003c\/li\u003e\n\u003cli\u003eSlides over standard nozzle insulator without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Tweco No. 2 MIG guns rated up to 250 amps using a standard gas diffuser and standard nozzle insulator.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by welding technicians or experienced MIG operators. Power down and de-energize the MIG gun and wire feeder before replacing nozzle components. Slide the nozzle over the insulator and adjust position to achieve the desired tip recess before securing. Inspect the contact tip and diffuser condition whenever a nozzle is replaced to avoid premature wear on new components.\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: 3.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3\/4 inch\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\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\u003ePackage Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.14 pounds\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: 1220-1111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51347816120626,"sku":"1220-1111","price":28.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545892.jpg?v=1782114369","url":"https:\/\/voomisupply.com\/products\/tweco-1220-1111-mig-nozzle-1-2-inch-bore-250-amp","provider":"Voomi Supply","version":"1.0","type":"link"}
