Manufactured from 122 DHP copper alloy tubing that is cut and formed to shape, it provides reliable heat resistance suited for light to medium duty welding applications. The nozzle features a 0.5-inch bore and measures 2.1 inches in length with a 0.75-inch outer diameter. An adjustable recess-to-protruding contact tip relationship lets the technician dial in the precise tip-to-nozzle geometry required for the weld joint at hand. The part number is roll-stamped on the outer surface for fast identification in the field.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is intended for light to medium duty MIG welding applications drawing up to 250 amps. The adjustable tip relationship supports three common configurations. Recessed tip setups suit higher heat applications requiring longer electrical stick-out or situations where the nozzle may contact the work piece, such as tack, spot, and stitch welds. Flush tip setups work where a shorter electrical stick-out and tighter arc length are preferred. Protruding tip setups are used when welding open root pipe or tight weld joints where reach into the joint is necessary. This nozzle is compatible with the standard Tweco nozzle insulator and standard gas diffuser for the No. 2 gun series. Sold as 2 per pack.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e122 DHP copper alloy construction for effective heat dissipation in higher heat weld scenarios\u003c\/li\u003e\n  \u003cli\u003eAdjustable recess-to-protruding contact tip relationship for flexible weld joint geometry\u003c\/li\u003e\n  \u003cli\u003eSlides over the standard Tweco nozzle insulator without modification\u003c\/li\u003e\n  \u003cli\u003ePart number roll-stamped on outer surface for quick identification\u003c\/li\u003e\n  \u003cli\u003eNozzle housing cut and formed from copper alloy tubing for consistent bore geometry\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-piece pack to reduce downtime during nozzle changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\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\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified welding technicians or MIG gun service personnel. Always power down and de-energize the welding system before changing front-end consumables. Slide the nozzle over the nozzle insulator and adjust the contact tip position to achieve the desired recess, flush, or protruding relationship before resuming welding operations. Inspect the nozzle seating and insulator condition at each change to prevent arcing damage to front-end components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.5 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\u003ePackage Weight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 2.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246056159\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: 1220-1110\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51345281679666,"sku":"1220-1110","price":28.61,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545891.jpg?v=1782053871","url":"https:\/\/voomisupply.com\/products\/tweco-1220-1110-mig-welding-nozzle-1-2-in-bore-250a","provider":"Voomi Supply","version":"1.0","type":"link"}
