Built from 122 DHP copper alloy tubing, the nozzle housing is cut and formed for consistent conductivity and durability in light to medium duty welding applications. The bore measures 3\/8 inch, and the recessed contact tip relationship is 0.125 to 0.156 inches, making it well suited for higher heat applications requiring 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 in the field. Sold in a pack of 2.\u003c\/p\u003e\n\u003cp\u003eThis nozzle fits into residential, commercial, and light industrial MIG welding setups where a Tweco No. 2 gun is in service. It slides over the standard nozzle insulator and can be adjusted to achieve the preferred contact tip and nozzle relationship. The recessed tip configuration is particularly suited for tack, spot, and stitch welding where the nozzle may touch the work piece or where longer electrical stick-out is needed to manage heat input. Licensed welding professionals and fabricators working in production or maintenance environments will find this nozzle a direct OEM-style replacement for worn front-end consumables.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e122 DHP copper alloy construction for high thermal and electrical conductivity\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch bore size compatible with Tweco No. 2 MIG guns up to 250A\u003c\/li\u003e\n  \u003cli\u003eRecessed contact tip relationship of 0.125 to 0.156 inches for higher heat and longer stick-out applications\u003c\/li\u003e\n  \u003cli\u003eAdjustable fit over standard nozzle insulator for customizable tip-to-nozzle relationship\u003c\/li\u003e\n  \u003cli\u003ePart number roll-stamped on outer surface for easy field identification\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. 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 welders or MIG gun service technicians. Power down and disconnect the welding machine before replacing front-end consumables. Slide the nozzle over the standard nozzle insulator and adjust the position to achieve the desired contact tip and nozzle relationship before resuming operation. Inspect the nozzle and contact tip regularly for spatter buildup, wear, or arcing damage that can affect weld quality and increase downtime.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 250A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Tip Relationship (Recessed)\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\u003eLength\u003c\/strong\u003e: 3.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246056135\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: 1220-1100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51345899585842,"sku":"1220-1100","price":17.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545899.jpg?v=1782065900","url":"https:\/\/voomisupply.com\/products\/tweco-1220-1100-mig-nozzle-standard-3-8-inch-bore-250a","provider":"Voomi Supply","version":"1.0","type":"link"}
