It features a 1\/2 inch bore, an overall length of 2.383 inches, and a 0.875 inch outer diameter. The nozzle uses a 3-piece construction: a housing cut and formed from 122 DHP copper alloy tubing, an insert machined from solid brass, and an insulator made from G7 silicone material. The part number is rolled and stamped on the outer surface for fast identification in the field. This nozzle is installed by welding technicians working in high-amperage MIG applications.\u003c\/p\u003e\u003cp\u003eThis nozzle is suited for heavy-duty MIG welding applications up to 250 amps where longer electrical stick-out is needed or where the nozzle may contact the work surface. The recessed contact tip relationship of 0.125 to 0.156 inches makes it appropriate for tack, spot, and stitch welding. It fits standard gas diffusers. The nozzle insert slides over the metal spring of the gas diffuser, while the G7 silicone insulator provides the electrical isolation required between the nozzle and the diffuser.

Power down and disconnect the MIG gun from the welding machine before replacing the nozzle. Ensure the nozzle insert is fully seated over the gas diffuser spring before resuming operation. Inspect the silicone insulator for wear or damage during each nozzle change to maintain proper electrical isolation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Length\u003c\/strong\u003e: 2.383 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 250 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Tip Relationship (Recess)\u003c\/strong\u003e: 0.125 to 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: 122 DHP copper alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulator Material\u003c\/strong\u003e: G7 silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 2\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: 1220-1306\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346159894834,"sku":"1220-1306","price":57.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545913.jpg?v=1782072563","url":"https:\/\/voomisupply.com\/products\/tweco-1220-1306-mig-nozzle-slip-on-copper-1-2-inch-250a","provider":"Voomi Supply","version":"1.0","type":"link"}
