It features a 5\/8-inch (0.625-inch) bore and measures 3.164 inches in length with a 1.117-inch outer diameter. The nozzle is constructed from 122 DHP copper alloy and uses a three-piece design consisting of a copper alloy tubing housing, a solid brass machined insert, and a G7 silicone insulator. This combination delivers reliable electrical insulation from the gas diffuser without requiring an additional external insulator. Licensed welding technicians and fabrication shops install this nozzle on compatible MIG guns for demanding production and structural welding environments.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is suited for medium to heavy-duty welding applications up to 450 amps. It is designed for use with standard gas diffusers and provides a flush contact tip relationship of 0.062 inches, making it appropriate for applications where a shorter electrical stick-out is used, which brings the tip closer to the work piece. Flush-style nozzles are commonly selected for shorter arc lengths in production welding. The nozzle insert is crimped in place, allowing the nozzle to slide over the metal spring of the gas diffuser. Sold in a pack of two units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated for welding applications up to 450 amps\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch bore (0.625 inches) with 3.164-inch length and 1.117-inch outer diameter\u003c\/li\u003e\n  \u003cli\u003eThree-piece design: copper alloy housing, solid brass machined insert, G7 silicone insulator — no additional insulator required\u003c\/li\u003e\n  \u003cli\u003e122 DHP copper alloy construction for thermal and electrical conductivity\u003c\/li\u003e\n  \u003cli\u003eFlush tip relationship of 0.062 inches for shorter electrical stick-out applications\u003c\/li\u003e\n  \u003cli\u003ePart number rolled and stamped on outer surface for quick 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 standard gas diffusers on heavy-duty MIG welding guns rated for applications up to 450 amps.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified welders or welding equipment technicians. Always disconnect and de-energize the welding power source before servicing front-end consumables. Ensure the nozzle insert is fully seated over the gas diffuser spring before resuming operation. Do not overtighten or force the nozzle, as the brass insert and silicone insulator can be damaged by improper assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Length\u003c\/strong\u003e: 3.164 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1.117 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 450 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Relationship\u003c\/strong\u003e: Flush, 0.062 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\u003eDesign\u003c\/strong\u003e: 3-piece\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246328188\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: 1240-1236\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344600432946,"sku":"1240-1236","price":75.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545975.jpg?v=1782037517","url":"https:\/\/voomisupply.com\/products\/tweco-1240-1236-heavy-duty-mig-welding-nozzle-5-8-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
