It features a 5\/8 inch (0.625 inch) bore and an overall length of 3.018 inches with a 0.875 inch outer diameter. The nozzle uses a flush contact tip relationship with a 0.062 inch offset. Its three-piece construction eliminates the need for a separate insulator and uses 122 DHP copper alloy tubing for the housing, solid brass for the machined insert, and a G7 silicone insulator for electrical isolation from the gas diffuser. Sold in a pack of 2.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is suited for light to medium duty MIG welding environments where amperage does not exceed 250A. The flush tip configuration is appropriate for applications requiring shorter electrical stick-out and tighter arc lengths, bringing the contact tip closer to the work piece. It threads directly onto a standard EL gas diffuser, making it a straightforward drop-in replacement in common MIG torch setups used by welding professionals in fabrication, maintenance, and repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-piece design — nozzle housing, insert, and insulator — requires no additional insulator\u003c\/li\u003e\n  \u003cli\u003eHousing cut and formed from 122 DHP copper alloy tubing for conductivity and durability\u003c\/li\u003e\n  \u003cli\u003eNozzle insert machined from solid brass with internal threads matched to the EL gas diffuser\u003c\/li\u003e\n  \u003cli\u003eG7 silicone nozzle insulator provides electrical isolation from the gas diffuser\u003c\/li\u003e\n  \u003cli\u003eFlush contact tip relationship at 0.062 inch offset for shorter stick-out applications\u003c\/li\u003e\n  \u003cli\u003ePart number rolled and stamped on the external surface for easy field identification\u003c\/li\u003e\n  \u003cli\u003eSold as a pack of 2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to thread onto a standard EL gas diffuser.

Power down and de-energize the welding system before replacing nozzle components. Thread the nozzle onto the EL gas diffuser by hand until snug — do not overtighten, as the brass insert and silicone insulator can be damaged by excessive force. Inspect the nozzle insulator and insert for spatter buildup or wear at each consumable change interval.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.625 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\u003eNozzle Length\u003c\/strong\u003e: 3.018 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Tip Relationship\u003c\/strong\u003e: Flush, 0.062 inch offset\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 250 amps\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, no additional insulator required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\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: 1260-1637\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346532434226,"sku":"1260-1637","price":80.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546040.jpg?v=1782082956","url":"https:\/\/voomisupply.com\/products\/tweco-1260-1637-welding-nozzle-5-8-inch-bore-250a","provider":"Voomi Supply","version":"1.0","type":"link"}
