The nozzle features a 3\/4 inch bore and a 3-piece construction consisting of a nozzle housing cut and formed from 122 DHP copper alloy tubing, a brass nozzle insert with machined internal threads, and a G7 silicone nozzle insulator. The part number is rolled and stamped on the external surface for quick field identification. Sold in a pack of 2, this nozzle is a direct-threading replacement for standard EL series gas diffusers used by professional welders and MIG technicians.\u003c\/p\u003e\u003cp\u003eThe 1260-1658 is suited for medium to heavy duty MIG welding operations up to 200 amps. The recessed contact tip relationship, measuring 0.125 to 0.156 inches, makes it appropriate for higher heat applications requiring longer electrical stick-out, as well as tack, spot, and stitch welding where the nozzle may contact the work piece. Its copper alloy construction supports efficient heat dissipation during sustained welding cycles, and the silicone insulator provides reliable electrical isolation from the gas diffuser throughout operation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-piece design: nozzle housing, brass insert, and silicone insulator — no additional insulator required\u003c\/li\u003e\n\u003cli\u003eNozzle housing formed from 122 DHP copper alloy tubing for consistent dimensional stability and heat dissipation\u003c\/li\u003e\n\u003cli\u003eNozzle insert machined from solid brass with internal threads matched to standard EL gas diffuser\u003c\/li\u003e\n\u003cli\u003eG7 silicone nozzle insulator provides electrical insulation from the gas diffuser\u003c\/li\u003e\n\u003cli\u003eRecessed contact tip relationship of 0.125 to 0.156 inches for higher heat and tack, spot, or stitch applications\u003c\/li\u003e\n\u003cli\u003ePart number rolled and stamped on the external surface for easy identification in the field\u003c\/li\u003e\n\u003cli\u003eSold as a pack of 2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to thread onto standard Tweco Eliminator EL series gas diffusers for MIG welding guns rated up to 200 amps.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified welding technician with the welding machine powered down and the gun cool before handling front-end consumables. Thread the nozzle onto the EL gas diffuser by hand until seated — do not overtighten, as this can damage the nozzle insert threads or insulator. Inspect the insulator and housing for wear or spatter buildup at each consumable change interval.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 200 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\u003eNozzle Housing Material\u003c\/strong\u003e: 122 DHP copper alloy tubing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Insert Material\u003c\/strong\u003e: Solid brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Insulator Material\u003c\/strong\u003e: G7 silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: 3-piece\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 pounds\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: 608246139975\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: 1260-1658\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51347478479154,"sku":"1260-1658","price":41.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546043.jpg?v=1782106237","url":"https:\/\/voomisupply.com\/products\/tweco-1260-1658-welding-nozzle-3-4-in-bore-200a","provider":"Voomi Supply","version":"1.0","type":"link"}
