It is engineered for use with robotic and fixed-automation MIG guns where consistent gas coverage and repeatable front-end geometry are critical. The nozzle housing is machined from tellurium copper alloy bar for effective heat dissipation. The insert is machined from solid brass with internal threads matched to the gas diffuser. A G7 silicone insulator provides electrical isolation from the gas diffuser without requiring an additional insulator. The 3\/4-inch bore and bottle-shaped geometry make it well suited for robotic weld cells equipped with nozzle cleaning stations.\u003c\/p\u003e\u003cp\u003eThis nozzle is designed for light to medium duty welding applications up to 600 A where longer electrical stick-out is required. The 5\/32-inch tip recess positions the contact tip back from the nozzle face, making it appropriate for higher-heat applications and situations where the nozzle may contact the workpiece during tack, spot, or stitch welding sequences. The straight bore at the front end of the nozzle allows thorough cleaning of the side walls during automated cleaning cycles, helping maintain consistent shielding gas flow throughout production runs. The part number is roll-stamped on the outside surface for easy identification during changeovers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-piece design: tellurium copper alloy housing, solid brass insert, G7 silicone insulator — no additional insulator required\u003c\/li\u003e\n\u003cli\u003eRated up to 600 amps for light to medium duty robotic MIG welding\u003c\/li\u003e\n\u003cli\u003e3\/4-inch bore diameter with straight ID for effective nozzle cleaning station compatibility\u003c\/li\u003e\n\u003cli\u003e5\/32-inch tip recess suited for higher-heat applications and workpiece-contact weld sequences\u003c\/li\u003e\n\u003cli\u003eBottle-shaped geometry designed for robotic and fixed-automation MIG gun front ends\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on exterior for fast visual identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to work with robotic and fixed-automation MIG guns requiring a REL24-pattern nozzle assembly with a matching gas diffuser thread configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified welding technicians or robotic weld cell maintenance personnel. De-energize the welding power source and allow the gun front end to cool before replacing nozzle components. Thread the brass insert to the gas diffuser by hand first to confirm engagement before applying a tool, and avoid over-tightening, which can damage the insert threads. Verify shielding gas flow rate after reassembly before returning the cell to production.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 600 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Recess\u003c\/strong\u003e: 5\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Design\u003c\/strong\u003e: Straight, bottle-shaped geometry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Tellurium 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\u003eLength\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\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: 1240-1312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346237129010,"sku":"1240-1312","price":64.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545981.jpg?v=1782074865","url":"https:\/\/voomisupply.com\/products\/tweco-1240-1312-robotic-mig-nozzle-600a-3-4-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
