Machined from tellurium copper alloy bar stock, the nozzle housing delivers consistent dimensional stability and efficient heat dissipation across demanding weld cycles. The bore measures 0.625 inches with an outer diameter of 1 inch and an overall length of 3.302 inches. A recess contact tip relationship of 0.125 to 0.156 inches suits standard gas diffuser configurations. Licensed welding technicians and fabrication professionals install this nozzle as part of a water-cooled MIG gun assembly.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is suited for medium and heavy duty MIG welding environments where sustained high-amperage output is required. It threads onto the outer jacket assembly of water-cooled conductor tubes, making it appropriate for industrial fabrication shops, shipyards, structural steel operations, and other applications that push welding duty cycles near the 300-amp threshold. The part number is roll-stamped on the external surface for fast identification during toolbox or consumable inventory checks. Each nozzle ships with a silicone spatter shield included in the pack.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTellurium copper alloy construction for consistent dimensional stability and efficient heat dissipation\u003c\/li\u003e\n  \u003cli\u003e0.625-inch bore sized for standard gas diffuser compatibility\u003c\/li\u003e\n  \u003cli\u003eRecess contact tip relationship of 0.125 to 0.156 inches\u003c\/li\u003e\n  \u003cli\u003eCoarse thread design threads onto outer jacket assembly of water-cooled conductor tubes\u003c\/li\u003e\n  \u003cli\u003ePart number roll-stamped on external surface for easy field identification\u003c\/li\u003e\n  \u003cli\u003eSilicone spatter shield included with each nozzle\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement nozzle for water-cooled MIG gun assemblies using a standard coarse-thread outer jacket configuration rated up to 300 amps.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified welding technician or MIG gun service professional. Disconnect and de-energize the welding power source and allow the gun assembly to cool completely before removing or installing nozzle consumables. Thread the nozzle onto the outer jacket of the water-cooled conductor tube by hand until snug, then verify the spatter shield is seated correctly before resuming operation. Do not over-tighten; doing so can distort the thread engagement or damage the conductor tube jacket.\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\u003eNozzle Length\u003c\/strong\u003e: 3.302 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 300 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Contact Tip Relationship\u003c\/strong\u003e: 0.125 to 0.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tellurium copper alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpatter Shield Material\u003c\/strong\u003e: G7 silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Coarse thread\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246150994\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: 1230-1076\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344302080306,"sku":"1230-1076","price":52.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545926.jpg?v=1782032973","url":"https:\/\/voomisupply.com\/products\/tweco-1230-1076-welding-nozzle-5-8-in-bore-300a-mig","provider":"Voomi Supply","version":"1.0","type":"link"}
