Machined from 122 DHP copper alloy tubing, it delivers consistent electrical conductivity and a smooth bore finish critical to stable arc performance. The 0.073 inch nominal bore accommodates 3\/32 inch (0.062 inch) wire and is rated for heavy-duty welding applications up to 500 amps. Inside diameter tolerance is held to plus or minus 0.003 inches, ensuring reliable wire feed and reduced burnback. The tip uses a 5\/16 inch-18 UNC-2A thread that seats securely against a gas diffuser when installed in the MIG gun. Sold as a pack of 25.\u003c\/p\u003e\u003cp\u003eThis contact tip is suited for heavy-duty MIG welding in industrial and fabrication environments where consistent arc starts and long consumable life are priorities. The 1.97 inch length and 0.345 inch OD are matched to the Tweco 15H gun platform. Each tip is stamped with the part number and wire diameter, speeding up identification during changeovers in production or field welding settings. Licensed welders and certified welding operators in manufacturing, structural steel, and maintenance-repair-operations (MRO) shops are the primary installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.073 inch nominal bore with plus or minus 0.003 inch ID tolerance for controlled wire feed\u003c\/li\u003e\n\u003cli\u003eMachined from 122 DHP copper alloy tubing for consistent conductivity and smooth bore surface\u003c\/li\u003e\n\u003cli\u003eRated for heavy-duty welding up to 500 amps\u003c\/li\u003e\n\u003cli\u003e5\/16 inch-18 UNC-2A threaded style ensures positive contact with gas diffuser\u003c\/li\u003e\n\u003cli\u003ePart number and wire diameter stamped on each tip for fast field identification\u003c\/li\u003e\n\u003cli\u003eSold 25 per pack to reduce changeover downtime\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement contact tip for the Tweco 15H MIG gun platform, accommodating 3\/32 inch wire diameter in threaded-style gas diffuser assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified welding technicians or certified welding operators. Always power down the welder and allow the gun to cool before removing or installing contact tips. Thread the tip in by hand until snug, then tighten with an appropriate wrench — do not overtighten, as this can distort the thread and affect gas diffuser seating. Inspect the bore for spatter buildup at each tip change to maintain wire feed consistency.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.062 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore (Nominal ID)\u003c\/strong\u003e: 0.073 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eID Tolerance\u003c\/strong\u003e: plus or minus 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.345 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.97 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16 inch-18 UNC-2A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 500 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 122 DHP Copper Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246373881\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: 1150-1238\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51347322306866,"sku":"1150-1238","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545849.jpg?v=1782101530","url":"https:\/\/voomisupply.com\/products\/tweco-1150-1238-mig-contact-tip-0-062-in-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
