Machined from extruded or gun-drilled 122 DHP copper alloy tubing, it delivers consistent electrical conductivity and a smooth inside diameter surface held to a tolerance of plus or minus 0.003 inches. The nominal bore is 0.12 inches, accommodating 7\/64-inch welding wire, and the overall length is 1.97 inches. The OD measures 0.345 inches with a 5\/16-18 UNC-2A thread. This tip is installed and serviced by professional welders and MIG gun technicians in fabrication, manufacturing, and industrial welding environments.\u003c\/p\u003e\u003cp\u003eThis contact tip is suited for heavy-duty MIG welding setups operating between 200 and 500 amps. It is compatible with Tweco No. 5 MIG guns and specific Tweco MIG gun series requiring the 15H tip profile. The thick-walled copper construction conducts heat away from the arc, extending service intervals in continuous or high-duty-cycle welding operations. The tip ships individually sold as 25 per pack and is marked with the part number and wire diameter for fast identification at the gun.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e122 DHP copper alloy construction for high electrical conductivity and heat dissipation\u003c\/li\u003e\n\u003cli\u003e0.12-inch nominal bore accommodates 7\/64-inch MIG wire with inside diameter tolerance held to plus or minus 0.003 inches\u003c\/li\u003e\n\u003cli\u003eTwist-lock design locks tip in place on the gas diffuser without loose thread engagement\u003c\/li\u003e\n\u003cli\u003eQuarter-turn clockwise rotation exposes a new wear point, effectively doubling tip service life\u003c\/li\u003e\n\u003cli\u003eThick-walled design acts as a heat sink, drawing heat away from the arc source\u003c\/li\u003e\n\u003cli\u003ePart number and wire diameter marked directly on tip for quick identification\u003c\/li\u003e\n\u003cli\u003eCompatible with slip-on and thread-on nozzle styles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Tweco No. 5 MIG guns and compatible Tweco 15H Series MIG gun configurations rated for 200 to 500 amps.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified welders or MIG gun technicians. Always power down the welding machine and allow the gun to cool before replacing contact tips. Thread the tip into the gas diffuser by hand and seat it firmly using the twist-lock mechanism. Inspect the nozzle, diffuser, and liner for wear whenever the contact tip is replaced to maintain consistent arc performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter (Nominal ID)\u003c\/strong\u003e: 0.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter (OD)\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\/16-18 UNC-2A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size Accommodated\u003c\/strong\u003e: 7\/64 inch (0.109 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 500 A\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\u003eMaterial\u003c\/strong\u003e: 122 DHP Copper Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 1150-1211\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346042224946,"sku":"1150-1211","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545846.jpg?v=1782069532","url":"https:\/\/voomisupply.com\/products\/tweco-1150-1211-mig-contact-tip-0-12-bore-1-97-in-500a","provider":"Voomi Supply","version":"1.0","type":"link"}
