Part of the Tweco 15H series, it accepts 0.062 inch (5\/64 inch) wire diameter and features a 0.090 inch nominal bore ID with a tolerance held to plus or minus 0.003 inches. The tip measures 1.97 inches in length and is machined from 122 DHP copper alloy tubing, providing a consistent, smooth inside diameter surface with excellent electrical conductivity. A licensed welding technician or fabricator typically installs this consumable as part of routine MIG gun maintenance.\u003c\/p\u003e\u003cp\u003eThis contact tip is rated for use with 200 to 500 amp Tweco No. 5 MIG guns and compatible heavy-duty MIG gun series. Its threaded design uses a 5\/16 inch-18 UNC-2A thread for secure engagement with the gas diffuser. The tip supports both slip-on and thread-on nozzle styles. It is sold in packs of 25, making it well suited for high-volume production welding environments or service fleets that cycle through consumables regularly. The 0.345 inch OD and thick-walled construction make it appropriate for demanding, continuous-duty welding cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated up to 500 amps for heavy-duty MIG welding applications\u003c\/li\u003e\n\u003cli\u003eMachined from 122 DHP extruded or gun-drilled copper alloy for consistent bore surface\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance held to plus or minus 0.003 inches for reliable wire feed\u003c\/li\u003e\n\u003cli\u003eTwist-lock design engages gas diffuser without loose threading concerns\u003c\/li\u003e\n\u003cli\u003eQuarter-turn clockwise rotation reveals a new wear point, effectively doubling tip service life\u003c\/li\u003e\n\u003cli\u003eThick-walled construction acts as a heat sink, conducting heat away from the arc source\u003c\/li\u003e\n\u003cli\u003ePart number and wire diameter marked on each tip for easy field identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with 200 to 500 amp Tweco No. 5 MIG guns and specific compatible MIG gun series.

Power down and disconnect the welding machine before servicing the gun head. Ensure the replacement tip is fully seated and locked against the gas diffuser before resuming operation. Do not overtighten threaded tips; hand-tight engagement followed by a quarter-turn is the general practice for this tip style.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.062 inches (5\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore ID\u003c\/strong\u003e: 0.090 inches nominal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Tolerance\u003c\/strong\u003e: plus or minus 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOD\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 maximum\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 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: 1150-1209\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344845570354,"sku":"1150-1209","price":140.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545785.jpg?v=1782044562","url":"https:\/\/voomisupply.com\/products\/tweco-1150-1209-mig-contact-tip-0-062-in-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
