Measuring 1.5 inches in length, it is machined from 122 DHP copper alloy tubing using an extrusion or gun-drill process. This manufacturing method produces a consistent, smooth inside diameter surface held to a tolerance of plus or minus 0.003 inches. The tip features a threaded style with a 1\/4-inch-28 UNF-2A thread and a 1\/4-inch OD, ensuring positive contact with a gas diffuser when installed. Sold in packs of 25, these tips are intended for licensed welding technicians and shop personnel working in standard MIG welding applications.\u003c\/p\u003e\u003cp\u003eThe 1140-1109 is rated for use in standard MIG welding applications up to 400 amps. It is compatible with the Tweco No. 2, No. 3, and No. 4 MIG gun platforms as well as specific Tweco MIG gun series. The thick-walled copper alloy construction acts as a heat sink, drawing heat away from the arc source during extended operation. The tip accepts both slip-on and thread-on nozzle styles, making it suitable for a range of Tweco-compatible MIG gun configurations in light industrial, fabrication, and production welding environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/64-inch wire diameter, 0.090-inch nominal bore ID held to plus or minus 0.003 inches tolerance\u003c\/li\u003e\n\u003cli\u003eMachined from 122 DHP copper alloy for consistent electrical conductivity and smooth wire feed\u003c\/li\u003e\n\u003cli\u003e1\/4-inch-28 UNF-2A threaded style ensures secure, positive contact with gas diffuser\u003c\/li\u003e\n\u003cli\u003eTwist-lock design locks in place with a quarter-turn clockwise; exposes a new wear point to extend tip life\u003c\/li\u003e\n\u003cli\u003eThick-walled design functions as a heat sink to reduce heat buildup at the arc source\u003c\/li\u003e\n\u003cli\u003ePart number and wire diameter marked on each tip for fast field identification\u003c\/li\u003e\n\u003cli\u003eSold as 25 per pack for shop and fleet stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with Tweco No. 2, No. 3, and No. 4 MIG guns as well as specific Tweco MIG gun series.

Power down and allow the MIG gun to cool before removing a spent tip. Use the correct thread engagement when installing the threaded tip into the gas diffuser to avoid cross-threading. Inspect the gas diffuser for wear or spatter buildup at the same time the tip is replaced.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 5\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter (Nominal ID)\u003c\/strong\u003e: 0.090 inches\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\u003eThread Size\u003c\/strong\u003e: 1\/4-28 UNF-2A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 400 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\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUOM\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: 1140-1109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51348023247154,"sku":"1140-1109","price":64.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545765.jpg?v=1782118378","url":"https:\/\/voomisupply.com\/products\/tweco-1140-1109-mig-contact-tip-5-64-in-0-090-bore-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
