At 1.5 inches in length, this tip is machined from 122 DHP copper alloy using extruded or gun-drilled tubing to deliver a consistent, smooth inside diameter held to a tolerance of plus or minus 0.003 inches. The thick-walled construction acts as a heat sink, drawing heat away from the arc source. Rated for use up to 400 amps, it carries a 1\/4-inch-28 UNF-2A thread profile and a 1\/4-inch OD. Each tip is marked with part number and wire diameter for fast identification on the job. Sold in packs of 25.\u003c\/p\u003e\u003cp\u003eThis contact tip is suited for standard MIG welding applications up to 400 amps. It is compatible with Tweco No. 2, No. 3, and No. 4 MIG guns rated in the 200 to 400 amp range, as well as compatible Tweco MIG gun series that accept 14 Series consumables. The threaded style ensures solid contact with the gas diffuser when seated in the gun. It accommodates both slip-on and thread-on nozzle configurations, making it adaptable across common Tweco torch setups used in fabrication, maintenance, and production welding environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.052-inch wire size with 0.064-inch nominal bore and plus or minus 0.003-inch ID tolerance\u003c\/li\u003e\n\u003cli\u003eMachined from 122 DHP copper alloy for consistent bore surface and excellent electrical conductivity\u003c\/li\u003e\n\u003cli\u003eThick-walled design acts as a heat sink to conduct heat away from the arc\u003c\/li\u003e\n\u003cli\u003eTwist-lock design locks tip in place against the gas diffuser without relying solely on threads\u003c\/li\u003e\n\u003cli\u003eQuarter-turn clockwise rotation reveals a new wear point, effectively doubling tip service life\u003c\/li\u003e\n\u003cli\u003ePart number and wire diameter marked on each tip for quick identification\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 operating in the 200 to 400 amp range, and other Tweco MIG gun series designed to accept 14 Series standard-duty contact tips.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eContact tip installation and replacement is performed by welders and MIG gun technicians. Always de-energize the welding power source and allow the gun to cool before servicing consumables. Thread the tip fully into the gas diffuser by hand, then seat it using the twist-lock method to ensure proper electrical contact. Inspect the bore diameter for wear and rotate a quarter turn clockwise to expose a fresh wear point before replacing the tip entirely.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.052 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter (Nominal ID)\u003c\/strong\u003e: 0.064 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\u003eTip Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.25 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\u003eCurrent Rating\u003c\/strong\u003e: 400 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\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: 25 per pack\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: 1140-1105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344669868338,"sku":"1140-1105","price":62.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545767.jpg?v=1782039807","url":"https:\/\/voomisupply.com\/products\/tweco-1140-1105-mig-contact-tip-0-052-in-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
