Machined from 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 inside diameter is 0.059 inches with an outside diameter of 0.283 inches and a body length of 1.47 inches. The 1\/4 inch-28 UNF-2A thread ensures secure, positive contact with the gas diffuser on a MIG gun. Each tip is marked with the part number and wire diameter for fast field identification. Sold in packs of 25.\u003c\/p\u003e\u003cp\u003eThis contact tip is suited for standard MIG welding operations in both shop and field environments. It is rated for continuous use up to 400 amps, making it appropriate for light industrial and production welding applications. The threaded design is compatible with MIG guns that accept the standard 1\/4 inch-28 UNF-2A tip thread. Welders and maintenance technicians working with flux-core or solid wire processes in the 0.046 inch diameter range will find this tip a direct fit for high-cycle production work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMachined from 122 DHP copper alloy tubing for consistent electrical properties and smooth 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\u003e1\/4 inch-28 UNF-2A threaded style ensures proper seating against the gas diffuser\u003c\/li\u003e\n\u003cli\u003eEach tip marked with part number and wire diameter for quick identification\u003c\/li\u003e\n\u003cli\u003eRated up to 400 amps for standard MIG welding applications\u003c\/li\u003e\n\u003cli\u003eSold as a pack of 25 for high-volume or production use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for MIG guns that accept a 1\/4 inch-28 UNF-2A threaded contact tip and use 0.046 inch wire diameter.

Always power down and de-energize the welding system before replacing a contact tip. Thread the tip by hand into the gas diffuser until snug, then tighten with the appropriate wrench — avoid overtightening, which can crack the tip or distort the bore. Inspect the gas diffuser threads before installation to ensure a clean, undamaged seating surface.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.046 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore (Nominal ID)\u003c\/strong\u003e: 0.059 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.283 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Length\u003c\/strong\u003e: 1.47 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch-28 UNF-2A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 400 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter 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\u003eQuantity per Pack\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 1140-1248\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51345439326514,"sku":"1140-1248","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545797.jpg?v=1782058247","url":"https:\/\/voomisupply.com\/products\/tweco-1140-1248-mig-contact-tip-0-046-in-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
