Designed to accommodate 0.045-inch wire, this tip features a 0.051-inch nominal inside diameter bore and measures 1.47 inches in length. The tip is machined from chrome zirconium 1815 alloy copper tubing, which is harder than standard copper alloy material, delivering greater wear resistance and extended tip life. The inside diameter is held to a tolerance of plus or minus 0.003 inches, producing a consistent, smooth bore surface for stable arc performance. Sold in packs of 25.\u003c\/p\u003e\u003cp\u003eThis contact tip is suited for robotic and automated MIG welding systems operating in high-amperage, continuous-duty environments. The 1\/4-inch-28 UNF-2A threaded style ensures positive engagement with a gas diffuser when installed to the MIG gun. Each tip is marked with the part number and wire diameter for fast identification during changeovers. Typical applications include fabrication shops, production welding lines, and any operation demanding higher tip durability than standard copper alloy tips can provide.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAccommodates 0.045-inch wire with a 0.051-inch nominal bore\u003c\/li\u003e\n\u003cli\u003eChrome zirconium 1815 alloy construction — harder than standard copper alloy for increased wear resistance\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance held to plus or minus 0.003 inches for consistent arc performance\u003c\/li\u003e\n\u003cli\u003e1\/4-inch-28 UNF-2A threaded style ensures proper seating on gas diffuser\u003c\/li\u003e\n\u003cli\u003ePart number and wire diameter marked on each tip for easy field identification\u003c\/li\u003e\n\u003cli\u003eRated for welding applications up to 400 amps\u003c\/li\u003e\n\u003cli\u003eSold as a pack of 25\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with MIG guns that accept a 1\/4-inch-28 UNF-2A threaded contact tip and accommodate 0.045-inch welding wire in robotic or standard heavy-duty welding setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eContact tip replacement is performed by qualified welding technicians or maintenance personnel. Always de-energize the welding power source and allow the gun to cool before handling consumables. Thread the tip into the gas diffuser by hand first, then snug with appropriate pliers or a tip wrench — do not overtighten. Inspect the gas diffuser for spatter buildup during each tip change to maintain shielding gas flow.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.045 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore (Nominal ID)\u003c\/strong\u003e: 0.051 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\u003eLength\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\u003eID Tolerance\u003c\/strong\u003e: plus or minus 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 400 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Chrome Zirconium 1815 Alloy Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 25\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: 1140-1432\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51345959321906,"sku":"1140-1432","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545843.jpg?v=1782067572","url":"https:\/\/voomisupply.com\/products\/tweco-1140-1432-mig-contact-tip-0-045-in-0-051-bore-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
