It measures 1.5 inches in length and is machined from 122 DHP copper alloy tubing, providing a consistent, smooth inside diameter surface held to a tolerance of plus or minus 0.003 inches. The threaded style tip uses a 1\/4 inch-28 UNF-2A thread and features a 1\/4 inch OD. A licensed welding professional or MIG gun technician installs this tip as part of routine consumable maintenance on MIG welding guns rated up to 400 amps. Sold in packs of 25.\u003c\/p\u003e\n\u003cp\u003eThis contact tip is rated for standard MIG welding applications up to 400 amps. It is compatible with 200 to 400 amp Tweco No. 2, No. 3, and No. 4 MIG guns as well as specific Tweco MIG gun series. The tip works with both slip-on and thread-on nozzle styles. The thick-walled copper alloy construction acts as a heat sink, drawing heat away from the arc source during continuous welding operations. The part number and wire diameter are marked directly on the tip for quick identification in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.038 inch nominal bore diameter with plus or minus 0.003 inch ID tolerance for consistent wire feed\u003c\/li\u003e\n  \u003cli\u003eMachined from 122 DHP extruded or gun-drilled copper alloy for smooth, uniform inside surface\u003c\/li\u003e\n  \u003cli\u003eTwist-lock design secures tip in place against the gas diffuser without relying on threads alone\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 design conducts heat away from the arc source, extending tip longevity\u003c\/li\u003e\n  \u003cli\u003ePart number and wire diameter marked on each tip for easy field identification\u003c\/li\u003e\n  \u003cli\u003eSold as 25 per pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with 200 to 400 amp Tweco No. 2, No. 3, and No. 4 MIG guns, as well as specific Tweco MIG gun series.

Always power down the welder and allow the gun to cool before removing a worn tip. Use the twist-lock engagement to seat the tip fully against the gas diffuser, and confirm the nozzle style (slip-on or thread-on) matches the gun configuration before installation. Follow the equipment manufacturer's service guidelines and applicable workplace safety standards when servicing MIG gun consumables.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter (Nominal ID)\u003c\/strong\u003e: 0.038 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\u003eLength\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 inch-28 UNF-2A\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: 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\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1140-1101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51345951359282,"sku":"1140-1101","price":62.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545769.jpg?v=1782067296","url":"https:\/\/voomisupply.com\/products\/tweco-1140-1101-mig-contact-tip-0-030-in-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
