It accommodates 0.030-inch wire with a 0.038-inch nominal bore ID and measures 1.5 inches in length. Machined from extruded or gun-drilled 122 DHP copper alloy tubing, it delivers a consistent, smooth inside diameter surface held to a tolerance of plus or minus 0.003 inches. The thick-walled design acts as a heat sink, conducting heat away from the arc source. Sold in packs of 25, this tip is a direct-use consumable for professional MIG welding operations.\u003c\/p\u003e\u003cp\u003eThis contact tip is suited for standard MIG welding in both production and repair environments. It is rated for use with 200 to 400 amp Tweco No. 2, No. 3, and No. 4 MIG guns, as well as compatible MIG gun series within that amp range. The 1\/4-28 UNF-2A threaded style ensures proper seating against a gas diffuser. The tip accepts slip-on or thread-on nozzle styles and is compatible with standard copper-alloy diffuser configurations. Each tip is marked with the part number and wire diameter for quick identification during changeover.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.030-inch wire diameter, 0.038-inch nominal bore ID with plus or minus 0.003-inch tolerance\u003c\/li\u003e\n\u003cli\u003e1\/4-28 UNF-2A thread with 1\/4-inch OD for secure diffuser engagement\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 draw heat away from the arc\u003c\/li\u003e\n\u003cli\u003eTwist-lock design locks tip in place and increases electrical contact surface area against the diffuser\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 fast identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 200 to 400 amp Tweco No. 2, No. 3, and No. 4 MIG guns, as well as compatible MIG gun series in that amperage range.

Power down and de-energize the MIG gun completely before replacing the contact tip. Thread the tip into the gas diffuser by hand and snug it with appropriate pliers — do not overtighten, as this can damage the diffuser threads. Ensure the nozzle is reinstalled and seated before resuming welding operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore ID (Nominal)\u003c\/strong\u003e: 0.038 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\u003eLength\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOD\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\u003eAmperage Rating\u003c\/strong\u003e: up to 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\u003ePack Quantity\u003c\/strong\u003e: 25 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: 1140-1301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51347648479538,"sku":"1140-1301","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545798.jpg?v=1782110487","url":"https:\/\/voomisupply.com\/products\/tweco-1140-1301-mig-contact-tip-0-030-in-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
