Machined from extruded or gun-drilled copper alloy tubing, it delivers consistent electrical conductivity and a smooth inside diameter surface. The inside diameter tolerance is held to plus or minus 0.003 inches, ensuring reliable wire feed and arc stability. This tip is rated for heavy-duty welding applications up to 200 amperes and is compatible with threaded and Eliminator twist-lock style gas diffusers. Each tip is marked with the part number and wire diameter for fast field identification.\u003c\/p\u003e\u003cp\u003eThis contact tip is intended for professional MIG welding applications where consistent wire-to-tip contact is critical. It suits both production and field welding environments handling 1\/16-inch wire diameter. The tapered profile fits threaded-style and Eliminator twist-lock gas diffuser configurations, making it a versatile consumable for welders running compatible TWECO MIG gun setups. Licensed welding professionals and maintenance technicians performing structural, fabrication, or heavy-duty welding work will find this tip suited to demanding, high-amperage applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCopper alloy construction machined from extruded or gun-drilled tubing for consistent inside diameter 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\u003eRated for heavy-duty welding applications up to 200 amperes\u003c\/li\u003e\n\u003cli\u003eCompatible with threaded-style and Eliminator twist-lock gas diffusers\u003c\/li\u003e\n\u003cli\u003eEach tip marked with part number and wire diameter for easy identification\u003c\/li\u003e\n\u003cli\u003eTapered profile designed for proper seating and electrical contact with the gas diffuser\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Eliminator style gas diffusers and threaded-style gas diffusers on compatible TWECO MIG gun series.

Always power down the welding machine and allow the gun to cool before removing or installing consumables. Hand-tighten threaded tips firmly to ensure full electrical contact with the gas diffuser — do not overtighten with tools, as this can damage the diffuser threads. Inspect the gas diffuser for spatter buildup before installing a new tip to maintain proper gas flow and arc quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Style\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 200 amperes\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: Copper alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246288420\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: 1160-1139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51342962688306,"sku":"1160-1139","price":125.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545832.jpg?v=1782012059","url":"https:\/\/voomisupply.com\/products\/tweco-1160-1139-tapered-contact-tip-1-16-inch-mig","provider":"Voomi Supply","version":"1.0","type":"link"}
