It accommodates 0.045-inch wire with a 0.054-inch nominal bore and measures 1.5 inches in length. The tip is machined from extruded or gun-drilled 122 DHP copper alloy tubing, delivering a consistent, smooth inside diameter held to a tolerance of plus or minus 0.003 inches. The M8 x 1.25-6g thread style ensures secure, consistent contact with the gas diffuser. Each tip is clearly marked with part number and wire diameter for fast field identification. Sold in packs of 25.\u003c\/p\u003e\u003cp\u003eThis contact tip is rated for heavy-duty welding up to 600 amps and is compatible with Tweco Spray Master and Tweco No. 6 MIG guns, as well as specific MIG gun series in that current range. It suits both slip-on and thread-on nozzle configurations. The thick-walled copper alloy construction acts as a heat sink, drawing heat away from the arc source during sustained high-amperage operation. Ideal for professional welding environments where tip longevity and consistent arc quality are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.045-inch wire diameter, 0.054-inch nominal bore with plus or minus 0.003-inch ID tolerance\u003c\/li\u003e\n\u003cli\u003eRated for welding applications up to 600 amps\u003c\/li\u003e\n\u003cli\u003eMachined from 122 DHP copper alloy for excellent electrical conductivity and smooth bore surface\u003c\/li\u003e\n\u003cli\u003eTwist-lock design secures tip to diffuser without thread engagement, increasing electrical contact surface area\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 functions as a heat sink to conduct heat away from the arc\u003c\/li\u003e\n\u003cli\u003ePart number and wire diameter marked on each tip for easy identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with Tweco Spray Master and Tweco No. 6 MIG guns rated 350 to 600 amps, as well as specific MIG gun series designed for use with 16 Series consumables.

Power down and disconnect the welding machine before replacing the contact tip. Thread the tip onto the gas diffuser using the M8 x 1.25-6g thread and twist to lock securely before resuming operation. When the active wear point is reached, twist a quarter turn clockwise to expose a fresh wear surface rather than replacing the tip immediately.\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: 0.054 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOD\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8 x 1.25-6g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 600 amps maximum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 122 DHP copper alloy\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\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: 1160-1137\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344948789554,"sku":"1160-1137","price":125.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545834.jpg?v=1782046519","url":"https:\/\/voomisupply.com\/products\/tweco-1160-1137-mig-contact-tip-0-045-in-0-054-bore-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
