At 1.5 inches in length, it is machined from extruded or gun-drilled 122 DHP copper alloy tubing, delivering a consistent, smooth inside diameter held to plus or minus 0.003 inches tolerance. The thick-walled construction acts as a heat sink, drawing heat away from the arc source. This contact tip carries an M8 x 1.25-6g thread and a 0.375-inch OD. It is installed and serviced by certified welders and MIG gun technicians working in heavy-duty industrial and fabrication environments rated up to 600 amps.\u003c\/p\u003e\n\u003cp\u003eThis tip is suited for heavy-duty MIG welding applications up to 600 amps. It is compatible with Tweco Spray Master 350-600 A MIG guns and Tweco No. 6 MIG guns, as well as specific compatible MIG gun series. The twist-lock design engages the gas diffuser without relying on threads alone, increasing the electrical contact surface area between the tip and diffuser. When the active wear point is reached, a quarter-turn clockwise rotation exposes a new wear point, effectively doubling service life before replacement is needed. Sold in packs of 25, this tip is a practical consumable for high-volume welding operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.048-inch nominal bore for 0.040-inch wire with inside diameter tolerance held to plus or minus 0.003 inches\u003c\/li\u003e\n  \u003cli\u003eMachined from 122 DHP copper alloy for excellent electrical conductivity and thermal performance\u003c\/li\u003e\n  \u003cli\u003eThick-walled design acts as a heat sink, conducting heat away from the arc source\u003c\/li\u003e\n  \u003cli\u003eTwist-lock engagement increases electrical contact surface area with the gas diffuser\u003c\/li\u003e\n  \u003cli\u003eQuarter-turn clockwise rotation reveals a second wear point, doubling tip life\u003c\/li\u003e\n  \u003cli\u003ePart number and wire diameter marked on each tip for quick field identification\u003c\/li\u003e\n  \u003cli\u003eSold as 25 per pack for high-volume consumable restocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Tweco Spray Master 350-600 A MIG guns and Tweco No. 6 MIG guns, as well as specific compatible MIG gun series.

Power down and de-energize the welding system before servicing the contact tip. Ensure the tip is fully seated and twist-locked against the gas diffuser to maintain proper electrical contact. Inspect the bore and wear point regularly and rotate to the second wear position before discarding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore (Nominal ID)\u003c\/strong\u003e: 0.048 inches\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\u003eOutside Diameter\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\u003eMaterial\u003c\/strong\u003e: 122 DHP Copper Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 600 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: 25 per pack\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: 1160-1103\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51345855578418,"sku":"1160-1103","price":108.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545817.jpg?v=1782064735","url":"https:\/\/voomisupply.com\/products\/tweco-1160-1103-mig-contact-tip-0-040-in-16-series-heavy-duty","provider":"Voomi Supply","version":"1.0","type":"link"}
