Machined from 122 DHP copper alloy tubing, it delivers consistent electrical conductivity and a smooth internal bore surface. The tip accommodates 1\/16-inch wire with a nominal inside diameter of 0.073 inches and an outside diameter of 0.283 inches. The inside diameter tolerance is held to plus or minus 0.003 inches for reliable wire feed and arc stability. At 1.47 inches in length with a 1\/4-28 UNF-2A thread, this tip is installed and serviced quickly by welding technicians in production and field environments.\u003c\/p\u003e\u003cp\u003eThis contact tip is suited for heavy-duty MIG welding operations in industrial, fabrication, and manufacturing settings. It is rated for use up to 400 amps, making it appropriate for high-amperage continuous or semi-continuous welding cycles. The threaded design ensures firm, consistent contact with the gas diffuser when mounted to a MIG welding gun. Each tip is marked with the part number and wire diameter for fast identification during changeovers. Sold in packs of 25, this tip is a standard consumable for shops running high-volume weld operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated up to 400 amps for heavy-duty MIG welding applications\u003c\/li\u003e\n\u003cli\u003eMachined from 122 DHP copper alloy for excellent electrical conductivity\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance held to plus or minus 0.003 inches for consistent wire feed\u003c\/li\u003e\n\u003cli\u003e1\/4-28 UNF-2A threaded style ensures proper seating against gas diffuser\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 units per pack for convenient consumable stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a heavy-duty replacement contact tip for MIG welding guns accepting 1\/4-28 UNF-2A threaded tips and 1\/16-inch wire diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eContact tips are installed and replaced by welding technicians as a routine consumable service. Always power down the welding machine and allow the gun to cool before removing a spent tip. Use the appropriate tip wrench or pliers to avoid damaging the gas diffuser threads.
