It is machined from extruded or gun-drilled 122 DHP copper alloy tubing, which produces a consistent, smooth inside diameter with a tolerance held to plus or minus 0.003 inches. The nominal inside diameter is 0.054 inches and the outside diameter is 0.345 inches. At 1.97 inches in length with a 5\/16-18 UNC-2A thread, this tip is rated for heavy-duty welding applications up to 500 amps. It is sold in packs of 25 and installed by welders and MIG gun technicians servicing high-amperage wire welding equipment.\u003c\/p\u003e\u003cp\u003eThis contact tip is intended for use with 200-500 amp Tweco No. 5 MIG guns and compatible MIG gun series requiring a threaded-style contact tip. It fits applications where slip-on or thread-on nozzle styles are used. The tip works in heavy industrial and fabrication environments where sustained high-amperage output demands reliable current transfer and extended consumable life. The twist-lock design and dual wear-point feature make it well suited for production welding operations where downtime for tip changes must be minimized.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMachined from 122 DHP copper alloy for consistent inside diameter surface and excellent electrical conductivity\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance held to plus or minus 0.003 inches for reliable wire feed and arc stability\u003c\/li\u003e\n\u003cli\u003e5\/16-18 UNC-2A thread ensures secure seating and proper contact with gas diffuser\u003c\/li\u003e\n\u003cli\u003eTwist-lock design locks tip in place and increases contact surface area between tip and diffuser\u003c\/li\u003e\n\u003cli\u003eQuarter-turn clockwise rotation reveals a second wear point, effectively doubling tip service life\u003c\/li\u003e\n\u003cli\u003eThick-walled construction acts as a heat sink, drawing heat away from the arc source\u003c\/li\u003e\n\u003cli\u003eEach tip is marked with part number and wire diameter for fast, accurate identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Tweco No. 5 MIG guns rated 200-500 amps and compatible MIG gun series accepting a 5\/16-18 UNC-2A threaded contact tip for 0.045-inch wire diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eContact tips are installed and serviced by qualified welders or MIG gun technicians. Always power down the welding machine and allow the gun to cool before replacing contact tips. Thread the tip in by hand until snug, then engage the twist-lock by rotating clockwise — do not use excessive force. Inspect the gas diffuser for wear or spatter buildup before installing a new tip, as a damaged diffuser will shorten tip life.\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\u003eNominal Bore (ID)\u003c\/strong\u003e: 0.054 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter (OD)\u003c\/strong\u003e: 0.345 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.97 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC-2A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: Up to 500 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\u003eID Tolerance\u003c\/strong\u003e: plus or minus 0.003 inches\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: 0.05 pounds\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: 1150-1204\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51345140941106,"sku":"1150-1204","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545796.jpg?v=1782050175","url":"https:\/\/voomisupply.com\/products\/tweco-1150-1204-mig-contact-tip-0-045-in-1-97-in-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
