Machined from 145 tellurium copper alloy bar stock, this diffuser delivers consistent dimensional stability and reliable electrical conductivity across medium to heavy-duty welding applications. It measures 1.375 inches in overall length and features six 0.094-inch gas holes that promote even shielding gas distribution across the weld zone. A 7\/16-inch-20UNF-2A thread size matches the corresponding conductor tube on compatible MIG guns. The part number is roll-stamped on the external surface for quick identification in the field. Sold as 5 per pack.\u003c\/p\u003e\n\u003cp\u003eThis gas diffuser is suited for medium to heavy-duty MIG welding applications rated up to 500A. It is compatible with Tweco No. 3 and No. 4 MIG gun series that use slip-on nozzle assemblies, as well as Tweco Eliminator front-end consumables. The diffuser accommodates a conduit liner via a built-in conduit set screw, making it a practical replacement component in production welding environments and job-site MIG setups where consistent gas coverage and electrical performance are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMachined from 145 tellurium copper alloy bar stock for consistent dimensional stability and electrical conductivity\u003c\/li\u003e\n  \u003cli\u003eSix 0.094-inch gas holes provide even shielding gas distribution at the weld zone\u003c\/li\u003e\n  \u003cli\u003e7\/16-inch-20UNF-2A thread mates with conductor tube on compatible MIG gun series\u003c\/li\u003e\n  \u003cli\u003eConduit set screw holds the conduit liner securely in position\u003c\/li\u003e\n  \u003cli\u003ePart number roll-stamped on external surface for fast identification during consumable changeouts\u003c\/li\u003e\n  \u003cli\u003eRated for welding applications up to 500A for medium to heavy-duty use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with Tweco No. 3 and No. 4 MIG gun series using slip-on nozzle assemblies, and with Tweco Eliminator front-end consumable systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGas diffuser replacement is a standard consumable service task performed by certified welders or MIG gun technicians. Power down and de-energize the welding system completely before replacing front-end consumables. Thread the diffuser onto the conductor tube by hand first, then snug to the specified conductor tube interface to avoid cross-threading. Ensure the conduit liner is seated and secured by the conduit set screw before resuming operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16 inch-20UNF-2A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Hole Size\u003c\/strong\u003e: 0.094 inches (6 holes)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 500A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 145 Tellurium Copper Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246079998\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: 1550-1100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346314887474,"sku":"1550-1100","price":95.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546135.jpg?v=1782077234","url":"https:\/\/voomisupply.com\/products\/tweco-1550-1100-mig-gas-diffuser-1-375-in-500a","provider":"Voomi Supply","version":"1.0","type":"link"}
