Machined from 145 tellurium copper alloy bar stock, it delivers consistent dimensional stability and reliable electrical conductivity across medium to heavy-duty welding cycles. The diffuser measures 1.375 inches in overall length and features a 7\/16 inch-20UNF-2A thread for secure mounting to the conductor tube. Six 0.094 inch gas holes distribute shielding gas evenly around the weld zone. A conduit set screw holds the 1\/16 inch conduit liner securely in place during operation. The part number is roll-stamped on the external surface for fast identification in the field. Sold in a pack of 5. Licensed welders and MIG gun service technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis diffuser is rated for welding applications up to 500 amps, making it appropriate for medium to heavy-duty fabrication, structural, and manufacturing environments. It is compatible with the Tweco No. 5 MIG gun series and Eliminator front-end consumable systems. The tellurium copper construction maintains dimensional accuracy under sustained high-amperage heat cycles, reducing tip drift and inconsistent gas coverage over long runs. It suits production environments where consistent arc performance and minimal consumable downtime are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated up to 500 A for medium to heavy-duty MIG welding applications\u003c\/li\u003e\n\u003cli\u003eMachined from 145 tellurium copper alloy bar stock for consistent dimensional stability\u003c\/li\u003e\n\u003cli\u003eSix 0.094 inch gas holes for even shielding gas distribution\u003c\/li\u003e\n\u003cli\u003e7\/16 inch-20UNF-2A thread for secure conductor tube connection\u003c\/li\u003e\n\u003cli\u003eConduit set screw accommodates 1\/16 inch conduit liner\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on exterior surface for quick field identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with the Tweco No. 5 MIG gun series and Eliminator front-end consumable systems for standard-duty welding setups rated up to 500 A.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified welders or MIG equipment technicians. Disconnect power to the welding system and allow the gun to cool completely before replacing front-end consumables. Thread the diffuser onto the conductor tube by hand first to avoid cross-threading, then snug with appropriate tooling. Verify the conduit liner is fully seated and secured by the set screw before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 Holes\u003c\/strong\u003e: Six at 0.094 inches each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConduit Liner Size\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 500 A\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: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Pack of 5\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: 1550-1101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51343669395762,"sku":"1550-1101","price":93.58,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546152.jpg?v=1782023737","url":"https:\/\/voomisupply.com\/products\/tweco-1550-1101-gas-diffuser-1-375-inch-500a-mig","provider":"Voomi Supply","version":"1.0","type":"link"}
