Machined from 360 brass alloy bar stock, it delivers consistent dimensional stability and reliable electrical conductivity across light to medium duty welding cycles. The external surface carries machined threads that allow slip-on nozzle assemblies to seat and lock in place during the weld, and a conduit set screw holds the liner securely. The part number is roll-stamped on the exterior for fast field identification. Each order is sold as a pack of 5 units.\u003c\/p\u003e\u003cp\u003eThis gas diffuser is engineered for use with slip-on nozzle assemblies on the Tweco No. 3 and No. 4 MIG gun series, as well as Tweco Eliminator front-end consumable systems. It suits standard welding setups in fabrication shops, production lines, and field welding environments where duty cycles demand a reliable gas flow path at currents up to 450 A. The fixed-nozzle design works with both threaded and slip-on nozzle configurations, making it a versatile fit across multiple front-end assemblies in the Tweco platform.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated for welding applications up to 450 amperes\u003c\/li\u003e\n\u003cli\u003eMachined from 360 brass alloy bar stock for consistent dimensional stability and strong electrical conductivity\u003c\/li\u003e\n\u003cli\u003eMachined external threads allow slip-on nozzle assemblies to thread over and lock in place during welding\u003c\/li\u003e\n\u003cli\u003eConduit set screw secures the conduit liner in position\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on exterior surface for quick field identification\u003c\/li\u003e\n\u003cli\u003eSold as a 5-unit pack for efficient consumable stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with slip-on nozzle assemblies on Tweco No. 3 and No. 4 MIG gun series and Tweco Eliminator front-end consumable systems.

Before servicing front-end consumables, power down the welder and allow the gun and nozzle assembly to cool completely. Thread the nozzle assembly over the diffuser and tighten the conduit set screw to secure the liner before resuming operation. Follow the gun manufacturer's service guidelines and applicable workplace safety standards when replacing consumable components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 450 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 360 brass alloy bar stock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Fixed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246079585\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: 1520-1102\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346314690866,"sku":"1520-1102","price":112.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546125.jpg?v=1782077227","url":"https:\/\/voomisupply.com\/products\/tweco-1520-1102-mig-gas-diffuser-450a-brass-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
