The nozzle channels shielding gas around the weld pool to protect the molten metal from atmospheric contamination during the welding process. It accommodates a wire outside diameter range of 0.023 inches minimum to 0.045 inches maximum, making it compatible with common MIG wire sizes used in light fabrication and general repair work. At 0.14 pounds, it is a lightweight component that welding technicians and fabricators replace as part of routine gun maintenance when spatter buildup restricts gas flow or causes arc instability.\u003c\/p\u003e\u003cp\u003eThis gas nozzle is suited for MIG welding applications in fabrication shops, maintenance and repair operations, and light industrial environments. It fits guns used with both solid wire and flux-core wire setups within the stated wire diameter range. Installers typically stock this nozzle as a consumable replacement part to minimize downtime during active welding operations. The compact form factor, measuring approximately 0.85 inches in height and width and 2.23 inches in length, is consistent with standard short-barrel MIG gun nozzle configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire diameter range: 0.023 inches to 0.045 inches (0.58 mm to 1.20 mm)\u003c\/li\u003e\n\u003cli\u003eCompact nozzle dimensions: 0.85 x 0.85 x 2.23 inches for standard MIG gun fitment\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.14 pounds for minimal added gun weight\u003c\/li\u003e\n\u003cli\u003eConsumable replacement design for routine MIG gun maintenance\u003c\/li\u003e\n\u003cli\u003eUNSPSC Code 23271711 for procurement and catalog classification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement MIG welder gas nozzle for guns accepting a wire outside diameter range of 0.023 to 0.045 inches.

Always disconnect the welding machine from its power source and allow the gun to cool completely before removing or installing a nozzle. Thread the nozzle carefully by hand to avoid cross-threading, and inspect the contact tip and liner at the same time for wear. Follow the gun manufacturer guidelines and applicable shop safety procedures during service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Nozzle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Wire Outside Diameter\u003c\/strong\u003e: 0.023 inches (0.58 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Wire Outside Diameter\u003c\/strong\u003e: 0.045 inches (1.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.23 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.85 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.85 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23271711\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRO-SOURCE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21-50F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51731598803250,"sku":"21-50F","price":80.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/258843d0611197ecb89807578bff6049.jpg?v=1788733028","url":"https:\/\/voomisupply.com\/products\/pro-source-21-50f-mig-welder-gas-nozzle","provider":"Voomi Supply","version":"1.0","type":"link"}
