This nozzle is part of TWECO's Velocity line, engineered to reduce thread-related service issues common with conventional MIG consumables. Standard MIG nozzle assemblies typically involve two or three sets of threads; the Velocity design reduces this to one. The mating thread pairing combines brass on the nozzle with stainless steel on the gooseneck, a soft-against-hard configuration that resists seizing and cross-threading during routine nozzle changes.\u003c\/p\u003e\u003cp\u003eThis nozzle is suited for medium duty MIG welding in fabrication, maintenance, and repair environments. It installs on compatible TWECO Velocity gooseneck assemblies and is sold individually. The fixed threaded design maintains a consistent flush relationship between the nozzle opening and contact tip, which supports repeatable arc placement and consistent shielding gas coverage. Welders working in production or field settings will find the tool-free nozzle change process reduces downtime during consumable swaps.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-thread design eliminates the two or three thread sets found on conventional MIG nozzles, reducing seizing and cross-threading risk\u003c\/li\u003e\n\u003cli\u003eBrass nozzle threads mate against heat-treated stainless steel gooseneck threads for a soft-on-hard grip that resists loosening\u003c\/li\u003e\n\u003cli\u003eFixed threaded configuration maintains consistent flush relationship between nozzle opening and contact tip\u003c\/li\u003e\n\u003cli\u003e5\/8-inch bore diameter suits medium duty MIG welding applications\u003c\/li\u003e\n\u003cli\u003eTool-free nozzle replacement reduces changeover time during welding operations\u003c\/li\u003e\n\u003cli\u003eSold individually, allowing targeted replacement of worn consumables\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with TWECO Velocity series MIG gun gooseneck assemblies that accept the Velocity2a medium duty nozzle interface.

Disconnect or power down the welding power source and allow the gun to cool before removing a spent nozzle. Thread the replacement nozzle by hand until snug; the brass-on-stainless thread design does not require tools. Inspect the contact tip and liner condition during any nozzle change interval.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuty Level\u003c\/strong\u003e: Medium Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246434490\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: 1240-1866\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51347504333106,"sku":"1240-1866","price":56.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546004.jpg?v=1782107031","url":"https:\/\/voomisupply.com\/products\/tweco-1240-1866-velocity2a-mig-nozzle-5-8-inch-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
