It serves as an insulating component between the nozzle and the contact tip assembly, protecting the gun body from spatter buildup and heat transfer during the welding process. This part accommodates wire outside diameters up to 0.500 inches and is packaged as a single unit. MIG welding technicians and fabrication professionals install this component as a routine consumable replacement to maintain clean, consistent arc performance and extend the service life of the welding gun assembly.\u003c\/p\u003e\u003cp\u003eThis insulator is suited for MIG welding setups in both shop and field environments. It is a direct-replacement consumable used during standard gun maintenance intervals, particularly when spatter accumulation or heat damage compromises the existing insulator. The part ships in a quantity of one and is appropriate for professional welding operations where maintaining proper torch geometry and electrical isolation between components is critical to weld quality.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAccepts wire outside diameters up to 0.500 inches\u003c\/li\u003e\n\u003cli\u003eSingle-unit packaging for individual replacement needs\u003c\/li\u003e\n\u003cli\u003eDesigned for MIG welding gun assemblies\u003c\/li\u003e\n\u003cli\u003eProvides electrical insulation between nozzle and contact tip components\u003c\/li\u003e\n\u003cli\u003eCompact form factor: 3.75 inches tall, 1.88 inches wide, 1 inch in length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insulator for MIG welding gun assemblies requiring a nozzle tip insulator with up to 0.500 inch maximum wire outside diameter compatibility.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified MIG welding technicians as part of routine torch consumable maintenance. Always disconnect the welding machine from its power source and allow the gun to cool completely before removing or replacing nozzle components. Use appropriate hand tools to avoid damaging the contact tip or diffuser threads during removal. Follow the gun manufacturer's assembly sequence when reinstalling the insulator to ensure proper electrical isolation and nozzle alignment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Wire Outside Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LINCOLN ELECTRIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KH725\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LINCOLN ELECTRIC","offers":[{"title":"Default Title","offer_id":51558687375666,"sku":"KH725","price":44.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78bf680f9c3667ab5485632676f918ea.jpg?v=1786417956","url":"https:\/\/voomisupply.com\/products\/lincoln-electric-kh725-mig-welder-nozzle-tip-insulator","provider":"Voomi Supply","version":"1.0","type":"link"}
