It directs shielding gas flow around the weld pool to protect the arc from atmospheric contamination. The fixed recessed geometry positions the contact tip setback from the nozzle face, reducing spatter buildup and improving access in tight joint configurations. Rated for use at 100 to 175 amps, this nozzle suits light to medium-duty MIG welding applications. It is installed and serviced by welding technicians and maintenance professionals working with Lincoln water-cooled MIG gun systems.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is suited for water-cooled MIG gun setups in shop fabrication, light manufacturing, and maintenance welding environments. The water-cooled design allows the gun and nozzle assembly to handle sustained duty cycles without the heat buildup associated with air-cooled torches. The fixed recessed configuration is a common choice for flat and horizontal welds where tip protection and consistent gas coverage are priorities. It ships as a single unit, making it practical for one-for-one replacement during scheduled maintenance or unplanned downtime.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFixed recessed nozzle geometry reduces spatter accumulation on the contact tip\u003c\/li\u003e\n  \u003cli\u003eWater-cooled construction supports sustained duty cycles in production welding\u003c\/li\u003e\n  \u003cli\u003e0.375 inch bore diameter provides consistent shielding gas distribution\u003c\/li\u003e\n  \u003cli\u003eRated for 100 to 175 amp operation\u003c\/li\u003e\n  \u003cli\u003eDirect OEM-style fit for compatible Lincoln Electric MIG gun platforms\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging allows straightforward one-for-one field replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Lincoln Electric MIG welding equipment.

Inspect the water-cooling passages and gas diffuser for blockage or damage during the nozzle change. Hand-tighten the nozzle to the recommended snug fit without over-torquing, which can damage the gun body threads. Follow the equipment manufacturer's service procedures and applicable workplace safety standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Fixed Recessed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCooling Method\u003c\/strong\u003e: Water Cooled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Range\u003c\/strong\u003e: 100 to 175 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: KP21T-37\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LINCOLN ELECTRIC","offers":[{"title":"Default Title","offer_id":51560371880242,"sku":"KP21T-37","price":42.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0da938415b6afaca006260f146a07743.jpg?v=1786451870","url":"https:\/\/voomisupply.com\/products\/lincoln-electric-kp21t-37-mig-welder-nozzle-water-cooled","provider":"Voomi Supply","version":"1.0","type":"link"}
