KP23-62 - Lincoln KP23-62 Magnum MIG Gun Nozzle, 5/8-Inch Bore, Fixed Recess

Reliable Performance for Your Magnum MIG Gun

When you are in the middle of a long shift, the last thing you want to worry about is your consumables failing or clogging up constantly. The Lincoln Electric KP23-62 Gas Nozzle is the workhorse replacement for your Magnum 250L, 300, or 400 series MIG gun. Built to handle the heat of 250 to 400 amps, this nozzle is designed for welders who need consistent results day in and day out. The 5/8-inch bore is the "Goldilocks" size for most shop applications—wide enough to give you great gas coverage on fillet and groove welds, but narrow enough to get into reasonably tight corners without snagging.

One of the best features of this nozzle is the fixed recess. If you've ever stuck a contact tip to your work because you got a little too close, you know the frustration. The recessed design keeps your tip set back inside the nozzle, acting as a bumper to prevent those accidental shorts. It also helps keep the tip cooler, which means you aren't stopping to change burned-out tips as often. Plus, the recess helps funnel the shielding gas directly around the wire, stabilizing the arc and reducing porosity in your welds.

Cleanup is straightforward with the KP23-62. The smooth copper alloy surface resists spatter adhesion better than cheaper alternatives, so a quick scrape with your nozzle pliers or a dip in anti-spatter gel is usually all it takes to keep it flowing freely. Whether you are running .035" solid wire for mild steel or bumping up to larger flux-cored or aluminum wires, this nozzle handles wire sizes from .025" all the way up to 5/64". It slides on securely to the insulator, ensuring a tight seal that prevents gas leaks and air aspiration. Keep a few of these in your toolbox so you are never caught without a fresh nozzle when it counts.
