KP23-37-B25 - Lincoln Electric Gas Nozzle, Fixed Recess, 0.38 Inch ID (25-Pack)

Keep Your Magnum Gun Running Smoothly

Every welder knows that the nozzle is the first line of defense on your MIG gun. It takes the heat, the spatter, and the abuse so the rest of your gun doesn't have to. The Lincoln Electric KP23-37-B25 is the standard replacement gas nozzle for your Magnum 250LX, 300, or 400 series MIG gun. If you are running one of these workhorses, this 25-pack is exactly what you need in your tool crib. These nozzles feature a fixed recess, meaning your contact tip sits safely back inside the cup. This is great for preventing those accidental arc-outs when you get too close to the metal, and it helps keep your tip cleaner for longer by shielding it from the direct splash of the weld puddle.

The 0.38-inch (9.7 mm) opening is a versatile size. It's tight enough to get you into some restricted spots where a bulky nozzle would get hung up, but it still flows enough gas to keep your porosity in check on standard steel applications. Whether you are running .035 solid wire or heavier flux-cored wire up to 5/64 inch, this nozzle handles the heat. It is rated for up to 400 amps, so you can crank up the voltage for spray transfer without worrying about the nozzle melting down on you halfway through a pass.

Why buy the 25-pack? Because nozzles are consumables, and running around looking for a spare when yours is clogged with spatter kills your rhythm and your paycheck. With this bulk pack, you can swap out a beat-up nozzle for a fresh one instantly and get back under the hood. The copper construction is tough and cleans up well with a pair of welpers or a reamer, but having a fresh stack on hand ensures you are never stuck trying to salvage a piece of scrap just to finish the shift. Keep your gas coverage consistent and your arc smooth with genuine Lincoln parts.
