KP22-37 - Lincoln Electric KP22-37 Magnum Gas Nozzle 0.37 ID

Reliable Nozzle for Tight Spots and High Heat

When you are in the middle of a heavy welding job, the last thing you need is a nozzle that can't take the heat or won't fit where you need it to go. The Lincoln Electric KP22-37 Gas Nozzle is built for welders who demand toughness and versatility from their Magnum MIG guns. With a 0.37-inch inner diameter, this nozzle is your go-to solution for reaching into corners, tight V-grooves, or complex assemblies where a standard 1/2-inch or 5/8-inch nozzle just feels too bulky. It gives you the clearance you need to see the puddle and keep the arc right where it belongs without sacrificing gas coverage.

Don't let the smaller size fool you; this nozzle is a workhorse. It is rated to handle the heat of 300 A and even 400 A welding applications. This means you can run hotter settings for thicker materials without worrying about the nozzle melting down or deforming prematurely. It is designed to fit the popular Magnum 200 Series guns, making it a standard replacement part for many shop floors. The slip-on design is a favorite among operators because it makes swapping out nozzles fast and easy—no threads to seize up with spatter, just pull it off, clean it, or slap on a new one and get back to burning wire.

The KP22-37 also features a fixed recess design. For the welder, this means one less thing to worry about adjusting. The nozzle seats in the same spot every time, keeping your contact tip recessed at the correct depth for optimal shielding. This helps prevent the tip from shorting out against the work and ensures your shielding gas forms a proper envelope around the weld, keeping the air out and the porosity away. It’s a simple, effective design that helps you maintain a consistent stick-out.

Whether you are fabricating structural steel, repairing heavy equipment, or doing general production work, having the right consumables on your gun makes a difference. The Lincoln KP22-37 offers the perfect balance of access and durability. Keep a few in your toolbox so you are always ready for those tight joints or high-amperage runs. It’s genuine Lincoln quality that fits your Magnum gun perfectly, helping you lay down smooth, clean beads shift after shift.
