KP23-50 - Lincoln Electric KP23-50 Fixed Recess Gas Nozzle, 1/2-Inch Bore for Magnum Guns

Reliable Performance for Your Daily Welding Tasks

When you are under the hood, the last thing you want to worry about is your gas coverage. The Lincoln Electric KP23-50 Gas Nozzle is the workhorse nozzle for welders using the popular Magnum 250L, 300, or 400A MIG guns. Whether you are in a production line, a job shop, or working on a project in your garage, this 1/2-inch nozzle provides the perfect balance of gas flow and accessibility. The 1/2-inch bore is the "goldilocks" size—large enough to provide a wide umbrella of shielding gas to protect your weld pool from porosity, but narrow enough to get into corners and fillet welds without getting hung up.

The standout feature for many welders is the fixed recess. If you have ever struggled with a slip-on nozzle sliding around or accidentally touching your contact tip to the work, you will appreciate the stability of this design. The fixed recess keeps your contact tip tucked safely inside the nozzle. This does two things: it helps prevent the tip from shorting out if you drag the cup, and it keeps the tip cleaner by shielding it from the immediate splash of the weld puddle. This means fewer interruptions to change tips and more time laying beads.

Built tough to handle the heat, this copper nozzle stands up to the abuse of daily welding. It resists spatter buildup, and what little spatter does stick can usually be easily cleaned out with standard MIG pliers or a quick dip in nozzle gel. It is designed to slide securely onto your gun's insulator, giving you a tight seal that prevents air from being sucked into your shield gas stream. If you are welding mild steel, stainless, or flux-core applications requiring gas, the KP23-50 is the reliable, standard replacement part that restores your gun's performance to factory specs.

Don't let a worn-out or clogged nozzle ruin your weld quality. Keeping a fresh pack of KP23-50 nozzles in your toolbox ensures you are always ready to tackle the next joint with confidence, knowing your gas coverage is consistent and your equipment is protected.
