KP24A-37-SS - Lincoln Electric KP24A-37-SS Magnum 400 Slip-On Recessed Gas Nozzle 3/8" ID

Optimize Your Magnum 400 Gun with the KP24A-37-SS Nozzle

For professional welders relying on Lincoln Electric Magnum 400 MIG guns, the KP24A-37-SS Gas Nozzle is the standard for durability and performance. This nozzle features a 3/8-inch (0.375 in) bore, which is ideal for standard wire diameters and applications requiring a tight, controlled gas cone. The narrower opening helps increase gas velocity slightly, which can be beneficial in drafty shop environments or when welding in positions where gas coverage is critical.

The standout feature of this nozzle is its recessed tip design. By keeping the contact tip recessed inside the nozzle, you gain an extra layer of protection against spatter bridging and electrical shorts. This is particularly useful when you are dragging the nozzle or working in corners where the nozzle edge might touch the base metal. Additionally, the recess allows for a longer electrical stick-out (ESO) when necessary, giving you flexibility in heat input control. The slip-on style is a favorite among welders for its convenience; simply twist and pull to remove it for cleaning or to swap out a contact tip. No seized threads to fight with at the end of a long shift.

Rated for use with 400-amp guns, this nozzle handles the heat of spray transfer and high-deposition flux-cored welding without melting or warping prematurely. Whether you are welding mild steel, stainless, or aluminum, consistent shielding gas flow is paramount, and the KP24A-37-SS delivers exactly that. Keep a few of these in your toolbox to ensure your Magnum gun is always ready to lay down high-quality beads with minimal interruption.
