OVERVIEW

Reliable Shielding for Heavy-Duty MIG Welding

The Lincoln Electric KP23H-62 Gas Nozzle is a premium consumable designed to maintain the performance and longevity of your Magnum® series MIG guns. Engineered specifically for the Magnum 300 and Magnum 400 (including 400A) gun models, this nozzle features a robust heavy-duty construction. The increased wall thickness allows it to withstand the intense radiant heat generated during high-amperage welding procedures, reducing the frequency of replacements and ensuring consistent operation during long weld cycles.

With an inner diameter (ID) of 0.62 inches (approximately 15.7 mm or 5/8 inch), this nozzle provides a standard orifice size suitable for a wide variety of welding applications. The 5/8-inch bore strikes an excellent balance between gas coverage and joint accessibility, making it a versatile choice for general fabrication, structural steel, and heavy equipment repair. It effectively directs the shielding gas over the weld pool, protecting it from atmospheric contamination and porosity, which is critical for achieving X-ray quality welds.

The KP23H-62 utilizes a threaded recess design. This configuration serves two main purposes: it ensures a tight, leak-proof mechanical connection to the gun tube, and it positions the contact tip in a recessed location relative to the nozzle exit. A recessed tip is particularly advantageous for short-circuit MIG welding and higher current spray transfer modes, as it helps protect the contact tip from excessive spatter and radiant heat while maintaining proper electrical stick-out. This nozzle is compatible with wire diameters ranging from .025 inches up to 5/64 inches, offering flexibility across different welding procedures.

Genuine Lincoln Electric consumables are manufactured to precise tolerances to ensure seamless compatibility with your equipment. Using the correct nozzle not only improves gas flow characteristics but also helps prevent electrical shorts and arc instability caused by poor fitment. Whether you are welding mild steel, stainless, or other alloys, the KP23H-62 delivers the durability and precision required for professional industrial environments.

FAQ

The KP23H-62 is designed for use with Lincoln Electric Magnum® 300 and Magnum® 400 (including 400A) series MIG guns.

This nozzle has an inner diameter (ID) of 0.62 inches, which is equivalent to 5/8 of an inch or approximately 15.7 mm.

The KP23H-62 is a threaded nozzle, which ensures a secure connection to the gun and prevents gas leakage.

This nozzle is rated for use with MIG wire sizes ranging from .025 inches up to 5/64 inches.

Recess refers to the position of the contact tip relative to the nozzle opening. In this nozzle, the contact tip sits back inside the nozzle, which helps protect the tip from spatter and heat.

Yes, the KP23H-62 is a Fixed Heavy Duty nozzle, featuring thicker walls for better heat resistance and durability in high-amperage applications.
