Lincoln Electric KP23-50 Mig Welder Nozzle Air Cooled

Product Description

The LINCOLN ELECTRIC KP23-50 is a fixed recessed MIG welder nozzle rated for 300 to 400 amps and designed for air-cooled MIG welding guns. It directs shielding gas flow around the weld puddle to protect the arc from atmospheric contamination. The recessed design positions the contact tip setback inside the nozzle bore, which suits spray transfer and high-deposition applications where spatter buildup is a concern. With a 0.5-inch bore diameter, this nozzle is sized for moderate to high-amperage semi-automatic MIG welding processes. Licensed welders and fabrication professionals install this as a consumable replacement part during routine gun maintenance.

This nozzle is suited for semi-automatic MIG welding in fabrication shops, manufacturing facilities, and maintenance welding environments. The air-cooled design makes it appropriate for duty cycles and amperage ranges where water-cooled guns are not required. It is intended for use with Lincoln Electric welding guns and is a direct consumable replacement installed during gun servicing or when spatter accumulation degrades shielding gas coverage and weld quality.

Key Features

• Fixed recessed nozzle design reduces spatter accumulation inside the bore during high-amperage welding
• Rated for 300 to 400 amps, suitable for moderate to high-deposition MIG processes
• Air-cooled construction for standard semi-automatic MIG gun applications
• 0.5-inch bore diameter optimized for shielding gas coverage at elevated amperage
• Direct consumable replacement for Lincoln Electric MIG gun maintenance

Compatibility

Designed for use with Lincoln Electric MIG welding guns as stated by the manufacturer. Confirm gun model compatibility with Lincoln Electric documentation before installation.

Installation Notes

This nozzle is installed and replaced by qualified welders or welding equipment technicians as a routine consumable. Before replacing the nozzle, power down the welding machine and allow the gun to cool completely. Thread or press the nozzle onto the gun diffuser according to the gun manufacturer's assembly instructions. Inspect the contact tip and gas diffuser for wear at the same time to ensure proper shielding gas flow after reassembly.
