Lincoln Electric KP2742-1-50F-B25 Mig Welder Gas Nozzle

Product Description

The LINCOLN ELECTRIC KP2742-1-50F-B25 is a flush bottleneck MIG welder gas nozzle designed for use with Magnum PRO MIG guns. Constructed from metal, it features a threaded connection type and a 0.5-inch bore diameter. Rated for up to 350 amps, this nozzle channels shielding gas around the weld pool to protect the arc and finished bead from atmospheric contamination. It is a consumable replacement part installed by welding technicians and fabricators during routine maintenance or when a worn nozzle causes arc instability or excessive spatter.

This gas nozzle is suited for MIG welding applications where consistent shielding gas coverage is critical, including structural fabrication, pipe welding, and general metal fabrication in both shop and field environments. The flush bottleneck profile works well in tight joint access situations while maintaining adequate gas coverage. Its threaded connection ensures a secure, repeatable fit during nozzle changeovers on Magnum PRO MIG guns.

Key Features

• Flush bottleneck nozzle geometry for access in tighter joint configurations
• 0.5-inch bore diameter for consistent shielding gas flow coverage
• Rated to 350 amps for use in higher-amperage MIG welding processes
• Threaded connection type for secure, tool-free installation and removal
• Metal construction for durability under sustained arc heat and spatter

Compatibility

Designed for use with Magnum PRO MIG guns as specified by Lincoln Electric.

Installation Notes

This nozzle is installed and replaced by welding technicians as part of standard consumable maintenance on MIG welding equipment. Always power down and disconnect the welder from its power source before removing or installing nozzle components. Inspect the gas diffuser and contact tip for wear at the same time as the nozzle replacement. Follow the MIG gun manufacturer's service guidelines for proper torque and seating of threaded nozzle connections.
