Lincoln Electric KP2742-1-50S Mig Welder Gas Nozzle

Product Description

The LINCOLN ELECTRIC KP2742-1-50S is a threaded stickout-type gas nozzle designed for MIG welding applications. It features a 0.5-inch bore diameter and is constructed from metal for durability under continuous welding conditions. The nozzle threads onto compatible MIG gun consumable assemblies and directs shielding gas flow around the weld puddle to protect it from atmospheric contamination. Rated to a maximum of 350 amps, this nozzle is suited for higher-output MIG welding work and is installed by welding technicians and maintenance welders as a routine consumable replacement.

This nozzle is specified for use with the Lincoln Electric Magnum PRO MIG gun series. It fits standard threaded nozzle retention on those guns and is a direct replacement during routine consumable service intervals. The stickout-style design provides clearance for welding in tighter joint configurations where a recessed or flush nozzle would restrict visibility or access. It is appropriate for both shop and field welding environments where shielding gas coverage consistency is critical to weld quality.

Key Features

• 0.5-inch bore diameter for consistent shielding gas distribution
• Threaded connection type for secure, repeatable installation
• Stickout nozzle style for improved access to tighter weld joints
• Rated to 350 amps maximum for higher-output MIG applications
• Metal construction for heat resistance and extended service life

Compatibility

Designed for use with the Lincoln Electric Magnum PRO MIG gun series with threaded nozzle retention.

Installation Notes

This nozzle is installed and replaced by welders or maintenance technicians as part of routine MIG gun consumable service. Always power down the welder and disconnect the gun from the wire feeder before replacing nozzle consumables. Thread the nozzle on by hand until snug and verify a secure fit before resuming welding operations. Inspect the nozzle regularly for spatter buildup and replace when bore restriction affects shielding gas coverage.
