OVERVIEW

Lincoln Electric Magnum PRO 350A Slip-On Nozzle – KP2742-2-50R

Upgrade your MIG welding gun with the genuine Lincoln Electric KP2742-2-50R Slip-On Nozzle, a staple component for the Magnum PRO 350A welding gun platform. This nozzle is crafted to deliver consistent shielding gas coverage and superior durability in demanding welding environments. Featuring a 1/2-inch bore, it provides excellent gas flow for standard wire sizes, ensuring a clean, contaminant-free weld pool. The 1/8-inch recessed tip configuration is particularly beneficial for protecting the contact tip from radiant heat and spatter, extending the life of your contact tips and reducing the frequency of replacements.

The KP2742-2-50R is built with efficiency in mind. Its slip-on design eliminates the frustration of seized threads, allowing welders to remove and replace the nozzle in seconds—even when the gun is hot. A built-in internal insulator ensures the nozzle remains electrically isolated from the contact tip, preventing accidental arcing to the workpiece. The exterior is finished with a high-quality nickel plating, which acts as a barrier against spatter. Spatter that does land on the nozzle can be easily brushed or tapped off, keeping your workflow uninterrupted.

Designed for 350A applications, this nozzle is robust enough for structural steel work yet precise enough for lighter fabrication tasks. It integrates perfectly with the Magnum PRO system's gas diffusers and insulators, creating a tight seal that prevents gas leakage and atmospheric contamination. When you choose genuine Lincoln Electric parts, you are investing in the reliability and performance that professional welders trust. Keep your arc stable and your welds clean with this essential Magnum PRO consumable.

Features & Benefits:

  • Spatter Resistant: Nickel plating prevents spatter from sticking, making cleaning easy.
  • Cool Operation: Designed to dissipate heat effectively, protecting the gun's front end.
  • Quick Change: Slip-on friction fit allows for tool-free replacement.
  • Optimal Coverage: 1/2" ID is versatile for a wide range of joint configurations.
