KP2842-4 - Lincoln Electric KP2842-4 Tomahawk LC25/LC40 Swirl Ring (3-Pack)

Optimized Plasma Gas Dynamics

The Lincoln Electric KP2842-4 Swirl Ring is a precision-engineered consumable designed to regulate the gas flow within LC25, LC30, and LC40 plasma torches. By creating a controlled vortex of plasma gas around the electrode, this component ensures the arc remains constricted and stable, which is essential for achieving clean, high-quality cuts on materials such as mild steel, stainless steel, and aluminum. Proper gas swirling also aids in cooling the electrode, thereby extending the service life of the entire consumable stack.

This swirl ring is a direct replacement for the original equipment found in Lincoln Electric Tomahawk series plasma cutters, including the Tomahawk 375 AIR, 30 AIR, 625, and 45 models. Over time, swirl rings can become clogged with debris or suffer from heat degradation, leading to erratic arcs and poor cut angularity. Replacing the swirl ring at regular intervals is a critical maintenance step for professional fabricators requiring consistent performance.

Supplied in a package of three, the KP2842-4 ensures that operators have immediate access to spare parts, reducing potential downtime in industrial environments. Whether used in automotive repair, HVAC fabrication, or general construction, these genuine Lincoln Electric parts maintain the factory-specified tolerances necessary for optimal plasma cutting efficiency.
