KP2842-1 - Lincoln Electric Tomahawk LC25/LC30 Plasma Electrode (5-Pack)

Reliable Performance for Tomahawk Plasma Systems

The Lincoln Electric KP2842-1 Plasma Electrode is a critical consumable component designed specifically for the Tomahawk 375 Air and Tomahawk 30 Air plasma cutting systems. Engineered to meet the rigorous standards of Lincoln Electric, this electrode ensures that your equipment operates at peak efficiency, delivering precise and clean cuts across a variety of conductive metals. As the point of arc initiation and maintenance, the quality of the electrode directly influences the stability of the plasma stream and the quality of the finished edge.

These electrodes are compatible with the LC25 and LC30 series plasma torches, which are standard on the Tomahawk 375 and 30 Air units. Operating at a rated amperage of 25 Amps, the KP2842-1 is optimized for the thermal dynamics of these specific torches, ensuring proper cooling and hafnium insert longevity. Using genuine OEM parts like the KP2842-1 protects your torch head from damage caused by poor fitment or inferior materials often found in generic alternatives. This pack contains five electrodes, providing a necessary stock for continuous operation in industrial and fabrication environments.

Material Versatility and Application

Whether you are working with mild steel, stainless steel, aluminum, brass, or copper, the KP2842-1 electrode provides the consistent electrical conductivity required for smooth severing and gouging. In professional fabrication settings, maintaining a sharp and un-pitted electrode is essential for minimizing dross and reducing the need for secondary grinding or finishing. The hafnium emitter within the electrode is designed to withstand the high thermal loads of plasma creation, but regular inspection and replacement are necessary to prevent torch failure.

Installation and Maintenance

Replacing the electrode is a standard maintenance procedure for the LC25/LC30 torches. It is recommended to inspect the electrode during every consumable change-out. If the center pit depth exceeds the manufacturer's specifications (typically around 1/16 inch), the electrode should be discarded and replaced immediately. Failure to replace a worn electrode can lead to the arc blowing out the side of the nozzle, potentially destroying the torch head. This 5-pack ensures that operators always have a fresh replacement available, minimizing downtime and maintaining the high safety standards expected in professional workshops.
