Replacement Plasma Electrode for Lincoln Pro-Cut 55/80 (KP2063-1B1)

Keep Your Pro-Cut Cutting Clean

Don't let a worn-out electrode slow down your production or ruin a perfectly good piece of metal. The P4391 Replacement Plasma Electrode is the smart choice for operators of Lincoln Electric Pro-Cut 55 and Pro-Cut 80 plasma cutters. Designed to replace the KP2063-1B1, this electrode delivers the performance you expect at a price that keeps your shop profitable. Whether you are cutting mild steel, stainless, or aluminum, a fresh electrode is the first step to a smooth, clean edge.

Plasma electrodes are the workhorses of your torch. Over time, the center insert wears down, leading to a wandering arc, excessive dross, and eventually, a green flame that indicates you are burning copper—a sure sign that you've waited too long to swap parts. By keeping a supply of P4391 electrodes on hand, you ensure that your machine is always ready to perform. These electrodes are built to withstand the heat and current of 55-80 amp cutting, providing reliable starts and consistent arc quality.

Installation is quick and easy, fitting perfectly into your existing Pro-Cut torch setup. Simply unscrew the old electrode and thread in the new P4391, ensuring it is snug but not overtightened. Pair this with a fresh nozzle for the best results. Ideal for automotive shops, farm repair, and general fabrication, this replacement part helps you get the most out of your older Lincoln plasma machine without breaking the bank on consumables.
