19918 - ESAB PT-17A Replacement Plasma Electrode - Pack of 2

Keep Your PT-17A Torch Cutting

When you are in the middle of a fabrication job, the last thing you need is a plasma cutter that won't start or a cut that looks like it was gnawed off. The electrode is the heart of your plasma torch, and for owners of the ESAB PT-17 or PT-17A, the 19918 Electrode is the part you need to keep the sparks flying. This pack contains two replacement electrodes, giving you the backup you need to power through long shifts without scrambling for parts. Designed to fit perfectly into your existing torch setup, these electrodes restore the electrical connection and arc stability that are lost as old consumables wear out.

Plasma cutting generates intense heat, and the electrode takes the brunt of it. Over time, the hafnium center of the electrode pits and erodes. If you push it too far, the arc turns green—a sign you are burning copper—and you risk ruining your nozzle, swirl ring, and even the torch head. Replacing your electrode regularly is the cheapest insurance policy for your plasma cutter. These 19918 electrodes are built with durable copper and high-quality inserts to resist wear, giving you more arc-on time and fewer interruptions. They are designed to handle the amperage requirements of the PT-17A, ensuring you get the penetration and cut speed the machine was built to deliver.

Installation is straightforward and requires no special tools beyond your standard torch maintenance kit. Simply unscrew the retaining cap and nozzle, remove the old electrode, and thread the new 19918 unit into place. The precision threading ensures a snug fit for good electrical contact, which is crucial for a consistent pilot arc and main arc transfer. Whether you are working on automotive repair, HVAC ductwork, or general metal art, having a fresh electrode ensures your cuts are clean, reducing the need for grinding and secondary cleanup.

Don't let worn consumables compromise your work quality. A fresh electrode means a tighter arc, less slag, and a straighter cut. By purchasing this 2-pack, you ensure that you are ready for the next job. Compatible with the trusted ESAB PT-17A torch, these electrodes are a staple for any welder's toolbox. Keep your equipment running smooth and your cuts sharp with these essential replacement parts.
