18866 - Esab PT-31 30A Plasma Cutting Tip (5-Pack)

Reliable Cutting Performance with Esab 18866 Tips

For welders and fabricators relying on the PT-31 plasma torch, the Esab 18866 Cutting Tip (30A) is your go-to consumable for consistent, clean cuts. Whether you are working on auto body repairs, HVAC ductwork, or general light fabrication, the quality of your nozzle directly impacts the quality of your work. A worn-out tip can lead to sloppy cuts, excessive dross (slag), and frustration. This pack of five 30-amp tips ensures that you always have a fresh replacement ready, keeping your downtime to a minimum and your cut quality high.

The nozzle is the business end of your plasma cutter. It focuses the plasma arc into a tight, hot stream that melts through metal like butter. The Esab 18866 is built to handle 30 amps of power, making it perfect for cutting sheet metal and thinner plates with precision. Because it is made from durable copper, it resists the extreme heat of the arc, lasting longer than cheaper, generic alternatives. When you use genuine Esab parts, you aren't just buying a piece of copper; you are buying the assurance that your torch will fire correctly and cut straight every time you pull the trigger.

Knowing when to change your tip is key to getting the best results. If you notice your cut is starting to bevel (cut at an angle), or if the green flame of the arc starts to change color (indicating the copper is burning), it's time to swap it out. With this 5-pack, you don't have to try and squeeze "one last cut" out of a bad tip. You can simply unscrew the retaining cap, drop in a new 18866 nozzle, and get back to work in seconds. A fresh tip means a tighter arc, a narrower kerf, and less time spent grinding off dross later.

These tips are designed to fit the PT-31 torch perfectly. There is no guessing if it will seat correctly or if the gas flow will be right. They are plug-and-play for any machine equipped with this standard torch style. Keep a pack in your toolbox or on your welding cart. It’s one of those small investments that pays off big by keeping your projects moving smoothly and your finished edges looking professional. Don't let a $5 part ruin a $500 job—stick with Esab 18866 tips.
