Q21657 - ESAB PT-25 Plasma Torch Electrode Holder Assembly

Restore Your PT-25 Torch Performance

If your ESAB or L-Tec PT-25 plasma torch is misfiring, eating up electrodes, or struggling to maintain a stable arc, the problem might not be your consumables—it could be the electrode holder. The ESAB Q21657 Electrode Holder is the direct replacement part you need to get your trusty PT-25 back in the fight. This isn't just a piece of brass; it's the anchor for your entire cutting operation, holding the electrode exactly where it needs to be for that perfect, focused plasma stream.

We know that downtime kills productivity. When the threads on your old holder get stripped or the contact surface gets pitted from thousands of starts, your cut quality suffers. Swapping in a fresh Q21657 eliminates those variables. It screws in perfectly, grips the electrode tight, and ensures the current flows smoothly without resistance heating. This means cooler running, longer consumable life, and less frustration when you pull the trigger.

Don't risk your torch head with ill-fitting aftermarket knock-offs. This genuine ESAB part is built to handle the heat and abuse of industrial environments. Whether you are fabricating in a shop or doing repair work in the field, keeping your torch internals in top shape is the secret to reliable cutting. Keep a spare Q21657 in your kit so you never get stuck with a dead torch in the middle of a job.
