OVERVIEW

Keep Your HW-8 Running with the ESAB 79Z97 Button Cap

If you are running a classic HW-8 TIG torch, you know there is nothing quite like the feel of that handle. But even the best torches need maintenance, and losing or breaking your back cap can bring your work to a grinding halt. The ESAB 79Z97 Button is the exact replacement part you need to get back under the hood. This isn't just a piece of plastic; it's the "shorty" cap that saves the day when you are welding in a tight corner, inside a pipe, or around a complex manifold where a standard long tail just won't fit.

We know that for professional welders, equipment reliability is everything. Using a genuine ESAB button ensures that your tungsten stays locked in tight and your shielding gas flows exactly where it should—over the puddle, not leaking out the back of the torch. This button cap is built tough to handle the heat of high-amperage TIG work without melting or cross-threading, problems often seen with cheap aftermarket knock-offs. It screws on smooth and seals up tight, giving you the confidence that your torch is ready to perform.

This part is essential for anyone keeping a "Heliarc" style HW-8 in their toolbox. Often, these older torches are the workhorses of the shop, and keeping them operational requires the right parts. The 79Z97 allows you to use short stubs of tungsten, minimizing waste and maximizing access. Whether you are a pipe welder, a fabricator, or a restoration expert, having a spare button cap in your kit is a smart move. Don't let a missing cap bench your favorite torch; grab the ESAB 79Z97 and keep laying down those dimes.

No, the HW-8 has a unique thread pattern and design. This button will not fit standard WP-series torches.

It is made from a durable, heat-resistant phenolic or composite material designed to insulate the torch head electrically and thermally.

It is called a button due to its flat, low-profile shape that resembles a button, as opposed to the pencil-like shape of standard back caps.

Typically, the button seals via mechanical fit or includes a seal depending on the specific vintage, but users should check if a separate O-ring is required for their specific torch body condition.
