Why We Started Rethinking TIG Shielding and Cup Design

We didn’t start as a welding company.

Our background was in scientific glassblowing and manufacturing precision glass products for scientific and industrial applications. In that environment, you learn quickly that tooling matters, tolerances matter, and small design changes can completely change the outcome of a process.

You also learn that if the right tool doesn’t exist, sometimes you have to build it yourself.

That mindset eventually carried over into TIG welding.

Although we were not certified welders, welding was always around us growing up. Before stepping into the world of scientific glassblowing, we lived in a farming community. Being involved with mechanics, hot rods, engines, fabrication, and shop environments gave us an understanding of how important tools and process improvements can be.

When we first entered the TIG welding industry, we noticed most available glass or diffuser-style cups were limited to only a few large diameter sizes. Smaller cups were often treated as basic consumables with little attention given to gas flow behavior or shielding stability.

We started with five basic cup sizes — #4, #5, #6, #7, and #8 — with the original goal of improving visibility and giving welders more flexibility through glass cup designs and customization.

As we spent more time around TIG welding applications, we kept noticing the same problem repeatedly: shielding gas behavior was inconsistent across both small and large cup setups.

At the time, most diffuser-style systems were focused primarily on larger diameter cups. We believed smaller cups could also benefit from improved gas stability and more controlled shielding coverage.

That pushed us toward developing our own diffuser systems and experimenting with ways to improve laminar flow characteristics across multiple cup sizes and geometries.

A lot of our early development came directly from customer applications.

One customer needed a custom cup long enough to weld deep inside a pocket for a satellite component with almost no room for error. Another customer needed to weld deep inside a valve body while maintaining wire access and visibility in an extremely confined area. We designed a high-temperature quartz cup with a chamfered edge that allowed wire access while also protecting the tungsten from accidental contact due to limited visibility.

As more difficult applications came in, the designs continued evolving.

Orbital welding applications pushed us toward increasingly compact cup geometries that still needed stable shielding coverage. Narrow groove welding created additional challenges involving cameras, visibility, and restricted-access applications. Automated welding applications introduced completely different geometry challenges.

Over time, these applications led to the development of our laminar flow cup series, indexing systems, narrow-profile cups, rectangular cups, and other application-specific shielding solutions.

One of the things we discovered during development was how much tungsten extension could be increased once shielding gas became more stable.

Traditional TIG setups usually limit tungsten stickout because shielding coverage becomes increasingly unstable as the electrode moves farther away from the cup. As turbulence increases, atmospheric contamination becomes more likely as oxygen is pulled into the shielding gas and deposited into the weld area, especially in restricted-access environments.

As we refined our diffuser systems and cup geometries, customers began pushing tungsten extension much farther than conventional recommendations would normally allow.

In one turbine repair application, customers rebuilding power generation equipment needed to weld deep between turbine fins where torch access was extremely limited. Conventional setups simply did not provide enough reach while maintaining reliable shielding coverage.

By improving gas stability and maintaining a more controlled shielding envelope, they were able to run several inches of tungsten extension while still maintaining weld protection in extremely confined areas.

Even smaller cup sizes allowed more tungsten extension than most welders would normally expect. In many cases, the visible laminar flow extended well beyond the tungsten itself.

Those applications reinforced something we had been observing from the beginning:

gas coverage and shielding stability play a major role in solving many of the problems welders experience.

Today, our focus continues to be centered around solving difficult shielding and weld-access problems for industries where consistency matters. Aerospace, orbital welding, nuclear, robotics, turbine repair, sanitary, and other high-precision applications often require solutions that simply do not exist as standard off-the-shelf products.

Our approach has remained the same from the beginning:

listen to the customer, understand the problem, and build solutions around the application instead of forcing the application around the product.

For us, it has never really been about simply making TIG cups.

It has always been about improving shielding stability, gas coverage, weld access, and process reliability in situations where the weld is too important to fail.
