The EDGE Cornerstone Welding Cup Bundle – Focused Performance for Every Fabricator and Welder
The Cornerstone is a complete, professional-quality TIG glass cup bundle built for fabricators and welders who want a focused, high-performance setup. With a purpose-built cup selection matched to your tungsten size, it's the kit that covers what most shops actually need — without piecing parts together or swapping cups between jobs.
Key Benefits
- Complete Professional Setup – Everything you need in one kit, matched to your tungsten size
- Dual Torch Compatibility – Works with 9/20/25 and 17/18/26 series torches
- Two Purpose-Built Cup Profiles – Each cup chosen for a specific material and position
- Better Gas Coverage – EDGE laminar-flow diffuser for cleaner, more consistent shielding
- Teflon Thermal Spacers Included – Reduces heat transfer to the torch body for longer consumable life
- Versatile Applications – Aluminum, stainless, chromoly, titanium, and more
What's Included
- Clear storage case
- 2 EDGE glass cups:
- #8LF Pyrex – Versatile size for general welding applications with laminar flow for consistent shielding
- #12S Pyrex – Balanced coverage for controlled welding environments and confined joints

Why This Kit Works
Most fabricators weld more than one material. The Cornerstone is designed around that reality. Each cup has a job: the #8LF handles versatile general applications with superior gas coverage, and the #12S delivers balanced coverage when smaller cups aren't quite enough. Professional-quality components, ready to run right out of the case.
EDGE Advantage
- Laminar gas flow for more consistent shielding
- Clear visibility of the weld puddle
- Precision-machined components
- Designed for real-world welding conditions
