Need Help Choosing the Right Setup?
Choosing the right equipment depends on your application, material, and welding conditions.
- For more control and precision → use smaller components and tighter setups
- For more coverage and larger welds → use larger setups and higher gas flow
- For high-heat applications (like aluminum) → use materials designed to handle increased temperatures
- For tight spaces → use more compact profiles
If you’re unsure what you need, start with a complete setup or kit and build from there.

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
- EDGE universal GL adapter with O-rings (fits both torch systems)
- 2 Series gas lens + collet (for WP-9, WP-20, WP-25)
- 4 Series stubby gas lens + collet (for WP-17, WP-18, WP-26)
- Teflon thermal spacers (used with 9/20/25 torch only)
All components matched to your selected tungsten size.
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
Optional Add-On
Pair this kit with additional tungsten, filler rod, and consumables to complete your setup for any alloy or application.
