Custom TIG Cups & Welding Solutions

Custom TIG Cups & Welding Solutions

Not every welding challenge can be solved with an off-the-shelf TIG cup.

EDGE Welding Supply works directly with welders, fabricators, welding engineers, manufacturers, automation specialists, and industrial customers to develop custom TIG cups and welding solutions for applications where standard products fall short.

Whether you need a custom TIG cup, an extended TIG cup, a filler wire access solution, a specialty shielding gas solution, an automation-specific design, or a completely unique modification, our goal is simple:

Help you solve the welding challenge—not just sell another product.

Many custom projects begin with challenges such as:

• Tight joint access
• Extended tungsten stick-out requirements
• Limited torch clearance
• Fixture interference
• Restricted filler wire access
• Automation and orbital welding applications
• Specialty shielding gas coverage requirements

Our custom solutions have supported customers across a wide range of industries, including aerospace, manufacturing, precision fabrication, pharmaceutical processing, food and beverage processing, semiconductor manufacturing, research and development, energy and power generation, automotive, automated welding systems, orbital welding, and prototype development.

Have a welding challenge that standard TIG cups can't solve? We'd be glad to discuss your application and determine whether a custom TIG cup or application-specific welding solution can help. Contact EDGE Welding Supply to start the conversation.

Real-World Applications

Many of our most interesting custom projects cannot be shared publicly. We regularly work with customers in industries where non-disclosure agreements (NDAs) and confidentiality requirements prevent us from sharing project details or photographs.

One example involved a customer welding deep inside a valve body. The application required a custom TIG cup that would allow the use of a full-length tungsten while maintaining excellent shielding gas coverage. The customer also wanted to ride the cup against the bottom of the valve body while keeping the tungsten slightly recessed inside the cup to reduce the risk of contaminating the tungsten in a low-visibility environment.

To accomplish this, we modified one of our Laminar Flow XX-Tended reach cups from high-temperature quartz and machined an angled opening across part of the face. This allowed the cup to be placed directly on the valve body floor while providing a clear path for the filler wire to enter through the side port in the valve body and into the weld puddle. The result was improved visibility, better control of the tungsten, and a practical solution to a welding challenge that could not be solved with a standard TIG cup.
