TW6900 Features

The TW6900 boasts a sleek design and advanced technology to enhance the user experience. Key features include a high-resolution display and robust performance capabilities that cater to diverse needs.

3,000 Amp Welding Power

The TW6900 delivers up to 3,000 amps of welding output, providing the power required for large-diameter arc weld studs and heavy-duty fastening applications. Its high-current design supports demanding structural and industrial welding operations.

Welds Studs Up to 1-1/4"

Engineered for maximum stud welding capacity, the system is designed to weld studs up to 1-1/4" diameter. This capability makes the TW6900 suitable for large structural components, heavy equipment fabrication, and infrastructure projects.

Digital Weld Parameter Controls

Integrated digital controls allow operators to accurately adjust weld current, weld time, and gas purge settings. Precise parameter management helps improve consistency and repeatability throughout the welding process.

Factory and User-Programmable Presets

The system includes factory welding presets along with user-programmable memory settings. Operators can quickly store and recall preferred welding parameters for recurring production jobs and material configurations.

Enhanced Weld Control Technology

The updated weld control platform improves arc stability and process consistency. This enhanced control helps maintain uniform weld quality across a broad range of stud diameters and production conditions.

Pro-Tech'd Circuit Protection

Pro-Tech'D technology helps protect the welding gun circuitry and critical internal electrical components from operational faults and electrical surges. This protection contributes to improved equipment reliability and reduced maintenance concerns.

Built for Heavy-Duty Stud Welding Applications

When production demands involve larger studs, higher welding output, and consistent process control, equipment selection becomes increasingly important. Complete Stud Welding can help evaluate your application requirements and determine whether the TW6900 is the right fit for your operation.
