TW6950 Features

The TW6950 is engineered for demanding production environments where welding consistency, output capacity, and process control are critical. Its 3000-amp platform, advanced digital controls, and production-focused functionality make it well-suited for welding larger-diameter arc weld studs in fabrication, structural steel, and industrial manufacturing applications.

3000 Amp Welding Output

The TW6950 utilizes a high-capacity 3000-amp power supply designed for demanding stud welding applications. The available output supports consistent welding performance across a broad range of stud diameters, including large fasteners up to 1".

Smooth Arc Curve Technology

The system features a controlled arc characteristic that helps maintain welding stability throughout the weld cycle. This smooth arc profile supports a wider welding range and contributes to improved weld consistency across varying stud sizes.

PRO-TECH'D Arc Stud Welding Gun

PRO-TECH'D technology is built into the TWE17000 stud arc welding gun circuit. In sustained production arc stud welding environments running large-diameter studs at the duty-cycle limits, gun circuit failures are the most common maintenance cost. This protection extends the service life of the welding gun and reduces repair frequency on the machine's most-used consumable component.

Stepless Time and Current Adjustment

Digital weld controls provide stepless adjustment of both welding time and welding current. This allows operators to fine-tune welding parameters with precision rather than relying on fixed incremental settings.

Enhanced Production Duty Cycle

Built for manufacturing environments, the TW6950 offers high-duty-cycle performance for repetitive welding operations. The system is designed to support continuous production schedules while maintaining stable welding output.

Safety Welding Interlock System

An integrated welding interlock prevents accidental double triggering during operation. This feature helps protect consumables, reduces unnecessary chuck wear, and contributes to more controlled welding cycles.
