The Tru-Weld TW6900 is a powerful stud welding system. With its 3000-Amp power source, it creates solidly fused connections quickly.
The TW6900 supports a stud range of ¼-inch to 1 ¼-inch, making it a versatile machine well-suited for various challenging applications. Whether operating in a workshop or welding in the field, even from a cargo van, this 3-phase, 60Hz system is built to handle heavy-duty jobs without struggle.
However, the machine is not compact, measuring 36 x 29 x 28 inches and weighing 760 lbs. This substantial build reflects its ability to tackle demanding applications requiring industrial-grade power.
A Stud Above the Rest
Stud welding involves directly fusing sturdy pins to substantial base metal segments, instantly forming a seamless joint. These “studs” are as strong as—or even stronger than—the thick steel plates being fastened.
The Tru-Weld TW6900 builds on this principle, incorporating advanced technology into the traditional combination of pressure and arc-welding fusion power. Here are six factors that highlight how this equipment enhances the stud welding process:
- Power output: The TW6900 delivers improved arc-generating power, surpassing the capabilities of many comparable machines, even for 1 ¼-inch studs.
- Electronic versatility: Digitally controlled accuracy eliminates guesswork. Factory presets and input for stud diameter and base metal type ensure consistent, high-quality welds.
- Building upon the electronic interface: An intuitive front-panel menu provides precise control over settings like weld time and current, offering ease of operation not typically found in heavyweight machines.
- The welding gun: The gun, which endures intense arc energy, benefits from the Pro-Tech’d feature, a circuit-protecting technology that minimizes wear and tear by isolating gun circuitry as needed.
- Duty cycle flexibility: The machine can weld ¼-inch studs continuously and handles 1-inch studs at 12–14 welds per minute, or 1 ¼-inch studs at 4–5 welds per minute. Refer to the manual for detailed cycle tables to optimize performance.
- Workflow optimization extras: From rugged wheels for portability to finely tuned material settings, the TW6900 simplifies every aspect of stud welding, ensuring reliable performance under tough conditions.
The machine excels across diverse applications, from oil rigs and bridges to large civil engineering projects. Its intuitive adjustment features—such as one-handed stud welding settings, factory presets, and custom programs—are designed for professionals who need to focus on the job rather than manual configurations.
Showcasing the Game-changing Tipping Point
The TW6900’s innovations lie in its engineering layers. At its core, a 3000-amp arc welding engine is paired with proprietary digital controls that interface with the user panel, provide gun protection, and enable precise welding management.
The system also includes the TWE17000 heavy-duty stud welding gun and an adjustable power supply. For power configuration, the machine’s top cover can be removed to access jumpers on the terminal block, allowing customization for different input voltages. Standard 230V input is supported, alongside 460V and 575V options.
Important Safety Note: Always disconnect the machine from its power supply before removing the cover. After configuration, reinstall the cover, ensure a line circuit breaker is present, and run the machine through its self-diagnostic startup routine.
The included stud gun is professionally calibrated to accommodate a variety of stud shapes and diameters. During operation, the gun compresses its main spring, lifts the stud, draws an arc to melt the tip, and completes the fusing process.
While the underlying mechanics are complex, the TW6900 simplifies operation with semi-automated menus and digital settings, empowering welders to achieve high-quality results with minimal effort.
Why the TW6900 Makes a Difference
The Tru-Weld TW6900 is built for industries with demanding requirements, including shipbuilding, aviation, bridge construction, and large-scale civil engineering. Its combination of innovative technology and robust design ensures superior stud-welded integrity and strength.
For welders of all skill levels, fatigue and job conditions can impact consistency. The TW6900 addresses these challenges with advanced electronic controls, which handle complex configurations and leave the operator free to focus on quality and efficiency. By setting new standards for reliability and ease of use, the TW6900 represents a significant leap forward in stud welding technology.
