Tweco RG-440 Rotary Ground Device 440A

Stop Fighting Twisted Cables with the Tweco RG-440

Are you tired of pausing your weld to untangle a knotted ground lead? When welding pipes, tanks, or any rotating assembly, a static ground clamp just doesn't cut it. Enter the Tweco RG-440 Roto-Ground Clamp, the industry standard for rotary grounding solutions. Designed to keep your operation running smoothly, this device allows your welding current to flow uninterrupted while your workpiece spins freely. It is the perfect companion for welding positioners, lathes, and pipe rollers.

The RG-440 is a powerhouse, boasting a 440 Amp capacity that covers the vast majority of fabrication needs. Whether you are running high-deposition flux-cored wire or precision TIG on stainless steel pipe, this rotary ground ensures that your arc starts crisp and stays stable. The secret lies in its superior copper alloy construction and precision-engineered contact surfaces, which maximize conductivity and minimize heat buildup. Unlike makeshift grounding solutions that can spark or lose contact during rotation, the Tweco Roto-Ground delivers reliable performance turn after turn.

Using the RG-440 also extends the life of your welding cables. Twisted cables aren't just annoying; they are a safety hazard and a maintenance cost. Constant twisting breaks internal copper strands, increasing resistance and causing the cable to run hot. By decoupling the cable from the rotation of the work, the RG-440 protects your equipment investment. It is a simple, effective upgrade that pays for itself by reducing downtime and equipment wear.

Tweco has been a leader in welding accessories for decades, known for quality and innovation. The RG-440 (Part No. 9250-1144) continues this tradition, offering a rugged, reliable solution for professional welders. Don't let a bad ground ruin your weld or your day—equip your shop with the Tweco Roto-Ground and experience the difference that proper grounding makes in rotary applications.
