92501164 - Tweco RG-640 600A Rotary Ground Device

High-Performance Grounding for Automated Welding

The Tweco Roto-Ground Clamp RG640 (SKU: 9250-1164) is an essential component for industrial welding operations involving rotating workpieces. Designed to handle high amperage applications, this device provides a reliable 600 Amp grounding solution that integrates seamlessly with turning rolls, positioners, and pipe welding stations. In automated or semi-automated environments, maintaining a continuous and stable electrical ground is critical for weld quality. The RG-640 ensures that current flows efficiently from the rotating part to the power source without interruption.

Eliminate Cable Twisting

One of the primary challenges in welding pipes, tanks, or vessels on a rotator is the management of ground cables. Static clamps will cause cables to wrap around the workpiece, leading to tension, cable damage, and potential safety hazards. The Tweco Roto-Ground solves this by allowing the grounding head to rotate freely with the workpiece while the cable connections remain stationary. This design not only protects your expensive welding cables but also prevents the erratic arc characteristics caused by fluctuating ground contact.

Heavy-Duty Construction

Built to withstand the rigors of heavy fabrication shops, the RG-640 features a robust copper alloy construction that maximizes electrical conductivity and dissipates heat effectively. The unit is designed with dual cable connection points, allowing for the use of multiple cables to handle the full 600 Amp load without overheating. Its internal mechanism is engineered for long service life, requiring only standard maintenance to keep the conductive surfaces functioning smoothly. For fabrication shops focused on pipe spools, pressure vessels, or large cylindrical structures, the Tweco RG-640 is the industry standard for rotary grounding.
