92501124 - Tweco RG-240 800A Rotary Ground Clamp

Industrial Rotary Grounding Solution

The Tweco RG-240 Roto-Ground Clamp (SKU: 9250-1124) is a specialized grounding device engineered for high-amperage welding applications involving rotating workpieces. In industrial fabrication environments where pipes, tanks, or vessels are welded on turning rolls or positioners, standard ground clamps often fail to accommodate the continuous rotation. This leads to cables wrapping around the workpiece, causing insulation damage, potential arcing, and significant safety hazards. The RG-240 addresses this critical issue by providing a stationary cable connection point while the contact head rotates freely with the work.

Rated for 800 Amps, the RG-240 is built to handle heavy-duty welding cycles without overheating. Its robust internal design ensures consistent electrical conductivity across the rotating interface, preventing voltage drops that could affect weld quality. The unit is designed to accommodate 2-4/0 welding cables, providing ample current-carrying capacity for demanding structural and pipe fabrication tasks. By maintaining a solid ground connection on moving parts, the Tweco Roto-Ground protects expensive bearings in positioners from stray welding current and extends the lifespan of your welding cables.

This device is an essential component for any automated or semi-automated welding setup involving rotation. Its durable construction ensures long-term reliability in harsh shop environments, making it a standard choice for professional fabricators requiring efficiency and safety.
