92551112 - Tweco WCRG-1200 Rotary Ground Clamp 1200A

High-Performance Rotary Grounding Solution

The Tweco WCRG-1200 Roto-Work Clamp (SKU: 92551112) is a specialized industrial grounding device engineered to solve the common challenges associated with welding rotating workpieces. In heavy fabrication environments—such as pipe welding, vessel manufacturing, and automated tank seam welding—standard ground clamps often fail because the rotation of the workpiece causes the welding cable to wrap around the fixture. This twisting creates tension, damages the cable strands, and can eventually sever the connection or damage the welding machine. The WCRG-1200 addresses this by providing a highly conductive, rotating interface that allows the ground cable to remain stationary while the workpiece spins freely.

Rated for a substantial 1200 Amperes, this Roto-Ground unit is built for high-deposition and high-duty-cycle applications, including Submerged Arc Welding (SAW) and heavy-duty Flux Cored Arc Welding (FCAW). The unit features a dual-head design that distributes the current load effectively, minimizing heat buildup at the contact points. Constructed from robust copper alloys, the WCRG-1200 ensures maximum electrical conductivity and thermal dissipation. The internal mechanism is designed to maintain constant contact pressure, ensuring that the welding arc remains stable and free from the fluctuations often caused by poor grounding on moving parts.

Installation of the WCRG-1200 is straightforward, typically attaching directly to the spindle of a positioner or a dedicated fixture on the turning rolls. By integrating this rotary clamp into your welding automation setup, you significantly reduce maintenance downtime associated with untangling cables and replacing worn-out leads. It is a critical component for any fabrication shop looking to optimize the efficiency and safety of their circumferential welding operations. The device is engineered by Tweco, a leader in arc welding accessories, ensuring compliance with rigorous industrial standards for durability and performance.

Key Technical Benefits:
