Tweco WCRG-2000 Rotary Ground Device 2000A

Essential Protection for Welding Positioners and Turning Rolls

Maximize the lifespan of your shop's automated equipment with the Tweco WCRG-2000 Roto-Work Clamp. In the world of industrial welding, efficiency is driven by automation—using positioners, manipulators, and turning rolls to rotate pipe and tanks for continuous welding. However, this rotation presents a unique problem: how to ground a moving part. Standard ground clamps cannot be used as the cables would quickly twist and snap. Furthermore, relying on the table or rollers for grounding is a recipe for disaster, as the welding current will arc across the lubricated bearings, destroying them from the inside out. The Tweco WCRG-2000 is the industry-standard solution to this problem.

This heavy-duty rotary ground clamp is rated for a massive 2000 Amps, making it the go-to choice for shops performing Sub-Arc or heavy MIG welding on thick materials. It works by attaching directly to the rotating fixture or workpiece, allowing the current to transfer smoothly through the device's internal contact mechanism to a stationary cable connection. This design ensures that your welding cables remain static and safe while your pipe or vessel spins at the required welding speed. The result is a safer shop environment, reduced cable wear, and a stable arc that isn't interrupted by poor ground connections.

The WCRG-2000 is built with the durability that professional welders expect from Tweco. The copper alloy body resists spatter adhesion and withstands the heat generated during long weld cycles. For maintenance teams, this device is an investment in preventative care; the cost of a Roto-Work clamp is a fraction of the cost of replacing precision bearings on a heavy-duty positioner. It is an indispensable accessory for any fabrication facility dealing with circumferential welds on a daily basis. Ensure your shop runs smoothly and your equipment stays protected with this high-capacity grounding solution.

Applications:

• Pipe Welding: Essential for spooling shops using rotators.
• Vessel Fabrication: Handles the high amps required for thick-wall tank welding.
• Hard Automation: Provides reliable grounding for robotic cells with rotary axes.
• General Fabrication: Useful for any setup requiring continuous 360-degree welding.
