92551120 - Tweco WCRG-2000 Rotary Ground Device 2000A

High-Capacity Rotary Grounding for Automated Fabrication

The Tweco WCRG-2000 Roto-Work Clamp (SKU: 9255-1120) is a premier solution for heavy-industrial welding applications involving rotating workpieces. Designed to handle an impressive 2000 Amperes, this device is engineered for the rigorous demands of pipe fabrication shops, pressure vessel manufacturing, and large-scale tank construction. In automated welding environments where workpieces are mounted on positioners or turning rolls, maintaining a consistent ground connection without twisting cables is a significant challenge. The WCRG-2000 solves this by providing a stationary connection point for the welding cable while the contact head rotates freely with the workpiece.

One of the primary technical advantages of the WCRG-2000 is its ability to protect capital equipment. Without a dedicated rotary ground, welding current often seeks the path of least resistance to the ground, which frequently passes through the bearings of the turning rolls or positioners. This passage of high-amperage current causes arcing within the bearings (a phenomenon known as electrical pitting or fluting), leading to premature equipment failure and costly downtime. By providing a direct, low-resistance path for the current, the Tweco Roto-Work clamp effectively isolates the machinery's sensitive mechanical components from electrical damage.

Constructed from high-grade copper alloy, the WCRG-2000 ensures maximum conductivity and efficient heat dissipation, which is critical when operating at currents up to 2000 amps. This makes it particularly suitable for high-deposition processes such as Submerged Arc Welding (SAW) and heavy-duty Flux-Cored Arc Welding (FCAW). The unit is designed for easy mounting and maintenance, ensuring that it can be integrated seamlessly into existing automation cells. Whether you are welding thick-wall pipe or massive structural components, the reliability of your ground connection dictates the stability of your arc; the Tweco WCRG-2000 delivers that stability consistently.

Key Features:

• 2000 Amp Rating: Supports high-energy welding processes without overheating.
• Equipment Protection: Prevents arcing damage to positioner and lathe bearings.
