9-4798 - Thermal Dynamics 15ft Work Lead Ground Clamp Assembly

Genuine Thermal Dynamics 9-4798 Negative Work Lead

Ensure your plasma cutting operations run smoothly with the Thermal Dynamics 9-4798 Negative Lead. This 15-foot (4.6-meter) work cable is a genuine OEM replacement part designed specifically for Thermal Dynamics plasma cutting systems. A compromised ground connection is a common cause of poor cut quality, pilot arc failure, and intermittent arc stability. Replacing a worn or damaged work lead restores the electrical integrity of your machine, ensuring consistent performance.

The assembly features a robust, heavy-duty ground clamp designed to grip securely onto workpieces, plates, or welding tables. The strong spring mechanism ensures low-resistance contact, which is vital for the high-amperage circuits used in plasma cutting. The cable itself is insulated with durable, industrial-grade rubber that withstands the rigors of the shop floor, including exposure to sparks, abrasion, and oil.

This lead is compatible with various models in the Cutmaster series and other Thermal Dynamics power sources requiring a standard plug connection. Whether you are replacing a lost cable or upgrading a damaged one, this 15-foot lead provides the reach and reliability professional fabricators demand.
