The C Clamp Ground Clamp is a heavy-duty grounding device rated for capacities up to 600 amps, designed for high-amperage welding applications. Its C-type configuration enables secure attachment to flat or round conductors, providing reliable performance in industrial environments where consistent grounding is essential. Constructed from copper, brass, or heavy alloy aluminum with copper-coated components, the clamp resists corrosion and wear while maximizing surface contact area to efficiently dissipate heat during operation.
Connection methods include LC40 style or oval-point screws with double internal threads or threaded ferrules, allowing tool-free attachment and detachment. The clamp supports cable sizes from 3/0 to 4/0, ensuring compatibility with standard welding equipment. Its reusable design eliminates temporary grounding solutions, reducing downtime and minimizing cable damage through built-in stress relief.
The clamp features serrated or swivel pads for secure gripping, a full jaw opening up to 3-3/8 inches, and a throat depth of 3-1/8 inches. A heavy-duty pressure screw applies up to 2,000 pounds of force for firm contact, while fin designs help lower operating temperatures. The clamp accommodates conductors up to 1-1/4 inches in diameter and is tested for fault currents up to 43 kA for 15 cycles, making it suitable for Metal Inert Gas (MIG) welding, industrial workstations, and environments requiring multiple grounding points.
