ECWG60C - Powerweld 600A Heavy-Duty C-Type Earth Clamp

High-Performance Industrial Grounding Solution

The Powerweld ECWG60C is a premium 600 Amp C-Style Ground Clamp designed for the rigorous demands of heavy industrial welding. In high-amperage applications, the integrity of the electrical circuit is paramount; a weak ground connection can lead to voltage drops, arc instability, and excessive heat generation at the contact point. This clamp addresses these issues through its robust C-frame architecture, which allows operators to apply significant mechanical torque, ensuring a bite that penetrates surface oxides and establishes a solid, low-resistance electrical path.

Constructed from a specialized high-conductivity copper alloy, the ECWG60C is engineered to handle continuous currents up to 600 Amps without overheating. The material selection balances electrical efficiency with mechanical durability, resisting deformation under tight clamping loads. Unlike spring-loaded clamps that rely on spring tension which can degrade over time due to thermal cycling, the screw-type mechanism of this C-style clamp maintains constant pressure indefinitely. This makes it particularly suitable for stationary setups, structural steel fabrication, and pipe welding where the ground placement is critical and does not need to be moved frequently.

The design features a wide throat and a flat contact surface, maximizing the area of engagement with the workpiece. This distribution of current density is crucial for preventing micro-arcing and localized melting at the contact interface. The cable connection point is designed to accommodate heavy-gauge welding cables (typically up to 4/0 AWG), securing them firmly to prevent pull-out or fraying. For MRO professionals and welding engineers seeking a reliable grounding solution that minimizes equipment downtime and maintenance, the Powerweld ECWG60C offers superior performance and longevity.
