Earth Clamp 300Amp

A 300-amp earth clamp is a heavy-duty, spring-loaded grounding device designed to provide a secure electrical connection between a welding machine and a workpiece, handling currents up to 300A for MIG, TIG, and ARC welding. Typically made of brass, copper, or steel, it features high-conductivity contact points, a robust spring for strong gripping force, and a cable connection stud.
