23892433 - ESAB No. 21 Welding Ground Clamp

Reliable Grounding for Precision Welding

The ESAB Work Clamp No. 21 is an essential component for establishing a secure and efficient electrical circuit in welding operations. A high-quality ground connection is critical for maintaining a stable arc, preventing voltage drops, and ensuring consistent weld penetration. This clamp is engineered to provide a firm grip on the workpiece, minimizing electrical resistance at the contact point. Poor grounding is a common cause of welding defects, including porosity and erratic arc behavior; the No. 21 clamp addresses this by utilizing a robust spring mechanism that maintains constant pressure against the metal surface.

Constructed with durability in mind, the clamp is designed to withstand the harsh conditions typical of industrial environments, including exposure to heat, spatter, and mechanical impact. The contact surfaces are shaped to bite through light rust or scale, ensuring a conductive path is established quickly. The compact form factor allows for placement in confined spaces where larger clamps might be obstructive, making it a versatile tool for various fabrication setups.

Integration into existing welding cable assemblies is straightforward, with connection points designed for secure cable termination. Whether used for light-duty repair work or more demanding fabrication tasks, the ESAB No. 21 Work Clamp delivers the performance reliability expected from a leading manufacturer in the welding industry. Its carded packaging ensures the product arrives protected and ready for immediate deployment in the workshop.
