0000500415 - ESAB 400A Magnetic Welding Ground Clamp

High-Performance Grounding for Industrial Welding

The ESAB Magnetic Earth Clamp 400A (SKU: 0000500415) is a specialized welding accessory designed to provide a reliable and efficient electrical ground connection for high-amperage welding operations. Unlike traditional spring-loaded clamps or screw-type clamps that require a specific edge or protrusion to grip, this magnetic clamp utilizes a powerful magnet to adhere directly to the workpiece surface. This capability is particularly advantageous when working with large steel plates, tanks, or pipes where finding a suitable clamping edge is difficult or impossible.

Rated for a substantial 400 Amps, this earth clamp is engineered to handle the rigorous demands of heavy industrial welding, including MIG, TIG, and Stick processes. The device features a large contact surface area which is critical for maintaining low electrical resistance. Lower resistance ensures a stable arc, prevents the clamp from overheating, and guarantees consistent weld quality. The robust construction ensures durability in harsh workshop environments, resisting damage from heat, spatter, and impact.

One of the primary technical benefits of the ESAB Magnetic Earth Clamp is its ability to maintain a continuous electrical path without the need for tack-welding temporary ground tabs. In many fabrication scenarios, welders must waste time welding a tab onto a workpiece just to attach a ground clamp, only to cut and grind it off later. This magnetic solution eliminates that step entirely, streamlining the workflow and preserving the integrity of the base material. It is designed for use on ferrous metals and provides a secure hold that resists slipping during operation.

The unit is compact yet powerful, making it an essential addition to any professional welder's toolkit. Whether used in shipyards, structural steel fabrication, or general repair, the ESAB 400A Magnetic Earth Clamp delivers the performance and reliability required for precision welding tasks. Its design facilitates quick repositioning, allowing the welder to move the ground point closer to the weld zone easily, thereby reducing the risk of arc blow and improving overall arc control.
