WWWLGC-500 - Heavy-Duty 500A Copper Tong Earth Clamp

Reliable Grounding for High-Amperage Applications

In any welding setup, the quality of the ground connection is just as critical as the power source or the electrode holder. The LGC-500 Ground Clamp is engineered to meet the demands of heavy industrial welding, offering a robust solution for professionals who require consistent performance at higher amperages. Rated for up to 500 Amps, this clamp is designed to handle the heat and current flow associated with structural steel fabrication, heavy equipment repair, and pipe welding.

The LGC-500 features a classic tong-style design, also known as an alligator style, which is favored for its ease of use and versatility. The spring-loaded mechanism delivers substantial gripping force, ensuring that the jaws bite firmly into the workpiece. This strong mechanical connection is vital for penetrating through minor surface rust or scale, establishing a clean electrical path that minimizes resistance.

Superior Conductivity with Copper Construction

Unlike cheaper steel clamps that can overheat and cause voltage drops, the LGC-500 utilizes high-quality copper alloy jaws. Copper is the gold standard for welding grounds due to its superior electrical conductivity. By maximizing current transfer efficiency, this clamp helps to:

• Eliminate Arc Blow: A poor ground can cause magnetic interference that destabilizes the arc. A solid copper connection reduces this risk.
• Reduce Heat Buildup: High resistance generates heat. The large contact area and conductive material of the LGC-500 keep the clamp cooler during extended welding sessions.
• Extend Cable Life: By preventing overheating at the connection point, the clamp reduces thermal stress on your welding cable lugs and strands.

Installation is straightforward, featuring a standard bolt and nut connection point compatible with heavy-gauge welding cable lugs. Whether you are upgrading an existing machine or replacing a worn-out clamp, the LGC-500 provides the durability and electrical integrity required for professional results.
