81F13 - ESAB GC-500 Style Heavy Duty Earth Clamp

Heavy-Duty Grounding Solution

The ESAB 81F13 is a high-performance 500 Amp ground clamp designed for demanding industrial welding environments. Proper grounding is essential for the safety of the welding equipment and the quality of the weld itself. This clamp is engineered to handle high amperages without overheating, thanks to its substantial copper alloy contact points and robust construction.

In professional fabrication settings, a poor ground connection can lead to arc instability, increased spatter, and potential damage to the welding machine's internal components. The 81F13 mitigates these risks by providing a large surface area contact and high clamping pressure. The heavy-duty spring mechanism ensures that the clamp remains securely attached to the workpiece, even when the cable is pulled or repositioned.

This unit is compatible with a wide range of welding processes, including MIG, TIG, and Stick welding, where currents up to 500 amps are required. The design facilitates easy cable installation, typically utilizing a lug or bolt-on connection that ensures a tight, low-resistance electrical path from the cable to the clamp body.

Key Technical Benefits:

• High Conductivity: Copper alloy jaws minimize resistance and heat buildup.
• Thermal Durability: Designed to withstand the thermal cycles of heavy welding.
• Mechanical Strength: Reinforced body resists deformation under stress.
