K910-2 - Lincoln GC-500 Spring Loaded Ground Clamp 500A

Fast and Secure Welding Connections

Maximize your welding efficiency with the Lincoln Electric GC-500 Work Clamp, a robust 500-amp grounding tool built for speed and reliability. In the welding industry, time is money, and the K910-2 is designed to eliminate the hassle of fiddling with slow screw-type clamps. Featuring a high-tension spring design, this clamp offers effortless operation: just squeeze the handles to open the jaws and release to secure it to your work. There are no bolts to tighten or loose parts to misplace, ensuring you can move your ground quickly as you work around large assemblies.

The GC-500 is a powerhouse, rated for 500 amps at a 60% duty cycle. This high amperage rating makes it suitable for the most demanding welding processes, including heavy flux-cored welding and air carbon arc gouging within its range. The jaws feature a wide 2-1/2 inch (63 mm) opening capacity, allowing you to easily attach to diverse surfaces such as table edges, heavy pipe sections, and thick metal plates. The strong spring pressure ensures the jaws maintain positive contact, preventing the clamp from slipping and reducing the risk of arc wander caused by poor grounding.

Installation is simple and secure. The GC-500 is designed for a direct cable lug connection. Your welding cable lug bolts directly to the clamp structure, creating a solid, high-conductivity joint that minimizes voltage drop. This direct connection is superior to designs that rely on pressure contacts or indirect paths, ensuring that the full power of your machine reaches the arc. This design also reduces heat buildup at the connection point, protecting your cable and clamp from overheating.

Built to last, the GC-500 features a rugged steel and copper construction that resists spatter and mechanical impact. It is an ideal replacement or upgrade for standard work clamps included with many industrial power sources. From automotive repair shops to heavy equipment maintenance, the Lincoln GC-500 Work Clamp delivers the secure ground you need for flawless welds every time.
