92101150 - Tweco GC-600-50 Copper Ground Clamp 500A

High-Performance Grounding for Industrial Welding

The Tweco Model GC-600-50 is a premium copper ground clamp designed to meet the rigorous demands of high-amperage welding applications. Engineered with a focus on conductivity and durability, this clamp features a body cast from a high-grade copper alloy. This material choice ensures superior electrical transfer, minimizing resistance and heat buildup at the contact point, which is critical for maintaining a stable welding arc over long durations. With a maximum amperage rating of 500 A, it is well-suited for heavy-duty fabrication and structural welding tasks.

Functionality is at the core of the GC-600-50's design. It utilizes a ball-point screw mechanism to secure the welding cable to the clamp body. This method provides a mechanical connection that is both tight and resistant to loosening under thermal cycling, ensuring that the current path remains uninterrupted. The clamp is also equipped with a heavy-duty spring that delivers substantial clamping force. This pressure is vital for penetrating surface oxides or minor contaminants on the workpiece, establishing a solid electrical ground immediately upon application.

The physical dimensions of the clamp enhance its versatility. It boasts a generous jaw opening of 2-1/2 inches and a throat depth of 1-3/8 inches, allowing it to grip a wide variety of workpiece shapes, including flat plates, beams, and pipe sections. The spring is insulated, adding a layer of safety and protection against inadvertent arcing. While designed primarily for general high-amperage grounding, the GC-600-50 is also compatible with the Tweco Roto-Ground device, offering flexibility for shops that utilize rotating fixtures. This clamp represents a reliable solution for professionals seeking to optimize their welding circuit efficiency.
