92101202 - Tweco GC-600 Heavy-Duty Copper Ground Clamp 600A

Reliable Grounding for Heavy Industry

The Tweco GC-600 Ground Clamp (SKU: 92101202) is a staple in the heavy fabrication industry, known for its robust construction and reliable performance. When it comes to welding, the quality of your ground connection is just as critical as the quality of your torch or electrode holder. A poor ground can lead to arc instability, voltage drops, and poor weld quality. The GC-600 is designed to eliminate these issues by providing a solid, high-conductivity connection to your workpiece.

Manufactured by Tweco, a leader in welding accessories, this clamp is rated for 600 Amps at a 60% duty cycle, making it suitable for demanding applications such as structural steel erection, shipbuilding, and heavy equipment repair. The clamp features jaws made from a special copper alloy. Unlike stamped steel clamps that can overheat and lose conductivity over time, the copper alloy jaws of the GC-600 effectively dissipate heat and maintain excellent electrical contact.

One of the standout features of this model is its clamping mechanism. It utilizes a heavy-duty spring that delivers substantial holding power. This high pressure helps the jaws bite through thin layers of rust, scale, or paint, ensuring a good electrical path without the need for excessive surface preparation. The clamp is designed to handle welding cables ranging from size 3/0 to 4/0, accommodating the heavy cabling required for high-amperage power sources.

At Josef Gas, we understand that durability is key. The Tweco GC-600 is built to withstand the rough environment of a welding shop. Its streamlined design minimizes the risk of snagging on obstructions, and the rugged materials resist spatter and mechanical impact. Whether you are upgrading your existing equipment or outfitting a new welding station, the GC-600 provides the assurance of a stable arc and consistent weld parameters.
