OVERVIEW

Reliable 300 Amp Grounding Solution

The Tweco 300 Amp Steel Ground Clamp (Model WS300SG) is designed to provide a secure and consistent electrical connection for medium-duty welding applications. In any welding circuit, the ground clamp is a critical component; a poor connection can lead to unstable arcs, increased resistance, and overheating. This clamp addresses those issues with a robust design tailored for industrial environments where durability and reliability are paramount.

Constructed from high-grade steel, this clamp is built to withstand the physical abuse typical of fabrication shops and construction sites. While copper offers higher conductivity, steel provides superior structural integrity and cost-effectiveness for general-purpose welding up to 300 amps. The unit features a heavy-duty spring mechanism that delivers high clamping pressure, ensuring the jaws bite through rust, scale, or paint to establish a solid electrical contact with the workpiece.

The "Crocodile" style jaw design allows for versatility in clamping, easily gripping flat plate, pipe, or irregular shapes. Installation of the welding cable is straightforward, utilizing a mechanical connection that ensures the cable remains secure during operation. Whether you are setting up a new welding station or replacing worn-out equipment, the WS300SG offers the performance required for professional results.

FAQ

This ground clamp is rated for a maximum of 300 Amps.

The clamp body is constructed from durable steel.

The cable typically connects via a bolt-on lug or mechanical fastener terminal on the clamp.

Yes, as long as your welding amperage is within the 300A rating, it is suitable for TIG, MIG, and Stick welding.

Mechanical clamps like this generally provide a more secure electrical connection on non-flat surfaces compared to magnetic grounds, though magnets are faster for quick tacking on flat steel.

Yes, you can use it on aluminum, but ensure the contact points are clean to prevent contamination and ensure good conductivity.

While exact specs vary, 300A clamps of this style typically open between 1.5 to 2 inches.

No, this is the clamp only. You must attach it to your existing welding cable.
