92051230 - Tweco SGC-300 300 Amp Steel Work Clamp

Reliable Grounding for Professional Welding

The Tweco SGC-300 Steel Ground Clamp is an industry-standard work clamp designed to provide a secure and efficient electrical connection for your welding operations. Rated for 300 Amps, this clamp is engineered to handle the demands of medium-duty welding applications found in automotive shops, light fabrication facilities, and maintenance departments. A solid ground is critical for maintaining a stable arc, preventing voltage drops, and ensuring high-quality weld beads, and the SGC-300 delivers just that.

Constructed from high-quality zinc-plated steel, the body of the clamp is built to resist rust and corrosion, extending its service life even in harsh workshop environments. Unlike cheaper alternatives, the Tweco SGC-300 features a heavy-duty spring that maintains high gripping pressure over time. This pressure is vital for penetrating through light rust or mill scale on the workpiece, ensuring a low-resistance path for the welding current. The clamp is designed with a generous jaw opening of approximately 1.5 inches, allowing it to attach easily to various shapes, including plates, pipes, and structural angles.

Installation of the welding cable is straightforward, accommodating cable sizes up to 3/0. The efficient design minimizes heat buildup at the connection point, protecting your cable and ensuring consistent performance throughout the workday. Whether you are MIG welding mild steel or Stick welding repairs, the Tweco SGC-300 provides the reliability professional welders expect from the Tweco brand. It is a cost-effective solution that does not compromise on performance, making it a staple accessory for any welding machine setup.

At Josef Gas, we understand that accessories are just as important as the power source itself. This steel ground clamp is an excellent replacement or upgrade for worn-out clamps on 200A to 300A machines, ensuring your equipment operates at peak efficiency.
