OKIWG2 - 200 Amp Steel Welding Work Clamp

Reliable Electrical Grounding for Welding Operations

The 200 Amp Steel Ground Clamp (SKU: OKIWG2) is a fundamental component designed to establish and maintain a secure electrical circuit during welding processes. In any arc welding system, the quality of the ground connection—technically referred to as the work connection—is just as critical as the welding torch or electrode holder. This specific model is engineered to handle up to 200 amperes of current, making it an excellent choice for light to medium-duty industrial applications, maintenance workshops, and vocational training centers.

Constructed from stamped steel, the body of the clamp provides superior mechanical strength compared to cast copper alloys, allowing it to withstand the rigors of daily shop use, including drops, impacts, and dragging across concrete floors. While steel has higher electrical resistance than copper, this clamp is designed with optimized contact geometry and strong spring tension to ensure a low-resistance interface with the base metal. The heavy-duty spring mechanism exerts significant pressure, allowing the jaws to bite through minor surface contaminants such as rust, mill scale, or paint, thereby facilitating a consistent flow of electrons. This is crucial for maintaining arc stability, preventing voltage fluctuations, and ensuring uniform weld bead deposition.

Thermal management is another key aspect of the OKIWG2's design. Poor connections often lead to resistive heating, which can damage welding cables and reduce the duty cycle of the equipment. By ensuring a tight, broad area of contact, this clamp minimizes heat generation at the connection point. The unit features a straightforward cable installation system, typically utilizing a bolt-down mechanism or lug attachment point, which accommodates standard welding cable sizes appropriate for 200-amp service. It is compatible with a wide range of power sources, including transformer-based and inverter-based machines for SMAW (Stick), GMAW (MIG), and GTAW (TIG) welding.

For professionals seeking a cost-effective yet robust solution for their grounding needs, this steel ground clamp offers the necessary durability and electrical performance. It serves as a reliable replacement for OEM clamps that may have lost their spring tension or suffered from contact erosion over time.
