OKIWG5 - Heavy-Duty 500A Steel Welding Work Clamp

High-Performance 500 Amp Steel Ground Clamp for Industrial Welding

The OKIWG5 is a robust 500 Amp steel ground clamp designed to meet the rigorous demands of heavy-duty industrial welding environments. Establishing a solid earth connection is critical for maintaining arc stability, reducing voltage drop, and ensuring high-quality weld deposition. This clamp is engineered with a high-grade steel body, offering superior mechanical strength and resistance to deformation under thermal stress compared to lighter-duty alternatives. Its design prioritizes longevity and consistent performance, making it an essential component for professional fabrication shops, shipyards, and structural steel operations where equipment is subjected to daily abuse.

Rated for a continuous current of 500 Amperes, this ground clamp is capable of handling high-heat applications without overheating or losing conductivity. The steel construction provides a durable frame that withstands the rough handling typical of industrial worksites, including drops and impacts. While copper offers higher conductivity, the strategic design of this steel clamp incorporates large contact areas and high-tension springs to ensure low contact resistance. This balance of durability and electrical efficiency makes it a cost-effective solution for high-amperage MIG, TIG, and Stick welding processes where reliability is paramount.

The clamping mechanism features a powerful spring that delivers substantial gripping force. This ensures the jaws bite firmly onto the workpiece, penetrating through minor layers of rust, scale, or paint to establish a clean electrical path. A secure ground is vital for preventing arc wander and protecting the welding power source from electrical feedback. The wide jaw opening accommodates a variety of workpiece thicknesses, from thin sheet metal to thick structural beams, providing versatility across different projects and setups.

Installation of the welding cable is straightforward, typically utilizing a bolt-on or lug connection that ensures a tight, vibration-resistant interface between the cable and the clamp. This secure termination point minimizes resistance at the connection, preventing heat buildup that could damage the cable insulation or the clamp itself. By maintaining a cool and efficient ground path, the OKIWG5 helps welders achieve consistent bead profiles and reduces the frequency of contact tip burnback caused by poor grounding.
