235116 - Miller 600 Amp C-Clamp Ground with 3/0-4/0 Terminal

Miller 235116 600A Work Clamp Overview

The Miller 235116 is a high-capacity Work Clamp designed for heavy industrial welding applications requiring up to 600 Amps of current. Unlike standard spring-loaded ground clamps, this unit utilizes a C-Clamp (screw-type) mechanism. This design allows the operator to apply significant torque when attaching the clamp to a workpiece, ensuring a mechanical connection that is both physically secure and electrically efficient. The clamp is engineered to accommodate large welding cables, specifically sized for 3/0 to 4/0 AWG, making it suitable for high-output power sources and heavy-duty welding cycles.

In professional welding setups, the integrity of the work connection (ground) is critical for maintaining arc stability and preventing equipment damage. The Miller 235116 addresses this by providing a large contact surface area and high clamping pressure, which minimizes electrical resistance at the connection point. Lower resistance translates to less heat generation at the clamp and more consistent voltage at the arc. The unit features a robust frame capable of withstanding the rough handling typical of shipyards, structural steel fabrication sites, and manufacturing plants.

The terminal connection on this clamp is designed for a lug attachment, ensuring that the heavy 3/0 or 4/0 cable is securely fastened to the clamp body for optimal current transfer. This specific model is an OEM replacement part for various Miller industrial welding systems but is also universally compatible with any welding power source requiring a 600A rated ground solution. The screw mechanism is durable and resistant to spatter buildup, ensuring long-term operability in harsh environments.

Technical Specifications:

• Part Number: 235116
• Amperage Rating: 600 Amps
