  • Brass body with braided copper shunt conducts current efficiently
  • Non-conductive design adds operator safety during use
  • Compact 8.9 in length fits tight workspaces easily

Ground Clamp 300 A Arc Welder

This ground clamp is built for arc welding setups that require a secure, high-current connection to the workpiece. It suits welders and fabricators who need reliable grounding on flat plates, pipes or round surfaces during daily shop or field work.

300 A Current Limit and Cable Range

The clamp handles a maximum current of 300 A and accepts cable gauges from 2 AWG up to 1/0 AWG. Its braided copper shunt provides the electrical link, while the brass body and steel connection parts conduct current within this defined ampacity window.

Jaw Capacity and Workpiece Fit

A maximum jaw opening of 2 in and a throat depth of 3 5/16 in determine the thickest plate or largest pipe the clamp can grip. The high-tensile spring maintains tight contact on compatible shapes, but the fixed dimensions restrict use on oversized structural sections.

Questions about this item

Should I choose the 300 A model or a different amperage for my arc welder?

This ground clamp is rated for a maximum current of 300 A, so select it when your welding machine operates at or below that amperage.

What does the 300 A rating mean when I am actually welding?

It means the clamp can continuously carry up to 300 amps without overheating, ensuring a stable ground connection during heavy-duty arc welding.

How does the braided copper shunt connection affect the clamp's performance?

The braided copper shunt provides a flexible, high-conductivity link between the welding cable and the brass clamp body, minimising resistance at the connection point.
