Ground clamp for arc welding
This brass ground clamp is rated for 300 A and accepts cable from 2 AWG up to 1/0 AWG. It connects via a ball-point screw and uses a high-tensile spring to grip flat plates, pipe or round surfaces. The non-conductive body prevents stray current paths during arc welding work.
300 A rating matches your welder output
The single specification that decides fit is the 300 A maximum current; choose this clamp only when your power source does not exceed that figure. The jaw opens to 1 1/2 in with a throat depth of 2 3/8 in, so verify the workpiece thickness before ordering.
Brass body runs cool at rated load
Brass construction and the screw connection keep resistance low, so the clamp body stays near ambient temperature during normal 300 A use. No cooling fan or liquid circuit is present, making operation silent. Overall length is 7.9 in and height is 1.1 in for a compact fit on the bench.

Questions about this item
What does the 300 A rating mean when the clamp is on a real workpiece?
The clamp is rated to carry up to 300 amperes of welding current without overheating, provided the cable and connection are sized for the same load.
How does the ball-point screw connection limit the cable size I can use?
The screw accepts cable from 2 AWG up to 1/0 AWG; larger conductors will not fit the terminal.
What clearance do I need to mount this 7.9 in clamp on a flat plate or pipe?
The jaws open 1 1/2 in with a 2 3/8 in throat depth, so the workpiece must fit within that gap and depth.
