ZORO SELECT 19N772 Ground Clamp 800A

This ground clamp is built for welding jobs that demand up to 800 amps of current. It suits professional welders and serious hobbyists who need a dependable connection on flat plates, pipes or round surfaces. The brass and steel body with a high-tensile spring grips tightly to keep the circuit secure during heavy use.

Current limit and cable range

The clamp handles a maximum of 800 A and accepts cable from 1/0 AWG up to 3/0 AWG. Its jaw opens to 3 1/4 in with a throat depth of 2 7/8 in, so it fits a range of workpiece thicknesses but cannot grip material thicker than that opening. The non-conductive design helps prevent accidental arcing on the operator side.

Ball-point screw installation

A ball-point screw secures the cable inside the clamp body, giving a firm mechanical bond without special tools. The main issue installers face is stripping the screw threads if the cable is overtightened or if the screw seats on insulation instead of bare conductor. Clean, bare wire and moderate torque avoid that problem.

Questions about this item

Should I choose the 1/0 AWG or 3/0 AWG cable size for this ground clamp?

The clamp accepts cables from 1/0 AWG up to 3/0 AWG; use the largest gauge your welder requires to keep resistance low and the connection secure.

What does the 800 A rating mean when I am actually welding?

It is the maximum continuous current the brass jaws and ball-point screw can carry without overheating, so the clamp will not become the bottleneck on heavy-duty jobs.

How does the ball-point screw connection limit what I can do?

The screw locks the cable firmly in place but only fits 1/0 to 3/0 AWG conductors; smaller or larger cables cannot be secured properly.
