Grounding Clamps for Welding

Designed specifically for use with welding circuits.

Plier Clamp


Nonconductive

Plier clamps are good for light duty applications that require mobility, such as building a fence.

Copper Connection—Clamps that are copper prevent weld spatter from sticking.

Nonconductive—Nonconductive clamps won’t transmit electricity, meaning you can touch them while the power is on without disrupting the circuit.

Cable Support—Cable supports prevent cable strand breakage.

Pliers Clamps for Welding Tables

Mount these clamps anywhere on your welding table in seconds. They have a press-fit pin that fits into the standard _5/8" dia. holes on most tables—no additional hardware required. When working with taller workpieces, mount these clamps onto fixturing squares or riser blocks for additional height clearance. Turn the crank handle to adjust the opening size. Once your workpiece is in place, squeeze the handle to lock the clamp. To release, pinch the lever under the handle.
