The AB Tools 700 Amp Screw Type Earth Ground Clamp is an essential accessory for professional welders and hobbyists alike who perform Mig, Tig, or arc welding. It provides a secure, reliable electrical connection through a robust screw-driven jaw mechanism, ensuring stability during high-amperage tasks. While this clamp offers heavy-duty durability with its cast body and bronze lower jaw, users should be aware that the manual screw-tightening process takes slightly longer to adjust than traditional spring-loaded clamps.

Yes, it is suitable for TIG, MIG, and arc welding applications up to 700 amps.
The screw-type provides a much more secure and consistent pressure that does not degrade as the workpiece expands due to heat.
The cable is secured using two large grub screws located on the body of the clamp, providing a robust electrical connection.
No, you must grind the paint away to bare metal to ensure a proper ground connection for the welding arc.
The bronze jaw is an integrated part of the clamp assembly and is not typically sold as a separate field-replaceable part.
Clean the area where the clamp makes contact with the workpiece to remove rust, paint, or slag. Ensure the grub screws securing the cable are fully tightened.
Check that the cable connection is tight and free of corrosion. Ensure the clamp is not overloaded beyond its 700-amp capacity.
Apply a small amount of high-temperature lubricant to the screw threads and remove any metal debris trapped in the mechanism.
To set up the clamp, strip the end of your welding cable to expose the copper conductor and insert it fully into the cable entry port. Tighten the two grub screws evenly using an appropriate hex key until the cable is firmly locked in place. Regularly inspect the bronze jaw for weld splatter or oxidation, which can be removed with a wire brush to maintain a clean electrical path. Ensure the rubber insulation remains intact; if cracked or frayed, replace the handle grips immediately to maintain safety standards.
