Tweco 500 A ground clamp
The Tweco 358-9205-1250 is a welding ground clamp rated for 500 A maximum current. It suits welders who need a reliable return path on flat plates. The copper clamp body and brass connection material conduct high current efficiently. An insulated spring on the steel handle helps protect the operator during arc flash events.
500 A capacity with 2 in jaw opening
The clamp accepts workpieces up to 2 in thick thanks to its maximum jaw opening and 1 3/4 in throat depth. It handles heavy-duty welding jobs within the 500 A rating without overheating. Beyond that current level the connection may become a bottleneck. The ball-point screw cable connection secures leads firmly for consistent conductivity.
Arc flash protection and insulated handling
Arc flash protection is built into the design through the insulated spring and HAWA material. The steel handle stays cooler during extended runs while the spring reduces heat transfer to the operator's hand. Copper and brass components minimise resistive heating at the contact faces. Normal use produces minimal thermal stress on the clamp itself.

Questions about this item
Will the 500 A ground clamp work with my older welder that uses a ball-point screw cable connection?
Yes, the clamp uses a ball-point screw cable connection, so it will attach to any compatible cable with the same fitting.
How can I verify the clamp is making proper contact after installation?
Check that the jaws close fully on the flat plate, the insulated spring holds firm pressure, and the brass connection seats tightly against the copper body.
Does the package include welding cable or only the clamp assembly?
Only the ground clamp is supplied; welding cable and any lugs or connectors must be purchased separately.
