Review on 500A Electroplated Welding Ground Clamp - Manual Welder Copper Earth Clip (US & Dutch Types) by Alex Barr

Not sure how long it will last but it turned out to be very good. The clamp has a firm grip, but it's not fun to squeeze. The metal is strong enough not to bend or break. I soldered my cable to the included ring for better contact. Generally quite satisfied. A braided ground wire was added to ensure both sides of the clamp are well grounded, braided thinly so it melts a little when exposed to hot weld material, but I've had many clamps that had this problem, just not that many. But overall a good clip
