      Good Clamp!

      It's a ground clamp, what else can I say. Well made and handles enough amps to get some quality welds laid down. Tweco is always a winner with these things!

      Great ground clamp

      This clamp is very favorable in comparison to the stock one on my welder.

      Best Ground Clamp you can buy

      I use these ground clamps on my MIG, TIG & plasma cutter. Probably overkill, but I don't have ground problems. These clamps are awesome. What else can you say.
