Review on Enhance Welding Safety with Lincoln Electric 300 Amp Grounding Work Clamp - Model# KH525, Original Version by Mike Starling

This grounding clamp really is a bargain. It costs about the same as the Harbor Freight counterpart, but looks a lot better, and the shape of the copper parts is better and twice the thickness. The only problem for me is that the spring is so strong that I had to use two hands to open it, whereas the Harbor Freight can be operated with one hand. I didn't think I needed such an efficient grounding clamp so I returned it. But for someone with a strong hand, this would be a great clamp.
