Excellent replacement for the weld clamp. It seemed cheap at first because it's thin metal, but it clamps well and makes a good connection. The actual copper part that touches the weld part is of good quality, which is important.
I didn't like that they sent me a grounding clamp designed for a 150 amp welder. Now I have to drive to the next town to return it to the UPS branch to get a refund one day!

The size of the wire bolt was so small that I didn't have a ring terminal small enough to fit on it that would also fit myโฆ
