I suspect it may be a ground clamp for welding structural steel. The ground lead back to the welder would have attached to the loop, then you clamp it onto the I-beam or whatever. Just a guess..........
All the Best,

It is a ground clamp for grounding different parts of a structure like a wellhead to a drilling rig, any place that a good ground is needed. We used them when rigging explosive perforating guns to prevent stray currents from drilling rig generators that could cause an electric blasting cap to accidentally detonate. We had a long 2 Ga stranded insulated ground lead mounted in the back of the wireline perforating truck and used this type clamp to ground the truck to the well head. another ground cable (like a booster cable) was used to ground the drilling rig to our truck and the well head. I would say it could also be used on a welder.
