The funniest groundclamp I've ever welded with was a 1/4" plate with a 16 gauge plate welded to it, and hammered down onto the exposed ground cable. Can't say I miss that shop!
Hopefully this works! I tacked the ground onto the part In the said shop. In the said shop, I had to pull teeth to get an all position wire...

They would just zap-tack an uphill, and downhand a metalcore weld overtop.
