Tweco Roto-Ground Heavy Duty Rotary Ground Clamps
Tweco Roto-Ground is a highly efficient device for grounding weldments while being rotated on turning rolls or positioners. The 2” shaft shoulders up to a steel nut which the user welds to rotating work or fixturing.
Tweco Roto-Grounds have no brushes, springs or mercury. A simple tension adjusting bolt provides maximum efficiency.
