Nies rotary ground clamps

Nies rotating current couplings and earth clamps

When the workpiece rotates during welding, the welding current still has to flow reliably. Nies current couplings and rotatable earth clamps transmit welding currents from 400 to 4000 A and give a safe earth connection on rotating workpieces, shafts and machine components.

Typical applications are tank, pipeline and equipment construction: tank shells and heads, pipes and rotating shafts. The range includes heavy-duty current couplings, swivelling clamp heads, earth couplings with magnetic or mechanical clamping and couplings for axial connection to shafts.
