Rotary Chassis and Chassis Magnets
Rotatable Earthing Couplings
For the construction of tanks, piping and related equipment
An effective ground connection to the workpiece is essential for perfect manual or automatic welding. Increasing demands on the quality of welded parts necessitate the use of specially developed current conduction elements. In most cases, this eliminates a common source of problems.
Current Couplings TYPE NKK
For current loads between 400 and 2000 A
For rotating workpieces, a current-coupled earth connection is the safest and best solution. This extremely robust, rotatable current conductor is built to withstand rough handling.

Clamp Head Chassis Pliers TYPE K2
For tank, steel and shipbuilding.
Suitable for use with existing NKK 800 or NKK 1200 for rotating workpieces
The strong screw body and brass head is a general purpose earth coupling.
The clamp head can be fixed to the existing coupling by axially to the rotational movement
radial rotational motion
or at any angle between these positions.
The body and the screw part are isolated from each other so that no arcing of the pliers and the material is possible.
