Fast-Follow-Up Holders

The patented Fast-Follow Up (low inertia) holders are designed to maintain weld force during projection welding. The Fast-Follow Up holder uses an internal spring to keep the electrode in contact with the projection during the collapse, thus mimimizing expulsion and improving weld quality.

The Fast-Follow up holder is availablein three different shank diameters for direct cylinder mounting or a platen mount style for press welders.
