The Key Plant Port A Weld allows for simplified torch positioning when parts vary in shape and size. The column includes 360° rotation, allowing it to rotate and position the welding head over multiple welding positioners or other fixtures.

The PWS is a self-contained, compact welding manipulator system that can be integrated as a turnkey solution with a variety of welding processes like, GMAW, GTAW and SAW.
