The navi detects with a high accuracy whether or not the nut and the workpiece are set correctly right before welding.
It prevents manufacturing defectively welded products.

When pressured, the guide pin is pressed by the upper electrode to descend.
This height difference determines whether the nut is set correctly or not.

Examples of incorrect nut setting
navi detects incorrect nut/workpiece setting and looseness of electrode and guide pin.
