A.1 Pneumatic Curves (Pulse Tool) (continued)
Double-Hit:
This picture shows the curve generated by a double hit. Notice how the curve immediately
steps up to line pressure and stays there. There is little or no pulsing region. This curve
would be typical of a fastener being “hit” again after the fastener had already been
tightened to torque.
