It appears that the Pipe Pro 450 RFC and the Axcess 450 are built on the same chassis and likely share virtually all of their hardware.

Can anyone tell me the difference between Pro Pulse on the Pipe Pro and Accu-Pulse on the Axcess Systems?

Both seem to hinge on pulsing with a shorter arc than traditional high voltage spray transfer pulsing; but not so short as to get into short circuiting like RMD does. Since the architecture of the PipePro/ Axcess machines are so similar, could it be that Pro/Accu Pulse are basically the same thing? Could a welder tell the difference between "Pro" and "Accu" in a blind test?
