TYPICAL OUTPUT VOLTAGE WAVEFORM - MACHINE LOADED
MACHINE LOADED TO 250 AMPS AT 26 VDC
This is a typical DC output voltage waveform generated from a properly operating machine. Note that
each vertical division represents 20 volts and that each horizontal division represents 2.00 milliseconds in
time.
NOTE:
Scope probes connected at the machine output terminals: (+) probe to electrode, (-) probe to work.
