This is the typical AC output voltage waveform generated from a properly operating machine. Note that each vertical division represents 50 volts and that each horizontal division rep- resents 2 milliseconds in time. Note: Scope probes connected at machine output terminals: (+) probe to electrode, (–) probe to work.
This is the typical DC (+) output volt- age waveform generated from a prop- erly operating machine. Note that each vertical division represents 50 volts and that each horizontal division represents 2 milliseconds in time.
