NORMAL OPEN CIRCUIT WELD VOLTAGE WAVEFORM (CV MODE)

HIGH IDLE - NO LOAD - OUTPUT CONTROL AT MAXIMUM

CH1

0 volts

20 volts

5 ms

This is the typical CV output voltage generated from a properly operating machine. Note that each vertical division represents 20 volts and that each horizontal division represents 5 milliseconds in time.

Note: Scope probes connected at machine output terminals.

SCOPE SETTINGS

Volts/Div	20V/Div.
Horizontal Sweep	5 ms/Div.
