2.12 Voltage Divider adjustment
The PCC-14 contains a voltage divider board used for lift assemblies that make use of voltage height
control . The voltage divider can be adjusted to accurately reflect the arc voltage during cutting opera-
tions for voltage height control .
You can set the ratio by adjusting the resistance of R1 . To set R1 to a specific value, measure the re-
sistance between points W2 and W3 on the voltage divider board . See the illustration of the voltage
divider board below . The chart below outlines some common ratios and resistance values .
