for Hypertherm with CPC
20:1 Standard on some
Thermal Dynamics, others
To set PWM SENSOR ratio divider option:
1. Turn case over. There is a small access slot for the
Prescale Jumpers
2. Determine the proper setting for the type setup you have.
3. Set the small option jumper to match.

UNITS ARE SHIPPED TO MATCH THE RAV-01 (7:1)
RATIO. USE THE CHART BELOW IF YOU ARE USING
THE MODULE WITH A PLASMA WITH AN INTERNAL
VOLTAGE DIVIDER. SEE THE SECTION ON
CONNECTING A PLASMA WITH AN INTERNAL
VOLTAGE DIVIDER TO DETERMINE TE PROPER RATIO
IMPORTANT:
The Hypertherm 45 has an
internal voltage divider. It
cannot be changed from the
50:1 ratio. Set your PWM
Sensor jumper to the 50:1
position if you are using the
MIC-01 Direct Connect
Cable.
