Machine interface for raw arc Voltage
Remove the power supply cover and component barrier
Connecting a cable to the power board to bypass the voltage divider and access raw arc voltage must be done by
trained service personnel.
Connecting directly to the plasma circuit for access to raw arc voltage increases the risk of
shock hazard, energy hazard, and fire hazard in the event of a single fault. The output voltage
and the output current of the circuit are specified on the data plate.
1. Turn OFF the power, disconnect the power cord, and disconnect the gas supply.
2. Remove the screws from the power supply cover.
Note: Powermax65/85 system covers have 8 small screws (2) and 8 large screws (1). All 16 screws for
Powermax105/125 covers are the same size.
3. Lift the cover (3) off the power supply.
4. Remove the component barrier from the power-board side of the power supply. The component barrier is flexible
and can be bent slightly for removal.
