Machine interFace For raw arc Voltage
remove the power supply cover and Mylar barrier
Connecting a cable to the Powermax65/85 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. Using a TORX or blade screwdriver, remove the 8 small screws (2) from the power supply cover.
3. Using a TORX or blade screwdriver, remove the 8 large screws (1) from the power supply cover.
4. Lift the cover (3) off the power supply.
5. Remove the Mylar barrier from the power-board side of the power supply. The Mylar barrier is flexible and can be
bent slightly for removal.
