unit begins pulsing immediately.
Following the shutdown the unit continues to pulse regardless

Mode
Under high power operation (Power or Current regulation),
Ignition
pulsing is disabled, the voltage jumps to maximum voltage
(~1350 V) and is held until the current is detected flowing
above 2.0 A. At this time pulsing is started.
Should 100 ms expire before pulsing begins, a duty cycle is
imposed on the unit's voltage limit to prevent the unit from
being damaged. This duty cycle is 100 ms at maximum
voltage and 900 ms at the user voltage limit. This cycle will
repeat until the current is detected flowing above 2.0 A at
which time pulsing is started.
Note: If the regulation mode is Voltage, the output on voltage
