Marking with two parallel EPP -360's

Two EPP-360's, connected in parallel, and can be used for marking down to 10A
and cutting from 30A up to 720A.
Operation of two parallel EPP-360's:
Provide start/stop, Cut/Mark, "HI CURRENT" logic signals and either logic or analog
inputs to control the pilot current signals to primary unit for both cutting and marking.
When marking, both power sources are powered up, but the mark signal disables
the output of the supplemental power source.
