6.10 high / low cut current modes and mark mode
A remote contact connecting 115V AC from J1-R to J1-S places the Pilot Arc in High by operating K8. Note, that for this func-
tion to operate, the Pilot Arc Hi/Lo switch on the front panel must be in the “LO” position.
The EPP-601 is placed in the Marking mode when a remote contact connecting 115V AC from J1-R to J1-C operates K11. In
the Marking mode, a normally closed contact on K11 opens turning off K10. When K10 turns off, the Boost supply is discon-
nected lowering the normal Cutting Mode 430V DC Open Circuit Voltage to 360VDC for Marking. A normally open contact
on K11 activates K12. K12 connects the I (min) resistors necessary for stabilizing the low currents required for marking. In
the Cutting mode, the minimum stable output current is 50A in the high current range, 35A in the low current range and
10A in the marking mode. In the marking mode, the normally closed contacts K11(3, 9) and K11(1, 7) open. This deactivates
K13 and K14 placing the power source in the low current range.
