6.10 pilot arc hi / lo and cut / mark circuits
A remote contact connecting 115V AC from J1-F to J1-L 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-400 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 425V DC Open Circuit Voltage to 360V* DC for Marking. A normally open con-
tact 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, and in the marking mode, it’s 12A.
