ELECTrIC SHOCK CAN KILL! Precaution-

MANUAL PLASMA CUTTING PACKAGE
The PowerCut-1250 / 1500 consoles are equipped with approximately 10-ft. of
4-conductor input power cable for 3-phase connection. If single-phase connection
is desired, tape back the red (lt. blue) wire on the input power cable. Connect the
single-phase input to the white and black wires only. When operating this machine
from a single-phase source, it must be connected to a dedicated 100 Amp feed.
Due to the higher input current requirements, the duty cycle of the machine is
lower than in three-phase operation. Single phase duty cycle is 60% for PC-1250
and 40% for PC-1500.
Connect your air supply to the inlet connection of the filter-regulator.
