MACHINE INTERFACE
The PRO-CUT 80 comes standard with a machine
interface. Interface signals provided include: arc start,
arc initiated, and arc voltage. These signals are acces-
sible through the 14 pin MS connector on the case
front.
ARC START:
The Arc Start circuit allows for triggering of the power
source to commence cutting. This circuit can be
accessed through pins K and M of the 14 pin MS con-
nector. The circuit has a 17 VDC nominal open circuit
voltage and requires a dry contact closure to activate.
ARC INITIATED:
The Arc Initiated circuit provides information as to
when a cutting arc has transferred to the work piece.
This circuit can be accessed through pins I and J of the
14 pin MS connector. The circuit provides a dry contact
closure when the arc has transferred. Input to this cir-
cuit should be limited to 0.3 A for either 120VAC or
30VDC.
ARC VOLTAGE:
The Arc Voltage circuit can be used for activating a
torch height control. This circuit can be accessed
through pins D and G of the 14 pin MS connector. The
circuit provides full electrode to work arc voltage (no
voltage divider, 335VDC maximum).
Users wishing to utilize the Machine Interface can
order a K867 Universal Adapter (please adhere to the
pin locations stated above) or manufacture a 14 pin MS
connector cable assembly.
