OPERATION

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).
