Machine Interface - Lincoln Electric Tomahawk 1000 Operator's Manual

TOMAHAWK ® 1000

mACHINE INTERFACE

The TOMAHAWK™ 1000 comes standard with a machine
interface. Interface signals provided include: arc start, arc
initiated, and arc voltage. These signals are accessible through
the 14 pin 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 connector. The circuit has a 15 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 connector. The circuit
provides a dry contact closure when the arc has transferred. Input
to this circuit 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 connector. The circuit provides full electrode to work arc
voltage (no voltage divider, 270VDC maximum).
