ALWAYS USE GENUINE LINCOLN
ELECTRIC ELECTRODES AND
VORTECH™ NOZZLES
• Only Genuine Lincoln Electric consumables yield
the best cutting performance for the PRO-CUT 55.
• The patented VORTECH™ nozzle provides an
extra “kick” of swirl as the arc exits the nozzle which
improves cutting performance. No other nozzle has
this capability or can match its performance.
GENERAL OPTIONS /
ACCESSORIES
The following options/accessories are available for
your PRO-CUT 55 from your local Lincoln Distributor.
K1600-1 Undercarriage - A valet style undercarriage
with pull-out handle for machine only. Provides Torch
and Work Cable storage.
S22147-043 - VORTECH™ nozzle with an .043” (1.2
mm) Orifice
S22147-068 - VORTECH™ nozzle with an .068” (1.7
mm) Orifice
S22149 - Electrode - replacement electrodes for cut-
ting.
S22150 - Shield Cup - This shields the torch tip and
provides more visibility to the workpiece than the drag
cup.
• Note: The shield cup does not prevent the torch tip
from touching the workpiece.
S22151 - Drag Cup - The drag cup protects the torch
by preventing the torch from touching the workpiece.
K1571 Series - PCT 80 Torches come in 25’ and 50’
lengths in either hand held or mechanized versions.
K1678-1 MACHINE INTERFACE KIT
This kit is compatible with the present models of the
Pro-Cut 55. Machines having code numbers 10473
and 10474 may require their Output PC Board to be
upgraded to a G3326-2 board.
This kit provides the necessary hardware and instruc-
tions to install a14 Pin MS Type remote connector into
the machine. This connector provides provisions for
the following interface signals between the Pro-Cut 55
and the controller.
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 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 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.
