2 Introduction
2.1 Overview
EtchArc Plasma Marker
The EtchArc Plasma Marker is a constricted arc
plasma torch marking device. The plasma marker
is a low amperage plasma torch designed for high
accuracy line marking on metal plate. It produces
high quality, durable marks at speeds between 100
and 500 inches per minute. It can greatly enhance
production by performing plate layout and marking
with computer controlled accuracy and speed.
The plasma marking process is similar to the
plasma cutting process. However, rather than
making a cut into the plate, the low amperage
plasma arc merely marks the plate in the pattern
produced by the machine motion. Voltage height
control maintains a constant torch standoff for
consistent marking. This allows for high speed,
highly accurate pattern layout.
When the EtchArc Plasma Marker is used in
conjunction with ESAB’s Vision CNC, Dynamic
Current Control is used to precisely control width
and depth of marks by proportionally ramping
current up and down as the machine accellerates
and decelerates. This minimizes cratering or pitting
on starts, in corners, and at the end of the mark.
The Plasma Marker system is intended to be used
during an automatic cutting cycle. Accurate
positioning of the layout lines and marks depends
on using the automatic marker offsets executed by
the CNC during Automatic Mode. However, the
marker can be used manually for the purpose of
testing and setup.
For automatic operation the control will execute the
necessary steps, according to the part program, to
offset the torch, turn on the Automatic Height
Control, fire the torch, and begin marking.
For manual operation, all of these steps must be
performed by the operator.
Introduction Page 5
Section 2
2.2 System Description
The Plasma Marking System consists of a modified
PCM-500i plasma power supply, a marker add-on
box, the marking torch, and Argon supply regulator.
The PCM-500i is an inverter power supply capable
of supplying 35 Amps. It is modified to interface
with a CNC, and the manual controls are disabled
to prevent accidental misadjustment.
The marker add-on box interfaces the marking
torch to the power supply, providing the necessary
electrical connections, pilot arc control, and
additional gas control.
The marking torch is designed for simplicity and
long consummable life. There are only three
consummable parts, the electrode, nozzle, and
shield cup. Argon cut gas provides long electrode
and nozzle life.

- The Fault lamp should be off.
Setup Page 9
Section 4
4.2 Gas Setup
The Plasma Marking System uses two compressed
gases for operation. Compressed air is used for
electrode cooling and shield gas, Argon is used as
the plasma gas. The plasma gas constricts the arc
as it exits through the nozzle orifice. The shield gas
creates a secondary shield around the arc, and
improves torch cooling.
Before operating the system, be sure to check the
gas pressure settings for both compressed gases.
The TEST/OPERATE switch on the front panel of
the PCM-500i allows the operator to preset the
pressure for both gases. Set this switch to the
TEST position to energize the solenoid valves for
both compressed air and Argon.
At the PCM-500i, adjust the Air Pressure Regulator
on the rear of the unit while obse rving the pressure
gauge on the front of the unit. Set the pressure to
90 PSI while the air is flowing.
The Argon pressure is adjusted at the separate
regulator panel mounted to the cutting machine.
While the Argon is flowing, set the pressure to 75
PSI.
When finished adjusting the gas pressures, set the
TEST/OPERATE switch back to the OPERATE
position.
Page 10 Setup
4.3 CNC Setup
EtchArc Plasma Marker
The EtchArc plasma marker may be interfaced to
any cutting machine CNC. The following
parameters may or may not be supported by your
interface. Prior to plasma marking, check these
parameters, or their equivalents, at the machine
control:
Standoff
Initial Height
Marker Remote
Current
On the Vision CNC, this parameter adjusts the
actual cutting height (or arc voltage) that the torch
will maintain, after the arc has started.
Sets the distance to raise the torch after sensing
the plate. When VHC is turned on, the torch will
lower to the plate, then retract this distance before
starting the arc.
On the Vision CNC, this parameter sets the marking
current in Amperes.
Refer to Section 5 of this manual for the appropriate
values for each of these parameters.
Refer to the machine manual for detailed
instructions on how to change process parameter
settings.
Setup Page 11
Section 5
5 Process Data
The Etcharc Plasma Marker can produce marked
lines in a wide range of widths and depths, ranging
from poor to excellent quality. It can also operate
over a wide range of speeds. The operator must
balance these two factors based on the
requirements for a specific job.
The following pages provide process data for the
six different amperage settings. Each pa ge shows
the setup parameters for that amperage, and a
chart with marking speed range. From the chart,
the operator should select the speed setting based
on the quality of mark that can be accepted.
