1. LCD DISPLAY WINDOW: Power up the machine
with this overlay in place. When the Power Wave is
turned on, the following message appears in the
display window for a few seconds:
LINCOLN ELECTRIC
VERSION X.X
This display is followed by:
OVERLAY ID
NUMBER = 9
2. WIRE FEEDERS MEMORY CHART: The active
welding procedure is determined by the active
wire feeder and its gun switch position. The weld-
ing procedure recall from memory is as follows:
Active Gun Trigger Memory Location
Wire Feeder Position of Procedure
#1 A 1
#1 B 2
#2 A 3
#2 B 4
Pull the trigger on either wire feeder.
Depending on the gun switch position, the corre-
sponding memory location is automatically
recalled. The wire feeders memory chart has no
keys; it is simply a chart.
The display window will show the procedure
description, wire feed speed, and the preset volt-
age or arc length trim of the last active welding
procedure.
With this overlay in place, the wire feed speed and
the preset voltage or arc length trim can be
changed from the wire feeder. The new values
replace the previous values and become a perma-
nent part of the procedure.
If limits have been set on the wire feed speed, volt-
age or arc length trim of the selected procedures,
these limits will be active when this overlay is in
place. They cannot be overridden from this over-
lay.
3. DISPLAY RECALL KEY:To view other information
about the active welding procedure, press the
DISPLAY RECALL key. The display window will
show the procedure description and gas type of
the last active procedure for as long as the key is
held depressed. When the key is released, the wire
size, material type, and process descriptions will
be displayed for a few seconds.
4. HIGH TEMPERATURE LIGHT: The high tempera-
ture light comes on when the internal machine
temperature exceeds the allowed limit. Output is
disabled until the machine cools down and the
high temperature light goes out.
5. MEMORY LIGHTS: A memory light is on when its
corresponding memory is selected. This tells you
what memory location is active at any given time.

The Dual Wire Feeders, Dual Procedures Overlay is used when the Power Wave is equipped with two wire feed-

can be automatically recalled and used. See Figure B.7.
