display window for a few seconds:

2. MEMORY RECALL NUMBERS: Select the mem-
ory location of the desired welding procedure by

When a welding procedure is recalled from mem-
ory, the display window will show the procedure
description, wire feed speed, and arc length trim
or preset voltage.
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 will
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 procedure,
these limits will be active when this overlay is in
place. They cannot be overridden from this over-
lay.
3. PROGRAM LIST: The PROGRAM LIST block in
the center of this overlay provides a convenient
place to record a brief description of each welding
procedure stored in memory. A “Dry Erase” mark-
er should be used for this purpose.
4. DISPLAY RECALL KEY: To view other information
about the selected procedure, press the DISPLAY
RECALL key. The display window will show the
procedure description and gas type of the se-
lected procedure for as long as the key is held
depressed. When the key is released, material
type, wire size, and process descriptions will be
displayed for a few seconds.
5. 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.
6. MEMORY LIGHTS: A memory light is on when its
corresponding memory is selected. This tells you
what memory is active at any given time.
