When a pair of welding procedures are recalled
from memory, the display window will show the
procedure description, wire feed speed, and the
preset voltage or arc length trim of the LAST pro-
cedure welded with.
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 procedures,
these limits will be active when this overlay is in
place. They cannot be overridden from this over-
lay.
3. THE 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 active procedure, press the DISPLAY
RECALL key. The display window will show the
procedure description and gas type of the active
procedure for as long as the key is held
depressed. When the key is released, the wire
size, material type, and process descriptions dis-
play 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 location is active at any given time.
