8. SAVE TO MEMORY KEY: This key is used to save
a newly created welding procedure. The Power
Wave has eight memory locations which can be
used to store all the settings of up to eight welding
procedures. Once stored in a memory location, a
procedure can be recalled for later use with the
RECALL FROM MEMORY key. To save a newly
created welding procedure:
Press the SAVE TO MEMORY key and then
one of the MEMORY LOCATION NUMBER keys.
Keep a record of this number for future reference.
Any previously created welding procedure stored
in that location will be erased.
If you press the SAVE TO MEMORY key but
decide not to save the procedure, you can exit this
function by pressing the DISPLAY RECALL key.
9. MEMORY LOCATION NUMBER KEYS: To view
information about any stored welding procedure,
simply press its MEMORY LOCATION NUMBER
key.
As you hold down the selected key, the procedure
description and gas type of the procedure appear
in the display window. The process type is shown
by the indicating light opposite the appropriate
process symbol.
When you release the selected key, the wire size,
material type and process description appear for a
few seconds.
This function does not display the wire feed speed
and voltage or arc length trim settings. To view
these, you must recall the procedure from memo-
ry with the RECALL FROM MEMORY key.
