12. TOGGLE KEY

: When first pressed, this key
turns ON the TOGGLE MODE and recalls the weld
setup in memory 4. Pressing the key again switch-
es to the weld setup in memory location 5. Each
time the key is pressed, it alternates between the
two memory locations. When the TOGGLE key is
pressed, the LED screen displays the memory
number the current setup was recalled from, indi-
cates automatic (AUTO:) or manual (MAN:) mode,
displays wire gauge (Auto Mode), wire feed speed,
and arc voltage. The cursor underlines the mem-
ory number currently selected.
If in AUTO mode, an up or down arrow shows
whether the arc voltage has been adjusted above
or below the recommended level. Spot or Stitch
timer status is displayed in the lower left-hand cor-
ner if either timer is active.
The gun thumb switch functions as a Toggle key in
Toggle mode. Pushing the gun thumb switch for-
ward (toward the tip) selects the setup in memory
5. Pulling gun thumb switch back selects the setup
in memory 4. The gun thumb switch also functions
with the trigger closed for "on the fly" changes dur-
ing a weld. See Figure B.5.
To turn the toggle mode off, press the AUTO, MANU-
AL, or any MEMORY Number key.

are not automatically saved when power is removed,
