4. AUTO KEY:

Press for automatic welding set up
of recommended Wire Speed and Arc Voltage
based on Metal Thickness selected.
ARROW KEY OPERATION WHEN USED WITH
AUTO KEY:
See Table B.1.
Left Arrow Keys: Press to change the metal thickness
displayed. Press the UP ( )arrow key to increase
metal thickness. Press the DOWN ( ) arrow key to
decrease the metal thickness. Increasing or decreas-
ing metal thickness automatically increases or
decreases both wire feed speed (IPM) and arc voltage
(VOLTS) simultaneously.
instruction label on the inside of SP-250 door for avail-
able sizes.
Center Arrow Keys: Press to change wire feed speed
setting. Press the UP ( ) arrow key to increase the
wire feed speed setting displayed. Press the DOWN
( ) arrow key to decrease the wire feed speed setting
displayed. Increasing or decreasing the wire feed
speed simultaneously causes an increase or decrease
in the arc voltage and can change the metal thickness
setting.
Right Arrow Keys: Press to change arc voltage set-
ting. Press the UP ( ) arrow key to increase the arc
voltage setting displayed. Press the DOWN ( ) arrow
key to decrease arc voltage setting displayed. An up
arrow indicator appears below the V in VOLTS if the
arc voltage has been set higher than the recommend-
ed value. A down arrow indicator appears below the V
in VOLTS if the arc voltage is below the recommended
value. No arrow indicates that you are set to the rec-
ommended value.
Pressing the AUTO key again resets the wire feed
speed and arc voltage settings to the recommended
values for the metal thickness displayed. (NOTE: If
the spot or stitch timers are on, metal thickness is not
displayed and, therefore, the reset function does not
work.)

5. MANUAL KEY:

Press to set wire feed speed
and arc voltage for manual procedure setup. The
manual screen displays wire feed speed, arc volt-
age, and a cursor that indicates when the wire feed
speed or arc voltage is being controlled by the
thumb switch on the SP-250 gun.

IDEALARC SP-250
ARROW KEY OPERATION WHEN USED WITH
MANUAL KEY:
See Table B.1.
Left arrow keys: Do not function in Manual mode.
Center arrow keys: Press the UP ( ) arrow key to
increase wire feed speed. Press the DOWN ( ) arrow
key to decrease wire feed speed.
Right arrow key: Press the UP (
increase arc voltage. Press the DOWN ( ) arrow key
to decrease arc voltage.
NOTE: If the spot or stitch timers are ON, it will be indi-
cated in the bottom left corner of the display. See

Timers are ON.
6. SAVE KEY: Press to save the current set up. The
process, procedure, and timer functions (if used)
are saved to one of five memory locations by
pressing one of the five memory keys. When the
Save key is pressed, a prompting message
instructing the operator to "PRESS MEMORY 1-5
TO SAVE SETUP" is displayed. See Figure B. 3
for sample SAVE sequence.
remains displayed until a memory number key is
selected or one of the other keys, such as Auto,
Manual, or Process, is pressed. If a memory num-
ber key is selected, a message will be displayed
for 2.5 seconds that confirms that the setup was
saved to that memory number.
The six arrow keys perform no function when saving a
setup.
NOTE: When a setup is saved to a memory location,
the previous contents of that memory is lost because it
is replaced by the present setup.
