OPERATION
B-5
Range Select key - enables operator to
choose which weld parameter to set the maxi-
mum or minimum range. Pressing the key
causes the range mode lights to sequence (top
to bottom) starting from the current indicated
selection. The range settings can be set inde-
pendently for each procedure.
Top Light - PEAK MAX - Indicates that the
maximum peak current setting is being dis-
played on the top LED display. This para-
meter is settable from 17 to 464 amps.
Second Light - PEAK MIN - Indicates that
the minimum peak current setting is being
displayed on the top LED display. This
parameter is settable from 17 to 464 amps.
Third Light - BACKGROUND MAX - Indicates that the maximum
background current setting is being displayed on the top LED
display. This parameter is settable from 6 to 153 amps.
Fourth Light - BACKGROUND MIN - Indicates that the minimum
background current setting is being displayed on the top LED
display. This parameter is settable from 6 to 153 amps.
Fifth Light - WFS MAX - Indicates that the maximum wire feed
setting is being displayed on the bottom LED display. This para-
meter is settable for the entire wire feed speed range of the cur-
rent wire feed head.
Bottom Light - WFS MIN - Indicates that the minimum wire feed
setting is being displayed on the bottom LED display. This para-
meter is settable for the entire wire feed speed range of the cur-
rent wire feed head.
Acceleration Selection
To provide optimum starting of various processes and proce-
dures, the wire feed acceleration of the STT-10 can be set to
five levels; 1 thru 5, for each procedure. 1 is the slowest accel-
eration and 5 is the fastest. (Factory set to 4.)
To change acceleration hold the Gas Purge
Key closed, then press the Range key. The top
display shows “Acc” indicating acceleration set-
ting, 1 thru 5, is displayed on the bottom
(Speed) display. Use the speed encoder knob
to change setting from 1 thru 5.
To exit this function, and enter the acceleration
setting into the procedure memory, press both
keys again or close the trigger.
Security Mode
Security mode is provided to capture and prevent changing of
procedure settings. Security mode is activated, or deactivated
by setting S1 DIP switch located inside the STT-10 Control Box.
Security mode is used to capture control, acceleration, and
range selections and settings, then to disable these selections
until security mode is deactivated. Encoder knob setting
changes of cold feed, weld speed, peak current, and back-
ground current are not disabled.
Security mode is activated, or deactivated, by shutting off the
input power to the STT-10 with all Range and Control settings
as desired for both procedures. Then setting S1 DIP switch 6
inside the STT-10 Control Box ON or OFF and restoring input
power (See “Security Mode Selection” in this section).
When activated, the Range and Control selections no longer
light, but function with the captured settings. All other keys and
encoder knob controls function normally.
