Timer/Crater Select - key enables
operator to choose crater speed, spot
or gas timers as indicated by the
appropriate light. Pressing key causes
lights to sequence (left to right, top to
bottom) starting from the current
indicated position. Any parameter not
available in the mode selected is
skipped over. If a function is being
displayed when the Timer/Crater Select
key is pressed, then the light of the last
parameter selected before the function
was chosen will come on and become
the starting point for the sequencing.
Top Left Light
- indicates preflow time
is being displayed in seconds. This is
the time the shielding gas flows before
the wire feed and power source are
activated.
Top Right Light
- indicates postflow
time is being displayed in seconds.
This is the time the shielding gas flows
after the wire feed and power source
are deactivated.
Middle Light
- indicates that crater feed
speed is being displayed. Crater speed
is only available when 4-step trigger
with crater fill is selected. It is activated
by Step 3 and deactivated by Step 4 of
the 4-step sequence. (See 4-step
trigger mode selection section).
Bottom Light
- indicates spot on time is
being displayed in seconds.
NOTE: if unit is not
in spot mode then
this light will be skipped over in the
selection sequence.
Increase Arrow - key increases the
setting of the parameter selected to be
displayed, except Wire Feed Speed and
Volts/Trim which are controlled by the
encoder knobs.
Decrease Arrow - key decreases the
setting of the parameter selected to be
displayed, except Wire Feed Speed and
Volts/Trim which are controlled by the
encoder knobs.
Arrow key adjustments use the
“Accelerating Digit” method for setting
changes, where holding the arrow key
causes setting change rate to
accelerate from slow to fast. Releasing
arrow key resets to slow setting
change.
Acceleration Selection
Pressing both the Gas Purge key
and then function select key at the
same time causes the acceleration
setting to be displayed. The display
will indicate “A-X” where X will be
a number from 1 through 5 with 5
being the fastest acceleration. This
number can be adjusted using the
arrow keys. To exit this function,
press both these keys again or
press any other key except the
arrow keys.
Selection of English or
Metric Speed Display Units
Pressing both the Gas Purge key
and then timer select key at the
same time causes the speed
display units to toggle between IPM
(no decimal point displayed) and
m/m (a decimal point displayed). If
the speed display units were IPM,
then they will change to m/m. If the
speed display units were m/m, then
they will change to IPM. If the
display is showing the volts/trim or
one of the timers when the keys are
pressed, the display will be
changed to weld speed to indicate
the selected speed display units.
Run-In Selection
Pressing both
the Gas Purge and Cold
Feed keys at the same time causes
Run-In function to toggle on or off, as
indicated by the Run-In indicator light
turning on or remaining off in the
function select sequence.
As shipped, the Run-In function is off
with a fixed setting of min. rated speed.
Therefore, the Run-In indicator light will
not sequence with the function select
key, but the fixed setting will still be
used for actual Run-In speed.
Activation of adjustable Run-In speed
using the above dual key press, will
permit Run-In speed to be adjusted with
the arrow keys and the Run-In indicator
light will return to function key
sequence. Re-pressing the above dual
key again removes the Run-In light from
the function key sequence, but replaces
the fixed Run-In speed with the
adjusted Run-in speed setting, until
readjusted.
