Right Display
The right display shows wire feed speed or
amperage. The unit displays and adjusts only
preset wire feed speed at idle. When the unit
is in a welding state, actual wire feed speed is
displayed for the active welding sequence.

The LEDs below the display illuminate to indi-
cate which value is being shown.
•
If the unit is in a welding state that does not
involve feeding wire, the unit displays the
weld sequence wire feed speed. At any time
during welding, the weld sequence wire
feed speed can be adjusted and overrides
the preset wire feed speed display. In other
words, if the Adjust control is activated while
welding, the unit displays and permits ad-
justment of the weld sequence wire feed
speed regardless of the active welding se-
quence.
•
When the unit is displaying amperage, the
Amps LED illuminates. Amperage is only
displayed if the unit is in a welding state and
the amperage is above a minimum value of
25 Amps.
