POWER-UP SEQUENCE
All of the LEDʼs will briefly illuminate during power-up.
If the gun trigger is activated during power up, the
feeder will not operate until the gun trigger is released.
WIRE FEED SPEED/AMPERAGE DISPLAY
Idle
The left display shows the preset wire feed speed.
The right display shows OCV. The wire feed speed
LED is lit.
Welding
The value in the left display will be either amps or
actual wire feed speed, depending upon the selection
chosen in the set-up menu. The corresponding LED
below the display will light. Note that actual WFS may
not match preset WFS, if welding at low voltages with
high wire feed speeds. The right display shows the arc
voltage. If the wire feeder is connected for electrode
negative welding, then the voltage display shows a
minus sign.
After Welding
The display continues to hold the value of the amper-
age or WFS and arc voltage for five seconds after
welding stops. The amperage or WFS and voltage
displays flash.
