Wire Feed Speed Units
To change the wire feed speed units:
Rotate the WFS knob to
the
left
to
use
“inches/minute” for the
wire feed speed units.
Rotate the WFS knob to
the
right
to
use
“meters/minute” for the
wire feed speed units.
Then rotate the WFS knob
to the 12 o’clock position.
Press the set-up button again to enter the Run-In
menu.
RUN-IN
“Run-in” refers to the wire feed speed during the time
from when the trigger is pulled to when an arc is
struck.
When Run-in is “ON”, the wire feed speed is reduced
until an arc is struck. Factory setting is Run-In “OFF”.
Model
Run-in Wire Feed Speed
Extra Torque Models
25 in/min
Standard Speed Models
50 in/min
When Run-in is “OFF”, the wire feed speed is the
same as the welding wire feed speed. Turn Run-In
“OFF” for fast, crisp starts, especially when running
with .035 or .045 (0.9 or 1.2mm) solid steel wires at
high wire feed speeds.
