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
LN-25™ PIPE
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.
To change the Run-in setting:
Rotate the WFS knob to
the left to turn Run-In OFF.
Rotate the WFS knob to
the right to turn Run-In
ON.
Then rotate the WFS knob
to the 12 o'clock position.
Press the set-up button
again to enter the WFS cal-
ibration menu.

WFS CALIBRATION WITH DIGITAL
METERS
To calibrate the wire feed speed, before entering the
set-up menu. When first entering WFS Calibration, the
calibration factor displayed is based upon the position
of the knob and does not reflect the actual calibration
factor stored in memory.
Set the display to the desired wire feed speed (exam-
ple: 400 inches per minute).
Measure the actual wire feed speed (example: 405
inches per minute).
While in the set-up menu, adjust the calibration factor
as follows:
