ACROSS THE ARC MODEL
1. WIRE FEED SPEED DISPLAY-The Wire Feed
Speed display shows the rate the LN-15 will feed
electrode during welding. The default WFS units for
domestic models are inches/minute and can be
changed to meters/minute through the configuration
menu. The default WFS units for the European
models are m/min. The wire feed speed is calibrat-
ed to within ±2%.
-
2. VOLTAGE DISPLAY The voltage display shows the
average arc voltage during welding. A minus sign "-
" appears when welding with electrode negative
welding procedures. While welding, an LED will illu-
minate below the voltage display. After welding, the
average voltage will continue to be shown for 5 sec-
onds after the end and the LED will flash. of the
weld. When not welding, the display shows "- - - ".
The voltage is calibrated to ±2% over a range of 10
to 45 volts.
The voltage display is not a "preset" voltage.
Refer to the examples from Figure B.1a.

83% PROCEDURE
The LN-15 supports a special "dual procedure" mode.
When activated, the wire feed speed is reduced to 83%
of the set value, but no less than 50 inches/minute
(1.27 m/min). The 83% procedure is most commonly
used during pipe and out of position welding. Requires
