3. WIRE FEED SPEED KNOB - The Wire Feed Speed
knob is a 3-3/4 turn potentiometer that adjusts of
the rate of feeding electrode. The wire feed speed
range is 50 - 700 inches/min (1.3 - 17.8 m/min)
4. TRIGGER CONNECTOR-5 Pin Receptacle is used
to activate the Magnum Gun Switch.
5. CONNECTOR BUSHING-This connection is for
welding conductor cable assembly.
6. WORK CLIP LEAD-This lead must be connected
directly to the work using the spring clip.
7. ON / OFF SWITCH-For codes 11033 and above:
The ON / OFF Switch turns power on and off to the
wire feeder.
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 Magnum 400 Dual Procedure Gun
Equivalent.

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 nega-
tive welding procedures. While welding, an LED
will illuminate below the voltage display. After weld-
ing, the average voltage will continue to be shown
for 5 seconds 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.
