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 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.
