Keypad and Display Description

Keypad - Seven key, membrane type with "snap" tac-
tile feel and embossed domes. Long life design.
Spatter resistant surface.

Displays - Two digital LED displays with .56" (14.2
mm) character height. Top (3-1/2 digit) displays
Preset and Actual (while welding) arc voltage in volts
with (+) or (-) polarity indicators, and also displays all
timers in seconds. Bottom (4 digit) displays preset
wire feed speed in IPM, or m/m, and acceleration
selection.

Indicator Lights - Extra bright red LEDs for viewing
at almost any angle. Always indicate the feeder and
procedure selected, trigger mode being used and
function or timer being displayed.

Rotating Encoders - Knob controls increase or
decrease settings of volts and wire feed speed. (ini-
tially factory set to minimum) Alternately, the top
encoder adjusts timer settings and bottom selects
acceleration settings when selected for these parame-
ters to be displayed.

Power-Down Save

Power to the LN-10 is supplied and controlled from
the power source. The LN-10 automatically senses
the loss of power when the power source is turned off.
Dual procedure settings, including; trigger mode, cold
feed speed, Run-in and weld speed and voltage,
timers and acceleration are automatically saved for
each feeder when power is removed. This feature
does not require batteries and when power is restored
it will automatically return all settings to the state they
were in when power was removed. The operator may
overwrite any or all of these settings following power
up recall.

Operation Keys

Procedure Lights - Indicate which
procedure (A or B) is selected for the
selected feeder. The Procedure select
key selects A or B, or if REMOTE Light
is selected, the procedure selection
light is controlled by connection of an
optional Dual Procedure gun switch
(K683-1, -3) or Dual Procedure
Remote Control (K1449-1).

Cold Feed Keys - energize
the wire feeder but not the
power source or gas sole-
noid valve. Cold Feed
Forward speed is factory

set at 200 IPM, but is adjustable with WFS encoder
knob and displayed on WFS display (with ”Cld” shown
on the Voltage display) only while pressing Cold Feed
Forward, and the last speed set is stored in memory
for the next cold feeding, unless changed in Cold
Feed trigger mode (see following section). Cold Feed
Reverse retracts wire at a fixed 80 IPM speed which is
not adjustable.

Gas Purge key - energizes the gas
solenoid valve but not the wire feeder or
power source.
