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.

COLD FEED	COLD FEED	Cold Feed Keys - energize
FORWARD	REVERSE
		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	Gas Purge key - energizes the gas
	solenoid valve but not the wire feeder or
	power source.
