SAFETY PRECAUTIONS

WARNING
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts such
as output terminals or internal wiring.
• Unless using cold feed feature when inch-
ing with gun trigger, electrode and drive mech-
anism are "hot" to work and ground and could
remain energized several seconds after the
gun trigger is released.
• Turn OFF input power at welding power
source before Control switch setup or
changing drive roll and/or guide tubes.
• Welding power source must be connected
to system ground per the National
Electrical Code or any applicable local
codes.
• Only qualified personnel should
operate this Equipment.
Observe all additional Safety Guidelines detailed
throughout this manual.

DUTY CYCLE

The LN-10 models are rated at 60% duty cycle * for a
maximum current of 600 amps.
* Based on a 10 minute time period (6 minutes on, and 4 minutes off).
LN-10 CONTROL DIP SWITCH
SETUP
Initial set up of the LN-10 control for the system com-
ponents being used and for general operator prefer-
ences is done using a pair of 8-pole DIP switches
located inside the LN-10 control box.
"Other: Power Source Independent" power
source selection dip switch setting:
The LN-10 is designed to work with the following
Lincoln Electric power sources: CV250, CV300-I,
CV300, CV400-I, CV400, CV500-I, CV655, DC250,
DC400, DC600, DC650 PRO, DC1000, Pulse Power
500 (non-pulse CV modes only), the V300 PRO,
V350 PRO, and the DC655.
To use the LN-10 with other power sources, the
"Other: Power Source Independent" power source
selection dip switch setting (S1 switches 1-4 in the
OFF position) may be used. All LN-10 features oper-
ate as described elsewhere in this manual except for
the following differences:

OPERATION

1. Instead of displaying a preset value in volts, the top
display will show a number from "0.00" to "10.00" in
increments of 0.02. The number can be used for
setting run-in "voltage" as well as "weld preset volt-
age". When the trigger is closed or while welding,
the top display will display actual arc voltage.
The voltage displayed while welding can be used to
determine the arc voltage to be expected for a given
number setting. Actual arc voltage display will still
flash for 5 seconds after a weld has been completed.
2. If a loss of arc voltage occurs, wire will NOT stop
feeding. The Loss of Voltage Sense Shutdown fea-
ture is disabled to permit the use of the LN-10 with
power source connections that do not connect the
work voltage back to the LN-10 through the input
power cable. The actual weld voltage while welding
will NOT be shown on the top display if the work
voltage is not available to the LN-10 through the
input power cable.
Setup DIP Switch Access
1) Shut off the input power to the LN-10 control by
turning off the power at the welding power source it
is connected to.
Have qualified personnel do the set up and
maintenance work. Turn the input power off at
the power source before working inside the wire
feeder.
-----------------------------------------------------------------------
2) Remove the two screws on the top of the LN-10
control box door and swing the door down to open.
3) Locate the two 8-pole DIP switches, near the top
left corner of the LN-10 Control P.C. board, labeled
S1 and S2.
NOTE: Switch settings are only programmed during
input power-up restoration.
