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:

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.

WARNING

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.
