c. Place “Set to Same Polarity As Electrode Cable Connection” switch at appropriate position.

d. Place power source toggle switch in “Output Control at DC(CV) - 400” position, unless a remote control is connected to 75, 76 and 77 on the power source terminal strip.

e. If power source has a mode switch, set switch to Constant Voltage Innershield. Initially set the output control on “6”.

DC-600

a. Connect a jumper from 2 to 4 on the power source terminal strip so the output will be energized when the DC-600 is turned on. (For DC-600 below Code 8200, also jumper N to S.)

b. Connect the electrode cable to the output terminal of polarity required by electrode . Connect work lead to other output terminal.

c. Place “Set to Same Polarity As Electrode Cable Connection” switch at appropriate position.

d. Place power source toggle switch in “Output Control at DC-600” position, unless a remote control is connected to 75, 76 and 77 on the DC- 600 terminal strip.

e. Set mode switch to Constant Voltage Innershield. Initially set output control on “4”.

R3S-325

a. Connect a jumper from 4 to 32 on the power source terminal strip so that the output will be energized when the R3S-325 is turned on.

b . Connect the electrode cable to the output terminal of polarity required by electrode . Connect work lead to other output terminal.

c. Set power source per its instruction manual.

NOTE: Use of the optional Line Voltage Compensator available for the R3S - 325 is recommended if input line voltage variation exceeds ±3%.

SAM-400, —650

a. Connect a jumper from 2 to C4 on the power source terminal strip so the output will be energized when the SAM power source is on.

b. Connect work lead to WORK stud. Connect electrode to AUTO EQUIPMENT stud. Connect SAM-650 “Tap” lead to the Innershield stud LN-25desired.

c. Set ELECTRODE POLARITY switch to constant voltage polarity required by electrode.

d. Set toggle switch to “Constant Voltage” and set the Constant Voltage Control on welder and the portable field control on #5 for initial start.

SA-200, —250 OR SAE-300, —400 (WITH

CV ADAPTER)

a. For electrode negative welding, connect the electrode lead from the LN-25 to the output terminal on the CV Adapter, and the work lead to the power source output terminal labeled “POSITIVE”. For electrode positive welding, interchange the above lead connections so the LN-25 electrode lead is then connected to the positive power source terminal.

b. Place both switches on the CV Adapter to the CV INNERSHIELD position and make appropriate power source settings per the CV Adapter instruc- tions provided for the power source being used.

c. The output voltage is set with the voltage control on the CV Adapter.

NOTE: Refer to the Instruction Manual provided with the machine for details on connection and operation of the LN-25 with the power source.

INVERTEC, CV300 AND OTHER NEWER LINCOLN POWER SOURCES

Refer to the instruction manual provided with the power source for details on connection and operation of the LN-25 with these newer machines.

GUN CABLE CONNECTION TO FEEDER

Lay the cable out straight. Insert the connector on the welding conductor cable into the brass conductor block on the front of the wire drive unit. Make sure it is all the way in and tighten the hand wheel clamp. Keep this connection clean and bright. Connect the control cable polarized amphenol plug into the mating 5-cavity receptacle on the front panel of the wire feeder case.

FOR GMA GUN AND CABLES:

Requires installation of K430-1 Gas Solenoid Kit (factory installed on K446 and K449 models).

See K430-1 Gas Solenoid Kit Section (in Accessories Section) for gas solenoid operation and gas supply connection.
