If such a grounding lead fault occurs, the meter will still be on and will be reading. The trigger circuit will not operate, however . T o release the circuit, press the "GLP Reset" button. See Figure B.1 or B.2 for the location of this button.
DRIVE ROLL INST ALLA TION AND PRESSURE SETTING CHANGING WIRE FEED ROLLS AND GUIDE TUBES FOR TWO-ROLL WIRE FEEDERS T o change drive or idle rolls on a two-roll wire feeder , refer to Figure B.3 and perform the following steps: 1. Loosen idle roll spring pressure screw .
6. Loosen the ingoing guide tube clamping screw . Install the all steel guide tube through the rear brass block. T ighten the locking screw . 7. Replace the large ingoing guide tube into rear brass block. 8. Install the outgoing guide tube with its plastic insert through front brass block.
CHANGING WIRE FEED ROLLS AND GUIDE TUBES FOR 4-ROLL WIRE FEED- ERS T o change drive rolls on a 4-roll wire feeder , refer to Figure B.4 and perform the following steps: 1. Release both quick release levers. 2. Remove clamping collars from both drive shafts.
For Aluminum Wire Each set of rolls should have their pressure set independent of the other . T o do this, release and open the other quick release arm while making each adjustment. Follow the procedure below for each adjustment. 1. With low idle roll pressure, load the feeder so it’s ready for welding.

Do not remove the adapter from the spindle. LOADING A 15 TO 30 LB. SPOOL (12" DIAMETER): (For 8" spools, a K468 spindle adapter must be used.
LOADING 50 AND 60 LB. COILS AND BRAKE ADJUSTMENT (K299 or K303 Wire Reel Stand) 1. T o remove the wire reel from its shaft, grasp the spring loaded knob and pull it out. This straightens the knob so that it seats into the shaft when released. Remove the reel.
ELECTRODE FEEDING 1. T urn the reel until the free end of the electrode is accessible. 2. While tightly holding the electrode, cut off the bent end. Straighten the first 6 inches. 3. Cut off the first inch. Insert the free end through the incoming guide tube.
MAKING A TEST WELD AND ADJUSTING LN-9 RESPONSE AND ST ARTING CHARACTERISTICS ADJUST THE POWER SOURCE DC-250, DC-400, or DC-600* 1. Connect electrode lead to terminal of desired polarity . 2. Set toggle switch to same polarity as the electrode cable connection.
ADJUST THE LN-9 CONTROLS 1. Set the "Electrode Polarity" switch to same polarity as the electrode lead. 2. Connect the "Direct Work Lead" if it is going to be used. 3. Check that "Feed Direction" is set to forward. 4. Set the "T rigger Interlock" switch as desired.
MAKING A WELD 1. Inch the electrode through the gun and cable and then cut the electrode within approximately 3/8" of the end of the contact tip for solid wire and within approximately 3/4" of the extension guide for cored wire. 2. Connect the work cable to the metal to be welded.

SAFETY PRECAUTIONS ELECTRIC SHOCK can kill. • Only qualified personnel should perform this maintenance. • T urn the input supply power OFF at the disconnect switch or fuse box before working on this equipment. • Do not touch electrically hot parts.
GUN AND CABLE MAINTENANCE For instructions on periodic maintenance for the weld- ing gun and cables, refer to the manual for your specif- ic model of welding gun. Also see IM-294.

Return to Master TOC Return to Master TOC Return to Master TOC Return to Master TOC Section E-1 Section E-1 LN-9 Wire Feeder Theory of Operation ..........................................................................................................
POWER INPUT CIRCUITS The 1 15V AC is applied (usually from the welding power source) via the input connector and through the circuit breaker and R1 resistor to the power board, the T2 trig- ger transformer , and the T1 transformer . The 24V AC developed at the T2 trigger transformer is applied to the trigger board.
TRIGGER AND SHUTDOWN CIRCUIT When the gun trigger switch is activated (closed), the trigger board completes the trigger signal path. This energizes the CR1 relay located on the power board. The CR1 relay activates the wire drive motor and the #2 and #4 circuit, which then activates the Lincoln welding power source.
ARC VOL T AGE, WIRE SPEED CONTROL AND METERING The arc voltage, which is sensed at the work piece and motor gear box, is connected through a polarity switch to the voltage board. This actual arc voltage is com- pared to the reference preset voltage that is set by the voltage control.
PRINTED CIRCUIT BOARD FUNCTIONS POWER BOARD The input power (1 15V AC) is applied to the power board, and from that the power board develops the DC field voltage for the wire drive motor . The SCR circuit- ry , used to control the motor armature voltage, is also contained on the power board.
