AUXILIAR Y EQUIPMENT CONT ACTS The power for 1 15 volt AC auxiliary equipment can be obtained from the terminals inside the LN-9 GMA con- trol box. The contacts are “hot” whenever the trigger is pressed or the unit is welding. The current draw of this circuit must not exceed 1/4 ampere.
A TT ACHING THE WIRE REEL ST ANDS The mounting hardware for mounting the stands is included with the LN-9 GMA. Screws and washers are inserted in their respective mounting holes. T o con- nect: 1. Remove the three 3/8 in. hex head bolts from the back of the wire feed unit.
UNIVERSAL WIRE REEL ST AND (K1524-1) Includes a 2" (51mm) O.D. Spindle with adjustable brake and two locations for mounting the spindle to allow for the mounting of 50 - 60lb, 10 - 30 lb, 13 - 14lb, and 8" O.D. coils with proper spindle adapters.
WIRE FEEDER ACCESSORIES BURNBACK TIMER KIT (K419) Provides a precise control of the electrode burnback at the end of the weld. Prevents crater sticking and provides proper stickout for starting the next weld. Recommended especially when welding with small (0.

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. PROPER SPEED SENSOR MODULE MOUNTING The LN-9 GMA Speed Sensor Module is a three lead Hall-Ef fect switch device encased in an externally threaded housing.
The following Figures D.2 and D.3 should serve as a guide to determine if a particular gun or switch can be connected to the LN-9 GMA and LN-9F GMA. “A” Diameter Hole to be Concentric to Wire Size .749/.747 (19.0/18.9) in. (mm) Diameter Within .008 (.
Return to Master TOC Return to Master TOC Return to Master TOC Return to Master TOC Section E-1 Section E-1 LN-9 GMA 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 variable DC armature voltage for the permanent mag- net wire drive motor . The SCR circuitry , used to con- trol the motor armature voltage, is also contained on the power board.
