A-2 INST ALLA TION LN-35 A-2 ELECTRIC SHOCK can kill. • Do not operate with covers removed. • Turn off power source before installing or servicing. • Do not touch electrically hot parts. • Turn the input power to the welding power source off at the fuse box before working in the terminal strip.
A-3 INST ALLA TION LN-35 A-3 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.
A-4 INST ALLA TION LN-35 A-4 WELD CABLE CONNECTION The size of the electrode cable and work cable must be sufficient for the maximum weld current and total cable length to be used.
B-1 OPERA TION LN-35 B-1 ELECTRIC SHOCK can kill. • Do not touch electrically live part or electrode with skin or wet clothing. • Insulate yourself from work and ground. • Always wear dry insulat- ing gloves. ARC RAYS can burn. • Wear eye, ear and body protection.
B-2 OPERA TION B-2 LN-35 TO MOUNT A 50 OR 60 LB COIL: 1. To remove the wire reel from its shaft. 2. Lay the reel flat on the floor. Loosen the spinner nut and remove the cover plate. See Figure B.1. 3 . Place the coil of electrode on the reel so it unwinds as the reel rotates clockwise.
B-3 OPERA TION B-3 e. Press the gun trigger and push the electrode until it just enters the drive roll. When inching with gun trigger, the electrode and drive mechanism are always “hot” to work and ground. --------------------------------------------------------------------- f.
B-4 OPERA TION B-4 LN-35 PRESETTING WIRE FEED SPEED The LN-35 permits accurate presetting of the desired wire feed speed, before welding, in both CV and CC wire feed modes. SETTING CONSTANT WIRE FEED SPEED ( C V MODE) a. Set Wire Feed Mode switch to CV position.
B-5 OPERA TION B-5 MAKING A WELD SETUP a. Connect work cable to metal to be welded. Work cable must make good electrical contact to the work. The work must also be grounded as stated in “Arc Welding Safety Precautions.
B-6 OPERA TION B-6 a . Cut the electrode within approximately 3/8”(9.5mm) of the end of the contact tip for solid wire and within approximately 3/4”(19.1mm) of the extension guide for cored wire. b. Position electrode over joint. End of electrode should be slightly off the work.
B-7 OPERA TION B-7 CC (formerly VV) power sources, on the other hand, permit the arc voltage to decrease with increases in welding current. The output characteristics of these power sources can range .
D-1 MAINTENANCE D-1 LN-35 SAFETY PRECAUTIONS Have qualified personnel do the maintenance work. Turn the engine off before working inside the machine. In some cases, it may be necessary to remove safety guards to perform required maintenance. Remove guards only when necessary and replace them when the maintenance requiring their removal is complete.
D-2 MAINTENANCE D-2 ADJUSTING SPEED SENSOR MODULE The LN-35 Speed Sensor Module is a three lead Hall Effect switch device encased in an externally threaded housing which is screwed into a mounting plate on the motor side of the wire drive gearbox.
