LN-25 A-2 A-2 INST ALLA TION 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.
LN-25 A-3 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. SA-200, —250 OR SAE-300, —400 (WITH CV ADAPTER) a.
LN-25 A-4 A-4 INST ALLA TION Install the barbed fitting and union nut to the 5 8 -18 female inert gas fitting on the front panel of the LN-25 case. Connect the 3 16 ” I.D. gas hose from the gun cable to the barbed fitting. When the gun is to be removed, this fitting can be easily detached by loosening the union nut.
LN-25 B-1 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 insulating gloves. ARC RAYS can burn. • Wear eye, ear and body protec- tion.
LN-25 B-2 B-2 OPERA TION VOLTMETER (Factory installed on model Codes above 9218) The 40V DC analog voltmeter is mounted to the front control panel of the LN-25 and is connected to read the arc voltage between the LN-25 electrode cable connection and the work clip lead.
LN-25 B-3 B-3 The volts marks around the HI range calibrated dial indicate the minimum arc volts required to obtain the indicated HI range wire feed speeds. For example; if wire speed is set to 400 in/min., a welding procedure arc voltage of at least 17V would be required to obtain the 400 in/min.
LN-25 B-4 B-4 OPERA TION g. To remove Readi-Reel from Adapter, depress re- taining spring tab with thumb while pulling the Readi-Reel cage from the molded adapter with both hands. It is not necessary to remove adapter from spindle. h. Load wire into wire drive per Loading Wire Drive Section.
LN-25 B-5 B-5 LOADING WIRE DRIVE a. Turn the reel or spool until the free end of the electrode is accessible. b. While tightly holding the electrode, cut off the bent end and straighten the first six inches.
LN-25 B-6 B-6 OPERA TION 3. If the only result is drive roll slippage, shut off the power source, then loosen the gun cable clamping screw in the gearbox conductor block and pull the gun cable forward about six inches. There should be a slight waviness in the exposed wire.
