SAFETY PRECAUTIONS

WARNING

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.

•Only qualified personnel should install, use or service this equipment.

ROUTINE MAINTENANCE

Routine maintenance consists of periodically blowing out the machine, using a low pressure airstream, to remove accumulated dust and dirt from inside the feeder.

PERIODIC MAINTENANCE

•Replace the drive rolls and inner wire guide when they are worn.

•Replace the pig tail if the insulation is cut, abraded or damaged.

CALIBRATION SPECIFICATION

All calibration is factory set on the LN™-15.

To verify the wire feed speed:

•Assemble a .045 (1.2mm) drive roll kit into the LN™-15.

•Load a spool of .045 (1.2mm) electrode and thread the electrode through the wire drive.

•Adjust the wire feed speed to 300 in/min (7.62m/min).

•Press the COLD FEED switch and measure the actual wire feed speed with a calibrated wire feed speed tachometer.

•The measured wire feed speed should be within 2% of the set value.

To verify the voltage display:

•Set the welding power source and LN™-15 to a CV procedure that gives steady "spray" transfer in the arc.

•While a weld is being made, measure the voltage from the feed plate to work.

•The displayed voltage on the LN™-15 should be within 2% of the measured value.
