CONSUMABLE RELATED SAFETY LED TROUBLESHOOTING

A. If the Safety LED is LIT AND STEADY, perform the following:

1.If the reset button (when pressed) does not turn the Safety LED off, the reset button or associated wiring may be faulty. See the wiring diagram.

Press the reset button. If the torch and consumables are properly installed, the Safety LED should turn off.

2.If this has occurred numerous times, clean consumables with a piece of fine emery cloth to remove any oxide buildup on the tip of the electrode, or try replacing the electrode and nozzle.

Try to recount the number of times that the Safety LED has come on lit and steady with this particular set of consumables.

If problems persist after completing steps 1 and 2,

contact your local Lincoln Authorized Field Service Facility.

B. If the Safety LED is FLASHING, perform the following:

1.Check the condition of the electrode. The maximum wear depth in the center of the electrode tip is approxi- mately .060" relative to the surrounding tip. A green and erratic arc will indicate definite electrode failure as explained in the "Consumable Life" section of this manual.

Replace both electrode and nozzle if electrode is excessively worn. Otherwise, use a piece of fine emery cloth to remove any oxide buildup on the tip of the electrode. Even if consumables appear to be in good working order, it is possible that they are the cause of the problem. Try replacing.

2.Check the conditions of the inside of the nozzle. Make sure that both the electrode and nozzle are not dirty, oily, or corroded.

If debris has collected, rub the electrode on the inside bottom of the nozzle to remove any oxide layer that may have built up. If problems persist, try replacing consumables.

3.Remove consumables from torch and check inside of torch head for contamination. Check incoming airflow for contaminants.

If torch head is contaminated, take a dry cotton swab and clean out the pollutants. If needed, replace air filter and check/change air supply. For more information, refer to the "Gas Input Connections" section in the manu- al.

4.Make sure there is a Lincoln PCT 80 torch connected properly to the Pro-Cut 55 and that the consumables are properly installed. Make sure the shield cup is hand tight. Do not use pliers or over-tighten.

After verifying that the torch and consumables are properly set in place.

NOTE: Make sure that consumables are Lincoln Electric brand consumable parts. These parts are patented and using any other replacement consumables may cause damage to the torch or reduce cut quality. Also be sure to check that the nozzle is the correct part number (as identified on the top and side of the nozzle) for the Pro-Cut being used.

If problems still persists after completing steps 1 thru 4,

contact your local Lincoln Authorized Field Service Facility.
