WARNING

Have qualified personnel do the maintenance work. Always use the greatest care when working near moving parts.

Do not put your hands near the cooling blower fan. If a problem cannot be corrected by following the instructions, take the machine to the nearest Lincoln Field Service Shop.

-----------------------------------------------------------------------

ELECTRIC SHOCK can kill.

•Do not touch electrically live parts or electrode with skin or wet clothing.

•Insulate yourself from work and ground

•Always wear dry insulating gloves.

------------------------------------------------------------------------

EXPLODING PARTS can cause injury.

• Failed parts can explode or cause other parts to explode when power is applied.

•Always wear a face shield and long sleeves when ser- vicing.

INPUT FILTER CAPACITOR

DISCHARGE PROCEDURE

1.Remove the input power to the V350-PRO.

2.Using the 5/16” wrench remove the screws from the case wraparound cover.

3.Be careful not to make contact with the capacitor terminals located at the top and bottom of the switch board.

4.Obtain a high resistance and high wattage resis- tor (25-1000 ohms and 25 watts minimum). This resistor is not with the machine. NEVER USE A SHORTING STRAP FOR THIS PROCEDURE.

5.Locate the eight capacitor terminals shown in fig- ure D.1.

6.Using electrically insulated gloves and pliers, hold the body of the resistor with the pliers and connect the resistor leads across the two capacitor termi- nals. Hold the resistor in place for 10 seconds.

DO NOT TOUCH CAPACITOR TERMINALS WITH YOUR BARE HANDS.

7.Repeat the discharge procedure for the other three capacitors.

8.Check the voltage across the terminals of all capacitors with a DC voltmeter. Polarity of the capacitor terminals is marked on the PC board above the terminals. Voltage should be zero. If any voltage remains, repeat this capacitor dis- charge procedure.

1.Every 6 months or so the machine should be cleaned with a low pressure airstream. Keeping the machine clean will result in cooler operation and higher reliability. Be sure to clean these areas:

•All printed circuit boards

•Power switch

•Main transformer

•Input rectifier

•Auxiliary Transformer

•Reconnect Switch Area

2.Examine the sheet metal case for dents or breakage. Repair the case as required. Keep the case in good con- dition to insure that high voltage parts are protected and correct spacings are maintained. All external sheet metal screws must be in place to insure case strength and elec- trical ground continuity.
