COMPONENT LOCATION AND ACCESS

Control PC Board:

Remove the left case side. Use a 3/8" Nut Driver or other suitable tool.

Note: The Case side can be removed while roof is in place, as long as the three screws which secure the roof to the case side are removed. The PC Board is mounted on left divider assembly and can be removed with a phillips head screwdriver.

Display PC Board, Arc Starter/Bypass PC Board:

Remove the roof and both case sides. Use a 3/8" Nut Driver or other suitable tool. These PC Boards are located on the inside case front of the machine.

Spark Gap Assembly, High Voltage Transformer:

SPARK GAP ADJUSTMENT

The spark gap is set at the factory to a gap of 0.015 inches (0.4 mm). This setting is adequate for most applications. Where less high frequency is desired, the setting can be reduced to 0.008 inches (0.2 mm).

To adjust the spark, first be sure that the input power to the machine is ‘OFF’ AT THE DISCONNECT SWITCH OR FUSE BOX. The high voltages developed in the high frequency circuit can be lethal. Next, remove the right case side. Use a 3/8" Nut Driver or other suitable tool. Disconnect the two push on wires to the spark gap blocks and pull back the dust shield. Check the spark gap spacing with a feeler gauge. If adjustment is required, pull off one of the two leads going to the alu- minum spark gap blocks. Adjust the gap by loosening the Allen head screw, reset the gap and tightening the screw in the new position. Replace the dust shield and the two leads removed earlier. Reinstall the case side.

FIGURE D.1 SPARK GAP

Remove the right case side. Use a 3/8" Nut Driver or other suitable tool. The high voltage transformer is mounted to the base. The spark gap assembly is locat- ed on the inside case front.

Main Rectifier:

.015 Spark Gap

Remove the roof and both case sides. Next, remove the case back assembly. Use a 3/8" Nut Driver or other suitable tool. The main rectifier is mounted to the main transformer, in front of the cooling fan.
