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 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. Check the spark gap spacing with a feeler gauge. If adjustment is required, pull off one of the two leads going to the aluminum spark gap blocks. Adjust the gap by loosening the Allen head screw, reset the gap and tightening the screw in the new position. Reattach the lead removed earlier, and reinstall the case side.
