REPAIR.
There are no user serviceable parts inside the unit. In the event that
the unit requires service, send it back to the factory. However, parts are available
separately, so an
experienced electronics technician
can make repairs. The
following troubleshooting guide is furnished:
Disassembly Instructions:
With the power removed from the unit, remove the electrode tip, and the remove
the 10-32 hex nut by using the special 5/16 in. nut driver, P/N 049-0025-1. Then
remove the top half (smooth cone portion) of the plastic housing by turning it
counterclockwise.
Turn the black adjusting knob counterclockwise and remove it by holding the
brass adjusting screw with the special 3/16-in. wrench, P/N 049-0026-1 and
turning the knob counterclockwise. Save the plastic and fiber washers. The
number of washers may vary from one unit to another.
On each side of the adjusting screw are two metal screws covered by wax.
Remove and save the wax, and remove the screws.
Slide the rear plastic housing back and expose the internal parts of the unit.
During this operation, for the Model BD-10AS, pull the black plastic button up to
avoid interference while the housing is being removed.
Troubleshooting:
Observe the adjusting screw for worn threads. Replace if this is observed. Note
that on Model BD-10A (unit without switch), some customers incorrectly use the
adjusting knob as an “ON/OFF” switch. This practice prematurely wears out the
threads. Customers must be warned not to do this, but do use a power strip or
similar device to turn the unit on and off.
Next observe the contacts. They must be aligned to each other’s center as much
as possible, and must be corrosion and burn-spot free. If corrosion or burn spots
are observed, clean with a fine file, or replace. Make sure the bottom contact
has enough room on the bottom, so that when the top spring is pushed against it,
the bottom contact does not get pushed into the molded spool core.
