WC-9UW
2
The WC-9UW allows the Operator to induce a Pulsing DC inspection field
(125Hz) into the ferrous material being tested. The unit is tested to Pressures of
75 PSI (150 below sea level) for extended periods. The device should be utilized
within the parameters set by the operational specifications within this guide.
1. Switch System
The WC-9UW is activated by means of the Module Switch Plunger Assembly.
A small, sealed, WC-Series Switch is mounted on the special Switching
Module, which pulses the 13.2 DC Battery Voltage as it delivers it to the coil
encapsulated in the Yoke housing. To activate this switch, the operator
simply rotates the Switch Plunger approximately ¼ turn.
When installing the Battery Pack, after charging, fit the Switching Module into
the connector at the bottom of the Junction Tube. Ensure the Urethane
Spring is positioned in the bottom of the Junction Tube, and line up the
Connectors in the bottom of the Junction Tube and on the Switching Module.
Then Carefully slide the Battery Pack into the Junction Tube,
feeling
the
mating connectors together. After the Battery Pack is in place, simply hand
tighten the 4, 10-24 x ¼” fasteners to retain the Battery Pack to the Junction
Tube. Press the Switch Plunger into the Battery Pack, until it stops against
the threads cast inside the Pack housing. Carefully rotate the Plunger until
the handle is about 3/8” from the end of the Battery Pack housing. Place the
