The WC-6 is an AC Yoke which induces a magnetic field into the ferrous material being
tested. The unit should be used within the parameters as set out in the specifications
within this guide. This Manual also applies to Fixed Leg Models, the WC-5.
1. Solid State Push Button Switch –
The Solid State Push Button
Switch was designed for comfort and safety. While depressed, the switch delivers
power (AC) to the coil encapsulated in the Yoke housing.
The Solid State Push Button Switch provides a ½ Watt control signal to the electronic
controls in the Output Module, where semiconductors are used to activate the
magnetization field. Black Modules are for 115V/60Hz and Red are 230V/50Hz.
Do not hold the Push Button Switch on when plugging the Yoke into power.
2. End Cap Rotation –
The End Cap may be rotated to reposition the Cord
Protector (Strain Relief), for operator convenience, within the Bottom 120º or Top
120º of the Junction tube. Carefully remove the End Cap, followed by the internal
Cross Bar, and reposition the power wires. Replace the mounting bar, ensuring the
insulation disk (or tape) is in place and carefully reinstall the End Cap. Care must be
taken not to twist or ‘pinch’ wires, on either the mounting bar or End Cap.
