GENERAL DESCRIPTION
The DA750 is a extremely rugged and compact Magnetic Inspection unit.
All operating controls and output terminals are located on the front panel. A carrying handle
is provided on the top of the unit.
Current output is approximately 750 amperes low voltage A.C. and approximately 750
amperes half-wave D.C. The outputs are based on the use of 30 feet (two 15') cables as a
load.
Optional magnetizing cables can be equipped with prods for circular magnetization. The
cables can also be wrapped around parts to form a "coil" for longitudinal magnetization.
Demagnetization is accomplished in a similar manner.
