appear throughout the text and are covered here for emphasis.

A

. "

DANGER

" Ground this equipment before operating. Failure to ground this unit

properly may result in electrical shock hazard.

B

. "

CAUTION

" Use safety glasses when operating this equipment.

C.

"

DANGER

" Line current must be disconnected before equipment panels are removed

for any reason. Only qualified electrical personnel should attempt service.

D

. "

CAUTION

" When performing prod inspection with this unit, use very firm contact

pressure to minimize chances of arcing.

E

. "

WARNING

" This equipment produces a strong electromagnetic field which can be

harmful to people with implanted Cardiac Pacemakers. Personnel with such devices

should not operate this machine and must stay a safe distance away from this machine

and cable output area.  Contact the manufacturer of your Pacemaker for additional

precautions and warnings.

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.
