FLEXTEC™ 500 P
Paralleling Machines
The Flextec™ 500 P power sources may be paralleled for increased
output requirements. No kit is required for paralleling of Flextec™
500 P power sources. The Flextec™ 500 P can only be paralleled for
constant current processes. Connect the power sources as shown on
Figure B2, and set the output control of each power sources to one
half of the desired arc current.
