Description
Section I: Features
Features
Amada Weld Tech CD-A Dual Pulse Resistance Welding Power Supplies precisely control welding
energy and weld head timing. For the rest of this manual, the CD-A Dual Pulse Resistance Welding
Power Supply will simply be called the Power Supply .
The CD-A125A and CD-A300A contain the same set of control features. The CD-A1000A has all of the
features of the CD-A product family except; the polarity is fixed and upslope is not user settable in the
weld schedules.
•
Multi-function microprocessor control
facilitates multiple applications at a single
work-station and is compatible with both
manual and air actuated weld heads. The
Power Supply provides repeatable process
control and protection from weld schedule
changes by unauthorized personnel.
•
Dual pulse welding can eliminate weld splash
and improve weld quality, especially when
welding plated materials.
•
A peak current monitor displays actual peak
current delivered to the weld on each pulse.
•
User programmable monitor limits on each
pulse can help to detect poor welding
conditions. Programmable test pulses in
conjunction with the
INHIBIT SECOND PULSE
feature can inhibit welding when conditions
are out of limits on the test pulse.
•
The upslope feature improves welding when parts are oxidized, surfaces are contaminated, or parts
do not mate well (this feature is not present in the CD-A1000A).
•
Alternating polarity allows the user to program pulse polarity changes each time the welder is fired.
This allows the user to equalize the wear between two electrodes in many parallel gap welding
processes (this feature is not present in the CD-A1000A).
•
Five relays provide rear panel output signals for
UNIT READY TO WELD, WELD COMPLETED, WELD
OUT OF LIMITS, ALARM,
and
WELD COUNTER PRESET LIMIT.
