Features
Miyachi Unitek
125ADP/300ADP/1000ADP Dual Pulse Resistance Welding Power Supplies
precisely control welding energy and weld head timing. For the rest of this manual, the
ADP Dual
Pulse Resistance Welding Power Supply
will simply be called
the Power Supply
.
The 125ADP and 300ADP contain the same set of control features. The 1000ADP has all of the
features of the ADP product family except the polarity is fixed and not user settable in weld schedules.
In addition, the pulse width is not user settable in weld schedules. Both the polarity and pulse width are
set in the 1000ADP at the Factory prior to shipment.

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.

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 1000ADP)

Five
relays
provide rear panel output signals for
UNIT READY TO WELD, WELD COMPLETED, WELD
OUT OF LIMITS, ALARM,
and
WELD COUNTER PRESET LIMIT.
