Integrated Ultrasonic Plastic Welder
2000IW / 2000IW+ Series
These Integrated Welders are self-contained
ultrasonic plastics assembly systems that combine
a power supply module, process controls,
and welding stand in a compact bench unit.
The system is available with power output of
1100 or 2200 Watts at 20 kHz working frequency.
Beside time mode the IW+ model enables distance
welding in either collapse or absolute
modes with limits.
Apart from special characteristics the concept
IW/IW+ is based among others on the following
standard characteristics of 2000 series: Autotune
plus Memory (AT/M), Dynamic Triggering, System
Protection Monitor (SPM), upper limit switch, highprecision
pressure regulator, calibrated flow control,
adjustable mechanical stop.
Key Features
Line/Load Regulation - Corrects for variations due
to power line fluctuations and varying load conditions
through Branson‘s patented closed-loop amplitude
control. Output amplitude is maintained with a variation
of only +2% with line voltage fluctuations of
+10%, regardless of load. It ensures constant power
in welding, and provides greater weld consistency
and reliability.
A single 20 kHz Converter is used for all 20 kHz
power supplies. It produces 20% higher output
amplitude for faster weld cycles.
Auto Seek automatically measures stack frequency
and stores it in memory. Three selectable Auto Seek
choices are available.
Activating on power up for the initial weld.
Activating via “test“ switch checks stack frequency
and sets memory by pressing the „test“
switch
Interval activating checks stack frequency and sets
memory by once/minute timer
Starting ramp with four selectable start rates (10,
35, 80, 105 milliseconds) to accomodate starting
characteristics of a wide range of horns. This feature
make it easier to start more difficult horns or enables
faster cycle rates.
Operating mode of model IW: It features welding in
time; ultrasonics and force are applied to parts for a
precise, preset time, and parts are held under force
for a precise hold time; adjustable afterburst delay
and duration times may be set, if required. Display of
time and afterburst parameters is digital.
Operation mode of model IW+: This model gives
choice of time or distance modes (either absolute
or collapse). In absolute, the weld is terminated
at a predetermined point in the stroke, measured
from the top of the stroke. In collapse, the weld is
terminated at a predetermined point in the stroke
after the horn contacts the part and the trigger switch
is activated. The position display is digital. With
position modes, upper and lower limit ranges may
be selected.
Digital and direct parameter entry with autoranging
when entering parameters gives precise settings for
repeatable accuracy. The autorange values enable
fine resolution and setup accuracy.
A linear optical encoder measures weld „distance"
enabling welding by specific part collapse (meltdown),
or to a finished part height (absolute).

Afterburst with variable delay and duration is
available to dislodge a part or material adhering
to the horn face.
Individual select keys allow easy selection of
parameters to be modified. Active choice is lighted.
Self-diagnostics and cycle monitoring features
and capabilities provide fast, accurate trouble shooting
and minimize downtime. During initial powerup,
the unit completes a selfcheck and identifies
any fault conditions or parameter errors before
indicating that the system is „ready“ for operation.
Visual and audible alarms and external outputs
identify overload, machine faults and setup errors
(e.g. emergency stop engaged).
Fast-response LED storage meter displays power
loading in 5% increments, and provides storage of
the peak power achieved during the weld cycle as
well as better visibility; 100% of rated output of the
power supply is delivered at full meter reading.
Peak power reading from the last welding cycle is
available on the digital LED display by depressing
the „reset“ switch. Similarly, power in the tuning
mode is digitally displayed when the „test“ switch
is depressed.
LED readouts display parameter settings during
setup and operation for easy reference and
monitoring. LEDs are large and easy to read in
most light conditions.
Lockout of front panel switches is provided by
and internal dip switch, preventing unauthorized
parameter changes to the setup.
Nonvolatile storage of cycle parameters provides
storage of last-used cycle parameters even if the
system is shut off or a power interruption occurs.
Automation Interfacing
Series Integrated Welders can be interfaced with
external devices and controls (e.g., PLCs).
• Select faults or weld errors sensed by the system
can be communicated outside the welder
for monitoring and sorting suspect parts.
• General alarm and weld on outputs are available
for customer access through 24V DC negative
logic devices. The ready signal is both a
24VDC and isolated contact closure.
• Reset is available via front panel or external
for customer access as a 24V DC input. A 24V
source is provided by the welder.
