6.4 Setup Procedure
In either Time or Distance modes, pressing both START SWITCHES within 100 to 200 ms
of each other starts a weld cycle. Ultrasonic energy starts and you may release the START
SWITCHES when trigger conditions are met, It remains on until the weld parameters are
met or until a general alarm or EMERGENCY STOP occurs.
1. If your application has been analyzed in the Branson Application Laboratory, consult the Branson
Lab Report for appropriate settings. Otherwise, start with the following welder settings:
• Mode - Time
• Weld Time - 500 ms
• Hold Time - 100 ms
• Air Pressure - 25 psig/140kPa
• Trigger Pressure - 1 - 5
• Down Speed - 3 turns (Yellow)
• Afterburst Time/Delay - OFF
• Stroke Length - 1/4 to 3 - 3/4 in/6.35 to 95.25mm
2. Adjust the mechanical stop (for further information, see Figure
Figure 4.23 Adjusting the
Mechanical Stop).
3. Ensure that the welder is in READY mode.
4. With a workpiece in place, press both START SWITCHES simultaneously or activate the start
mechanism. The weld cycle will start, as follows:
a The horn advances and contacts the workpiece.
b Pressure develops between the horn and the workpiece, activating the TRS.
NOTICE
Push the E-STOP button to terminate the cycle at any time. This causes the carriage to
retract and ultrasonic energy to shut off. Twist the E-STOP button to return the welder
to READY.
NOTICE
For 900 IW/IW+ users: when transferring an application to the 2000IW/IW+ welder;
use a booster ratio 1 step lower than your prior setup and use 1/2 the force as a
starting point. This is due to line and load regulation features in the ultrasonic power
supply module, and enhanced converter performance.
NOTICE
Trigger Pressure: Lower trigger pressure settings are generally used unless there is a
need to overcome warpage or to compress internal components such as springs,
diaphragms or seals.
NOTICE
Down Speed: If the DOWN SPEED control is turned OFF (fully clockwise), the carriage
will not descend. As an initial setting, turn the control until the yellow ring or yellow and
blue rings are visible through the opening on the knob.
