Branson 900IW+ Series - Weld Modes and Parameter Settings

4.1 Weld Modes
The 900IW+ welder has three weld modes, all accessed by pressing the
MODE switch on the front panel:
•
Time mode — use when cycle time repeatability is critical
•
Collapse Distance mode — use where material displacement is
important
•
Absolute Distance mode — use when final dimensions are critical
The following sections describe how to modify modes, followed by details
on using weld modes.
4.1.1 Modifying Weld Modes
Weld modes can be modified by setting
parameters
for further control
over the weld cycle. You can also set
limits
that you can compare with
actual values
for monitoring and greater weld accuracy. In addition, you
can set ultrasonics to start on the trigger switch (TRS) or to be
pretriggered.
You can also adjust the carriage's down speed. These features are
discussed in the following subsections. Refer to Section 4.1.2 for details on
how to apply the features.
a. Parameters
Weld modes can be
controlled
from the front panel by adjusting Time,
Collapse and Absolute Distance parameters, depending on the selected
mode. Hold Time and the
selectable
Afterburst (AB) Time and
Afterburst (AB) Delay parameters can be adjusted from all three
welding modes.
Note that, while AB Time and AB Delay are selectable, they do not
have
to be set. The two parameters work in tandem - if AB Time is
selected, then AB Delay must also be selected. Afterburst is used to
release workpieces that stick to the horn face after welding.
