Section 5 - Process Control Settings
Dukane Manual Part No. 403-577-01
Process Controller
Settings
This section of the manual helps the reader become
familiar with the operating modes, and illustrates some
typical programming steps.
There are three welding modes available. These
correspond to the three ways in which the welder can be
used: Manual, Time, and Energy.
Select the Welding Mode
Manual - In MANUAL mode the operator controls
the weld cycle. The cycle starts when the operator presses
the hand probe’s trigger switch, and the ultrasonic signal
(U/S) activates. When the trigger switch is released,
the ultrasonic signal stops, and the cycle is complete.
(Manual mode is the default selection.)
Time - In TIME mode the operator sets a maximum
time (seconds) the ultrasonic signal will be active for
each weld cycle. The cycle starts when the hand probe’s
trigger switch is activated, and the U/S activates. The
U/S stops when the programmed time is reached. The
trigger switch must be held activated for the entire
welding cycle. Then it is released so that a new weld
cycle can begin.
Energy - In ENERGY mode the operator sets a
maximum energy (Joules) the generator will reach
during the weld cycle. [A maximum weld time must be
set when welding by energy. If the energy level is not
reached, the preset for time will determine when the U/S
is deactivated.] When the preset energy level is reached,
the U/S will be deactivated. The cycle starts when
the hand probe’s trigger switch is pressed, and U/S is
activated. When the programmed energy is reached, U/S
stops. The trigger switch must be held activated for the
entire welding cycle. Then it is released so that a new
weld cycle can begin.
NOTE
With one exception, U/S is acti-
vated anytime the probe’s trigger
switch trigger is pressed regard-
less of operating mode, or what is
displayed on the LCD screen.
The EXCEPTION - When a fault
has occurred in Latching Fault
Mode. In that case ENTER must
be pressed to clear the fault be-
fore U/S can be activated.
