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.
