1.
Machine status bar: Provides information about the machine's status.
2.
Power: Indicates the laser pulse power from a minimum of 0.5kW up to 5.2kW for single-lamp versions (L0T00F11/L0T0F11N), or 10kW
for dual lamp versions (L0T00F12/L0T0F12N).
3.
Time: Indicates the laser pulse duration from a minimum of 0.5ms up to 25ms for single-lamp versions (L0T00F11/L0T0F11N), or 20ms
for dual lamp versions (L0T00F12/L0T0F12N).
4.
Freq: Indicates the laser pulse repetition rate from a minimum of 0 Hz (single shot at every pedal push) up to 20Hz for single-lamp
versions (L0T00F11/L0T0F11N), or 40Hz for dual lamp versions (L0T00F12/L0T0F12N).
5.
Spot: Indicates the diameter of the welding spot at the focal point of the microscope, from 0.1 mm up to 2.0 mm.
6.
Wave: Indicates the shape of the laser pulse wave: there are 5 waveforms (see Pulse Shaping).
7.
Postgas: Indicates the time that the solenoid valve of the shielding gas remains open after the pedal is released, from 0 seconds (no
activation of the solenoid valve) up to 9 seconds.
8.
LED: increases/decreases the intensity of the lamps inside the welding chamber.
9.
Pregas: This button switches the operation mode of the solenoid valve for the release of shielding gas: when OFF, the pedal activates
the solenoid valve and the laser simultaneously; when ON, pressing the pedal activates only the solenoid valve and pressing it again
activates the laser.
If the Postgas parameter is set to 0, the solenoid valve is not activated and the "Pregas" parameter is ignored.
10.
+ Increases the selected parameter.
11.
- Decreases the selected parameter.
12.
Cam: This button switches the view to the welding chamber, after a few seconds of inactivity on the touch screen the display
automatically shows the welding chamber; touching anywhere on the touch screen the display returns to the welding parameters.
13.
Location of the memory cell pages, there are 70 memory cells displayed 7 at a time.
Refer to chapter "Memory Cells and Saving of Welding Parameters" for more information on the use of the following buttons:
14.
Edit: To change the name of a memory cell.
15.
Save: To overwrite the parameters in a memory cell.
16.
Previous: To view the previous page of memory cells (see Ch. 13)
17.
Next: To view the next page of memory cells (see Ch. 13)
18.
Back: Recalls the parameters used in the last session, cancels the "Edit" and "Save" functions.
Pushing the pedal will generate a laser pulse with an energy amount corresponding to the "Power" value multiplied by the "Time" value, and a
diameter equal to the "Spot" value and a repetition frequency equal to the "Frequency" value. The center of the crosshair viewed through the
eyepieces of the microscope indicates the point of impact of the laser beam.
Waveform (Pulse Shaping)
The laser pulse can make the following waveforms:
Square
A universal wave form where the set energy is delivered for the set time, ideal for all types of metals
Slope Up
Using this waveform the first 20% of the set time provides a gradual increase in the energy until it reaches the set
value, ideal for highly reflective metals
Slope Down
Using this waveform the last 20% of the set time provides a gradual decrease to 0, ideal for opaque or poorly
reflecting metals.
Trapezoid
This waveform is a combination of the previous two, ideal for silver-rich metals.
Pulsed
Using this waveform the energy is generated as a chain of pulses for greater piercing effect, ideal for all metals.
Memory Cells and Saving of Welding Parameters (EDIT/SAVE)
Using the "EDIT" button allows the user to rename the programs in the welding machine. When the "Edit" button is pressed the user will be
prompted to select a cell from those available, press the "Edit" button again to edit and confirm the new name.
