When a different pulse shape is requested the CPU reads the points of the selected
shape. It then converts the point units from percentages to proportional values of
time period (x-axis) and laser power (y-axis). Once the points are converted the
rest of the pulse shape can be derived by interpolating between each point. The
interpolation is provided by the equation below where:
T = Current Time
P
pt
= Power (y) of a given point
T
pt
= Time (x) of a given point
9.9.1 Creating Pulse Shape Files
The pulse shapes can be created with standard CSV (comma separated values)
files. The file must have the following format:
Wave #, x1, y1, x2, y2, x3, y3, x4, y4,
The CSV file should contain the above row as a heading so that the CPU is aware
that the following data is a pulse shape file. Wave # is an integer value from 1 to
10. It determines what pulse wave number the subsequent data in that row is for.
The rest of the values in the row are numbers from 0-100% that determine the (x,y)
point pairs. Note that the first and last points are omitted since they are always
fixed at (0,0) and (0,100) respectively.
The wave CSV file does not have to define every wave number. It can contain just
one, or multiple pulse shapes. Below is an example of a CSV formatted data that
would correspond to a wave file.

9.9.2 Uploading Pulse Shapes
Pulse shape files can be uploaded to the welder unit via the user webpage. Refer
to Figure 57 [▶ 144] which illustrates these steps. For instructions on accessing
the device webpage refer to section 9.3 [▶131].
