Adjusting pulse times
Pulse times in most applications: 0.05 to 0.5 seconds.
Auto programming calculates the pulse times from the wall thickness. Adjusting the pulse times affects the seam ap-
pearance: A shorter pulse time yields a finer scale.

1. In the main menu, select "Manual/Adjust programming" > "Adjust parameters".
2. Select desired sector.
The respective selected sector is highlighted in color to the right in the display. The angular degree of this sector is
specified. An image of the seam scale appears below the process graphic.
3. Select, highlight, adjust and save the "HP time" and "LP time" parameters.
4. Press softkey 1 ("Weld") or softkey 2 ("Test").
The machine is ready to start.
Recommendation
[
Do not set the high- and low-pulse times with different values.
Experienced users can adjust the pulse times with different values. This is recommended for certain materials
(e.g. copper).
8.3.9
Adjusting weld speed and transition time ("Slope")
Auto programming specifies weld speeds in the range of 70–100 mm/min (at pipe circumference) which lie in the
medium range for the TIG process. As of a certain wall thickness, the system drives the motor in sync with the pulse:
The motor remains nearly still during the high-pulse phase and moves only during the low-pulse phase.
This method reduces the volume of the liquid material so that the melt pool remains under control even with wall thick-
