See paragraph 6.1 for sequence of changing parameters of functions.
5.2 FUNCTION OF VOLTAGE FADE-OUT IN THE END OF WELDING
This function is designed for smooth filling of a crater, which is formed in the
weld pool by the action of electromagnetic draft of the electric arc and subsequently
becomes a source of weld defects. Release of the torch button in the end of welding
becomes the signal to start the function. Once this happens, stop moving the torch
and weld the pothole (which is a crater) in the weld with fading-out voltage.
Smoothness of this process can be controlled through voltage fade-out time [t.dn],
which is set to 1.0 s by default and can be changed at user's discretion. See paragraph
6.1 for the procedure of changing.
5.3 PULSED VOLTAGE WELDING FUNCTION
This function is designed to facilitate control over welding process in spatial
positions other than downhand position, as well as during welding of non-ferrous
metals. This function affects directly weld metal dilution, therefore it primarily
affects the shape of weld. It also forces drop transfer from the filler wire into the
