Pulse break time/slope time from AMP to AMP%
• Pulse break setting range: 0.01 sec to 20.0 sec
(0.01 sec increments < 0.5 sec; 0.1 sec increments > 0.5 sec)
• Slope time (tS1) setting range: 0.0 sec to 20.0 sec
> see 5.3.13 chapter
TIG pulses: The pulse break time applies to the secondary current phase (AMP%)
TIG AC Special: The pulse break time applies to the DC phase with AC special.

TIG pulses
The pulse time applies to the main current
phase (AMP) for pulses.
TIG AC Special
The pulse time applies to the AC phase for
AC special.
