Post-flow time

Pulse current

Pulse frequency
Applicable if the PULSE selection button is set to "ON" in TIG
MODE.
It means the number of repeat times per second of the com-
bined waveforms of pulse current and welding current (as
shown in the following diagram as T(1Hz)).

Pulse width
Applicable if the PULSE selection button is set to "ON" in TIG
MODE.
With regard to the pulse frequency waveform, it is obtainable
from the following formula as the ratio between pulse current
width ("tp" in the right figure) and the total value of pulse cur-
rent width and welding current width ("T" in the right figure).
Pulse width (%)=(tp / T) x 100
