
MIX frequency
Applicable to the MIX TIG welding.
It means the number of repeat times per second of
the waveform shown as (1Hz) in the right diagram.
MIX frequency
(1Hz)
AC DC

DC ratio
Means the MIX (DC) ratio and is applicable to the
MIX TIG welding.
With regard to the MIX frequency, it is obtainable
from the following formula as the ratio between the
width of a DC waveform (tad in the right diagram)
and the width of a waveform per 1Hz in MIX fre -
quency (Tmix in the following diagram).
DC ratio (%)=(tad / Tmix) X 100


AC frequency
Applicable to AC TIG welding or MIX TIG welding.
It means the number of repeat times per second of the
waveform shown as (1Hz) in the rightdiagram.
