Programming Parameter
Crater Current
This parameter operates in (4T)
TIG modes only and is used to
set the finish current for TIG.
The CRATER Current remains
ON until the torch trigger switch
is released after it has been
depressed.
Note: The maximum
current available will be limited to
the set value of the base current
and peak current.
Post Flow
This parameter operates in TIG
modes only and is used to adjust
the post gas flow time once
the arc has extinguished. This
control is used to dramatically
reduce oxidation of the tungsten
electrode.
AC Frequency
This parameter operates in AC
TIG mode or AC Pulse TIG mode
and is used to set the frequency
for the AC weld current.
Wave Balance
This parameter operates in AC
TIG modes and is used to set the
penetration to cleaning action
ratio for the AC weld current.
The WAVE BALANCE control
changes the ratio of penetration
to cleaning action of the AC TIG
welding arc. Maximum weld
penetration is achieved when
the WAVE BALANCE control is
set to 10%. Maximum cleaning
of heavily oxidised aluminium or
magnesium alloys is achieved
when the WAVE BALANCE control
is set to 65%.
WAVE BALANCE is used for aluminium welding in DC and AC TIG mode
It is used to set the ratio of penetration to cleaning action for the AC TIG welding arc.
Maximum weld penetration is achieved when the WAVE BALANCE is set to 10%. Maximum cleaning of
heavily oxidised aluminium or magnesium alloys is achieved when the WAVE BALANCE is set to 65%.
