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 crater
current available will be limited to
the set value of the weld current.
Amps
5 to 200A (DC TIG mode)
30 to 200A (AC TIG mode)
10 to 200A (AC HF TIG mode)
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 only and is used to
set the frequency for the AC weld
current.

Wave Balance
This parameter operates in AC
TIG mode and is used to set the
penetration to cleaning action
ratio for the AC weld current.
Generally WAVE BALANCE is set
to 50% from the factory for AC
TIG Welding. 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 oxidized aluminium or
magnesium alloys is achieved
when the WAVE BALANCE control
is set to 65%.

WAVE BALANCE is used for aluminium welding in AC HF TIG or AC LIFT 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
oxidized aluminium or magnesium alloys is achieved when the WAVE BALANCE is set to 65%.
