Setting
AC balance
(AC Output Mode only)
This parameter operates in AC
GTAW modes and is used to set the
penetration to cleaning action ratio
for the AC weld current. Generally
WAVE BALANCE is set to 50%
for AC Stick 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
oxidised aluminium or magnesium
alloys is achieved when the WAVE
BALANCE control is set to 65%.
