INSTALLATION, OPERATION AND SETUP
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%.

Table 3-4: GTAW Main Parameters
AC BALANCE is used for aluminium welding in AC HF GTAW or AC LIFT GTAW operating modes
It is used to set the ratio of penetration to cleaning action for the AC GTAW welding arc.
