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% 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%.

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

4.04 Short Circuit Protection While Welding
To prolong the useful life of a TIG tungsten electrode, the Weldskill 200 AC/DC incorporates special circuitry.
In DC LIFT TIG mode, if the tungsten electrode touches the work the welding current is reduced to 20 Amps.
In DC HF TIG mode, if the tungsten electrode touches the work the welding current is reduced to 0 Amps
within 1 second.
In STICK mode, if the electrode touches the work for more than two seconds the welding current is reduced
to 0 Amps.
