WAVE BALANCE
This parameter is used for aluminium 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 aluminum or magnesium alloys is achieved when the WAVE BALANCE control
is set to 65%.
DOWN SLOPE
This parameter operates in TIG modes only and is used to set the time for the weld current to
ramp down, after the torch trigger switch has been pressed, to CRATER CUR. This control is
used to eliminate the crater that can form at the completion of a weld.
CRATER CUR.
This parameter operates in SLOPE or REPEAT (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.
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.
The SAVE/LOAD buttons are used to save and retrieve a total number of 5 programs into the
185/200ACDC memory.
