Parameter Description
PEAK CUR.
(WELD)
This parameter sets the PEAK weld current when in PULSE mode
This parameter sets the TIG WELD current in STD , SLOPE , REPEAT and
SPOT modes when PULSE is off. This parameter also sets the STICK
weld current.
BASE
(Background
Current)
This parameter sets the Background current when in Pulse TIG mode.
SPOT TIME
This parameter sets the duration of the SPOT TIME in HF TIG mode only
PULSE WIDTH
This parameter sets the percentage on time of the PULSE FREQUENCY
for PEAK weld current when the PULSE is on.
PULSE FREQ.
This parameter sets the PULSE FREQUENCY when the PULSE is on.
AC
FREQUENCY
This parameter operates in AC mode only and is used to set the frequency
for the AC weld current.
WAVE
BALANCE
This parameter is used for aluminium AC TIG mode and is used to set the
penetration to cleaning action 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%.
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.
