Parameter Description
WELD 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.
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 300 TS memory.
