TRANSARC 130i
Manual 0-5283 3-7 INSTALLATION, OPERATION AND SETUP
Base Current
This parameter sets the TIG welding
current.
Range is 5 to 130A. Factory default
is 120A.
Down Slope
This parameter operates in TIG
mode only and is used to set
the time for the weld current to
ramp down to the crater current.
This control is used to eliminate
the crater that can form at the
completion of a weld.
Range is 0.0 to 25.0 seconds.
Factory default is 3.0 seconds.
Crater Current
This parameter operates in TIG
mode only.
In 2T mode this is the current at
the end of the down slope current
ramp. When the welding current
reaches the Crater Current value,
the welding current will cease and
the unit will enter Post Flow mode.
In 4T mode, this is the current at
the end of the down slope current
ramp. The welding current will
remain at the Crater Current value
until the torch trigger is released, at
which time the welding current will
cease and the unit will enter Post
Flow mode.
Range is 5 to 130A. Factory default
is 30A.
