Up Slope Time
This parameter operates in
GTAW modes only and is used to
set the time for the weld current
to ramp up from Initial current to
welding current.

Trough Current A2
This parameter operates in
GTAW Pulse modes only and
sets the GTAW TROUGH current.
The lowest point in the pulse is
called the Trough.
1 – 200% of Welding
Current A1
The maximum
welding current
in GTAW mode is
limited to 220 for
the Transtig 220AC/
DC and 200A for the
Transtig 300AC/DC
50
Down Slope Time
This parameter operates in
GTAW modes 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.

20
Crater Current AE
This parameter operates in
GTAW modes only.
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 Crater Current Time
has elapsed, at which time the
welding current will cease and
the unit will enter Post Flow
mode. This control is used to
eliminate the crater that can
form at the completion of a weld.

Current A1
The maximum
welding current
in GTAW mode is
limited to 220 for
the Transtig 220AC/
DC and 200A for the
Transtig 300AC/DC
25
Crater Current Time tE
This parameter operates in
GTAW modes only and is used to
set the time for the crater current
before entering post flow mode.
This control is used to eliminate
the crater that can form at the
completion of a weld.
0 – 20 seconds
0.2
Shielding Gas Post-Flow time
This parameter operates in GTAW
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.
