following sequence will occur for steps 3 and 4 (steps 1
and 2 are not altered by the restart option):
3. Press and hold the TIG torch trigger. The machine
will now decrease the output current at a controlled
rate, or downslope time, until the Crater current is
reached.
4. Release the TIG torch trigger. The output current will
again increase to the Welding current, like in step 2,
to continue welding.
If the weld is completely finished, use the following
sequence instead of step 3 described above.
3A.
Quickly press and release the TIG torch
trigger.
The machine will now decrease the
output current at a controlled rate, or downslope
time, until the Crater current is reached and the
output of the machine is turned OFF. After the
arc is turned OFF the postflow time will start.
As shown here, after
the TIG torch trigger is
quickly
pressed
and
released from step 3A,
it is possible to press
and hold the TIG torch
trigger another time to
end
the
downslope
time and maintain the
output current at the
Crater current.

is previously enabled in the Setup Menu.
To select Bi-Level sequence:
Action
Press several times until the LED above lights up
With this sequence the arc is started as in the 4S
sequence, this means that steps 1 and 2 are the same.
3.
Quickly press and release the TIG torch trigger.
The machine will switch the current level from A1 to
A2 (background current).
action is repeated the current level will switch
between the two levels.
3A.
Press and hold the TIG torch trigger when
the main part of the weld is complete.
machine will now decrease the output current at
a controlled rate, or downslope time, until the
Crater current is reached. This Crater current
can be maintained as long as necessary.
NOTE: The Restart option and the Pulse function are not
available for Bi-Level Trigger sequence.
