4-Step Trigger Sequence with Restart Option
If 4-step restart is enabled from the setup menu the
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 post flow
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.
When the TIG
torch trigger is released
the
output
will
again
increase to the Welding
current, like in step 4, to continue welding. When the
main part of the weld is complete go to step 3.
As shown here, again
after the TIG torch trigger
is quickly pressed and
released from step 3A, it is
possible to quickly press
and release the TIG torch
trigger a second time to
end the downslope time
and stop welding.

4-STEP Bi-Level Trigger sequence
When this sequence is selected, a new icon appears on
the right allowing to configure the second level current
value. In this example, the background current level will
be 25% of welding current value.
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. The 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.
Spot sequence.
In Spot sequence, the trigger (step 1) starts the welding
sequence. Unlike other parameters, the end of cycle
does not depend of trigger action: a time set on UI will
initiate automatically the slope down phase.
The time configuration is between (2) and (3) arrows.
