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.
Bi-Level (A1/A2) Trigger sequence
The Bi-Level feature is selectable only if the "option 20"
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). Each time this trigger
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.
