Tig Process:
In TIG welding process, gas usage depends on cross-sectional area of the nozzle. For commonly used torches:
Helium: 14-24 l/min
Argon: 7-16 l/min
Notice: Excessive flow rates causes turbulence in the gas stream which may aspirate atmospheric contamination into
the welding pool.
Notice: A cross wind or draft moving can disrupt the shielding gas coverage, in the interest of saving of protective gas
use screen to block air flow.

English
4-Step Trigger Sequence
With the 4-step trigger mode and a TIG welding mode
selected, the following welding sequence will occur.
As shown above, it is possible to press and hold the TIG
torch trigger a second time during downslope to end the
downslope function and maintain the output current at
the Crater current. When the TIG torch trigger is
released the output will turn OFF and the post flow time
will start. This operation sequence, 2-step with restart
disabled, is the default setting from the factory.
1. Press and hold the TIG torch trigger to start the
sequence. The machine will open the gas valve to
start the flow of the shielding gas. After the pre-flow
time, to purge air from the torch hose, the output of
the machine is turned ON. At this time the arc is
started according to the selected welding mode.
After the arc is started the output current will be at
the Start current. This condition can be maintained
as long as necessary.
2-Step Trigger Sequence with Restart Option
If the 2-step restart option is enabled from the setup
menu the following sequence will occur:
If the Start current is not necessary, do not hold the
TIG torch trigger as described at the beginning of this
step. In this condition, the machine will pass from
Step 1 to Step 2 when the arc is started.
2. Releasing the TIG torch trigger starts the upslope
function. The output current will be increased at a
controlled rate, or upslope time, until the Welding
current is reached. If the torch trigger is pushed
during the upslope time the arc will stop immediately
and the output of the machine is turned OFF.
3. 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.
1. Press and hold the TIG torch trigger to start the
sequence as described above.
2. Release the TIG torch trigger to start the
downslope. During this time press and hold the TIG
torch trigger to restart welding. The output current
will increase again at a controlled rate until the
Welding current is reached. This sequence can be
repeated as many times as necessary. When the
welding is complete release the TIG torch trigger.
When the Crater current is reached the output of the
machine is turned OFF.
4. This Crater current can be maintained as long as
necessary. When the TIG torch trigger is released
the output of the machine is turned OFF and 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 turn OFF.
This sequence operation, 4-step with restart disabled, is
the default setting from the factory.
English
12
English
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):
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.
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.
With this sequence the arc is started as in the 4S
sequence, this means that steps 1 and 2 are the same.
4. Release the TIG torch trigger. The output current
will again increase to the Welding current, like in
step 2, to continue welding.
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.
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.
NOTE: The Restart option and the Pulse function are
not available for Bi-Level Trigger sequence.
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.
Spot sequence.
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.
English
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.
