Settings pages
In Home menu, push knob to select “Settings”.
Arc characteristics:
Figure 18
Icon Description
Soft arc behaviours. Hot Start and Arc
Force cannot be configured.
Crisp arc behaviours. Hot Start and Arc
Force cannot be configured.
In manual mode user has full access to
Hot Start and Arc Force values.
Arc will be pulsed with frequency, duty
and background current.
The machine allows the user the use 4 stick modes:
Soft: For a welding with a low spatter presence.
Crisp: For an aggressive welding, with an increased
Arc stability. This settings is mainly intended to
cellulosic electrodes.
Manual: user has full control of Arc Force and Hot start
parameters.
Pulse: user can define the frequency, duty, and
welding current.
WARNING
In Soft and Crisp, Hot Start and Arc Force cannot be
modified.
Hot Start:
This is a temporary increase in the initial welding current.
This helps ignite the arc quickly and reliably.
Figure 19
Select the “Hot Start”, push the knob button, change the
value and push again to validate.
Unit is in percentage. In this example the Initial current will
be equal the welding current with 40% of welding current
added.
Example: if welding current is 100A, the Hot Start current
will be 140%.
Arc Force:
This is a temporary increase in the output current during
normal stick welding. This temporary increase in output
current is used to clear intermittent contact between the
electrode and the weld puddle that occur during normal
stick welding.
Figure 20
Anti-Sticking
This feature cannot be modified by user.
This is a function that decreases the output current of the
machine to a low level when the operator makes an error
and sticks the electrode to the work piece. This decrease
in current allows the operator to remove the electrode
from the electrode holder without creating large sparks
that can damage the electrode holder.

Limits:
In this section, an example will be taken to understand
how to limit duty cycle range from 40% to 60% of pulsed
TIG. This procedure must be executed for any parameters
where restriction are expected.
From Home page, TIG parameters are saved in memory
slot n°2 with duty cycle set to 50% (within 40% and 60%).
Figure 34
To define limit, user have to go to “System Options” 
“Memories Management” “Supervisor” or “Operator” 
“Limits & Lockouts” et select memory slot n°2.
As there is currently no restriction, range is maximum from
5% to 95%. Push Select button to configure minimum and
maximum value.

50% displayed is the value previously store in memory.
WARNING
Low limit cannot be higher than value store in memory
and high limit cannot be lower than value store in
memory. Based on this example, if user want to limit duty
cycle from 60% to 70%, user has to save configuration in
memory with duty value between 60% and 70% for
example 65%

TIG Trigger Sequences
TIG welding can be done in either the 2-step or 4-step
mode. The specific sequences of operation for the trigger
modes are explained below.
Legend of the symbols used:
Torch Pushbutton
Output Current
Gas Pre-flow
Gas
Gas Post-flow
2-Step Trigger Sequence
With the 2-step trigger mode and a TIG welding mode
selected, the following welding sequence will occur.
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 preflow
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
increased at a controlled rate, or upslope time, until
the Welding current is reached.
If the torch trigger is released during the upslope time
the arc will stop immediately and the output of the
machine is turned OFF. Release the TIG torch trigger
to stop welding. 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 gas valve will remain
open to continue the flow of the shielding gas to the hot
electrode and work piece.
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.
2-Step Trigger Sequence with Restart Option
If the 2-step restart option is enabled from the setup
menu the following sequence will occur:
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.
