Secondary icon allows to
configure current range.
Hand Remote:
Accessible with Manual remote control and torch with
potentiometer.
User configure the current value only with potentiometer.
Knob on UI has no effect on welding current configuration.
Current range value is defined in secondary icon. In
example below the current range will be from 15A to
270A.
Figure 14
In order to change range value, push knob button and
configure lower and upper limits of current range.

Foot pedal:
Accessible only with Foot remote control.
User configure the minimum current when pedal is barely
press and the maximum current when the pedal is fully
pressed.
The current value display on Home menu correspond to
current according to pedal position.
Torch potentiometer:
Accessible only with Torch potentiometer.
Works like Foot remote control but foot effect is done with
torch potentiometer.
UP-DOWN torch:
Usable only with UP&Down torch.
During welding pushing UP button will smoothly increase
the current value and pushing DOWN button will smoothly
decrease the current value.

SMAW
Figure 17
To choose MMA mode process, select SMAW icon and
push the knob button.
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.

Remote Control
Figure 21
In SMAW mode, two type of remote control can be
selected:
Hand remote control
Pedal Remote control.
For both, behavior is identical to GTAW. Refer to
dedicated section in GTAW chapter.
Gouging
Figure 22
To choose Gouging mode process, select gouging icon
and push the knob button.
Figure 23
Memories
In Home menu, user can save the current welding setup
in dedicated slot by pressing “Memories” button. Welding
process and all cycle parameters are saved and can be
recalled.
Figure 24
Save Memory
Select a slot and hold “Hold To Replace” to save the
current welding. A keyboard will appear allowing user to
name the memory.
Figure 25

English 7 English
Recall Memory
In Home menu, press Memories button. Navigate with
knob to desired memory to load and push Knob button.
An icon with slot number will appear on the top right.
Figure 26
When scrolling through memories slot, border of current
memory slot currently selected is displayed in green.
Otherwise, border will be red.
Figure 27
When a memory is used, user can also Unselect memory.
This action is necessary when Limit & Lockout are set on
memory slot and user needs full control. See Limits &
Lockouts section.
Figure 28
Erase Memories
Memories can be erased. Select “System Options”,
“Memories management” and finally “Edit memories”.
Select the memories you want to erase and push knob
button.
Figure 29
Export / Import memories
To export on USB key memories, plug USB key, then
selection USB key in System Options menu. Finally select
“Backup all settings & memories”.
Figure 30
To load from USB key memories previously saved, select
Load Only Memories.
Memories and PIN settings
When a supervisor code is created, memories can be
locked. See dedicated section Limits & Lockouts.
Memory currently

English 8 English
Limits & Lockouts
Limits & Lockouts allows user to limit or lock some
welding parameters like Preflow time, slope up etc…
This feature is closely linked to Memories and PIN
settings. Limitations and lockouts can only be defined in a
memory slot. User has to load a memory with limited
parameters to use limitation features.
To select and set limits and lockouts, select Memories
management in System Options menu.
If there is no PIN settings used on machine, Supervisor
line cannot be accessed.
A Supervisor (when PIN number is created) can access to
all memories locked or not. An Operator can only access
to unlocked memories.
Figure 31
Memory lock
When a supervisor code is created, locking memory
forbids any modifications of them. When memory is
locked, a lock will be displayed on top-right. To unlock,
push Unlock button.
Figure 32
In Home page, memory number is indicated with a lock.
Any memory modification by erasing are impossible as
long as memory is locked. To replace memory, supervisor
must unlock it before.
Figure 33
Memory limits and lockouts.
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.

English 9 English
Figure 35
Set low limit to 40% and maximum limit to 60%. 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%
Figure 36
In Home menu, when Duty Cycle is selected, areas in
white show inaccessible values.
Figure 37
Lockouts:
In order to lock Duty cycle to only one value. Low and
High limits must be set to same value.
