HMI OPERATION AND DESCRIPTION OF ITS BUTTONS
On / Off button
•
This key is used to activate or deactivate the machine from sleep mode. The sleep mode cannot be activated while the
machine is welding.
Welding process selection button
•
This key is used to select the welding process. Each successive press toggles between the following welding processes:
TIG HF / TIG LIFT / MMA. The LED indicates the selected process.
Note: the process selected by default at machine startup corresponds to the last process used before the last sleep or
shutdown.
•
Trigger mode selection button
Use this button to configure how the trigger is used. Each successive press toggles between the following modes: 2T /
4T / 4T LOG. The LED indicates the selected mode.
Note: the trigger mode selected by default at machine startup corresponds to the last trigger mde used before the last
sleep or shutdown. For more information, refer to the section "Compatible Torches and Trigger Behavior".
•
Selecting sub-processes button
This key is used to select the "Sub-process". Each successive press toggles between the following sub-processes: PUL-
SE / SPOT (only in TIG mode) / MMA PULSE (only in MMA mode). The LED indicates the selected process.
Note: PULSE mode is only accessible in DC TIG mode.
SPOT mode is not accessible in 4T & 4T Log trigger configuration and in MMA PULSE welding mode.
Note: the sub-process selected by default at machine startup corresponds to the last sub-process used before the last
sleep or shutdown.
•
AC or DC current selection button
This key is used to select the current type when the TIG process is activated. Each successive press toggles between
the following modes : DC / AC / AC - Easy. The LED indicates the selected process.
Note: the process selected by default at machine startup corresponds to the last process used before the last sleep or
shutdown.
Main incremental encoder
•
As default, the incremental encoder allows the adjustment of the welding current.. It is also used to set the values of
other parameters which are then selected via the associated keys. Once the parameter setting has been completed, it is
possible to press the key of the parameter that has just been set again so that the incremental encoder is again linked
to the current setting. It is also possible to press another key related to another parameter to adjust it. The buttons
concerned are the BP1 to BP5 and the adjustment BP in AC. If no action is performed on the HMI for 2 seconds, the
incremental encoder is again linked to the welding current setting.

Setting the Pre-Gas time. This time corresponds
to the time it takes to purge the torch and to

protect the area with gas before ignition
Current rise ramp.
•
•
Pulse frequency setting (only in TIG DC).
•
Cold current setting in PULSE mode.
•
•
•
Current lowering ramp setting.
Post-Gas time setting. This time corresponds to
the duration of gas protection after the arc has
•
•
been extinguished. It protects the weld pool and
the electrode against oxidisation when the metal
is cooling down.
