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 mode 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: PULSE / SPOT (only in TIG mode)
/ MMA PULSE (only in MMA mode). The LED indicates the selected sub-process.
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. If no action is performed on the HMI for 5 seconds, the incremental encoder is again linked to the welding current setting.
Pre-Gas button
•
The Pre-Gas adjustment is done by pressing and releasing the Pre-Gas button and then activating the main incremental encoder. Pre-Gas value in-
creases when the incremental encoder is operated clockwise and decreases when it is operated anti-clockwise. Once the setting has been made, it
is possible to press and release the Pre-Gas button again to re-link the main incremental encoder to the current setting or to wait for 5 seconds. The
setting step is 0.1 sec. The minimum value is 0 sec. and the maximum value is 20 sec.
Post-Gas button
•
The Post-Gas adjustment is done by pressing and releasing the Post-Gas button and then activating the main incremental encoder. Post-Gas value
increases when the incremental encoder is operated clockwise and decreases when it is operated anti-clockwise. Once the setting has been made, it
is possible to press and release the Post-Gas button again to re-link the main incremental encoder to the current setting or to wait for 5 seconds. The
setting step is 0.1 sec. The minimum value is 0 sec. and the maximum value is 20 sec.
• Up Slop or current control button
The curremt ramp-up setting is done by pressing and releasing the current ramp-up button and then by activating the main incremental encoder.
Current ramp-up value increases when the incremental encoder is operated clockwise and decreases when it is operated anti-clockwise. Once the
setting has been made, it is possible to press and release the current ramp-up button again to re-link the main incremental encoder to the current
setting or to wait for 5 seconds. The minimum value is 0 sec. and the maximum value is 20 sec.
• Incremental encoder for fading or "Down Slop" adjustment
The "Down-Slop" incremental encoder is used to set the value of the current fading (clockwise increase and counterclockwise decrease). The value
is visible on the 7-segment display and remains displayed for 5 seconds if an action on the incremental encoder is performed. The minimum value
is 0 sec. and the maximum value is 20 sec.
• Cold current control button
When one of the 2 processes "HF TIG" or "LIFT TIG" is selected, the cold current setting button is used to adjust the value of the cold current (only
in 4T Log trigger configuration). The value can be adjusted between 20% and 80% of the welding current. The incremental step is 1%. This value is
also adjustable in the "TIG DC Pulse" and "MMA Pulse" processes.
