HMI OPERATION AND DESCRIPTION OF ITS BUTTONS
Sleep Mode / Sleep Exit
This key is used to activate or exit the standby mode. Activation of the mode is not possible when the product is in welding
condition.
Note: When the power is turned on, the product starts in standby mode.
Welding process selection button
This button is used to select the welding process. Each successive press/release switches between the following welding
processes: TIG HF / TIG LIFT / MMA. The LED indicates the selected process.
Trigger mode selection button
This button is used to set the trigger operation mode of the lamp. 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 Behaviour».
Process options selection button
This key allows the selection of the «Sub-process». Each successive press toggles between the following modes: PULSE /
SPOT / SPOT-PULSE (only in TIG mode) / MMA PULSE (only in MMA mode). The LED indicates the selected process.
Note: SPOT mode is not accessible in 4T & 4T Log trigger configuration and in MMA PULSE welding mode.
MMA PULSE welding mode is not accessible in 4T & 4T LOG trigger configuration
Note: the sub-process selected by default at machine startup corresponds to the last sub-process used before the last
sleep or shutdown.
Main incremental encoder
By default, the incremental encoder allows the setting 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 setting is set, it is possible to press the key of the
setting 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 incre-
mental 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 increases when the incremental encoder is operated clockwise and decreases when it is operated
anti-clockwise. Once the setting has been set, 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 Pre-Gas adjustment is done by pressing and releasing the Pre-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 ope-
rated anti-clockwise. Once the setting is set, it is possible to press and release again the Pre-gas button to re-link the main
incremental encoder to the current setting or to wait 5 seconds. The setting step is 0.1 sec. The minimum value is 0 sec.
and the maximum value is 20 sec. The default value is 3 sec.
«UpSlope» current adjustment button.
The current ramp is set by pressing and releasing the current ramp button and then operating 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 set, 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 setting step is 0.1 sec.
The minimum value is 0 sec. and the maximum value is 20 sec. The default value is 0sec. In MMA mode, the Hotstart is
adjustable between 0 and 100% of the welding current in 1% steps. The default value is 40%.
