HMI OPERATION AND DESCRIPTION OF ITS BUTTONS
Button Sleep timer / Standby exit button
This key is used to activate or exit the unit from 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 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.
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 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 process.
Note : SPOT mode is not accessible in 4T & 4T LOG trigger configuration and in MMA 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
As default, the incremental encoder allows the adjustment of the welding current.. It is also used to set the values of other para-
meters 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 2 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 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 Pre-Gas button again to re-link the main incremental
encoder to the current setting or to wait for 2 seconds. The setting step is 0.1 sec. The minimum value is 0 sec. and the maxi-
mum value is 25 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 re-press and release the Pre-Gas pushbutton to re-link the main
incremental encoder to the current setting or to wait 2 seconds. The setting step is 0.1 sec. The minimum value is 0 sec. and the
maximum value is 25 sec. The default value is 6sec.
«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 2 seconds. The setting step is 0.1 sec. The minimum
value is 0 sec. and the maximum value is 25 sec. The default value is 0sec. In MMA mode, the Hotstart is adjustable between 0
and 100% of the welding current in 5% steps. The default value is 40%.
Potentiometer for setting the fading or «DownSlope».
The «DownSlope» potentiometer is used to adjust the value of the current fading (clockwise increment and counterclockwise
decrement). The value is visible on the 7-segment display and remains displayed for 2 seconds if an action on the potentiometer
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 «TIG HF» or «TIG LIFT» is selected, the cold current setting button is used to adjust the cold
current value only in the «PULSE» configuration. The value can be adjusted between 20% and 80% of the welding current. The
incremental step is 1%. The default value is 30%.
In MMA mode, the Arc Force is indexed from -10 to +10 (-10 = no Arc Force / -9 to +10 = Arc Force setting possible).
The default index value is 0.
