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 2 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 2 seconds. The setting step is 0.1 sec. The minimum value is
0 sec. and the maximum value is 25 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 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.
«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 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. In MMA mode, the Hotstart is
adjustable between 0 and 100% of the welding current in 5% steps. The default value is 40%.
DownSlope adjustment potentiometer
The «DownSlope» potentiometer is used to adjust the current fade value (clockwise increment and counterclockwise de-
crement). The value is visible on the 7-segment display and remains displayed for 2 seconds if an action on the potentio-
meter is performed. The minimum value is 0 sec. and the maximum value is 20 sec.
Cold current adjustment button
When one of the 2 processes «HF TIG» or «LIFT TIG» is selected, the cold current setting button is used to adjust the va-
lue of the cold current (only in «4T LOG» or «PULSE»). The value can be adjusted between 20% and 99% of the welding
current. The incremental step is 1%. The default value is 50%.
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.
WELDING WITH RUBBERED ELECTRODE (MMA MODE)
CONNECTIONS AND RECOMMENDATIONS
• Connect the electrode holder and earth clamp to the corresponding sockets.
• Ensure that the welding polarities and intensities indicated on the electrode packaging are observed.
• Remove the electrode from the electrode holder when the machine is not in use.
CHOICE OF COATED ELECTRODES
• Rutile electrode: very easy to use in all positions with DC current
• Basic electrode: used in all CC positions, it is suitable for safety work due to its increased mechanical properties.
