Translation of the original instructions
• 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 maximum value is 60 sec.
• Post-Gas button
The Post-Gas adjustment is done by pressing and releasing the Post-Gas button and then activating the main incre-
mental 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 2 seconds. The setting step is 0.1 sec. The
minimum value is 0 sec. and the maximum value is 60 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 2 seconds.
The setting step is 0.1 sec. The minimum value is 0 sec. and the maximum value is 25 sec.
• Incremental encoder for fading or "Down Slop" adjustment
The "Down-Slop" incremental encoder is used to set the value of the gas fading (clockwise increment and counterclo-
ckwise decrement).. The value is visible on the 7-segment display and remains displayed for 2 seconds if an action on
the incremental encoder is performed.
• Cold current control button
When one of the 2 processes "TIG HF" or "TIG LIFT" is selected, key is used to adjust the value of the cold current
(only in 4T Log trigger configuration).. The value can be adjusted between 1% and 99% of the welding current. The
incremental step is 1%. This value is also adjustable in the "TIG DC Pulse" and "MMA Pulse" processes.
• " AC " button
Use of the "AC" button in "AC - Easy" mode : Pressing this button gives access to the tungsten electrode diameter set-
ting. The setting of this parameter is done as follows:
- Press the "AC" key,
- Within 3 seconds, activate the incremental encoder. An clockwise rotation of this encoder leads to an increase in the
electrode diameter and a anti-clockwise rotation leads to a decrease in the value of the electrode diameter. The selected
electrode value is visible on the HMI LEDs below the AC Easy mode.
- Once the setting has been made, after 2 seconds without activating the incremental encoder, it is again linked to the
current setting.
Using the " AC " button in " AC " mode : Pressing this button allows you to select and adjust the " Balance " and " Fre-
quency " parameters (the associated LED lights up according to the selected parameter). The incremental encoder acts
on these 2 parameters values and must be actuated within 5 seconds. Beyond that, the power source will display the
welding current again.
• Frequency adjustment in TIG AC (Frequency)
The welding current frequency setting for TIG AC ranges from 20 Hz to 200 Hz.. The step size depends on the selected
frequency range :
AC TIG frequency (Hz)
[20 Hz ; 50 Hz]
[50 Hz ; 100 Hz]
[100 Hz ; 200 Hz]
• Balance adjustment in TIG AC (Balance)
The welding balance setting for TIG AC ranges from 20 % to 60 %. The incremental step is 1%.
Note: The "AC" key is not active in "DC" mode.
