Translation of the original instructions
The frequency adjustment in TIG DC pulsed is done by pressing and releasing the pulse frequency adjustment button and then operating the
main incremental encoder. Frequency value increases when the incremental encoder is operated clockwise and decreases when it is operated anti-
clockwise. This frequency ranges from 0.1 Hz to 900 Hz.
Once the setting has been done, press the frequency setting button again or wait 5 seconds for the power source to return to the main menu. Pulsed
DC welding is available for the "TIG HF" and "TIG LIFT" processes and the "2T" and "4T" trigger modes.
TIG AC WELDING
• TIG AC - Easy
This mode allows a quick use of AC welding by adjusting the electrode diameter (the selected value is indicated by the different LEDs on the HMI).
With this mode, "Balance" and "Frequency" settings parameters are unchangeable. The choice of the electrode diameter affects the welding current
and the scraping values as follows :
Electrode diameter
1,6 mm
2,4 mm
3,2 mm
4,0 mm
With this mode, the frequency value is related to the welding current value as follows :
Current (A)
10 > 40
41 > 90
91 > 140
141 > 170
171 > 230
• TIG AC - Standard
This TIG AC - Standard welding mode is dedicated to welding aluminium and its alloys (Al, AlSi, AlMg, AlMg, AlMn...). Alternating current (AC) includes
a cleaning phase which is essential for aluminium welding.
The balance: It allows the part to be cleaned during welding. The balance: It allows the part to be cleaned during welding.
The frequency: the frequency is used to adjust the concentration of the arc. A high frequency generates a concentrated arc. A low frequency
generates a wider arc.
High frequency
The AC/DC current-frequency characteristic: In AC, the value of the welding current and its frequency are linked by the function below :
