Tig Ac Welding - GYS PROTIG 201 AC/DC Mode D'emploi

Translation of the original instructions

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) Frequency (Hz)
De 10 à 40 117
De 41 à 90 100
De 91 à 140 79
De 141 à 170 70
De 171 à 200 60
When switching from "AC - Easy" to "AC" mode, the last welding parameters "AC - EASY" are retained and can be used
as a basis for further refinement in "AC" (e.g. : welding frequency and balance).
• 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 PROTIG 201 AC/DC and PROTIG 201L AC/DC current-frequency characteristic: In AC, the value of the welding
current and its frequency are linked by the function below :

Up to 100 Hz it is possible to weld at
a welding current of 200 A. Between
100 Hz and 200 Hz, the maximum

decreases from 200 A to 150 A.
