En soudage TIG AC à onde carrée, le temps de pre-flow et de post-flow sont les même qu’en soudage TIG DC, et les autres
sont décrits ci-dessous :
• Courant initial (I0), courant de soudage (I1) & courant de l’arc pilote (I2) : La valeur prédéfinie de ces 3
paramètres est approximativement la moyenne absolue du courant de soudage pratique, et peut être réglée en fonction des
exigences techniques de l’opérateur.
• Fréquence d’impulsion (1/tp): Elle peut être réglée en fonction des exigences techniques de l’opérateur.
• Force de nettoyage (100%*Tc/Tp): Généralement, en soudage AC, quand on prend l’électrode comme anode, le
courant est appelé courant de cathode. Sa fonction principale est de briser la couche oxydée de la pièce, et la force de
nettoyage est le pourcentage de courant de cathode pendant la période AC. Ce paramètre est habituellement de
10~40 %. Quand la valeur est plus petite, l’arc est concentratif, le bain de fusion est étroit et profond, et quand la valeur
est plus grande, l’arc est dispersif, le bain de fusion est large et peu profond.

Fig 10.16 AC Pulse TIG Current Change Waveform
AC pulsed TIG welding is almost the same as AC square wave TIG welding, and what makes them
different is that in AC pulsed TIG welding, the welding current varies with the pulse and peak current and
base current are generated because the welding current is controlled by a low frequency pulse. The
preset peak current and base current are the low frequency pulse peak value (average value) and base
value (average value) respectively. For the AC square wave parameter selecting and setting, please
refer to the corresponding contents in AC square wave TIG welding. For the pulse frequency and pulse
duration ratio, users may refer to the corresponding contents in DC pulsed TIG welding. The pulse
frequency (1/T) is a little low, and it can be adjusted between 0.5Hz and 5Hz. The pulse duration ratio
(Tp/T) can be adjusted between 10% and 90%.
10.5 TIG operation mode
TIG operation mode is a kind of special stipulation, which stipulates the modes to control welding
current through different operation of the torch trigger in TIG (DC TIG, pulsed TIG and AC TIG) welding.
The introduction of TIG operation mode strengthens the application of remote control function of the
torch trigger, so that users can get practical remote controls for welding machines without further
investment.
TIG operation mode should be selected according to users’ technical requirements and operating
habits. All the TIG operation modes for this machine are listed in the table TIG operation modes below.

Fig. 8.16 Forme d’onde du changement de courant en soudage TIG courant pulsé AC
Le soudage TIG courant pulsé AC est presque pareil au soudage TIG AC à onde carrée, et ce qui les différencie est que
dans le soudage TIG courant pulsé AC, le courant de soudage varie avec l’impulsion et un courant de crête et un courant
secondaire sont générés, car le courant de soudage est contrôlé par une impulsion basse fréquence. Le courant de crête et le
courant secondaire prédéfinis sont respectivement la valeur de crête de l’impulsion basse fréquence (valeur moyenne), et la
valeur secondaire (valeur moyenne). Pour la sélection et le réglage du paramètre de l’onde carrée AC, veuillez vous reporter
au contenu correspondant pour le soudage TIG AC à onde carrée. Pour la fréquence d’impulsion et le coefficient de durée
d’impulsion, reportez-vous au contenu correspondant pour le soudage TIG courant pulsé DC. La fréquence d’impulsion (1/T)
est assez basse, et peut être réglée entre 0,5 Hz et 5 Hz. Le coefficient de durée d’impulsion (Tp/T) peut être réglé entre 10 %
et 90 %.
8�5 Soudage TIG
Le mode de fonctionnement TIG est une sorte de stipulation spéciale, qui précise les modes de contrôle du courant de soudage
par différents fonctionnements de l’interrupteur de la torche en soudage TIG (TIG DC, TIG courant pulsé et TIG AC).
Le mode de soudage TIG doit être sélectionné en fonction des exigence techniques de l’opérateur et des habitudes de travail.
Tous les modes de fonctionnement TIG pour cet appareil sont répertoriés dans le tableau des modes de soudage TIG ci-
dessous.
