In AC blokgolf TIG lassen, zijn de pre-flow tijd en de post-flow tijd dezelfde als in DC TIG lassen, en de andere worden
hieronder beschreven:
• Beginstroom (I0), lasstrooom (I1) & pilootboog stroom (I2): De vooraf ingestelde waarde van die 3
parameters is ongeveer de absolute gemiddelde waarde van de praktische lasstroom, en kan aan de technische eisen van
de gebruiker aangepast worden.
• Pulsfrequentie (1/tp): Deze kan aan de technische eisen van de gebruiker aangepast worden.
• Reinigingskracht (100%*Tc/Tp): In het algemeen, in AC lassen, wanneer de elektrode als anode genomen wordt,
wordt de stroom kathodestroom genoemd. Zijn hoofdfunctie is het breken van de geoxideerde laag van het werkstuk, en de
reinigingskracht is het percentage kathodestroom tijdens de AC periode. Deze parameter is gewoonlijk 10~40 %. Als de
waarde kleiner is, is de boog concentratief, het smeltbad is smal en diep, en als de weerde groter is, is de boog dispersief,
het smeltbad is breed en ondiep.

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.

Afb. 8.16 Stroomverandering golfvorm tijdens AC puls TIG lassen
AC puls TIG lassen is bijna hetzelfde als AC blokgolf TIG lassen. Het verschil is dat in AC puls TIG lassen, varieert de lasstroom
met de puls, en een piekstroom en een secundaire stroom worden gegenereerd, omdat de lasstroom door een lage frequentie
puls gecontroleerd wordt. De vooraf ingestelde piekstroom en secundaire stroom zijn respectievelijk de piekwaarde van de lage
frequentie puls (gemiddelde waarde), en de secundaire waarde (gemiddelde waarde). Voor de selectie en de instelling van
de AC blokgolf parameter, zie de overeenkomstige inhoud van AC blokgolf TIG lassen. Voor de pulsfrequentie en de pulstijd
coëfficiënt, zie de overeenkomstige inhoud van DC puls TIG lassen. De pulsfrequentie (1/T) is nogal laag, en kan tussen 0,5
Hz en 5 Hz ingesteld worden. De pulstijd coëfficiënt (Tp/T) kan tussen 10 % en 90 % ingesteld worden.

De TIG werkmodus is een soort speciale bepaling, die de controle modi van de lasstroom bepaalt door verschillende
werkingen van de toortsschakelaar in TIG lassen (DC TIG, puls TIG en AC TIG).
De TIG werkmodus moet aan de technische eisen van de gebruiker en aan de werkgewoonten aangepast worden.
Alle TIG werkmodi voor deze machine worden in onderstaande tabel vermeld.
