Gebruik van de toortsschakelaar
en stroom curve
1
1T/Puntlassen:
1. Druk de schakelaar in: de lasboog wordt
ontstoken en de stroom stijgt tot de vooraf
ingestelde waarde.
2. Wanneer de puntlastijd voorbij is, daalt de
stroom geleidelijk, en de lasboog stopt.
Opmerking: De puntlastijd bedraagt 1/10
van de upslope tijd.
2
2T standaard modus:
1. Druk de schakelaar in: de lasboog wordt
ontstoken en de stroom stijgt geleidelijk.
2. Laat de schakelaar los: de stroom daalt
geleidelijk en de lasboog stopt.
3. Als u de schakelaar voordat de boog stopt
opnieuw indrukt, zal de stroom weer stijgen.
Herhaal dan stap 2.
3
4T standaard modus:
1. Druk de schakelaar in: de boog
wordt ontstoken en de stroom bereikt de
beginwaarde.
2. Laat de schakelaar los: de stroom stijgt
geleidelijk.
3. Druk de schakelaar opnieuw in: de stroom
daalt tot de waarde van pilootboog stroom.
4. Laat de schakelaar los: de lasboog stopt.
Als u bovenstaande tabel leest, pas op voor volgende punten:
• Als de lasboog door HF of door de elektrode ontstoken wordt, en het maakt niet uit welke modus geselecteerd is, nadat de
boog met succes ontstoken wordt, treedt deze in beginstroom, en later in werkmodus controle.
• Sommige werkmodi gebruiken de uitgangsmodus door het indrukken van de toortsschakelaar. De gebruiker moet deze
na het lassen loslaten. Op deze manier, kan een andere lasbewerking ingevoerd worden door het indrukken van de
toortsschakelaar.
• De stroom curves in alle gebruiksmodi worden ingesteld op de veronderstelling dat de machine in DC TIG modus werkt.
Als de machine in puls TIG modus werkt, verschijnt de stroom curve in puls vorm. Als de machine in AC TIG modus werkt,
verschijnt de stroom curve in puls vorm met variabele polariteit.
• Gewoonlijk zijn 2T en 4T de meest gebruikte TIG werkmodi, die respectievelijk overeenkomen met de werkmodi 2 en 4
voor deze machine.

Operation
Torch trigger operation and current curve
1T/Spot welding mode:
①
Push the torch trigger: arc is ignited and current rises to
the preset value.
②
When the spot welding time is up, current drops
gradually, and arc stops.
Note: Spot welding time is 1/10 of the upslope time.
Standard 2T mode:
①
Push the torch trigger: arc is ignited and current rises
gradually.
②
Release the torch trigger: current drops gradually, and
arc stops.
③
If push the torch trigger again before arc stops, the
current will gradually rise again, and then turn to
②
.
Standard 4T mode:
①
Push the torch trigger: arc is ignited and current
reaches the initial value.
②
Release it: current rises gradually.
③
Push it again: current drops to pilot arc current value.
Release it: arc stops.
When reading the above table, please note:
Whether arc ignited by HF or by striking the electrode, and no matter what kind of operation mode is
selected, after arc is ignited successfully, it enters into initial current, and later into operational mode
control.
Some operation modes adopt the exit mode by pushing the torch trigger. The operator should
release it after exiting welding. In this way, another welding operation can be entered by pushing the
torch trigger.
Current curves in all operation modes are drawn on the assumption that the machine works in DC
TIG mode. If the machine works in pulsed TIG mode, the current curve appears a pulse shape; if the
machine works in AC TIG mode, the current curve appears a variable polarity pulse shape.
Customarily, the TIG operation modes most widely used are 2T and 4T, which exactly correspond to
operation mode 2 and 4 for this machine respectively.
