Final current : It is the current with which the welding arc will end. When
the trigger is no longer depressed in 2T, or the trigger is depressed again
in 4T, the current will gradually decrease from the working current until it
reaches the final current and is interrupted, within the period configured in
the descent ramp or time of descent .
Ramp up or rise time : Configurable from 0 to 10s. It is the time in which,
since the arc starts, the current rises from the initial current to the working
current.
Ramp down or fall time : Configurable from 0 to 10s. It is the time when,
after the trigger is released from 2T, or the trigger is pressed again at 4T
to end the weld, the current drops from the working current to the final
current.
The order in which the operations configured in the TIG welding curve are executed is as
follows:
FOR 2T:
Trigger is pressed (keeping it pressed) → Pre-gas (time) → Arc start (HF or Lift) → Electric
arc activation with initial current → Ramp up (time) → Welding application (with working
current) → Release the trigger → Ramp down (time) → Current drops to final current and
arc is deactivated → Post-gas (time).
FOR 4T:
Trigger is pressed and released → Pre-gas (time) → Arc start (HF or Lift) → Electric arc
activation with initial current → Ramp up (time) → Welding application (with working
current) → Trigger is pressed and released → Ramp down (time) → Current drops to final
current and arc is deactivated → Post-gas (time).
