3.3.2 Usage Of The TIG Welding Modes
2 Stroke TIG Welding
Push the torch trigger and do not release your finger. Current starts with start current after pre gas-flow period and increases according to the up-slope
time adjustment and reaches to value of the main current. Welding goes on with the main current as long as the torch trigger is kept pushed. After
releasing the trigger, current decreases according to down-slope time adjustment and reaches to final current, after post gas-flow period the operation
ends.
4 Stroke TIG Welding
Spot TIG Welding
When torch trigger is pushed, following the pre-gas flow, initial current starts and when the trigger is released the currrent ramp leads to the welding
current. If DC PULSE mode is selected, according to the adjusted frequency, welding current oscillates between this reached welding current and the
base current. If the trigger will be pushed and released more than 1 second, current decreases according to down-ramp adjustment, reaches to the
final current, after post gas, welding ends.
Base current is generally used for repairing and cooling during welding and crater filling at the finishing of the welding beads. Either during DC or
during Pulsed DC welding if the trigger is pushed and released less than 1 second, DC base current will be on.
If the trigger will be pushed less than 1 second, welder will go back to the existing welding mode and parameters, but if the trigger will be pushed and
released more than 1 second, welding will be finished by following the down-ramp, final current and post-gas.
When the torch trigger is pushed, main current starts immediately and goes on as long as the torch trigger is kept pushed. Welding goes on during spot
welding time. After spot welding time is over, current stops immediately.
