3.3.2 Usage of the TIG Welding Trigger
2 Stroke TIG Trigger
• 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.

• 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.
