Trigger logic functions

You can select the trigger logic by pressing the trigger logic selection button in the control panel (X3 control panel).

2T

In 2T, pressing the trigger ignites the arc. Releasing the trigger switches the arc off.

4T

In 4T, pressing the trigger starts the pre gas, and releasing the trigger ignites the arc. Pressing the trigger again switches the arc off. Releasing the trigger ends the post gas.

If Hot start is used with 4T, pressing the trigger starts the pre gas for a predefined duration, after which the arc ignites automatically and the current raises to the Hot start level. The current is lowered to the normal welding current level once the trigger is released. If the trigger is released before the start sequence reaches the Hot start phase, the arc is ignited without Hot start.
