Pressing the trigger will start pre-gas. When the wire touches the workpiece a pulse boots the arc and the the
welding process starts. When you stop pressing the trigger, the wire feeder stops working and a current pulse will
cut the wire, and will be followed by post-gas. As long as the post gas is not finished, you can pull the trigger to
carry on the welding (delay in manual). To modify the parameters you have to wait until the end of the post gas.
