Welding is started by pressing the torch trigger and ends when the same is
released.
Appropriate mode and perform long-term welding. Starting and stopping
are controlled by pressing and releasing the torch trigger.
When the arc strikes, the current is set to the first level. As long as the torch
trigger is pressed, the current remains on the first level. Upon releasing the
torch trigger, the current passes from first to second level within the slope
time; once the second level is reached, this is maintained. In order to pass
to the third current level, simply press the torch trigger and the current is
adjusted to the fourth value selected within the set slope time. When the
torch trigger is released welding stops and the post-flow procedure is run.
When the torch trigger is pressed and released, the torch switches between
two preset levels as many times as the operator wishes. Welding stops
when the operator holds the torch trigger continually pressed for at least 1
second..
