The protective gas must start to flow before the arc is struck in order to provide time
for it to cover the weld position. A suitable preflow time must therefore be loaded
into the system, and this is done by entering the required time, in seconds, into the
selected field.
Times between 1 and 99 seconds can be entered. The default value is 1 second.
