Welding task selection

The setting of the tungsten electrode diameter has a direct influence on the machine functionality, TIG ig-
nition behaviour and minimum current limits. The ignition energy is controlled by the set electrode diame-
ter. Smaller electrode diameters requires less ignition current and less ignition current time than greater
electrode diameters. The set value should correspond to the tungsten electrode diameter. The value can
also be set to meet individual requirements, e.g. for thin panels a smaller diameter is recommended to
reduce the ignition energy.
