Welding task selection

The setting of the tungsten electrode diameter has a direct influence on the machine functionality, TIG
ignition behaviour and minimum current limits. The ignition energy is controlled by the set electrode
diameter. 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.
