Welding task selection

By setting the tungsten electrode diameter
functions and minimum current limit are preset optimally. Smaller electrode diameters require less ignition
energy than larger electrode diameters.
If necessary, the ignition energy > see 5.1.3 chapter can also be adapted to each welding task (for
example to reduce the ignition energy when using thin sheet metal). With the selection of the electrode
diameter, a minimum current limit is set that in turn affects the start, main and secondary currents. Mini-
mum current limits prevent an unstable arc at impermissibly low currents. If necessary, the minimum cur-
rent limits can be disabled with the parameter
When using a foot-operated remote control, the minimum current limits are disabled by default.

Ignition correction

The ignition energy can be optimised for the welding task using the ignition correction
Should it be necessary to set the ignition energy outside the existing correction limits, this can also be
configured manually for ignition current and ignition current time > see 5.1.4 chapter.
