5.1.2 Welding task selection
By setting the tungsten electrode diameter
, the TIG ignition behaviour (ignition energy), machine
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 exa-
mple to reduce the ignition energy when using thin sheet metal). With the selection of the electrode dia-
meter, a minimum current limit is set that in turn affects the start, main and secondary currents. Minimum
current limits prevent an unstable arc at impermissibly low currents. If necessary, the minimum current
limits can be disabled with the parameter
in the machine configuration menu
> see 5.11 chapter
.
When using a foot-operated remote control, the minimum current limits are disabled by default.

5.1.3 Ignition correction
The ignition energy can be optimised for the welding task using the ignition correction
parameter.
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
