5.1.1.2 Setting the operating point (welding output)
This control works according to the twin-knob operation principle. To set the operating point, only the wire
speed and the welding voltage need to be set according to the material and the electrode diameter.

5.1.1.3 Welding parameter ignition time "tZn" diagram
NOTE
In the ignition time, the wire feed continues to run at creep speed after the arc is ignited;
the ignition behaviour is improved with the optimum setting.
The process described below is always used if there is a pause between welding processes of
not less than 1.5 seconds.
