Safety
7.3.1
DC welding with pulse start
With this type of current, the arc is ignited with plus at the burner.
Immediately after the ignition of the arc it is switched to minus. This
makes it easier to ignite even under difficult conditions (mixed gases).

DC welding
This mode corresponds to the known DC welding.
7.3.3
AC welding sinus (soft)
The arc shape is a bit softer, the arc noise a bit quieter. The frequency
is adjustable from 20 to 250 Hz, the balance from 80:20 to 20:80. The
ignitor is permanently active for AC welding.
7.3.4
AC welding rectangle (hard)
The arc shape is a bit harder and more stable. The frequency is
adjustable from 20 to 250 Hz, the balance from 80:20 to 20:80. The
