When setting up for electrode welding care must be taken that no TIG torch is
fitted. If this is not the case the display screen shows the error number “E021”.
6.4.2 Hot Start
When electrode welding, a higher current than the set welding current I1 is used
for a short time when starting welding to achieve better electrode ignition. The set
hot start determines its magnitude. Using the push and rotary encoder, the
setting is infinitely variable between 0% and 200% of the selected current I1
limited to the maximum unit current
6.4.3 Welding current I1
The welding current I1 can be continuously adjusted up to the maximum value
specific to the unit.

6.4.4 ArcForce
For a stable arc during electrode welding, it is important to support a droplet-
shaped material transfer through very short current pulses overlaid to the
selected welding current I1.
The magnitude of these current pulses is determined by the selected ArcForce
setting.
In both of the electrode types that can be selected, rutile and basic, the value can
be set stepless between 0% and 300%.
Example: ArcForce 50% and welding current I1=100A
This results in a current pulse of 150A
