5.2.1

Welding task selection

It is only possible to change the basic parameters when no welding current is flowing and any
possible access control is disabled > see 5.4 chapter.
The following welding task selection is an example of use. In general, the selection process always has
the same sequence. Signal lights (LED) will show the selected combination.
5.2.2

Hotstart

The function hot start ensures a secure igniting of the arc and a sufficient heating to the still cold parent
metal at the beginning of the welding process. The ignition takes place here with increased current (hot
start current) over a certain time (hot start time).
For parameter setting, > see 5.2.5 chapter.

The Antistick feature prevents the electrode from annealing.
Should the electrode stick, the machine automatically switches to the
minimum current within approx. one second. This prevents the electrode
from annealing. Check the welding current setting and correct for the
welding task in hand.
