Placing the machine
A
Caution!
Always stand the machine on
its feet only.
The machine draws in air at its front
and bottom, which is given off
through the ventilating slots at the
rear. Ensure an unhindered airflow.
The distance of the machine to walls
or other equipment must be at least
20 cm.

and Anti-stick functions.
and Anti-stick functions.
Hot-start function
When contacting the weld metal with the
electrode, the set welding current is
increased for a short period to ensure
that the arc will start.

This brief increase of the welding current
is limited to the maximum electrode cur-

rent.
Arc-force function
During the welding process the machine
keeps the energy (heat) brought into the
weld metal at a constant level, even if
the distance between electrode and
weld pool varies.

Anti-stick function
If the machine detects a short-circuit in
the welding process, it will switch to min-
imum current within 0.5 sec to keep the
electrode from burning out.
