If the arc length changes (e.g. in accordance with the load line (2)) the resulting operating
point will be the point where the corresponding characteristic (4), (5) or (6) intersects with
the load line (2).
Applies to characteristics (5) and (6): Depending upon the welding voltage (arc length), the
welding current (I) will also become either smaller or larger, even though the value set for
I
H
remains the same.

As the arc becomes shorter, the welding voltage may drop so far that the rod electrode will
tend to stick. This may also cause the rod electrode to burn out.
The anti-stick function prevents the electrode from burning out. If the rod electrode begins
to stick, the power source switches the welding current off after 1.5 seconds. After the rod
electrode has been lifted off the workpiece, the welding process can be continued without
any problems.

electrode.
Setting range: 20.0 - 90.0 V
Factory setting: 90.0 V
The arc length depends on the welding voltage. To end the welding process, it is usually
necessary to significantly lift the rod electrode away from the workpiece. With the break-
voltage parameter, the welding voltage can be limited to a value that makes it possible to
end the welding operation simply by lifting the rod electrode slightly.
IMPORTANT! If, during welding, you often find that the welding operation is ended unin-
tentionally, increase the value of the break voltage.
Process parame-
ters for TIG setup
The following process parameters can be set and displayed for TIG welding:

Setting range: off / 0.1 - 2.0 V
Factory setting: 0.8 V
At the end of the welding operation, the welding current is switched off automatically if the
arc length increases by more than a defined amount. This prevents the arc being unnec-
essarily elongated when the TIG gas-valve torch is lifted off the workpiece.
