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 "Uco"
parameter, the welding voltage can be limited to a value that makes it possible to end the
welding process simply by lifting the rod electrode slightly.

IMPORTANT!

If the welding process often ends unintentionally during welding, set the

Uco parameter to a higher value.
