Functional principle of TimeTwin Digital: Separate welding potential
Leading power In the "TimeTwin Digital" process we refer to the two power sources as the "lea-
source and trai- ding" power source and the "trailing" power source, respectively.

Two wire electrodes are welded in a single weld-pool, under a shielding-gas
atmosphere.
The wire is fed by two separate wirefeeders. These wirefeeders, in turn, are
powered by two power sources, each of which is independent of the other.
The two power sources are synchronised.
The two wire electrodes are brought together in the welding torch in such a
way that there are two separate welding potentials.

Depending on the direction of welding, one of the two power sources will be
defined as the leading power source.
The definition of which is the leading power source is made by means of "Pa-
rameter t-C" (Twin Control). On the leading power source, Parameter t-C is
set to "On" (please also see the section headed "System requirements", sub-
section: "Enabling the software").
The leading power source specifies the frequency for the trailing power
source.
Seen in the direction of welding, the wire electrode of the leading power
source is the "front" wire electrode.
When you reverse the direction of welding, leaving the torch position unch-
anged, the trailing power source becomes the leading power source.
