Two wire electrodes (4) and (5) are welded in a weld pool in a shielding gas
environment.
The welding process is carried out via two independent power sources (1) and
(2).
The power sources are synchronized by the TWIN Controller.
The wirefeed is carried out via a wirefeeder (3) with two drive units.
The two wire electrodes are brought together in the welding torch so that
there are two independent welding potentials (6).
The lead power source is defined by the welding direction.
During pulsed-arc welding, the lead power source stipulates the frequency
for the trail power source.
When viewed in the direction of welding, the wire electrode of the lead power
source is the front wire electrode.
If the welding direction changes and the torch position remains the same,
then the trail power source becomes the lead power source.
The robot controls define lead and trail using 2 bits. Depending on the result
of this process, lead or trail will also be displayed on the power source.
