IMPORTANT! The laser-twin welding process only works when used with filler metal from
welding wire drums (1).
Lead power The two power sources are referred to as the lead power source and the trail power source
source and trail in the laser-twin welding process.

Two wire electrodes (5) and (11) are welded by a laser beam (6) in a weld pool under
a gas shroud.
The welding process is performed using two independent power sources (4) and (10).
The power sources (4) and (10) are synchronised (7).
The wire is fed via two unreeling wirefeeders (2) and a shared frontpull drive (8).
The frontpull drive (8) is controlled by a control unit (3).
Both wire electrodes are brought together in the welding torch in such a way that two
independent welding potentials (9) are available.
The lead power source is determined by the welding direction.
The t-C (Twin-Control) parameter must be set to "On" on the lead power source.
(See also "System requirements" chapter, "Software activation" section).
The lead power source specifies the frequency for the trail power source.
The wire electrode of the lead power source is the front wire electrode, in terms of the
welding direction.
