Special versions
General Professional processing of specific materials requires welding programs that are specially
matched to the different materials in question. The special versions of the digital power
sources are perfectly matched to these requirements. As a result the most important weld-
ing programs can be called up directly from the operating panel. Furthermore, the power
sources are characterised by standard functions that assist the user when welding these
materials.
Alu edition The Alu edition power sources were developed for perfect and careful processing of alu-
minium. Special aluminium welding programs assist in the professional processing of alu-
minium.
The Alu edition power sources are equipped as standard with the following options:
- Special aluminium welding programs
- SynchroPulse option
CrNi edition The CrNi edition power sources were developed for perfect and careful processing of CrNi.
Special CrNi welding programs assist in the professional processing of high-grade steels.
The CrNi edition power sources are equipped as standard with the following options:
- Special CrNi welding programs
- SynchroPulse option
- TIG Comfort Stop option
- TIG welding torch connection
- Gas solenoid valve
CMT Variants In addition to conventional welding processes, the CMT variants also support the CMT
process. CMT (Cold Metal Transfer) is a special MIG short-arc process. Its special features
include low heat input and a controlled, low-current material transfer.
CMT is suitable for:
- Virtually spatter-free MIG brazing
- Welding on light-gauge sheet with minimal distortion
- Joining steel and aluminium (weld brazing)

In addition to the conventional MIG/MAG welding processes, MMA welding and the CMT
process, the CMT 4000 Advanced power source supports the improved CMT Advanced
process.
The functional principle of the CMT Advanced process is based on a combination arc with
negatively polarised CMT cycles and positively polarised CMT cycles or positively polar-
NOTE! The technical data of the special versions is identical to that of the stand-
ard power sources.
NOTE! It is not possible to install the “Uni Box” system add-on on the CrNi edition
(e.g. for the field bus connection of a robot control).
However, the CrNi edition supports a robot connection via ROB 4000 / 5000 robot
interfaces.
