CMT 4000
Advanced 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
polarised pulse cycles. Special features are targeted heat input, a higher deposition rate,
better gap bridging properties, precise droplet detachment and an extremely stable arc.
CMT Advanced is suitable for:
-
joining thin sheets with outstanding gap bridging properties
- High-strength steels with low heat input
- Spots: precisely defined drop volumes and defined heat input
- Root passes with no pool support
- Brazing high-strength and ultra high-strength steels
TIME 5000 Digital Concept
As a universal power source, the TIME 5000 Digital is particularly suited for manual
applications. In addition to conventional welding processes, the TIME 5000 Digital also
supports the TIME high-performance welding process.
Functional principle
Compared with conventional MIG/MAG processes, the following features bring about
faster welding speeds, with an increase in deposition rate of up to 30%:
-
Power module with high voltage reserves
- High performance welding programs
- Specially selected shielding gases
- High-performance wire-feed unit with water-cooled disc armature motor for wire feed
speeds of up to 30 m/min
- TIME welding torch with dual circuit cooling system
Application
Anywhere where long weld seams, large seam cross-sections and controlled heat input
are required, e.g.:
-
Mechanical engineering
- Steel engineering
- Crane construction
- Shipbuilding
- Boiler manufacture
The new TIME 5000 Digital power source can also be used in automated applications.
Material types
The high-performance welding process is especially suitable for
-
unalloyed steels
- low-alloy steels EN 10027
- fine-grained structural steels up to 890 N/mm²
- steels resistant to low temperatures
Yard edition Yard edition power sources are designed especially for use in shipyards and offshore
applications. The welding programs are designed primarily for steel and CrNi applica-
tions with solid and flux cored wires.
Steel edition Steel edition power sources are designed specifically for use in the steel sector. The spe-
cial characteristics can be set on the control panel - both for standard and pulsed arcs.
