- Stepped control up to 400 A
- Microprocessor-controlled synergic operation
- Separate wire-feed unit
At 400 A, the VarioSynergic 4000-2 is a stepped and microprocessor-controlled MIG/MAG power source with separate wire-feed unit and 4-roll drive. Synergic operation makes welding the easiest thing in the world. Set the sheet thickness and filler metal, and away you go! Robust and reliable, the VarioSynergic is suitable for heavy steel, machine and equipment construction, plant and container construction, and for use in workshops.
The VarioSynergic 4000-2 welds unalloyed and low-alloy steels as well as high-alloy steels and flux cored wires.
