Fronius VarioSynergic 4000

  • Stepped control up to 400 A

  • Microprocessor-controlled synergic operation

  • Welds unalloyed, low-alloy and high-alloy steels and flux cored wires

At 400 A, the VarioSynergic 4000 is a stepped and microprocessor-controlled MIG/MAG power source with an integral 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 welds unalloyed and low-alloy steels as well as high-alloy steels and flux cored wires. The integral wire-feed unit makes portable applications easier.
