The PowerMax 4.0 heralds the dawn of a new era in welding. An innovative resonance principle makes welding easier: the quick reacting characteristic curve control of the unit means that the welding result is improved even with demanding manual electrodes. In your day-to-day welding operations, you will not want to miss out on TIG contact arc ignition and Hot-Start features. All of this is combined with even greater comfort with the new POWERmax generation: reduced weight and compact size for versatile on-site handling. By adapting the power consumption to the network voltage the losses (inductive and capacitive reactance eff ects) are reduced and the power factor improved.


  • Welding with cutting-edge technology.
  • The digital resonance inverter ensures an extremely stable arc, as well as reduced spatter formation.
  • The PFC technology (Power Factor Correction) enables energy savings, extended mains cables up to approx. 100 m, as well as a more flexible input voltage range.
  • Optimised arc electrode ignition for specific application requirements and considerably reduced electrode sticking.
  • Safe connection and operating range.
  • Robust plastic housing design.
  • Increased stability.
  • Increased service life thanks to the robustly designed inner components.
  • Optimised rib framing.
